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
