1.分别把memcached和libevent下载回来,放到 /tmp 目录下:安装Memcache的PHP扩展
# cd /tmp
# wget http://www.danga.com/memcached/dist/memcached-1.2.0.tar.gz
# wget http://www.monkey.org/~provos/libevent-1.2.tar.gz
2.先安装libevent:
# tar zxvf libevent-1.2.tar.gz
# cd libevent-1.2
# ./configure –prefix=/usr
# make
# make install
3.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。
4.安装memcached,同时需要安装中指定libevent的安装位置:
# cd /tmp
# tar zxvf memcached-1.2.0.tar.gz
# cd memcached-1.2.0
# ./configure –with-libevent=/usr
# make
# make install
如果中间出现报错,请仔细检查错误信息,按照错误信息来配置或者增加相应的库或者路径。
安装完成后会把memcached放到 /usr/local/bin/memcached ,
5.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
tar vxzf memcache-2.2.1.tgz3.上述安装完后会有类似这样的提示:
cd memcache-2.2.1
/usr/local/php/bin/phpize
./configure –enable-memcache –with-php-config=/usr/local/php/bin/php-config –with-zlib-dir
make
make install
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-2007xxxx/4.把php.ini中的extension_dir = “./”修改为
extension_dir = “/usr/local/php/lib/php/extensions/no-debug-non-zts-2007xxxx/”5.添加一行来载入memcache扩展:extension=memcache.so
-d选项是启动一个守护进程,2.如果要结束Memcache进程,执行:
-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,
# kill `cat /tmp/memcached.pid`也可以启动多个守护进程,不过端口不能重复。
