CentOS下redis自启动shell脚本

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

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

脚本源码：

#!/bin/bash
#
# redis - this script starts and stops the redis-server daemon
#
# chkconfig:  - 80 12
# description: redis is a persistent key-value database
# processname: redis-server
# config:   /usr/local/redis/etc/redis.conf
# pidfile:   /usr/local/redis/var/redis.pid

source /etc/init.d/functions

bin="/usr/local/redis/bin"
config="/usr/local/redis/etc/redis.conf"
pidfile="/usr/local/redis/var/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

注意：请将脚本中redis的启动文件、配置文件和pid文件存放位置按你配置的位置做相应修改，文件保存的时候注意是unix下可运行的模式，否则在linux下运行的时候会提示错误，/bin/bash^m: bad interpreter: no such file or directory
