启动脚本

单实例设置自启动脚本

1、复制redis启动脚本

redis启动脚本一般在redis根目录的utils,如果不知道路径,可以先查看路径

[root@slj-redis data1]#  find / -name redis_init_script

/data1/redis-cluster/redis-4.0.9/utils/redis_init_script

复制启动脚本到/etc/init.d/redis文件中

cp /data1/redis-cluster/redis-4.0.9/utils/redis_init_script /etc/init.d/redis-alone

2、更改redis-alone脚本

首先添加如下俩行

# chkconfig: 2345 90 10

# description: Redis is a persistent key-value database

其次更改EXEC   CLIEXEC  CONF 为实际所安装目录即可

REDISPORT=6379

EXEC=/data1/redis-alone/bin/redis-server

CLIEXEC=/data1/redis-alone/bin/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid

CONF="/data1/redis-alone/redis.conf"

chkconfig redis-alone on

集群设置自启动

先写好集群启动脚本

[root@slj-redis redis-cluster]# cat all-start.sh

cd /data1/redis-cluster/redis- 

./redis-server redis.conf 

cd /data1/redis-cluster/redis-

./redis-server redis.conf

cd /data1/redis-cluster/redis-

./redis-server redis.conf

cd /data1/redis-cluster/redis-

./redis-server redis.conf

cd /data1/redis-cluster/redis-

./redis-server redis.conf

cd /data1/redis-cluster/redis-

./redis-server redis.conf

关闭脚本

[root@slj-redis redis-cluster]# vim all-stop.sh

redis-cli -h   shutdown

redis-cli -h   shutdown

redis-cli -h   shutdown

redis-cli -h   shutdown

redis-cli -h   shutdown

redis-cli -h   shutdown

[root@slj-redis init.d]# vim redis-cluster

#!/bin/sh

#

# chkconfig:   

# description: Redis-cluster autostart

. /etc/init.d/functions

case "$1" in

    start)

        /bin/bash /data1/redis-cluster/all-start.sh

        ;;

    stop)

        /bin/bash /data1/redis-cluster/all-stop.sh

        ;;

    *)

        echo "Usage: $0 (start|stop)"

        ;;

esac

chkconfig redis-cluster on
