centos7 上设置的 certbot 和 nginx 子域

Question

我正在尝试使用 Let's Encrypt 的 certbot 提供的 ssl 加密在 Centos7 服务器上的 nginx 中设置一个具有一个子域（暂时）的网站。

我已经成功安装了 nginx，我已经设置了我的域：example.com www.example.com 和 ci.example.com 并毫无问题地获得了颁发的证书（我的浏览器显示 'secured' 并且它会自动从 http 请求重定向到 https。）

现在我想让 ci.example.com 代理到 localhost:6500 端口（proxy_pass 我相信它被调用）。我试过以下： this blog post from 2014 但 nginx 一直服务于标准 "Welcome to Nginx page"。

所有其他 articles/tutorials 适用于旧版本的 nginx（不使用 /etc/nginx/nginx.conf.

这里是/etc/nginx/nginx.conf

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;
keepalive_timeout   65;
types_hash_max_size 2048;

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
# for more information.
include /etc/nginx/conf.d/*.conf;

server {
    server_name  example.com www.example.com;

    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 {
    }

    return 301 https://$host$request_uri;
} # managed by Certbot

if ($host = ci.example.com) {
    return 301 https://$host$request_uri;
} #added by me

    listen       80 default_server;
    listen       [::]:80 default_server;
    server_name  example.com www.example.com;
return 404; # managed by Certbot

Answer 1

我已经弄明白了，并把它留给后代。

在我运行 certbot --nginx 命令之前我没有正确设置 nginx。

这是你应该做的：

来自全新安装的 Centos 7

通过sudo yum update -y

确保 Centos 是最新的

然后通过安装nginx：sudo yum install nginx -y

它是默认设置，但这确保它是最新的。

然后按照 this 指南获得不安全 http://ci.yoursite.com 和 http://www.yoursite.com 随心所欲地工作。

注意 - 如果您遇到无法启动 nginx 的问题，原因是： [emerg] open() "/usr/share/nginx/logs/ci.yoursite.access.log" failed (13: Permission denied)

使用：su -c "setenforce 0"它将SELinux设置为permissive模式并允许nginx启动。

然后跟随： This guide 让 Let's Encrypt 和 Certbot --nginx 正常工作。

你的最终 /etc/nginx/conf.d/ci.yourserver.conf 应该看起来像这样重新路由到本例中的端口 6500:

server {

    server_name ci.example.com;
    access_log logs/ci.example.access.log main;

    root /var/www/ci.example.com/html;
    index index.html index.htm;

    location / {
            proxy_pass http://localhost:6500;
            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_connect_timeout 150;
            proxy_send_timeout 100;
            proxy_read_timeout 100;
            proxy_buffers 4 32k;
            client_max_body_size 8m;
            client_body_buffer_size 128k;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "Upgrade";
    }

listen [::]:443 ssl ipv6only=on; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/ci.example.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/ci.example.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

server {
if ($host = ci.example.com) {
    return 301 https://$host$request_uri;
} # managed by Certbot


    listen 80;
    listen [::]:80;

    server_name ci.example.com;
return 404; # managed by Certbot


}
