Linux下Memcached的安装步骤

一、安装gcc

# yum -y install gcc

二、安装libevent

# wget http://www.monkey.org/~provos/libevent-2.0.12-stable.tar.gz
# tar zxf libevent-2.0.12-stable.tar.gz

# cd libevent-2.0.12-stable

#./configure --prefix=/usr/local/lib

# make && make install

三、安装make

# yum -y install make

四、下载安装最新版本：http://memcached.org/downloads

# wget http://memcached.org/files/memcached-1.4.20.tar.gz
# cd memcached-1.4.20

#./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/lib && make && make install

五、配置启动

# vi /etc/rc.local

#!/bin/sh

#

# This script will be executed *after* all the other init scripts.

# You can put your own initialization stuff in here if you don't

# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local

/usr/sbin/ntpdate ntpupdate.tencentyun.com >/dev/null 2>&1 &

/usr/local/agenttools/agent/startagent.sh /usr/local/agenttools/agent /dev/null

#secu-tcs-agent bootstart, install at Tue Apr 29 17:21:38 CST 2014.

/usr/local/sa/agent/secu-tcs-agent-mon-safe.sh > /dev/null 2>&1

/usr/local/memcached/bin/memcached -p 12677 -U 0 -d -r -u root -m 2040 -c 1024 -t 4

保存后退出，手动启动服务

# /usr/local/memcached/bin/memcached -p 12677 -U 0 -d -r -u root -m 2040 -c 1024 -t 4

注：如果出现/usr/local/memcached/bin/memcached: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory异常在/etc/ld.so.conf中加入/usr/local/lib这一行，保存之后，再运行：/sbin/ldconfig –v更新一下配置即可。

# vi /etc/ld.so.conf

# /sbin/ldconfig -V

六、测试memcached

# telnet 127.0.0.1 12677

出现以下信息表示启动成功

Trying 127.0.0.1...
