1、安装libevent
tar zxvf libevent-1.4.13-stable.tar.gz
cd libevent-1.4.13-stable
./configure --prefix=/usr/local
make
make install
2、安装memcached
tar zxvf memcached-1.4.21.tar.gz
cd memcached-1.4.21
./configure --prefix=/usr/local/memcached --with-libevent=/usr/local
make
make install
3、安装完成后的memcached在 /usr/local/memcached/bin/memcached
将libevent-1.2.so.1拷贝到任何一个列出的lib下,或者软链接到列出的lib下(很多情况下是/usr/lib下有该文件，需要把该文件拷贝到/usr/lib64/下)
ln -s /usr/local/lib/libevent-2.0.so.5 /lib64/libevent-2.0.so.5
4、启动MemCached，-m表示分配的内存 -c 最大链接数 默认是1024 -l可以设置成 0.0.0.0
/usr/local/memcached/bin/memcached -d -m 256 -u root -l 192.168.150.33 -p 11211 -c 30000 -P /var/run/memcached.pid
5、也可以将启动配置写在一个脚本中startMemcached.sh
/usr/local/memcached/bin/memcached -d -m 4000 -u cacheuser -l 192.168.150.33 -p 11211 -c 10240 -P /var/run/memcached.pid
/usr/local/memcached/bin/memcached -d -m 4000 -u cacheuser -l 192.168.150.33 -p 11212 -c 10240 -P /var/run/memcached.pid
/usr/local/memcached/bin/memcached -d -m 4000 -u cacheuser -l 192.168.150.33 -p 11213 -c 10240 -P /var/run/memcached.pid
