### 拉取zookeeper镜像 ###

*  语法：`docker pull zookeeper`  
    这是拉取的最新版本的官方镜像，也可以选择其它版本的镜像
 *  示例：

[root@izbp13xko46hud9vfr5s94z /]# docker pull zookeeper 
    Using default tag: latest
    latest: Pulling from library/zookeeper
    8e3ba11ec2a2: Pull complete 
    311ad0da4533: Pull complete 
    391a6a6b3651: Pull complete 
    104bcdeaa0fa: Pull complete 
    a212fb0da7e6: Pull complete 
    453117a52ac9: Pull complete 
    83b030e7117e: Pull complete 
    Digest: sha256:48f64faf49473825f84574e04b0b74008b0ee23770405e0e7d8262c172b9d826
    Status: Downloaded newer image for zookeeper:latest
    [root@izbp13xko46hud9vfr5s94z /]#

### 启动zookeeper容器实例 ###

*  语法：`docker run --name zookeeper --restart always -d zookeeper`  
    `--restart always`：始终重新启动zookeeper
 *  示例：

[root@izbp13xko46hud9vfr5s94z /]# docker run --name zookeeper --restart always -d zookeeper
    b6838b7ca21a23fd80037e4e7b6d364ecf7613f39ecaee01cb26cb44455514dc
    [root@izbp13xko46hud9vfr5s94z /]#

### 查看当前zookeeper容器实例的进程信息 ###

*  语法：`docker top zookeeper`  
    `zookeeper`：表示当前`zookeeper`实例的名称，通过`--name`指定，也可以使用容器ID来替代
 *  示例：

docker top zookeeper
    UID                 PID                 PPID                C                   STIME               TTY                 TIME                CMD
    1000                6737                6715                0                   13:49               ?                   00:00:01            /usr/lib/jvm/java-1.8-openjdk/jre/bin/java -Dzookeeper.log.dir=. -Dzookeeper.root.logger=INFO,CONSOLE -cp /zookeeper-3.4.13/bin/../build/classes:/zookeeper-3.4.13/bin/../build/lib/*.jar:/zookeeper-3.4.13/bin/../lib/slf4j-log4j12-1.7.25.jar:/zookeeper-3.4.13/bin/../lib/slf4j-api-1.7.25.jar:/zookeeper-3.4.13/bin/../lib/netty-3.10.6.Final.jar:/zookeeper-3.4.13/bin/../lib/log4j-1.2.17.jar:/zookeeper-3.4.13/bin/../lib/jline-0.9.94.jar:/zookeeper-3.4.13/bin/../lib/audience-annotations-0.5.0.jar:/zookeeper-3.4.13/bin/../zookeeper-3.4.13.jar:/zookeeper-3.4.13/bin/../src/java/lib/*.jar:/conf: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false org.apache.zookeeper.server.quorum.QuorumPeerMain /conf/zoo.cfg
    [root@izbp13xko46hud9vfr5s94z /]#

也可以通过`ps -ef | grep zookeeper`来查看进程信息，示例如下：

[root@izbp13xko46hud9vfr5s94z /]# ps -ef | grep zookeeper 
    1000      6737  6715  0 13:49 ?        00:00:01 /usr/lib/jvm/java-1.8-openjdk/jre/bin/java -Dzookeeper.log.dir=. -Dzookeeper.root.logger=INFO,CONSOLE -cp /zookeeper-3.4.13/bin/../build/classes:/zookeeper-3.4.13/bin/../build/lib/*.jar:/zookeeper-3.4.13/bin/../lib/slf4j-log4j12-1.7.25.jar:/zookeeper-3.4.13/bin/../lib/slf4j-api-1.7.25.jar:/zookeeper-3.4.13/bin/../lib/netty-3.10.6.Final.jar:/zookeeper-3.4.13/bin/../lib/log4j-1.2.17.jar:/zookeeper-3.4.13/bin/../lib/jline-0.9.94.jar:/zookeeper-3.4.13/bin/../lib/audience-annotations-0.5.0.jar:/zookeeper-3.4.13/bin/../zookeeper-3.4.13.jar:/zookeeper-3.4.13/bin/../src/java/lib/*.jar:/conf: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false org.apache.zookeeper.server.quorum.QuorumPeerMain /conf/zoo.cfg
    root      7301  6175  0 13:58 pts/0    00:00:00 grep --color=auto zookeeper
    [root@izbp13xko46hud9vfr5s94z /]#

### 停止zookeeper实例进程 ###

*  语法：`docker stop zookeeper`
 *  示例：

[root@izbp13xko46hud9vfr5s94z /]# docker stop zookeeper 
    zookeeper
    [root@izbp13xko46hud9vfr5s94z /]#

### 启动、重启zookeeper实例进程 ###

*  启动语法：`docker start zookeeper`
 *  重启语法：`docker restart zookeeper`
 *  示例：

[root@izbp13xko46hud9vfr5s94z /]# docker start zookeeper
    zookeeper
    [root@izbp13xko46hud9vfr5s94z /]# docker restart zookeeper 
    zookeeper
    [root@izbp13xko46hud9vfr5s94z /]#

### 查看zookeeper进程日志 ###

*  语法：`docker logs -f zookeeper`
 *  示例：

[root@izbp13xko46hud9vfr5s94z /]# docker logs -f zookeeper

### 使用zk 命令行客户端连接zk ###

*  语法：`docker run -it --rm --link zookeeper:zookeeper zookeeper zkCli.sh -server zookeeper`  
    说明：`-server zookeeper`是启动`zkCli.sh`的参数

