Memcache介绍:danga.com的一个开源项目,它是一个高性能的分布式的内存对象缓存系统通过在内存里维护一个统一的巨大的Hash表,能够用来存储各种格式的数据
* 查看当前的memcache连接数
# netstat -n | grep :11211 | wc -l
* 查看默认允许的连接数,这里设置的11211端口默认连接数是40960
# cat /etc/rc.local
* 如何查看memcache服务器端版本
# ./memcached -h
* Linux下的Memcache安装
# cd /usr/local/src
装yum扩展源:# yum install -y epel-release
memcache模块:# yum install -y php-pecl-memcached
下载Memcache:# wget http://www.danga.com/memcached/dist/memcached-1.2.0.tar.gz
下载libevent:# wget http://www.monkey.org/~provos/libevent-1.2.tar.gz
先装libevent:# tar zxvf libevent-1.2.tar.gz
# cd libevent-1.2
# ./configure --prefix=/usr/local/libevent
# make
# make install
* 测试libevent是否安装成功
# ls -al /usr/local/libevent/lib | grep libevent
lrwxrwxrwx 1 root root 21 Apr 14 13:01 libevent-1.2.so.1 -> libevent-1.2.so.1.0.3
-rwxr-xr-x 1 root root 264056 Apr 14 13:01 libevent-1.2.so.1.0.3
-rw-r--r-- 1 root root 430388 Apr 14 13:01 libevent.a
-rwxr-xr-x 1 root root 820 Apr 14 13:01 libevent.la
lrwxrwxrwx 1 root root 21 Apr 14 13:01 libevent.so -> libevent-1.2.so.1.0.3
安装memcached # cd /usr/local/src
# yum install -y libevent-devel
# tar zxvf memcached-1.2.0.tar.gz
# cd memcached-1.2.0
# ./configure --with-libevent=/usr/local/memcached
# make
# make install
* 测试是否成功安装memcached
# ls -al /usr/local/bin/mem*
-rwxr-xr-x 1 root root 113084 Apr 14 13:23 /usr/local/bin/memcached
-rwxr-xr-x 1 root root 117439 Apr 14 13:23 /usr/local/bin/memcached-debug
* 安装Memcache的PHP扩展
1.在http://pecl.php.net/package/memcache,选择想要下载的memcache版本
2.安装PHP的memcache扩展
# tar zxvf memcache-2.2.1.tgz
# cd memcache-2.2.1
# /usr/local/php5.6/bin/phpize
运行这个命令就会生成一个脚本,然后编译扩展
# ./configure --enable-memcache --with-php-config=/usr/local/php5.6/bin/php-config --with-zlib-dir
# make
# make install
# vim /usr/local/php5.6/etc/php.ini
extension_dir = "/usr/local/php5.6/lib/php/extensions/no-debug-non-zts-20131226/"
extension=memcache.so
* memcached的基本设置
1)启动Memcache的服务器端
# /usr/local/bin/memcached -d -m 100 -u root -l 127.0.0.1 -p 12000 -c 300 -P /tmp/mem cached.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,
2)如果要结束Memcache进程,执行:
# kill `cat /tmp/memcached.pid`
3)重启apache,service httpd restart
4)Memcache环境测试
运行下面的php文件,如果有输出This is a test! 就表示环境搭建成功
# cd /var/www/html
# vim hjt.php
<?php
$mem = new Memcache;
$mem->connect("127.0.0.1", 11211);
$mem->set('key', 'This is a test!', 0, 60);
$val = $mem->get('key');
echo $val;
?>
