Nginx https反向代理

接前一篇文章，今天看看https的反向代理怎么配置。

生成自签名证书和私钥

要使用https，首先需要有证书和私钥，这里创建一个测试用的自签名证书和私钥。

使用 openssl 命令生成服务器私钥文件

openssl genrsa -out server.key 2048

生成证书请求

openssl req -new -key server.key -out server.csr

根据私钥和证书请求生成证书

openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

配置反向代理

这里还是使用前一篇文章中使用的python3的 http server 作为后端应用服务。

$ python3 -m http.server 8000

修改 /etc/nginx/nginx.conf 文件，添加反向代理配置

    server {listen       443 ssl;server_name  localhost;ssl_certificate      /etc/nginx/server.crt;ssl_certificate_key  /etc/nginx/server.key;ssl_session_timeout  5m;ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;ssl_prefer_server_ciphers   on;location / {proxy_pass              http://localhost:8000;proxy_http_version      1.1;proxy_set_header        Connection "";proxy_set_header        Host            $host;proxy_set_header        X-Real-IP       $remote_addr;proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;proxy_set_header        X-Forwarded-Proto https;}}

修改后完整的 /etc/nginx/nginx.conf 文件内容如下：

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;events {worker_connections 768;
}http {sendfile on;tcp_nopush on;types_hash_max_size 2048;include /etc/nginx/mime.types;default_type application/octet-stream;ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;ssl_prefer_server_ciphers on;access_log /var/log/nginx/access.log;error_log /var/log/nginx/error.log;gzip on;server {listen 80;server_name localhost;location / {proxy_pass http://localhost:8000;}}server {listen       443 ssl;server_name  localhost;ssl_certificate      /etc/nginx/server.crt;ssl_certificate_key  /etc/nginx/server.key;ssl_session_timeout  5m;ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;ssl_prefer_server_ciphers   on;location / {proxy_pass              http://localhost:8000;proxy_http_version      1.1;proxy_set_header        Connection "";proxy_set_header        Host            $host;proxy_set_header        X-Real-IP       $remote_addr;proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;proxy_set_header        X-Forwarded-Proto https;}}include /etc/nginx/conf.d/*.conf;include /etc/nginx/sites-enabled/*;
}

重新启动服务使配置生效

$ sudo service nginx restart

最后通过访问 “https://localhost” 地址检查请求是否被代理到后端的python应用上了。
