Linux设置redis开机自启具体方法

1、设置redis.conf中daemonize为yes,确保守护进程开启。

2、编写开机自启动脚本

 vi /etc/init.d/redis
Copy after login

看清楚目录,是在 etc/init.d下新建redis文件 ,为什么,因为 linux开机会 执行这个目录中的文件

编写脚本,本人不会,但网上有人会,拿来就好

 # chkconfig: 2345 10 90  
 
 # description: Start and Stop redis  
 
   
 
 PATH=/usr/local/bin:/sbin:/usr/bin:/bin   #找到本机安装redis后,存放redis命令的目录  
 
 REDISPORT=6379                            #redis的默认端口, 要和下文中的redis.conf中一致
 
 EXEC=/usr/redisbin/redis-server           #redis服务端的命令
 
 REDIS_CLI=/usr/redisbin/redis-cli         #redis客户端的命令  这两个一般都在 PATH目录下
 
 PIDFILE=/var/run/redis.pid                #reids的进程文件生成的位置
 
 CONF="/usr/redisbin/redis.conf"           #redis的配置文件所在的目录
 
 #AUTH="1234"  这句没什么用可以不要  
 
 
 
 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 exists, process is not running."  
 
                 else  
 
                         PID=$(cat $PIDFILE)  
 
                         echo "Stopping..."  
 
                        $REDIS_CLI -p $REDISPORT  SHUTDOWN    
 
                         sleep 2  
 
                        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
Copy after login

编写完成,保存

修改文件的权限为 可执行的  chmod 775 /etc/init.d/redis

测试一下redis 的启动

/etc/init.d/redis start

启动成功

设置自动启动

chkconfig redis on

此时就会自动启动了,系统会给你一些提示,创建了  XXX.service文件

如下图

How to set redis to start automatically at boot under Linux

这里要说一下 usr/lib/systemd/system/ 这个目录

刚开始我一直不知道 我的nginx mysql php 是怎么开机自动启动的 后来我进入了这个目录看了,才知道,原来它们都在这里,网上说这里linux centos 新的启动方式,我不怎么了解,但是我知道了,这里的 文件都是可以开机自启的服务

所以我们要想知道 本机开机都自启了什么服务 可以来这个文件夹下看一下。
