memcached安装和验证

1》 libevent安装 官网down: http://www.monkey.org 我的网盘down：http://pan.baidu.com/s/1qW8syZi [root@luozhonghua memcachedsource]# tar -zxvf libevent-1.4.13-stable.tar.gz [root@luozhonghua memcachedsource]# cd libevent-1.4.13-stable [root@

1》 libevent安装

官网down: http://www.monkey.org

我的网盘down：http://pan.baidu.com/s/1qW8syZi

[root@luozhonghua memcachedsource]# tar -zxvf libevent-1.4.13-stable.tar.gz

[root@luozhonghua memcachedsource]# cd libevent-1.4.13-stable

[root@luozhonghua memcachedsource]# ./configure --prefix=/usr

[root@luozhonghua memcachedsource]# make && make install

#./configure --prefix=/usr && make && make install

这里一定要注意指定--prefix，后面配置memcached的时候就有必要用到。

2》 memcached安装

官网down: http://www.monkey.org

我的网盘down：http://pan.baidu.com/s/1qW8syZi

[root@luozhonghua memcachedsource]# tar -zxvf memcached-1.4.5.tar.gz

[root@luozhonghua memcachedsource]# cd memcached-1.4.5

[root@luozhonghua memcached-1.4.5]# ./configure --with-libevent=/usr/lib

[root@luozhonghua memcached-1.4.5]# make && make install

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

这里一定要指定libevent的路径，否则启动的时候就有找不到libevent的so文件的错误！

3> memcached 启动

# /usr/local/bin/memcached -m 32m -p 11211 -d -u root -P /var/run/memcached.pid -c 256 -vv

/usr/local/bin/memcached -d -m 512 -p 11211 -u root -c 256 -P /var/run/memcached.pid

4> memcached 关闭

kill -9 `cat /var/run/memcached.pid`

注意，如果`cat /var/run/memcached.pid`值是缓存上一次的就无效，可直接查到pid值=7787
