Nginx安装配置 -反向代理实现端口转换

##  一、bind() to 0.0.0.0:80 failed ##

###   原因： ###

是由于Windows10系统默认把80端口给占用了，而nginx的端口也是80，所以说报错。

2018/10/27 05:40:15 [emerg] 21724#22312: bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket in a way forbidden by its access permissions)
    2018/10/27 05:41:54 [emerg] 15196#14864: bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket in a way forbidden by its access permissions)

### 解决： ###

### 1、运行中输入regedit进入注册表； ###

HKEY\_LOCAL\_MACHINE\\SYSTEM\\CurrentControlSet\\services\\HTTP

### 找到start，原本是3，我这里改成了4.确认之后重启系统。 ###

### 二、CreateFile() "D:\\Program Files (x86)\\nginx-1.14.0/logs/nginx.pid" failed (2: The system cannot find the file specified) ###

正常情况下D:\\Program Files (x86)\\nginx-1.14.0/logs/nginx.pid，logs目录下会有nginx.pid文件，也有可能该目录下没有这个文件。如果没有，创建一个空文件。参考：[windows系统nginx重启发生异常The system cannot find the file specified][windows_nginx_The system cannot find the file specified]

2018/10/27 05:44:47 [error] 7336#12764: CreateFile() "D:\Program Files (x86)\nginx-1.14.0/logs/nginx.pid" failed (2: The system cannot find the file specified)

### 三、Nginx命令 ###

*  启动：`start nginx.exe`
 *  停止：`nginx.exe -s stop`
 *  重新加载：`nginx.exe -s reload`

### 四、nginx.conf主配置文件 ###

#user  nobody;
    worker_processes  1;
    
    #error_log  logs/error.log;
    #error_log  logs/error.log  notice;
    #error_log  logs/error.log  info;
    
    #pid        logs/nginx.pid;
    
    
    events {
        worker_connections  1024;
    }
    
    
    http {
        include       mime.types;
        default_type  application/octet-stream;
        sendfile        on;
       
        keepalive_timeout  65;
    
        gzip  on;
    	server {
            listen       80;
            server_name  manage.leyou.com;
    
            proxy_set_header X-Forwarded-Host $host;
            proxy_set_header X-Forwarded-Server $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    
            location / {
    			proxy_pass http://127.0.0.1:9001;
    			proxy_connect_timeout 600;
    			proxy_read_timeout 600;
            }
        }
    	server {
            listen       80;
            server_name  api.leyou.com;
    
            proxy_set_header X-Forwarded-Host $host;
            proxy_set_header X-Forwarded-Server $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    
            location / {
    			proxy_pass http://127.0.0.1:10010;
    			proxy_connect_timeout 600;
    			proxy_read_timeout 600;
            }
        }
    }

### 五、`start nginx.exe启动命令` ###

六、web项目路径是localhost：9001

浏览器输入命令：localhost：9001

ps:如果每次都去改host文件的话，比较麻烦，当然也可以实现。这里推荐使用[SwitchHosts][]。

点击ok之后，再去浏览器输入域名即可访问了。
