为php安装memcached扩展

发表于: lnmp | 作者: | 日期: 2018/5/03 07:05

https://pecl.php.net 上搜索memcached,能够找到两个memcached扩展:

memcache
主页:https://pecl.php.net/package/memcache
memcache已经很久没有更新了。

memcached
主页:https://pecl.php.net/package/memcached
php-memcached的github地址:https://github.com/php-memcached-dev/php-memcached
版本比较新,支持php7,使用了libmemcached库,推荐使用。

主页里有版本说明:

php-memcached 3.x:
支持的php版本: PHP 7.0 – 7.2;
libmemcached版本要求: libmemcached 1.x 或者更高;

php-memcached 2.x:
支持的php版本:PHP 5.2 – 5.6;
libmemcached版本要求:libmemcached 0.44 或者更高;

根据自己的php版本来选择合适的扩展版本。

memcached扩展的安装需要libmemcached,否则会报如下错误:

checking for libmemcached location… configure: error: memcached support requires libmemcached. Use –with-libmemcached-dir=

to specify the prefix where libmemcached headers and library are located

下载地址:https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz

安装libmemcached

wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz
tar -xzvf libmemcached-1.0.18.tar.gz
cd libmemcached-1.0.18
./configure
make
make install

完成之后会收到如下提示:


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

安装memcached扩展:

wget https://pecl.php.net/get/memcached-2.2.0.tgz
tar -xzvf memcached-2.2.0.tgz
cd memcached-2.2.0
/usr/local/php/bin/phpize
./configure –enable-memcache –with-php-config=/usr/local/php/bin/php-config
make
make install

如果需要开启sasl,configure如下:

./configure –enable-memcache –enable-memcached-sasl –with-php-config=/usr/local/php/bin/php-config

找到php.ini文件:

locate php.ini
/root/php-5.6.14/php.ini-development
/root/php-5.6.14/php.ini-production
cp /root/php-5.6.14/php.ini-production /usr/local/php/etc/php.ini

修改php.ini配置文件

vim /usr/local/php/etc/php.ini

添加如下内容:

extension = memcached.so

重启php-fpm:

service php-fpm restart

可以看到,memcached扩展已经安装成功:
