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. PORT=11211 if [ -f /etc/sysconfig/memcached ];then # Check that networking is up. RETVAL=0 start () { restart () { # See how we were called. 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
