php添加mysqli扩展

任何php的扩展都可以在php的源码包内单独编译安装
此处因phpmyadmin需mysqli扩展,编译该模块安装,过程及一些问题记录如下:
php编译安装路径/usr/local/php
mysql编译安装路径/usr/local/mysql
进入php源码安装包的mysqli扩展路径下

cd /usr/local/php/ext/mysqli

生成configure文件,默认mysqli目录是没有configure文件的，执行了phpize后会生成文件configure

/usr/local/php/bin/phpize

编译安装

 ./configure --with-php-config=/usr/local/php/bin/php-config / --with-mysqli=/usr/local/mysql/bin/mysql_config

make && make install

Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/
Installing header files:        /usr/local/php/include/php/
查看so文件

ll /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/

-rwxr-xr-x 1 root root  738122 May 19 12:59 mysqli.so
-rwxr-xr-x 1 root root 1112744 Apr 25 12:34 opcache.a
-rwxr-xr-x 1 root root  589324 Apr 25 12:34 opcache.so

修改php.ini
在Dynamic Extensions注释下方添加即可

extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/mysqli.so

重启php
