開啟Nginx代理HTTPS功能

1、首先檢視是否已經安裝SSL

　openssl version -a

2、生成SSL證書

在nginx目錄下建立ssl檔案夾
cd /etc/pki
mkdir nginx
cd nginx
生成2048位的加密私鑰
openssl genrsa -out server.key 2048
生成證書簽名請求（CSR），這裡需要填寫許多資訊
openssl req -new -key server.key -out server.csr
輸出内容為：
Enter pass phrase for root.key: ← 輸入前面建立的密碼
Country Name (2 letter code) [AU]:CN ← 國家代号，中國輸入CN
State or Province Name (full name) [Some-State]:BeiJing ← 省的全名，拼音
Locality Name (eg, city) []:BeiJing ← 市的全名，拼音
Organization Name (eg, company) [Internet Widgits Pty Ltd]:MyCompany Corp. ← 公司英文名
Organizational Unit Name (eg, section) []: ← 可以不輸入
Common Name (eg, YOUR name) []: ← 伺服器主機名，若填寫不正确，浏覽器會報告證書無效，但并
Email Address []:[email protected] ← 電子郵箱，可随意填
Please enter the following ‘extra’ attributes
to be sent with your certificate request
A challenge password []: ← 可以不輸入
An optional company name []: ← 可以不輸入
生成類型為X509的自簽名證書。有效期設定3650天，即有效期為10年
         openssl x509 -req -days 3650 -in server.csr -signkey server.key -out server.crt           

　　

3、修改Nginx配置檔案

# For more information on configuration, see:
#   * Official English Documentation: http://nginx.org/en/docs/
#   * Official Russian Documentation: http://nginx.org/ru/docs/

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include

    include /etc/nginx/conf.d/*.conf;

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {
		
     }

        error_page 404 /404.html;
            location = /40x.html {
        }

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

# Settings for a TLS enabled server.
#
    server {
        listen       443 ssl http2 default_server;
        listen       [::]:443 ssl http2 default_server;
        server_name  _;
        root         /usr/share/nginx/html;

        ssl_certificate "/etc/pki/nginx/server.crt"; #生成的自簽名檔案
        ssl_certificate_key "/etc/pki/nginx/server.key"; #生成的私鑰檔案
        ssl_session_cache shared:SSL:1m;
        ssl_session_timeout  10m;
        ssl_ciphers HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers on;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

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

}
      

　檢查配置檔案是否正确

nginx -t
      

service nginx reload
