一、软件准备 memcached-1.4.13.tar.gz，下载地址：http://memcached.org/ libevent-2.0.19-stable.tar.gz，下载地址：http://libevent.org/ 二、具体安装 1、安装libevent [root@localhost tools]# tar zxvf libevent-2.0.19-stable.tar.gz [root@localhost tools]# cd libevent-2.0.19-stable [root@localhost libevent-2.0.19-stable]# ./configure --prefix=/usr [root@localhost libevent-2.0.19-stable]# make [root@localhost libevent-2.0.19-stable]# make install 2、memcached安装 [root@localhost tools]# tar zxvf memcached-1.4.13.tar.gz [root@localhost tools]# cd memcached-1.4.13/ [root@localhost memcached-1.4.13]# ./configure --prefix=/usr/local [root@localhost memcached-1.4.13]# make [root@localhost memcached-1.4.13]# make install 3、测试是否安装成功 [root@localhost memcached-1.4.13]# ls -la /usr/local/bin/mem* -rwxr-xr-x 1 root root 201441 Nov 8 15:10 /usr/local/bin/memcached [root@localhost memcached-1.4.13]# 4、将libevent安装的/usr/local/lib输出到引用库路径 # vi ~/.bash_profile 加入如下一行： export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib 5、启动memcache的服务器端 [root@localhost tools]# memcached -d -m 100 -l 192.168.11.193 -p 11211 -u root -c 256 -P /tmp/memcached.pid [root@localhost tools]# netstat -an|grep 11211 tcp 0 0 192.168.0.14:11211 0.0.0.0:* LISTEN udp 0 0 192.168.0.14:11211 0.0.0.0:* 启动选项说明： -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100MB， -u是运行memcache的用户，也可以使用adduser为memcahed专门创建一个用户 -l是监听的服务器IP地址，这里指定了服务器的IP地址192.168.11.193 -p是设置memcache监听的端口，我这里设置了11211，由于是默认端口，因此不指定-p参数也可 -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 6、结束memcache进程，执行： [root@localhost tools]# kill cat /tmp/memcached.pid 或者取出/tmp/memcached.pid文件里的进程号，然后kill -9 进程号 也可以启动多个守护进程，不过端口不能重复。 7、测试 另外打开一个终端，执行下面的命令 [root@localhost ~]# telnet 192.168.11.193 11211 Trying 192.168.11.193... Connected to 192.168.11.193 (192.168.11.193).
