# 总体步骤 #

搜索镜像

拉取镜像

查看镜像

启动镜像

停止容器

移除容器

# 安装tomcat #

docker hub 上面查找tomcat镜像-docker search tomcat

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3BzaGRoeA_size_16_color_FFFFFF_t_70][]

从docker hub上拉取tomcat镜像到本地-docker pull tomcat

1、官网命令

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3BzaGRoeA_size_16_color_FFFFFF_t_70 1][]

2、拉取完成

使用tomcat镜像创建容器-也叫运行镜像

docker run -it -p 8080:8080 tomcat

-p 主机端口:docker容器端口

-p 随机分配端口

-i:交互

-t:终端

## 安装mysql ##

docker hub上面查找mysql镜像

从docker hub上（阿里云加速器）拉取mysql镜像到本地标签为5.6

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3BzaGRoeA_size_16_color_FFFFFF_t_70 4][]

使用mysql5.6镜像创建容器（也叫运行镜像）

使用mysql镜像

docker run -p 12345:3306 --name mysql -v /zzyyuse/mysql/conf:/etc/mysql/conf.d -v /zzyyuse/mysql/logs:/logs -v /zzyyuse/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6
     
    命令说明：
    -p 12345:3306：将主机的12345端口映射到docker容器的3306端口。
    --name mysql：运行服务名字
    -v /zzyyuse/mysql/conf:/etc/mysql/conf.d ：将主机/zzyyuse/mysql录下的conf/my.cnf 挂载到容器的 /etc/mysql/conf.d
    -v /zzyyuse/mysql/logs:/logs：将主机/zzyyuse/mysql目录下的 logs 目录挂载到容器的 /logs。
    -v /zzyyuse/mysql/data:/var/lib/mysql ：将主机/zzyyuse/mysql目录下的data目录挂载到容器的 /var/lib/mysql 
    -e MYSQL_ROOT_PASSWORD=123456：初始化 root 用户的密码。
    -d mysql:5.6 : 后台程序运行mysql5.6
    
    
    
    docker exec -it MySQL运行成功后的容器ID     /bin/bash

外部win10也来连接运行在docker 上的mysql服务

备份数据小测试（可以不做）

docker exec myql服务容器ID sh -c ' exec mysqldump --all-databases -uroot -p"123456" ' > /zzyyuse/all-databases.sql

## 安装redis ##

从docker hub上（阿里云加速器）拉取redis镜像到本地标签为3.2

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3BzaGRoeA_size_16_color_FFFFFF_t_70 6][]

使用redis3.2镜像创建容器（也叫运行镜像）

使用镜像

docker run -p 6379:6379 -v /zzyyuse/myredis/data:/data -v /zzyyuse/myredis/conf/redis.conf:/usr/local/etc/redis/redis.conf  -d redis:3.2 redis-server /usr/local/etc/redis/redis.conf --appendonly yes

在主机/zzyyuse/myredis/conf/redis.conf目录下新建redis.conf文件

vim /zzyyuse/myredis/conf/redis.conf/redis.conf

# Redis configuration file example.
    
    #
    
    # Note that in order to read the configuration file, Redis must be
    
    # started with the file path as first argument:
    
    #
    
    # ./redis-server /path/to/redis.conf
    
     
    
    # Note on units: when memory size is needed, it is possible to specify
    
    # it in the usual form of 1k 5GB 4M and so forth:
    
    #
    
    # 1k => 1000 bytes
    
    # 1kb => 1024 bytes
    
    # 1m => 1000000 bytes
    
    # 1mb => 1024*1024 bytes
    
    # 1g => 1000000000 bytes
    
    # 1gb => 1024*1024*1024 bytes
    
    #
    
    # units are case insensitive so 1GB 1Gb 1gB are all the same.
    
    ################################## INCLUDES ###################################
    
     
    
