Redis 在Centos Linux 上的启动脚本

Redis管理脚本基于Ubuntu 的发行版上的,Ubuntu的可以看这篇文章ubuntu安装启动redis,在Centos linux 上并不能用,下面的脚本可以用于CentOS:

用这个脚本管理之前,需要先配置下面的内核参数,否则Redis脚本在重启或停止redis时,将会报错,并且不能自动在停止服务前同步数据到磁盘上:

# vi /etc/sysctl.conf

vm.overcommit_memory = 1

然后应用生效:

# sysctl –p

建立redis启动脚本:

 

# vim /etc/init.d/redis

#!/bin/bash
#
# Init file for redis
#
# chkconfig: - 80 12
# description: redis daemon
#
# processname: redis
# config: /etc/redis.conf
# pidfile: /var/run/redis.pid
source /etc/init.d/functions
#BIN="/usr/local/bin"
BIN="/usr/local/bin"
CONFIG="/etc/redis.conf"
PIDFILE="/var/run/redis.pid"
### Read configuration
[ -r "$SYSCONFIG" ] && source "$SYSCONFIG"
RETVAL=0
prog="redis-server"
desc="Redis Server"
start() {
        if [ -e $PIDFILE ];then
             echo "$desc already running...."
             exit 1
        fi
        echo -n $"Starting $desc: "
        daemon $BIN/$prog $CONFIG
        RETVAL=$?
        echo
        [ $RETVAL -eq 0 ] && touch /var/lock/subsys/$prog
        return $RETVAL
}
stop() {
        echo -n $"Stop $desc: "
        killproc $prog
        RETVAL=$?
        echo
        [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/$prog $PIDFILE
        return $RETVAL
}
restart() {
        stop
        start
}
case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  restart)
        restart
        ;;
  condrestart)
        [ -e /var/lock/subsys/$prog ] && restart
        RETVAL=$?
        ;;
  status)
        status $prog
        RETVAL=$?
        ;;
   *)
        echo $"Usage: $0 {start|stop|restart|condrestart|status}"
        RETVAL=1
esac
exit $RETVAL

然后增加服务并开机自启动:

# chmod 755 /etc/init.d/redis
# chkconfig --add redis
# chkconfig --level 345 redis on
# chkconfig --list redis
