后续的运行步骤见`README.md`或[https://github.com/antirez/redis][https_github.com_antirez_redis]。  
可以看到，其中的`Makefile`和`src/`源代码目录

*  编译源代码 `make`

m -rf redis-server redis-sentinel redis-cli redis-benchmark redis-check-rdb redis-check-aof *.o *.gcda *.gcno *.gcov redis.info lcov-html Makefile.dep dict-benchmark
    make[1]: Leaving directory '/home/wuyujin/Downloads/redis-5.0.7/src'

    Hint: It's a good idea to run 'make test' ;) make[1]: Leaving directory '/home/wuyujin/Downloads/redis-5.0.7/src'
    wuyujin@ubuntu18:~/Downloads/redis-5.0.7$

*  测试`make test`  
    我第一次运行时，报错：`You need tcl 8.5 or newer in order to run the Redis test`，需要安装TCL。

wuyujin@ubuntu18:~/Downloads/redis-5.0.7$ sudo make test
    cd src && make test
    make[1]: Entering directory '/home/wuyujin/Downloads/redis-5.0.7/src'

    Makefile:6: recipe for target 'test' failed

    wuyujin@ubuntu18:~/Downloads/redis-5.0.7$

*  安装TCL  
    若下载链接失效，在[https://sourceforge.net/projects/tcl/][https_sourceforge.net_projects_tcl]获取最新链接即可。

wget https://nchc.dl.sourceforge.net/project/tcl/Tcl/8.6.10/tcl8.6.10-src.tar.gz
    sudo tar xzvf tcl8.6.1-src.tar.gz  -C /usr/local/
    cd /usr/local/tcl8.6.10/unix/
    sudo ./configure
    sudo make
    sudo make install

*  重新运行`make test`

wuyujin@ubuntu18:~/Downloads/redis-5.0.7$ sudo make test
    [sudo] password for wuyujin: 
    cd src && make test
    make[1]: Entering directory '/home/wuyujin/Downloads/redis-5.0.7/src'

测试无误！

redis要用到的可执行文件已经生成了(在`./src/`下)  
如：`redis-server, redis-cli`等。

配置文件在redis根目录下

wuyujin@ubuntu18:~/Downloads/redis-5.0.7$ ll | grep conf
    -rw-r--r--  1 wuyujin wuyujin  61797 11月 20 01:05 redis.conf
    -rw-r--r--  1 wuyujin wuyujin   9710 11月 20 01:05 sentinel.conf
    wuyujin@ubuntu18:~/Downloads/redis-5.0.7$

*  移动文件夹 `sudo mv redis-5.0.7 /opt`  
    其实只需要移动其中有用的部分文件。但是太麻烦(我不清楚哪些文件一点用都没有)，所以移动整个文件。
 *  配置环境变量  
    编辑`/etc/profile`，添加以下配置：

# redis
    export REDIS_HOME=/opt/redis-5.0.7
    export PATH=${REDIS_HOME}/src:$PATH

重启，使最新配置对所有用户生效。

*  测试环境变量

echo $REDIS_HOME; echo $PATH
    redis-server --version

## 运行 && 配置 ##

*  启动服务器 `redis-server`

wuyujin@ubuntu18:~$ redis-server

以上，即为成功运行。  
也可以在启动时`指定要读取的配置文件`，并且追加配置文件中有的`参数对`。  
**NOTE**：redis服务器启动时默认读取的配置文件是`/path/to/redis.conf`，而不是我们redis根目录中的`redis.conf`。  
所以如果想要修改文件，要在启动redis服务器的时候指定读取该配置文件。

wuyujin@ubuntu18:~$ redis-server --help
    Usage: ./redis-server [/path/to/redis.conf] [options]
           ./redis-server - (read config from stdin)
           ./redis-server -v or --version
           ./redis-server -h or --help
           ./redis-server --test-memory <megabytes>
    
    Examples:
           ./redis-server (run the server with default conf)
           ./redis-server /etc/redis/6379.conf
           ./redis-server --port 7777
           ./redis-server --port 7777 --replicaof 127.0.0.1 8888
           ./redis-server /etc/myredis.conf --loglevel verbose
    
    Sentinel mode:
           ./redis-server /etc/sentinel.conf --sentinel
    wuyujin@ubuntu18:~$

*  客户端执行命令 `redis-cli -h IP地址 -p 端口号 -a 密码`  
    先简单测试一下：

wuyujin@ubuntu18:~$ redis-cli 
    127.0.0.1:6379> ping
    PONG
    127.0.0.1:6379> set name wuyujin1997
    OK
    127.0.0.1:6379> get name
    "wuyujin1997"
    127.0.0.1:6379> quit
    wuyujin@ubuntu18:~$

在运行`redis-server`的窗口按`Ctrl+C`结束程序。打印以下：

3637:M 08 Feb 2020 22:36:52.113 * Ready to accept connections
    ^C3637:signal-handler (1581172675) Received SIGINT scheduling shutdown...

