# nginx安装与配置

## 准备环境

```shell
yum -y install gcc
yum install -y pcre pcre-devel
yum install -y zlib zlib-devel
```

## 下载

nginx官方下载指定版本源码压缩包

上传到服务器解压

## 编译与安装

```shell
./configure    --prefix=指定安装目录前缀  --with指定额外的模块
make
make install	DESTDIR=指定安装目录后缀
```

## http反向代理配置

* 根据路径分发到不同端口参数配置示例

```
http {
    include       mime.types;
    default_type  application/octet-stream;

	server {
        listen       80;
        server_name  localhost;

        location / {
            root   proxy_pass http://127.0.0.1:8080;
            index  index.html index.htm;
        }
		
		location /fence {
            root   proxy_pass http://127.0.0.1:8081;
            index  index.html index.htm;
        }
		
		location /RfsSniffer {
            root   proxy_pass http://127.0.0.1:8433;
            index  index.html index.htm;
        }
	}
}
```

- 根据域名分发到不同端口参数配置示例

```
http {

    server {
        listen       80;
        server_name  localhost;

        location / {
			proxy_pass http://127.0.0.1:8081;
            index  index.html index.htm;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

    }
	
    server {
        listen       80;
        server_name  location.xumy.vip;

		location / {
			proxy_pass http://127.0.0.1:8081;
            index  index.html index.htm;
        }
        
    }

}
```

## tcp转发

转发https请求,无需在nginx配置ssl证书,nginx版本号必须 >1.15.2,编译时必须配置以下模块

`--with-http_stub_status_module --with-http_ssl_module --with-stream --with-stream_ssl_module  --with-stream_ssl_preread_module`

- 同一个端口监听http与https请求配置示例,$ssl_preread_protocol，可以让stream区分web ssl/tls和其他协议

```
stream {
    upstream http{
		server 127.0.0.1:8081;
    }
	
    upstream https{
		server 127.0.0.1:8433;
    }

    map $ssl_preread_protocol $upstream{
		default http;
		"TLSv1.3" https;
		"TLSv1.2" https;
		"TLSv1.1" https;
		"TLSv1.0" https;
		"TLSv1" https;
		"TLSv2" https;
		"SSLv2" https;
		"SSLv3" https;
    }

    server {
		listen 0.0.0.0:28181;
		ssl_preread on;
		proxy_pass $upstream;
    }

}
```

- http与stream混合使用

```
http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;
    keepalive_timeout  65;

    server {
        listen       80;
        server_name  localhost;

            index  index.html index.htm;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
	
    server {
        listen       80;
