php7 怎么安装mysqli?

centos php7 安装mysqli扩展心得

在新配服务器时发现，php无法连接到mysql。通过phpinfo发现。根本没有显示mysqli的相关配置。经过一系列研究。总结了下。：

第一步：

在phpinfo里没有mysqli配置，原因是安装php7时没有configure mysqli

安装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   这个路径为自己的mysql_config路径   可通过 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 启动php

安装完之后会发现phpinfo有mysqli了

第二步：安装mysqli扩展

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 路径同第一步方法

现在应该已经有mysqli扩展了

第三步：

修改php.ini

通过phpinfo 查找到php.ini的路径。修改php.ini。取消注释php_mysqi.dll