    # Include one or more other config files here.  This is useful if you
    
    # have a standard template that goes to all Redis servers but also need
    
    # to customize a few per-server settings.  Include files can include
    
    # other files, so use this wisely.
    
    #
    
    # Notice option "include" won't be rewritten by command "CONFIG REWRITE"
    
    # from admin or Redis Sentinel. Since Redis always uses the last processed
    
    # line as value of a configuration directive, you'd better put includes
    
    # at the beginning of this file to avoid overwriting config change at runtime.
    
    #
    
    # If instead you are interested in using includes to override configuration
    
    # options, it is better to use include as the last line.

    # By default, if no "bind" configuration directive is specified, Redis listens
    
    # for connections from all the network interfaces available on the server.
    
    # It is possible to listen to just one or multiple selected interfaces using
    
    # the "bind" configuration directive, followed by one or more IP addresses.
    
    #
    
    # Examples:
    
    #
    
    # bind 192.168.1.100 10.0.0.1
    
    # bind 127.0.0.1 ::1
    
    #
    
    # ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
    
    # internet, binding to all the interfaces is dangerous and will expose the
    
    # instance to everybody on the internet. So by default we uncomment the
    
    # following bind directive, that will force Redis to listen only into
    
    # the IPv4 lookback interface address (this means Redis will be able to
    
    # accept connections only from clients running into the same computer it
    
    # is running).
    
    #
    
    # IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
    
    # JUST COMMENT THE FOLLOWING LINE.
    
    # ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    
    #bind 127.0.0.1
    
     
    
    # Protected mode is a layer of security protection, in order to avoid that
    
    # Redis instances left open on the internet are accessed and exploited.
    
    #
    
    # When protected mode is on and if:
    
    #
    
    # 1) The server is not binding explicitly to a set of addresses using the
    
    #    "bind" directive.
    
    # 2) No password is configured.
    
    #
    
    # The server only accepts connections from clients connecting from the
    
    # IPv4 and IPv6 loopback addresses 127.0.0.1 and ::1, and from Unix domain
    
    # sockets.
    
    #
    
    # By default protected mode is enabled. You should disable it only if
    
    # you are sure you want clients from other hosts to connect to Redis

    # On other kernels the period depends on the kernel configuration.

    ################################# REPLICATION #################################
    
     
    
    # Master-Slave replication. Use slaveof to make a Redis instance a copy of
    
    # another Redis server. A few things to understand ASAP about Redis replication.
    
    #
    
    # 1) Redis replication is asynchronous, but you can configure a master to
    
    #    stop accepting writes if it appears to be not connected with at least
    
    #    a given number of slaves.
    
    # 2) Redis slaves are able to perform a partial resynchronization with the
    
    #    master if the replication link is lost for a relatively small amount of
    
    #    time. You may want to configure the replication backlog size (see the next
    
    #    sections of this file) with a sensible value depending on your needs.
    
    # 3) Replication is automatic and does not need user intervention. After a
    
    #    network partition slaves automatically try to reconnect to masters
    
    #    and resynchronize with them.
    
    #
    
    # slaveof <masterip> <masterport>
    
     
    
    # If the master is password protected (using the "requirepass" configuration
    
    # directive below) it is possible to tell the slave to authenticate before
    
    # starting the replication synchronization process, otherwise the master will
    
    # refuse the slave request.
    
    #
    
    # masterauth <master-password>
    
     
    
    # When a slave loses its connection with the master, or when the replication
    
    # is still in progress, the slave can act in two different ways:
    
    #
    
    # 1) if slave-serve-stale-data is set to 'yes' (the default) the slave will
    
    #    still reply to client requests, possibly with out of date data, or the
    
    #    data set may just be empty if this is the first synchronization.
    
    #
    
    # 2) if slave-serve-stale-data is set to 'no' the slave will reply with
    
    #    an error "SYNC with master in progress" to all the kind of commands
    
    #    but to INFO and SLAVEOF.
    
    #
    
    slave-serve-stale-data yes
    
     
    
