memcached安装配置
安装memcached需要libevent的支持,所以先安装libevent;
一、安装libevent
1.下载
cd /usr/local/src
wget https://cloud.github.com/downloads/libevent/libevent/libevent-2.0.20-stable.tar.gz
2.安装
# tar zxvf libevent-2.0.20-stable.tar.gz
# cd libevent-2.0.20-stable
# ./configure --prefix=/usr/local/libevent
# make && make install
libevent已经安装完成;
二、安装memcached
1.下载
# wget http://memcached.org/files/memcached-1.4.22.tar.gz
官网:http://memcached.org
2.安装
# cd /usr/local/src
# tar zxvf memcached-1.4.22.tar.gz
# cd memcached-1.4.22
# ./configure --prefix=/usr/local/memcached
//执行此上时会出现找不到libevent的路径,需要编辑configure(vi configure) 找到 trylibeventdir="" 更改为 trylibeventdir="/usr/local/libevent" 即可;
# make && make install
3.启动memcached
# /usr/local/memcached/bin/memcached -m 64m -p 11211 -d -u root -P /var/run/memcached.pid -c 256
* -m 最大内存大小,默认为64m;
* -p 使用tcp/ip端口,默认为11211;
* -d 作为守护进程在后台运行;
* -u 指定用户启动memcached程序;
* -P 设置保存memcached的pid文件的位置;
* -l 监听的服务器ip,如果有多个地址;
* -c 最大运行的并发连接数,默认为1024,要按照服务器的负载量来设定;
4.关闭memcached1
# kill `cat /var/run/memcached`
5.查看memcached的信息状态
#telnet ip(memcached服务器ip) 11211
输入:stats 即可查看到memcached的相关信息;
三、安装memcached的php扩展
1.下载
# wget http://pecl.php.net/get/memcache-3.0.5.tgz
# tar zxvf memcache-3.0.5.tgz
# cd memcache-3.0.5
# /usr/local/php/bin/phpize //生成configure文件
执行此命令如下:
Configuring for: PHP Api Version: 20121113 Zend Module Api No: 20121212 Zend Extension Api No: 220121212 Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable. Then, rerun this script. |
此信息提示需要安装autoconf,
# yum install -y autoconf
再次执行此命令:/usr/local/php/bin/phpize 如下显示即可:
Configuring for: PHP Api Version: 20121113 Zend Module Api No: 20121212 Zend Extension Api No: 220121212 |
2.安装
# ./configure --enable-memcache --with-php-config=/usr/local/php/bin/php-config
# make && make install
此步执行后会出现如下提示:
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/ |
修改php.ini文件
# vim /etc/php.ini
找到;extension_dir = "./" 修改为 extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/"
再在php.ini中添加如下一行代码:extension=memcache.so
退出保存即可。
至此已安装配置完成;
