将Redis设置为开机后台启动

今天周一，一大早来公司，就听到开发的同学说本地项目起不来了, 上周六加班儿还好好的, 应该是周日断电导致的.

redis是关闭的，redis没有设置开机自启动，于是就先把问题先解决吧，然后写个脚本设置redis开机自启动。

1、在写脚本前设置下redis允许在后台启动，修改redis.conf文件，把daemonize no改成daemonize yes

2、开始编写脚本

#vim /etc/init.d/redis  --创建脚本文件

REDISPORT=6379
EXEC=/usr/local/software/redis-4.0.9/redis-server
CLIEXEC=/usr/local/software/redis-4.0.9/redis-cli

PIDFILE=/data/redis-data/redis-6379/redis.pid
CONF="/data/redis-data/redis-6379/conf/redis.conf"

这里我的redis安装路径是/usr/local/software/redis-4.0.9,端口为6379,然后redis.conf文件在/data/***/conf/redis.conf下面，你们根据自己的实际情况修改就行(这个脚本可以根据redis自带的启动脚本进行修改，它默认的路径是在$redis/utils/redis_init_script，$redis是redis的安装路径)

 1 #!/bin/sh
 2 #chkconfig: 2345 80 05
 3 #description: Start and Stop redis

 5 REDISPORT=6379
 6 EXEC=/usr/local/software/redis-4.0.9/redis-server
 7 CLIEXEC=/usr/local/software/redis-4.0.9/redis-cli
 8
 9 PIDFILE=/data/redis-data/redis-6379/redis.pid
10 CONF="/data/redis-data/redis-6379/conf/redis.conf"
11
12 case "$1" in
13     start)
14         if [ -f $PIDFILE ];then
15             echo "$PIDFILE exists,process is already running or crashed"
16         else
17             echo "Starting Redis server..."
18             $EXEC $CONF
19         fi
20         ;;
21     stop)
22         if [ ! -f $PIDFILE ];then
23             echo "$PIDFILE does not exist,process is not running"
24         else
25             PID=$(cat $PIDFILE)
26             echo "Stopping..."
27             $CLIEXEC -p $REDISPORT shutdown
28             while [ -x /proc/${PID} ]
29                 do
30                     echo "Waiting for Redis to shutdown..."
31                     sleep 1
32                 done
33                 echo "Redis stopped"
34         fi
35         ;;
36     restart)
37         "$0" stop
38         sleep 3
39         "$0" start
40         ;;
41     *)
42         echo "Please use start or stop or restart as first argument"
43         ;;
44 esac

3、写完记得修改文件权限

#chmod +x /etc/init.d/redis

4、把脚本添加到系统服务列表

#chkconfig --add redis
#chkconfig redis
#chkconfig --list
#chkconfig --help // 这里如果上传的redis启动文件有问题, 可以通过help命令具体操作;
