在 CentOS7 下安装、配置 Redis 服务

1. 安装依赖

➜  yum install -y gcc gcc-c++ kernel-devel

2. 下载源码包

# 推荐在这个目录存放各个软件的源码
➜  cd /usr/local/src

# 下载指定版本
➜  wget http://download.redis.io/releases/redis-5.0.5.tar.gz

# 下载最新稳定版
➜  wget http://download.redis.io/redis-stable.tar.gz
# 查看源码具体版本
➜  cat redis-stable/src/version.h

3. 编译安装

➜  tar zxvf redis-5.0.5.tar.gz
➜  cd redis-5.0.5
➜  make

# 安装到指定目录下
➜  make PREFIX=/usr/local/redis install

# 拷贝默认配置文件到指定目录
➜  mkdir /usr/local/redis/etc/
➜  cp redis.conf /usr/local/redis/etc/

# 拷贝可执行程序到系统目录下
➜  cd /usr/local/redis/bin/
➜  cp redis-benchmark redis-cli redis-server /usr/bin/

# 配置环境变量
➜  echo 'export PATH="$PATH:/usr/local/redis/bin"' &gt;&gt; /etc/profile
➜  source /etc/profile

# 验证
➜  redis-cli -v
redis-cli 5.0.5

4. 修改默认配置文件

这里只是一些推荐的常用基本配置，详细的参见配置文件中对各个配置项的说明，或者参照这里 https://www.runoob.com/redis/redis-conf.html

➜  vi /usr/local/redis/etc/redis_6379.conf

# 开启守护进程（后台）方式运行
daemonize yes

# 进程文件
pidfile /var/run/redis_6379.pid

# 只允许指定主机连接，默认所有网络
bind 127.0.0.1

# 修改端口号，默认 6379
port 6379

# 客户端闲置多长时间（单位：s）关闭连接
# 默认 0 ，无限制
timeout 300

# 日志级别，默认 notice      
loglevel verbose

# 日志记录方式，默认为标准输出（stdout）
# 如果以守护进程运行，并且此处采用标准输出，则日志发送给 /dev/null
logfile stdout

# 设置连接密码
requirepass <密码>

5. 启动服务

基本启动方式

# 以默认配置启动
redis-server 

# 指定配置文件
redis-server /usr/local/redis/etc/redis.conf

# 查看更多使用参数
redis-server -h

使用脚本启动

➜  cd redis-5.0.5/utils
➜  cp redis_init_script /etc/init.d/
➜  mv /etc/init.d/redis_init_script /etc/init.d/redis_6379
➜  vim /etc/init.d/redis_6379

#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.

### BEGIN INIT INFO
# Provides:     redis_6379
# Default-Start:        2 3 4 5
# Default-Stop:         0 1 6
# Short-Description:    Redis data structure server
# Description:          Redis data structure server. See https://redis.io
### END INIT INFO

# 根据实际安装情况修改这里的端口号和路径

REDISPORT=6379
EXEC=/usr/local/redis/bin/redis-server
CLIEXEC=/usr/local/redis/bin/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/usr/local/redis/etc/redis_${REDISPORT}.conf"

case "$1" in
    start)
        if [ -f $PIDFILE ]
        then
                echo "$PIDFILE exists, process is already running or crashed"
        else
                echo "Starting Redis server..."
                $EXEC $CONF
        fi
        ;;
    stop)
        if [ ! -f $PIDFILE ]
        then
                echo "$PIDFILE does not exist, process is not running"
        else
                PID=$(cat $PIDFILE)
                echo "Stopping ..."
                $CLIEXEC -p $REDISPORT shutdown
                while [ -x /proc/${PID} ]
                do
                    echo "Waiting for Redis to shutdown ..."
                    sleep 1
                done
                echo "Redis stopped"
        fi
        ;;
    *)
        echo "Please use start or stop as first argument"
        ;;
esac

使用脚本启动服务测试

➜  ./redis_6379 start
Starting Redis server...
19261:C 08 Nov 2019 01:42:46.848 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
19261:C 08 Nov 2019 01:42:46.848 # Redis version=5.0.5, bits=64, commit=00000000, modified=0, pid=19261, just started
19261:C 08 Nov 2019 01:42:46.848 # Configuration loaded

# 检查是否启动成功
➜  ps -ef | grep redis
root     19262     1  0 01:42 ?        00:00:00 /usr/local/redis/bin/redis-server 127.0.0.1:6379
root     19267 19129  0 01:43 pts/0    00:00:00 grep --color=auto redis

# 客户端连接测试
➜  redis-cli
127.0.0.1:6379&gt; KEYS *
(empty list or set)
127.0.0.1:6379&gt; exit

# 停止服务
➜  ./redis_6379 stop
Stopping ...
Waiting for Redis to shutdown ...
Redis stopped
[root@cnetos7-localhost init.d]#

6. 加入开机自启动

# 使用 root 用户操作

# 添加到自启动列表
# 这里的 redis_6379 与 /etc/init.d/redis_6379 文件名保持一致
➜  chkconfig --add redis_6379

# 将 2 3 4 5 级别设置为自启动
➜  chkconfig --level 2345 redis_6379 on

# 重启检查自启动是否生效
➜  reboot

也可使用如下 CentOS7+ 命令统一进行管理：

# 查看服务状态
➜  systemctl status redis_6379
