[root@localhost init.d]# chmod +x php-fpm 
[root@localhost init.d]# chkconfig php-fpm on

[root@localhost init.d]# vim /etc/profile
export PATH=/usr/local/php7/bin:/usr/local/php7/sbin:$PATH
[root@localhost init.d]# php -v

[root@localhost init.d]# service php-fpm start


（5）配置php
[root@localhost local]# cd src/php-7.2.0/
[root@localhost php-7.2.0]# ls

（6）测试
[root@localhost www]# vim index.php

[root@localhost www]# vim mysql.php

（7）安装PHP-mysql链接模块
  
[root@localhost www]# cd /usr/local/src/php-7.2.0/
[root@localhost php-7.2.0]# cd ext/
[root@localhost ext]# cd mysqli/
[root@localhost mysqli]# /usr/local/php7/bin/phpize
[root@localhost mysqli]# ./configure \
>     --with-php-config=/usr/local/php7/bin/php-config \
>     --enable-embedded-mysqli=shared \
>     --enable-shared

[root@localhost mysqli]# echo $?
0
[root@localhost mysqli]# make
[root@localhost mysqli]# make install
[root@localhost mysqli]# echo $?

[root@localhost mysqli]# cd /usr/local/php7/lib/php/extensions/no-debug-zts-20170718
[root@localhost no-debug-zts-20170718]# ls

[root@localhost php]# cd /usr/local/src/php-7.2.0/ext/pdo

[root@localhost php]# cd /usr/local/src/php-7.2.0/ext/pdo_mysql/
[root@localhost pdo_mysql]# /usr/local/php7/bin/phpize

[root@localhost pdo_mysql]# ./configure \
>     --with-php-config=/usr/local/php7/bin/php-config \
>     --with-pdo-mysql=mysqlnd

[root@localhost pdo_mysql]# echo $?
0
[root@localhost pdo_mysql]# make
[root@localhost pdo_mysql]# echo $?
0
[root@localhost pdo_mysql]# make install


(8)添加模块：
[root@localhost php-7.2.0]# cp php.ini-production  /usr/local/php7/etc/php.ini
[root@localhost php-7.2.0]# cd /usr/local/php7/etc/

[root@localhost etc]# vim php.ini 
extension_dir = "/usr/local/php7/lib/php/extensions/no-debug-zts-20170718"
extension = mysqli.so 
extension = pdo_mysql.so
