php7 How to install mysqli?

centos php7 Installation experience of mysqli extension

When I configured the new server, I found that php could not Connect to mysql. Discovered via phpinfo. The relevant configuration of mysqli is not displayed at all. After a series of studies. Summarized. ：

Step one:

There is no mysqli configuration in phpinfo because there is no configure mysqli when installing php7

Installation method of php: wget http://cn2.php .net/distributions/php-7.1.5.tar.gz

tar zxvf php-7.1.5.tar.gz
cd 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.ini
cp sapi/fpm/init.d.php-fpm /etc/init.d/php7-fpm
chmod +x /etc/init.d/php7-fpm
cd /usr/local/php/etc
cp php-fpm.conf.default php-fpm.conf
cp php-fpm.d/www.conf.default php-fpm.d/www.conf
/etc/init.d/php7-fpm  start 启动php

After installation, you will find that phpinfo has mysqli

Step 2: Install the mysqli extension

Method:

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

Note: usr/bin/mysql_config path is the same as the first step method

make
make test
make install

Now there should be a mysqli extension

The third step ：

Modify php.ini

Find the path to php.ini through phpinfo. Modify php.ini. Uncomment php_mysqi.dll

End!