### 杀死zookeeper实例进程 ###

*  语法：`docker kill -s KILL zookeeper`
 *  示例：

[root@izbp13xko46hud9vfr5s94z /]# docker kill -s KILL zookeeper 
    zookeeper
    [root@izbp13xko46hud9vfr5s94z /]#

### 移除zookeeper实例 ###

*  语法：`docker rm -f -v zookeeper`
 *  示例：

[root@izbp13xko46hud9vfr5s94z /]# docker rm -f -v zookeeper 
    zookeeper
    [root@izbp13xko46hud9vfr5s94z /]#

## 集群方式安装 ##

集群方式选择使用`docker-compose`来完成。  
编写配置文件，并将其命名为：`docker-compose.yml`（`docker-compose`默认配置文件名）  
配置文件内容：

version: '2'
    services:
        zoo1:
            image: zookeeper
            restart: always
            container_name: zoo1
            ports:
                - "2181:2181"
            environment:
                ZOO_MY_ID: 1
                ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888
    
        zoo2:
            image: zookeeper
            restart: always
            container_name: zoo2
            ports:
                - "2182:2181"
            environment:
                ZOO_MY_ID: 2
                ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888
    
        zoo3:
            image: zookeeper
            restart: always
            container_name: zoo3
            ports:
                - "2183:2181"
            environment:
                ZOO_MY_ID: 3
                ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

此配置文件表示，Docker需要启动三个zookeeper实例，并将2181，2182，2183三个端口号映射到容器内的2181这个端口上。  
`ZOO_MY_ID`：表示zk服务的ID, 取值为1-255之间的整数，且必须唯一  
`ZOO_SERVERS`：表示zk集群的主机列表

### 启动zookeeper集群 ###

*  语法：`docker-compose up -d`  
    该命令执行需要在`docker-compose`配置文件的目录下执行。
 *  示例：

[root@izbp13xko46hud9vfr5s94z conf]# pwd 
    /develop/conf
    [root@izbp13xko46hud9vfr5s94z conf]# ls 
    docker-compose-zookeeper.yml
    [root@izbp13xko46hud9vfr5s94z conf]# COMPOSE_PROJECT_NAME=zookeeper_cluster docker-compose up
    -bash: docker-compose: 未找到命令
    [root@izbp13xko46hud9vfr5s94z conf]#

本例在执行过程中，遇到了`-bash: docker-compose: 未找到命令`的错误，解决方案是下载`docker-compose`并安装即可。  
安装命令：

curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
    chmod +x /usr/local/bin/docker-compose

安装完成后，重新执行`docker-compose up -d`这个命令，结果如下：

[root@izbp13xko46hud9vfr5s94z conf]# docker-compose up -d 
    Starting zoo1 ... done
    Starting zoo2 ... done
    Starting zoo3 ... done
    [root@izbp13xko46hud9vfr5s94z conf]#

### 查看zookeeper集群实例 ###

*  通过`docker ps`查看

[root@izbp13xko46hud9vfr5s94z ~]# docker ps 
    CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                                        NAMES
    e53b4c838001        zookeeper           "/docker-entrypoint.…"   4 minutes ago       Up 44 seconds       2888/tcp, 0.0.0.0:2181->2181/tcp, 3888/tcp   zoo1
    19282fb6f9b4        zookeeper           "/docker-entrypoint.…"   4 minutes ago       Up 44 seconds       2888/tcp, 3888/tcp, 0.0.0.0:2182->2181/tcp   zoo2
    099b926fa2d3        zookeeper           "/docker-entrypoint.…"   4 minutes ago       Up 44 seconds       2888/tcp, 3888/tcp, 0.0.0.0:2183->2181/tcp   zoo3
    [root@izbp13xko46hud9vfr5s94z ~]#

*  通过`docker-compose ps`查看  
    这个命令需要在`docker-compose`配置文件下执行。

[root@izbp13xko46hud9vfr5s94z conf]# docker-compose ps 
    Name              Command               State                     Ports                   
    ------------------------------------------------------------------------------------------
    zoo1   /docker-entrypoint.sh zkSe ...   Up      0.0.0.0:2181->2181/tcp, 2888/tcp, 3888/tcp
    zoo2   /docker-entrypoint.sh zkSe ...   Up      0.0.0.0:2182->2181/tcp, 2888/tcp, 3888/tcp
    zoo3   /docker-entrypoint.sh zkSe ...   Up      0.0.0.0:2183->2181/tcp, 2888/tcp, 3888/tcp
    [root@izbp13xko46hud9vfr5s94z conf]#

### 停止、启动、重启docker-compose服务 ###

示例：

[root@izbp13xko46hud9vfr5s94z conf]# docker-compose stop
    Stopping zoo1 ... done
    Stopping zoo2 ... done
    Stopping zoo3 ... done
    [root@izbp13xko46hud9vfr5s94z conf]# docker-compose start 
    Starting zoo1 ... done
    Starting zoo2 ... done
    Starting zoo3 ... done
    [root@izbp13xko46hud9vfr5s94z conf]# docker-compose restart
    Restarting zoo1 ... done
    Restarting zoo2 ... done
    Restarting zoo3 ... done
    [root@izbp13xko46hud9vfr5s94z conf]#

### 如何查看zookeeper集群节点主从关系 ###

使用`docker exec -it zoo1 /bin/bash`这个命令进入`zoo1`节点中，之后输入`./bin/zkServer.sh statu`来查看节点主从关系  
示例：

[root@izbp13xko46hud9vfr5s94z conf]# docker exec -it zoo1 /bin/bash 
    bash-4.4# ./bin/zkServer.sh status
    ZooKeeper JMX enabled by default
    Using config: /conf/zoo.cfg
    Mode: follower
    bash-4.4#