    # You can configure a slave instance to accept writes or not. Writing against
    
    # a slave instance may be useful to store some ephemeral data (because data
    
    # written on a slave will be easily deleted after resync with the master) but
    
    # may also cause problems if clients are writing to it because of a
    
    # misconfiguration.
    
    #
    
    # Since Redis 2.6 by default slaves are read-only.
    
    #
    
    # Note: read only slaves are not designed to be exposed to untrusted clients
    
    # on the internet. It's just a protection layer against misuse of the instance.
    
    # Still a read only slave exports by default all the administrative commands
    
    # such as CONFIG, DEBUG, and so forth. To a limited extent you can improve
    
    # security of read only slaves using 'rename-command' to shadow all the
    
    # administrative / dangerous commands.
    
    slave-read-only yes
    
     
    
    # Replication SYNC strategy: disk or socket.
    
    #
    
    # -------------------------------------------------------
    
    # WARNING: DISKLESS REPLICATION IS EXPERIMENTAL CURRENTLY
    
    # -------------------------------------------------------
    
    #
    
    # New slaves and reconnecting slaves that are not able to continue the replication
    
    # process just receiving differences, need to do what is called a "full
    
    # synchronization". An RDB file is transmitted from the master to the slaves.
    
    # The transmission can happen in two different ways:
    
    #
    
    # 1) Disk-backed: The Redis master creates a new process that writes the RDB
    
    #                 file on disk. Later the file is transferred by the parent
    
    #                 process to the slaves incrementally.
    
    # 2) Diskless: The Redis master creates a new process that directly writes the
    
    #              RDB file to slave sockets, without touching the disk at all.
    
    #
    
    # With disk-backed replication, while the RDB file is generated, more slaves
    
    # can be queued and served with the RDB file as soon as the current child producing
    
    # the RDB file finishes its work. With diskless replication instead once
    
    # the transfer starts, new slaves arriving will be queued and a new transfer
    
    # will start when the current one terminates.
    
    #
    
    # When diskless replication is used, the master waits a configurable amount of
    
    # time (in seconds) before starting the transfer in the hope that multiple slaves
    
    # will arrive and the transfer can be parallelized.
    
    #
    
    # With slow disks and fast (large bandwidth) networks, diskless replication
    
    # works better.
    
    repl-diskless-sync no
    
     
    
