Centos 7 Redis 安装并开机启动

一、下载并编译

cd /usr/local/bin
目录可以自己选，我将redis安装到/usr/local/bin目录下。
wget http://download.redis.io/releases/redis-5.0.5.tar.gz

tar xzf redis-5.0.5.tar.gz
cd redis-5.0.5
make

使用make命令之前，需要先安装gcc，如果在安装gcc之前执行了make命令，等安装gcc之后再执行make命令，会报“jemalloc/jemalloc.h: No such file or directory”错，此时需要执行“make distclean  && make”命令，这个命令会先清理上次编译的残留文件再执行编译。

完成第一步之后，redis-cli和redis-server这两个客户端和服务文件就放在redis-5.0.5/src下面，redis.conf文件在redis-5.0.5下面

二、配置开机启动脚本
vim /etc/init.d/redis

#!/bin/sh
    
# chkconfig: 2345 80 90
# description: Start and Stop redis
# PATH=/usr/local/bin:/sbin:/usr/bin:/bin
REDISPORT=6379　                      #端口
EXEC=/usr/local/bin/redis-5.0.5/src/redis-server    #redis-server路径  
REDIS_CLI=/usr/local/bin/redis-5.0.5/src/redis-cli  #redis_cli路径
PIDFILE=/var/run/redis_$REDISPORT.pid
CONF="/usr/local/bin/redis-5.0.5/redis.conf"    #redis.conf路径
AUTH="mypassword123"                  #密码信息

case "$1" in
    start)
        if [ -f $PIDFILE ]
        then
                echo "$PIDFILE exists, process is already running or crashed"
        else
                echo "Starting Redis server..."
                $EXEC $CONF
        fi
        if [ "$?"="0" ]
        then
              echo "Redis is running..."
        fi
        ;;
    stop)
        if [ ! -f $PIDFILE ]
        then
                echo "$PIDFILE does not exist, process is not running"
        else
                PID=$(cat $PIDFILE)
                echo "Stopping ..."
                
                if [ -z $AUTH ]
                then
                        $REDIS_CLI -p $REDISPORT SHUTDOWN
                else
                        $REDIS_CLI -a $AUTH -p $REDISPORT SHUTDOWN
                fi
                
                while [ -x ${PIDFILE} ]
               do
                    echo "Waiting for Redis to shutdown ..."
                    sleep 1
                done
                echo "Redis stopped"
        fi
        ;;
   restart|force-reload)
        ${0} stop
        ${0} start
        ;;
  *)
    echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2
        exit 1
esac

　　

开机启动脚本配置完成之后，使用以下命令赋予权限
chmod 755 /etc/init.d/redis
使用以下命令添加开机启动服务
systemctl enable redis
