centos 7设置redis开机自启

Linux设置redis开机自启

• 查询redis.conf配置文件的路径

  find / -name redis.conf
  

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

• 当Redis以守护进程方式运行时，Redis默认会把pid写入/var/run/redis.pid文件，查看配置文件的默认路径（记住这个路径，一会要用）。
  

• 编写开机自启动脚本

  vi /etc/init.d/redis
  

• 脚本内容如下：

  #!/bin/bash
  # chkconfig:   2345 90 10
  # description:  Redis is a persistent key-value database
  PATH=/usr/local/bin:/sbin:/usr/bin:/bin
  REDISPORT=6379
  # 如果不知道redis-server，redis-cli命令在哪里，通过find / -name redis-server/redis-cli 查找
  EXEC=/usr/local/bin/redis-server
  REDIS_CLI=/usr/local/bin/redis-cli
  PIDFILE=/var/run/redis_6379.pid
  CONF="/opt/redis-6.0.8/redis.conf"
  AUTH="123456"
  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
  
  

• 启动redis服务，测试

  /etc/init.d/redis start
  

• 启动成功会提示如下信息：

  Starting Redis server...
  Redis is running...
  

• 设置开机自启动

  chkconfig redis on
  

• 关机重启

  reboot
  

• 查看redis服务，有没有自启动

  ps -ef|grep redis
  

• 看到redis-server*:6379这个服务，就代表成功了。
