编译安装完成后PHP不具备配置文件php.ini，此时只需复制php.ini-production到 /usr/local/lib/php.ini即可,php.ini文件一般在/usr/local/lib/和/etc目录下

[root@localhost php-7.1.2]# cp php.ini-production /usr/local/lib/php.ini

此时只需复制php-fpm的配置文件在安装php时提供的配置文件的模版/usr/local/php/etc/php-fpm.conf.default到相应/usr/local/php/etc/php-fpm.conf即可

创建test.php测试nginx是否支持PHP
下面我们在/data/webroot这个目录下新建一个PHP页面测试网页，文件名为test.php

1 <?php  
2 phpinfo();  
3 ?>  

然后重启php和nginx
[root@redhat7 php-7.1.2]# service php-fpm restart 
Gracefully shutting down php-fpm . done
Starting php-fpm  done
[root@redhat7 php-7.1.2]# service nginx restart 
Restarting nginx (via systemctl):                          [  确定  ]
重启PHP与nginx后  我们在浏览器中输入http://192.168.42.131/test.php
