Detailed code of Nginx configuration

This article shares with you the detailed code about Nginx configuration. The content is very good. Friends in need can refer to it. I hope it can help everyone.

The previous blog post has already talked about the method of building LNMP environment. After installation, you first need to understand the nginx configuration file: /usr/local/nginx/conf/nginx.conf, I Remove all the comments in the configuration file and those that are temporarily unused, so that it looks cleaner:

// 全局区
worker_processes 1; // 有1个工作的子进程,会占用CPU,可自由设置,一般设置为:CPU数*核数,如果想查看工作中的进程,可以使用命令:ps aux|grep nginx

Event { // 一般是配置nginx连接的特性
　　 worker_connections 1024; // 这是指一个worker能同时允许多少连接

} 

http { //这是配置http服务器的主要段

　#日志管理默认为main格式,记录的内容为: 远程IP:$remote_addr | 用户时间:$remote_user [$time_local] | 请求方法(如GET/POST):$request | 请求状态:$status | 请求体body长度:$body_bytes_sent | referer来源信息:$http_referer | 用户代理/蜘蛛$http-user-agent | 被转发的请求的原始IP:$http_x_forwarded_for()
　　 log_format main '$remote_addr - $remote_user [$time_local] "$request" ' #默认的日志配置
　　　　　　　　　  　　'$status $body_bytes_sent "$http_referer" '
                　　 '"$http_user_agent" "$http_x_forwarded_for"';

    server { //这里整个server的意思就是当你在浏览器中请求127.0.0.1这个地址时,location匹配到后定位到/usr/local/nginx/html/index.html

        listen 80;  #监听端口
        server_name 127.0.0.1; #监听域名
　　　　 access_log  logs/host.access.log  main; #开启日志

        location / {//定位,把特殊的路径或文件再次定位
 　　　 　　　root html;　　#根目录定位,可以使用相对路径,此处所说的根目录为/usr/local/nginx目录,html也是相对于/usr/local/nginx目录,也可使用绝对路径定位,比如你的项目在/var/www/html/目录下,那你就可以改为root /var/www/html/
            index  index.html index.htm;  
        }

　　　　 location ~ \.php$ {//nginx转发PHP请求,碰到.php文件,把根目录定位到html,把请求转交给9000端口PHP进程, 并告诉PHP进程当前的请求的脚本是/scripts$fastcgi_script_name
　　　　　　 root           html;
　　　　　　 fastcgi_pass   127.0.0.1:9000; #默认PHP9000端口
　　　　　　 fastcgi_index  index.php;
　　　　　　 fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
　　　　　　 include        fastcgi_params;
　　　　 }

    }
}
