在centos7上設置certbot和nginx子域

Question

我正在嘗試在Centos7服務器上的Nginx中設置一個帶有一個子域（暫時）的網站，並由Let's Encrypt的certbot提供ssl加密。

我已經成功安裝了nginx，我已經設置了域： example.com www.example.com和ci.example.com並獲得了發行的證書，沒有任何問題（我的瀏覽器說“安全”，它會自動從http重定向到https要求。）

現在，我想讓ci.example.com代理到localhost：6500端口（我相信它稱為proxy_pass ）。 我嘗試過以下內容： 這篇2014年的博客文章，但nginx始終提供標准的“歡迎使用Nginx頁面”。

其他所有文章/教程均針對較舊版本的nginx（不使用/etc/nginx/nginx.conf。

這是/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

我已經弄清楚了，並將其保存以供后代使用。

在運行certbot --nginx命令之前，我沒有正確設置nginx。

這是您應該做的：

從全新安裝的Centos 7

通過sudo yum update -y確保Centos是最新的

然后通過以下方式安裝nginx： sudo yum install nginx -y

它是默認設置，但是可以確保它是最新的。

然后按照本指南操作，使不受保護的http://ci.yoursite.com和http://www.yoursite.com按需要工作。

注-如果由於以下原因而無法啟動Nginx，則有以下問題： [emerg] open() "/usr/share/nginx/logs/ci.yoursite.access.log" failed (13: Permission denied)

使用： su -c "setenforce 0"它將把SELinux設置為許可模式並允許nginx啟動。

然后按照以下步驟操作： 本指南可讓我們開始加密和Certbot --nginx。

在此示例中，最終的/etc/nginx/conf.d/ci.yourserver.conf應該看起來像這樣重新路由到端口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


}
