Centos 6.6(X64位)系统编译安装memcached 并安装PHP的memcache扩展

来源：互联网发布：泉州金蝶软件编辑：程序博客网时间：2024/05/19 06:17

第一步下载安装需要的包：

libevent-2.0.22-stable.tar.gz（http://libevent.org/）这个是memcache的支持包

memcached-1.4.24.tar（http://memcached.org/）

第二步：安装 libevent

   # tar zxvf libevent-2.0.22-stable.tar.gz       # cd libevent-2.0.22-stable               # mkdir  /usr/local/libevent       # ./configure --prefix=/usr/local/libevent/     # make && make instal

第三步：安装memcached

# tar zxvf memcached-1.4.24.tar.gz

# cd memcached-1.4.24

# mkdir

# ./configure --prefix=/usr/local/memcached/ --with-libevent=/usr/local/libevent/

# make && make install

第四步：设置memcached开机启动

   # vi /etc/rc.d/init.d/memcached

将以下内容写入

    #!/bin/sh    #    # memcached: MemCached Daemon    #    # chkconfig: - 90 25    # description: MemCached Daemon    #    # Source function library.    . /etc/rc.d/init.d/functions    . /etc/sysconfig/network    #[ ${NETWORKING} = "no" ] && exit 0    #[ -r /etc/sysconfig/dund ] || exit 0    #. /etc/sysconfig/dund    #[ -z "$DUNDARGS" ] && exit 0    start()    {    echo -n $"Starting memcached: "    daemon $MEMCACHED -u root-d -m 128 -l 127.0.0.100 -p 11211 -c 128 -P /tmp/memcached.pid    echo    }    stop()    {    echo -n $"Shutting down memcached: "    killproc memcached    echo    }    MEMCACHED="/usr/local/memcached/bin/memcached"    [ -f $MEMCACHED ] || exit 1    # See how we were called.    case "$1" in    start)    start    ;;    stop)    stop    ;;    restart)    stop    sleep 3    start    ;;    *)    echo $"Usage: $0 {start|stop|restart}"    exit 1    esac    exit 0

保存

最后，添加Memcached开机启动

# cd /etc/rc.d/init.d/

# chmod 777 memcached

# chkconfig --add memcached

# chkconfig --level 2345 memcached on

# service memcached start(启动)# service memcached stop(关闭)# service memcached restart(重启)

接下来是为PHP安装memcache扩展：

     # wget http://pecl.php.net/get/memcache-2.2.7.tgz

     # zxf memcache-2.2.7.tgz   # cd memcache-2.2.7   # /usr/local/php/bin/phpize   # ./configure --with-php-config=/usr/local/php/bin/php-config --enable-memcache   # make   # make install

显示 Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-zts-20131226/

最后将如下配置信息添加到php.ini文件中：

extension_dir = "/usr/local/php/lib/php/extensions/no-debug-zts-20131226/"
extension=memcache.so

备注：/usr/local/php/lib/php/extensions/no-debug-zts-20131226/这个路径可能会有不同，以您机器中的为准。

最后重启 httpd service httpd restart

查看phpinfo 会看到 memcache 扩展就说明安装成功

测试代码

<?php$memcache = new Memcache; //创建一个memcache对象    $memcache->connect('127.0.0.1', 11211) or die ("Could not connect"); //连接Memcached服务器    $memcache->set('key', 'test'); //设置一个变量到内存中，名称是key 值是test    $get_value = $memcache->get('key'); //从内存中取出key的值    echo $get_value;?>
