Linux下Memcached的安装步骤

此文章转载自http://blog.csdn.net/fengyily/article/details/35569433(经测试正确)

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、下载安装最新版本:http://memcached.org/downloads
# wget http://memcached.org/files/memcached-1.4.20.tar.gz

#tar zxvf memcached-1.4.20.tar.gz

# cd memcached-1.4.20

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


四、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

五、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...
Connected to 127.0.0.1.
Escape character is ‘^]‘.(退出telnet的方法是:quit+回车)
