Linux上设置memcached自启动

以下这段脚本：

#! /bin/sh
#
# chkconfig: - 55 45
# description:  The memcached daemon is a network memory cache service.
# processname: memcached
# config: /etc/sysconfig/memcached
# Source function library - for other linux
#. /etc/rc.d/init.d/functions
# Source function library - for suse linux
. /lib/lsb/init-functions
PORT=11211
USER=root
#最大连接数，根据实际需求修改
MAXCONN=1024
#最大内存量，单位M
CACHESIZE=128
OPTIONS=""

if [ -f /etc/sysconfig/memcached ];then
    . /etc/sysconfig/memcached
fi
# Check that networking is up.
if [ "$NETWORKING" = "no" ]
then
    exit 0
fi

RETVAL=0
prog="memcached"
start () {
    echo -n $"Starting $prog: "
    # insure that /usr/local/memcached has proper permissions
    chown $USER /usr/local/memcached
    /usr/local/memcached/bin/memcached -d -p $PORT -u $USER  -m $CACHESIZE -c $MAXCONN -P /usr/local/memcached/memcached.pid $OPTIONS
    RETVAL=$?
    echo
    [ $RETVAL -eq 0 ] && touch /var/lock/subsys/memcached
}
stop () {
    echo -n $"Stopping $prog: "
    killproc memcached
    RETVAL=$?
    echo
    if [ $RETVAL -eq 0 ] ; then
        rm -f /var/lock/subsys/memcached
        rm -f /usr/local/memcached/memcached.pid
    fi
}
restart () {
    stop
    start
}

# See how we were called.
case "$1" in
    start)
        start
        ;;
    stop)
    stop
    ;;
    status)
    status memcached
    ;;
    restart|reload)
    restart
    ;;
    condrestart)
    [ -f /var/lock/subsys/memcached ] && restart || :
    ;;
    *)
    echo $"Usage: $0 {start|stop|status|restart|reload|condrestart}"
    exit 1
esac
exit $?

　将以上这段中的内容的中文部分去掉即可，只是用来在代码中做注释。memcached的位置改成您自己的对应位置

将这段代码编辑在 /etc/init.d/memcached文件里面

然后执行脚本：

#  chmod 755 /etc/init.d/memcached
#  chkconfig --add memcached
#  chkconfig memcached on
#  service memcached start

以上如成功则重启下系统后查看下memcached是否已随系统启动