    # When diskless replication is enabled, it is possible to configure the delay
    
    # the server waits in order to spawn the child that transfers the RDB via socket
    
    # to the slaves.

    # A Redis master is able to list the address and port of the attached

    # "ROLE" command of a masteer.

    # The listed IP and address normally reported by a slave is obtained
    
    # in the following way:
    
    #
    
    #   IP: The address is auto detected by checking the peer address
    
    #   of the socket used by the slave to connect with the master.
    
    #
    
    #   Port: The port is communicated by the slave during the replication
    
    #   handshake, and is normally the port that the slave is using to
    
    #   list for connections.
    
    #
    
    # However when port forwarding or Network Address Translation (NAT) is
    
    # used, the slave may be actually reachable via different IP and port
    
    # pairs. The following two options can be used by a slave in order to
    
    # report to its master a specific set of IP and port, so that both INFO
    
    # and ROLE will report those values.

    # allkeys-random -> remove a random key, any key
    
    # volatile-ttl -> remove the key with the nearest expire time (minor TTL)
    
    # noeviction -> don't expire at all, just return an error on write operations
    
    #
    
    # Note: with any of the above policies, Redis will return an error on write
    
    #       operations, when there are no suitable keys for eviction.
    
    #
    
    #       At the date of writing these commands are: set setnx setex append

    # good enough in many applications, but an issue with the Redis process or
    
    # a power outage may result into a few minutes of writes lost (depending on
    
    # the configured save points).
    
    #
    
    # The Append Only File is an alternative persistence mode that provides
    
    # much better durability. For instance using the default data fsync policy
    
    # (see later in the config file) Redis can lose just one second of writes in a
    
    # dramatic event like a server power outage, or a single write if something
    
    # wrong with the Redis process itself happens, but the operating system is
    
    # still running correctly.
    
    #
    
    # AOF and RDB persistence can be enabled at the same time without problems.
    
    # If the AOF is enabled on startup Redis will load the AOF, that is the file

    #
    
    # Redis supports three different modes:
    
    #
    
    # no: don't fsync, just let the OS flush the data when it wants. Faster.

    # everysec: fsync only one time every second. Compromise.
    
    #
    
    # The default is "everysec", as that's usually the right compromise between
    
    # speed and data safety. It's up to you to understand if you can relax this to
    
    # "no" that will let the operating system flush the output buffer when
    
    # it wants, for better performances (but if you can live with the idea of
    
    # some data loss consider the default persistence mode that's snapshotting),

    # There is no simple way for a slave to actually have a exact measure of
    
    # its "data age", so the following two checks are performed:
    
    #
    
    # 1) If there are multiple slaves able to failover, they exchange messages
    
    #    in order to try to give an advantage to the slave with the best
    
    #    replication offset (more data from the master processed).
    
    #    Slaves will try to get their rank by offset, and apply to the start
    
    #    of the failover a delay proportional to their rank.
    
    #
    
    # 2) Every single slave computes the time of the last interaction with
    
    #    its master. This can be the last ping or command received (if the master
    
    #    is still in the "connected" state), or the time that elapsed since the
    
    #    disconnection with the master (if the replication link is currently down).
    
    #    If the last interaction is too old, the slave will not try to failover
    
    #    at all.
    
    #
    
    # The point "2" can be tuned by user. Specifically a slave will not perform
    
    # the failover if, since the last interaction with the master, the time
    
    # elapsed is greater than:
    
    #
    
    #   (node-timeout * slave-validity-factor) + repl-ping-slave-period
    
    #
    
    # So for example if node-timeout is 30 seconds, and the slave-validity-factor
    
    # is 10, and assuming a default repl-ping-slave-period of 10 seconds, the
    
    # slave will not try to failover if it was not able to talk with the master
    
    # for longer than 310 seconds.
    
    #
    
    # A large slave-validity-factor may allow slaves with too old data to failover
    
    # a master, while a too small value may prevent the cluster from being able to
    
    # elect a slave at all.
    
    #
    
    # For maximum availability, it is possible to set the slave-validity-factor
    
    # to a value of 0, which means, that slaves will always try to failover the
    
    # master regardless of the last time they interacted with the master.
    
    # (However they'll always try to apply a delay proportional to their
    
    # offset rank).
    
    #
    
    # Zero is the only value able to guarantee that when all the partitions heal
    
    # the cluster will always be able to continue.
    
    #
    
    # cluster-slave-validity-factor 10
    
     
    
    # Cluster slaves are able to migrate to orphaned masters, that are masters
    
    # that are left without working slaves. This improves the cluster ability
    
    # to resist to failures as otherwise an orphaned master can't be failed over
    
    # in case of failure if it has no working slaves.
    
    #
    
    # Slaves migrate to orphaned masters only if there are still at least a
    
    # given number of other working slaves for their old master. This number
    
    # is the "migration barrier". A migration barrier of 1 means that a slave
    
    # will migrate only if there is at least 1 other working slave for its master
    
    # and so forth. It usually reflects the number of slaves you want for every
    
    # master in your cluster.
    
    #
    
    # Default is 1 (slaves migrate only if their masters remain with at least
    
    # one slave). To disable migration just set it to a very large value.
    
    # A value of 0 can be set but is useful only for debugging and dangerous
    
    # in production.
    
    #
    
    # cluster-migration-barrier 1
    
     
    
