1,从本文附件中下载,上传到linux系统上
2,安装libevent:
# tar -zxvf libevent-1.2.tar.gz
# cd libevent-1.2
# ./configure –prefix=/usr
# make
# make install
测试libevent是否安装成功:
# ls -al /usr/lib | grep libevent
lrwxrwxrwx 1 root root 21 11?? 12 17:38 libevent-1.2.so.1 -> libevent-1.2.so.1.0.3
-rwxr-xr-x 1 root root 263546 11?? 12 17:38 libevent-1.2.so.1.0.3
-rw-r–r– 1 root root 454156 11?? 12 17:38 libevent.a
-rwxr-xr-x 1 root root 811 11?? 12 17:38 libevent.la
lrwxrwxrwx 1 root root 21 11?? 12 17:38 libevent.so -> libevent-1.2.so.1.0.3
还不错,都安装上了

3,安装memcache
# tar zxvf memcached-1.2.0.tar.gz
# cd memcached-1.2.0
# ./configure –with-libevent=/usr
# make
?
测试是否成功安装memcached:
# ls -al /usr/local/bin/mem*
-rwxr-xr-x 1 root root 137986 11?? 12 17:39 /usr/local/bin/memcached
-rwxr-xr-x 1 root root 140179 11?? 12 17:39 /usr/local/bin/memcached-debug
?
4,启动Memcache的服务器端:
# /usr/local/bin/memcached -d -m 10 -u root -l 192.168.141.64 -p 12000 -c 256 -P /tmp/memcached.pid
?
-d选项是启动一个守护进程,
-m是分配给Memcache使用的内存数量,单位是MB,我这里是10MB,
-u是运行Memcache的用户,我这里是root,
-l是监听的服务器IP地址,如果有多个地址的话,我这里指定了服务器的IP地址192.168.0.200,
-p是设置Memcache监听的端口,我这里设置了12000,最好是1024以上的端口,
-c选项是最大运行的并发连接数,默认是1024,我这里设置了256,按照你服务器的负载量来设定,
-P是设置保存Memcache的pid文件,我这里是保存在 /tmp/memcached.pid
?
结束Memcache进程,执行:
?
# kill `cat /tmp/memcached.pid`
?
如果启动Memcached服务的时候遇到了
/usr/local/bin/memcached: error while loading shared libraries: libevent-1.2.so.1: cannot open shared object file: No such file or directory;
解决方案:
#ln -s /usr/lib/libevent-1.3.so.1 /usr/lib64/libevent-1.3.so.1
#/usr/local/bin/memcached -d -m 100 -u root -p 12000 -c 1000 -P /tmp/memcached.pid
#ps -aux |grep 'memcached'
