php7 怎麼安裝mysqli?

centos php7 安裝mysqli擴展心得

在新配服務器時發現，php無法連接到mysql。通過phpinfo發現。根本沒有顯示mysqli的相關配置。經過一系列研究。總結了下。：

第一步：

在phpinfo裏沒有mysqli配置，原因是安裝php7時沒有configure mysqli

安裝php方法：wget http://cn2.php.net/distributions/php-7.1.5.tar.gz

tar zxvf php-7.1.5.tar.gzcd php-7.1.5./configure --with-php-config=/usr/local/php/bin/php-config --with-mysqli=/usr/bin/mysql_config             注：/usr/bin/mysql_config   這個路徑爲自己的mysql_config路徑   可通過 find -name mysql_config查找make && make install　　　　　　　　cp  php.ini-development /usr/local/lib/php.inicp sapi/fpm/init.d.php-fpm /etc/init.d/php7-fpmchmod +x /etc/init.d/php7-fpmcd /usr/local/php/etccp php-fpm.conf.default php-fpm.confcp php-fpm.d/www.conf.default php-fpm.d/www.conf/etc/init.d/php7-fpm  start 啓動php

安裝完之後會發現phpinfo有mysqli了

第二步：安裝mysqli擴展

方法：

cd /usr/local/php-7.1.5/ext/mysqli   //到php文件ext下的mysqli/usr/local/php/bin/phpize./configure --with-php-config=/usr/local/php/bin/php-config --with-mysqli=/usr/bin/mysql_config

注：usr/bin/mysql_config 路徑同第一步方法

現在應該已經有mysqli擴展了

第三步：

修改php.ini

通過phpinfo 查找到php.ini的路徑。修改php.ini。取消註釋php_mysqi.dll
