memcached安装与验证
1）、libevent安装
官网down: http://www.monkey.org
我的网盘down：http://pan.baidu.com/s/1qW8syZi
复制代码 代码示例:
[root@jbxue memcachedsource]# tar -zxvf libevent-1.4.13-stable.tar.gz
[root@jbxue memcachedsource]# cd libevent-1.4.13-stable
[root@jbxue memcachedsource]# ./configure --prefix=/usr
[root@jbxue memcachedsource]# make && make install
#./configure --prefix=/usr && make && make install
注意，务必指定--prefix，后面配置memcached时就有必要用到。
2）、memcached安装
官网down: http://www.monkey.org
我的网盘down：http://pan.baidu.com/s/1qW8syZi
复制代码 代码示例:
[root@jbxue memcachedsource]# tar -zxvf memcached-1.4.5.tar.gz
[root@jbxue memcachedsource]# cd memcached-1.4.5
[root@jbxue memcached-1.4.5]# ./configure --with-libevent=/usr/lib
[root@jbxue memcached-1.4.5]# make && make install
# ./configure --with-libevent=/usr/lib && make && make install
注意，此处一定要指定libevent的路径，否则启动时会出现找不到libevent的so文件的错误。
3）、memcached 启动
复制代码 代码示例:
# /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
复制代码 代码示例:
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。
