# 解壓縮
unzip NON_BLOCKING_IO_php7.zip
# 進入解壓後的目錄
cd pecl-memcache-NON_BLOCKING_IO_php7/
# 生成配置文件
/usr/local/php/bin/phpize
# 配置
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install
# 在 php.ini 中添加擴展
extension=memcache
# 重啓服務
# 能夠使用下面三種方式中的一種(具體看php的安裝方式)
service php-fpm restart
kill -USR2 `cat  /usr/local/php/var/run/php-fpm.pid`
systemctl reload php-fpm
