php7 安装memcached扩展

1. 首先安装memcache的客户端库 libmemcached。

php版本不高于5.6可以安装
wget https://launchpad.net/libmemcached/1.0/1.0.17/+download/libmemcached-1.0.17.tar.gz
php7版本的1.0.17版本的libmemcache库安转不了会报错 只能装下面的1.0.18版本的
wget https://launchpadlibrarian.net/165454254/libmemcached-1.0.18.tar.gz

tar -zxvf libmemcached-1.0.18.tar.gz
cd libmemcached-1.0.18
./configure
make && make install
2.安装 php7 memcache扩展

git clone https://github.com/php-memcached-dev/php-memcached
git checkout -b php7
cd php_memcache
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make && make install

修改php.ini的配置
/usr/local/php7.1/lib/php.ini
加上：extension_dir="/usr/local/php7.1/lib/php/extensions/no-debug-non-zts-20160303/"(每个人的路径可能不一样)
extension = "memcached.so
重启php-fpm
