• Linux系统下Memcached的安装以及自启动


    一、准备工作:

        1.下载libevent:http://monkey.org/~provos/libevent/ (由于memcached与客户端的通信是借助libevent来实现的,所以此动作必须在memcached安装前完成)

        2.下载memcached:http://memcached.org/ (注意:memcache是由服务器端和客户端共同组成,此处指memcache的服务器端,客户端在memcache的官网也提供了下载地址)

    二、libevent安装:

        1.解压libevent安装包:
        shell > tar zxvf libevent-2.0.10-stable.tar.gz

        2.进入解压后的目录并执行如下命令:

        shell > ./configure (或./configure --prefix=libevent安装目录,默认安装目录为/usr/local/lib)

        shell > make && make install

        3.查看安装是否成功

        测试libevent是否安装成功:ls -al /usr/lib | grep libevent(或 ls -al /usr/local/lib | grep libevent)
        

        4.Now we need to update /etc/ld.so.conf.d/libevent-i386.conf to add the path information for libevent. Use your favorite editor to edit /etc/ld.so.conf.d/libevent-i386.conf and add the following line if it doesn’t exist:

    /usr/local/lib/,and then run ldconflg

        注意:向libevent-i386.conf中添加的是libevent库的安装目录(如:/usr/local/lib);ldconfig是一个动态链接库管理命令

    三、Memcached安装:

        1.解压memcached安装目录:

        shell > tar zxvf memcached-1.4.5.tar.gz

        2.进入解压后的目录并执行如下命令:
        shell > ./configure (或./configure --with-libevent=libevent安装目录 --prefix=memcached安装目录,默认安装在/usr/local/bin目录下)

        shell > make && make install

        3.测试memcached安装是否成功:

        shell > memcached -u root -vv后出现如下画面则说明成功:
       

    四、配置memcached自启动

        1.编写memcached自启动脚本或直接使用memcached安装包中的脚本(位置如下,本文使用官方自带的脚本)
       

        2.修改自启动脚本(红色部分标识)

    #! /bin/sh
    #
    # chkconfig: - 55 45
    # description:  The memcached daemon is a network memory cache service.
    # processname: memcached
    # config: /etc/sysconfig/memcached

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

    PORT=11211
    USER=root
    MAXCONN=1024
    CACHESIZE=64
    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

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

        3.将此脚本呢cp到/etc/init.d目录下并改名为memcached,然后执行chmod a+x memcached,如下:

        shell > cp memcached.sysv /etc/init.d/memcached

        shell > chmod 755 /etc/init.d/memcached

        4.将memcached加入系统服务:

        shell > chkconfig --add memcached

        shell > chkconfig memcached on

        5.以服务方式运行memcached
        shell > 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