    # By default Redis Cluster nodes stop accepting queries if they detect there
    
    # is at least an hash slot uncovered (no available node is serving it).
    
    # This way if the cluster is partially down (for example a range of hash slots
    
    # are no longer covered) all the cluster becomes, eventually, unavailable.
    
    # It automatically returns available as soon as all the slots are covered again.
    
    #
    
    # However sometimes you want the subset of the cluster which is working,
    
    # to continue to accept queries for the part of the key space that is still
    
    # covered. In order to do so, just set the cluster-require-full-coverage
    
    # option to no.
    
    #
    
    # cluster-require-full-coverage yes

    ################################## SLOW LOG ###################################
    
     
    
    # The Redis Slow Log is a system to log queries that exceeded a specified
    
    # execution time. The execution time does not include the I/O operations
    
    # like talking with the client, sending the reply and so forth,
    
    # but just the time needed to actually execute the command (this is the only
    
    # stage of command execution where the thread is blocked and can not serve
    
    # other requests in the meantime).
    
    #
    
    # You can configure the slow log with two parameters: one tells Redis
    
    # what is the execution time, in microseconds, to exceed in order for the
    
    # command to get logged, and the other parameter is the length of the
    
    # slow log. When a new command is logged the oldest one is removed from the
    
    # queue of logged commands.
    
     
    
    # The following time is expressed in microseconds, so 1000000 is equivalent
    
    # to one second. Note that a negative number disables the slow log, while
    
    # a value of zero forces the logging of every command.

    ################################ LATENCY MONITOR ##############################
    
     
    
    # The Redis latency monitoring subsystem samples different operations
    
    # at runtime in order to collect data related to possible sources of
    
    # latency of a Redis instance.
    
    #
    
    # Via the LATENCY command this information is available to the user that can
    
    # print graphs and obtain reports.
    
    #
    
    # The system only logs operations that were performed in a time equal or
    
    # greater than the amount of milliseconds specified via the
    
    # latency-monitor-threshold configuration directive. When its value is set
    
    # to zero, the latency monitor is turned off.
    
    #
    
    # By default latency monitoring is disabled since it is mostly not needed
    
    # if you don't have latency issues, and collecting data has a performance

    ############################# EVENT NOTIFICATION ##############################
    
     
    
    # Redis can notify Pub/Sub clients about events happening in the key space.
    
    # This feature is documented at http://redis.io/topics/notifications
    
    #
    
    # For instance if keyspace events notification is enabled, and a client
    
    # performs a DEL operation on key "foo" stored in the Database 0, two
    
    # messages will be published via Pub/Sub:
    
    #
    
    # PUBLISH __keyspace@0__:foo del
    
    # PUBLISH __keyevent@0__:del foo
    
    #
    
    # It is possible to select the events that Redis will notify among a set
    
    # of classes. Every class is identified by a single character:
    
    #
    
    #  K     Keyspace events, published with __keyspace@<db>__ prefix.
    
    #  E     Keyevent events, published with __keyevent@<db>__ prefix.
    
    #  g     Generic commands (non-type specific) like DEL, EXPIRE, RENAME, ...
    
    #  $     String commands
    
    #  l     List commands
    
    #  s     Set commands
    
    #  h     Hash commands
    
    #  z     Sorted set commands
    
    #  x     Expired events (events generated every time a key expires)
    
    #  e     Evicted events (events generated when a key is evicted for maxmemory)
    
    #  A     Alias for g$lshzxe, so that the "AKE" string means all the events.
    
    #
    
    #  The "notify-keyspace-events" takes as argument a string that is composed
    
    #  of zero or multiple characters. The empty string means that notifications
    
    #  are disabled.
    
    #
    
    #  Example: to enable list and generic events, from the point of view of the
    
    #           event name, use:
    
    #
    
    #  notify-keyspace-events Elg
    
    #
    
    #  Example 2: to get the stream of the expired keys subscribing to channel
    
    #             name __keyevent@0__:expired use:
    
    #
    
    #  notify-keyspace-events Ex
    
    #
    
    #  By default all notifications are disabled because most users don't need
    
    #  this feature and the feature has some overhead. Note that if you don't
    
    #  specify at least one of K or E, no events will be delivered.
