调整PHP配置文件

php有三个配置文件:

php.ini 主配置文件
php-fpm.conf 进程服务配置文件
www.conf 扩展配置文件

调整主配置文件:

cp /opt/php-7.1.10/php.ini-development /usr/local/php/lib/php.ini
vim /usr/local/php/lib/php.ini
第1170行需要修改
mysqli.default_socket = /usr/local/mysql/mysql.sock
第939行需要取消注释,修改
date.timezone = Asia/Shanghai

php -m                  #验证安装的模块

PHP-FPM(FastCGI Process Manager: FastCGI进程管理器)是一个PHPFastCGI管理器，由于Nginx服务器不能处理动态页面，需要由Nginx把动态请求交给php-fpm进程进行解析。

配置Nginx支持PHP解析

vim /usr/local/nginx/conf/nginx.conf
第65行需要取消注释,修改
location ~ \.php$ {
    root           html;
    fastcgi_pass   127.0.0.1:9000;
	fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;   #将 /scripts修改为nginx的工作目录
	include        fastcgi_params;
}	
	
systemctl restart nginx.service

数据库名字: bbs
数据库用户名:bbsuser
