分享Memcached shell启动停止脚本

 注意：要使用这个shell，必须先成功建立memcache环境
1》建立memcached文件和权限
[[email protected] ~]# touch /etc/init.d/memcached
[[email protected] ~]# chmod +x /etc/init.d/memcached
2》编写Memcached shell管理脚本  vi  /etc/init.d/memcached
#!/bin/bash
# memcached  - This shell script takes care of starting and stopping memcached.
#
# chkconfig: - 90 10
# description: Memcache provides fast memory based storage.
# processname: memcached

memcached_path="/usr/local/bin/memcached"
memcached_pid="/var/run/memcached.pid"
memcached_memory="1024"

# Source function library.
. /etc/rc.d/init.d/functions

[ -x $memcached_path ] || exit 0

RETVAL=0
prog="memcached"

# Start daemons.
start() {
    if [ -e $memcached_pid -a ! -z $memcached_pid ];then
        echo $prog" already running...."
        exit 1
    fi

    echo -n $"Starting $prog "
    # Single instance for all caches
    $memcached_path -m $memcached_memory -l 0.0.0.0 -p 11211 -u root -d -P $memcached_pid
    RETVAL=$?

[ $RETVAL -eq 0 ] && {
        touch /var/lock/subsys/$prog
        success $"$prog"
    }
    echo
    return $RETVAL
}

# Stop daemons.
stop() {
    echo -n $"Stopping $prog "
    killproc -d 10 $memcached_path
    echo
    [ $RETVAL = 0 ] && rm -f $memcached_pid /var/lock/subsys/$prog

    RETVAL=$?

return $RETVAL
}

# See how we were called.
case "$1" in
        start)
            start
            ;;
        stop)
            stop
            ;;
        status)
            status $prog
            RETVAL=$?

;;
        restart)
            stop
            start
            ;;
        *)
            echo $"Usage: $0 {start|stop|status|restart}"
            exit 1
esac
exit $RETVAL
##############本脚本中的以下二个配置可依据实际而配置############
#memcached_path="/usr/local/bin/memcached"
#memcached_memory="1024"

3》 追究该脚本为系统服务
chkconfig --add memcached
chkconfig memcached on

4》測试（试试手啊）

<p>service memcached start|stop|status|restart </p>