    3637:M 08 Feb 2020 22:37:55.099 # Redis is now ready to exit, bye bye...
    wuyujin@ubuntu18:~$

*  后台运行`redis-server`及进程号查询、杀死进程

wuyujin@ubuntu18:~$ # 查询有没有redis-server运行
    wuyujin@ubuntu18:~$ ps -axu | grep redis-server
    wuyujin   3908  0.0  0.0  21532  1076 pts/0    S+   22:45   0:00 grep --color=auto redis-server
    wuyujin@ubuntu18:~$ 
    wuyujin@ubuntu18:~$ # 后台运行redis-server
    wuyujin@ubuntu18:~$ redis-server --daemonize yes

    wuyujin@ubuntu18:~$ kill -9 3938
    wuyujin@ubuntu18:~$

## redis密码和配置文件 ##

安全起见，推荐设置redis密码。  
两种，一种是单次配置：给正在运行的redis服务器设置密码(仅本次运行期间有效)，需要在`redis-server`运行期间使用`redis-cli`发送命令设置密码；  
另一种是固定配置，即每次redis服务器启动都有效，需要修改redis的配置文件`redis.conf`中的参数项`requirepass`。

*  固定配置：  
    修改配置文件`redis.conf`  
    其中有一段：

# Require clients to issue AUTH <PASSWORD> before processing any other
    # commands.  This might be useful in environments in which you do not trust
    # others with access to the host running redis-server.
    #
    # This should stay commented out for backward compatibility and because most
    # people do not need auth (e.g. they run their own servers).
    #
    # Warning: since Redis is pretty fast an outside user can try up to
    # 150k passwords per second against a good box. This means that you should
    # use a very strong password otherwise it will be very easy to break.
    #
    # requirepass foobared

将`# requirepass foobared`改为`requirepass test1234`(去掉注释符号，密码自定义，我的是test1234)。

启动服务器：`redis-server /opt/redis-5.0.7/redis.conf`  
登录客户端：

wuyujin@ubuntu18:~$ redis-cli -h 127.0.0.1 -p 6379 -a test1234
    Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
    127.0.0.1:6379> config get requirepass
    1) "requirepass"
    2) "test1234"
    127.0.0.1:6379> quit
    wuyujin@ubuntu18:~$

*  单次配置  
    `redis-server`每次运行会读取配置文件中的配置项，包括配置好的、固定的密码。  
    当`redis-server`运行之后，能不能修改密码呢？可以的。  
    登录客户端，修改密码后，退出重新登录一次客户端，发现要用刚才更新的密码。

wuyujin@ubuntu18:~$ redis-cli -h 127.0.0.1 -p 6379
    127.0.0.1:6379> config get requirepass
    (error) NOAUTH Authentication required.
    127.0.0.1:6379> auth test1234
    OK
    127.0.0.1:6379> config get requirepass
    1) "requirepass"
    2) "test1234"
    127.0.0.1:6379> config set requirepass abcde
    OK
    127.0.0.1:6379> config get requirepass
    1) "requirepass"
    2) "abcde"
    127.0.0.1:6379> quit
    wuyujin@ubuntu18:~$ redis-cli -h 127.0.0.1 -p 6379
    127.0.0.1:6379> config get requirepass
    (error) NOAUTH Authentication required.
    127.0.0.1:6379> auth test1234
    (error) ERR invalid password
    127.0.0.1:6379> auth abcde
    OK
    127.0.0.1:6379> quit
    wuyujin@ubuntu18:~$

但是，新密码`abcde`只在本次`redis-server`启动时有效。  
重启`redis-server`，密码将重置(至于重置为何值，取决于启动时指定要读取的配置文件)。

*  配置文件结构  
    配置项主要分几类：

include
    module
    networ
    genera
    snapshotting
    replicatio
    securit
    client
    memory managemen
    lazy freein
    append only mod
    lua scripting
    redis cluster
    cluster docker/nat support
    slow lo
    latency monito
    event notificatio
    advanced confi
    active defragmentatio

*  常用配置项

# IP地址
    bind 127.0.0.1
    # 端口
    port 6379
    # 密码
    # requirepass foobared
    # 是否以守护进程运行(后台运行)
    daemonize no

另有redis的两种持久化方案RDB及AOF的细节，也是在配置文件中进行参数设置。

## 使用包管理工具快速安装 ##

若机器能联网，直接使用包管理工具安装redis，方便快捷，自动配置环境变量。只不过安装好的文件会比较分散，也可以通过命令查找。

*  安装 `apt-get install redis-server redis-tools`
 *  卸载并清除配置文件 `apt-get remove redis-server redis-tools --purge`
 *  查询软件安装位置 `dpkg -L redis-server redis-tools`
