我嘗試了以下一些教學和本文： 在一個 nginx 中設定兩個不同的應用程式伺服器？
但我並沒有實現從 qa_server 提供 qa.example.com 並從 staging_server 提供 staging2.example.com 的目標。這是我的 nginx 網站啟用檔案：
(staging_server) 的內容：
upstream puma_staging {
server unix:/home/jenkins/apps/staging_app/shared/tmp/sockets/staging-app-puma.sock fail_timeout=0;
}
server {
server_name staging2.example.com;
listen 80;
return 301 https://$host$request_uri;
}
server {
server_name staging2.example.com;
listen 443 default_server;
root /home/jenkins/apps/staging_app/current/public;
try_files $uri/index.html $uri @puma_staging;
location @puma_staging {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto https;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://puma_staging;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 4G;
keepalive_timeout 10;
ssl on;
ssl_certificate "some cert";
ssl_certificate_key "some key;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers 'something here';
}
(qa_server) 的內容：
upstream puma_qa {
server unix:/home/jenkins/apps/qa_app/shared/tmp/sockets/qa-app-puma.sock fail_timeout=0;
}
server {
server_name qa.example.com;
listen 80;
return 301 https://$host$request_uri;
}
### QA START ###
server {
server_name qa.example.com;
listen 443;
root /home/jenkins/apps/qa_app/current/public;
try_files $uri/index.html $uri @puma_qa;
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto https;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_redirect off;
proxy_read_timeout 150s;
proxy_pass http://puma_qa;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 4G;
keepalive_timeout 10;
ssl on;
ssl_certificate "some cert";
ssl_certificate_key "some key;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers 'something here';
}
看起來我的臨時伺服器工作得很好，我可以追蹤日誌並看到日誌檔案像這樣移動tail -f /home/jenkins/apps/staging_app/current/log/staging.log。
tail -f /home/jenkins/apps/qa_app/current/log/staging.log當我像什麼都沒發生一樣跟踪它時，我的 qa 應用程式（在臨時環境中運行）不會寫入正確的日誌檔案。也就是說，qa.example.com 應用程式可以正常運行，但不知道它是從哪裡提供服務的。
嘗試使用 驗證 nginx 配置nginx -t，一切看起來都很好。嘗試在偵錯模式下執行 nginx，以便我找出要求的確切路由/服務位置，如下所示service nginx stop && service nginx-debug start。
追蹤存取（/var/log/nginx/access.log）和錯誤日誌（/var/log/nginx/error.log），但我甚至不知道偵錯日誌應該是什麼樣子。
另一個資訊是我的主機名稱 staging2.example.com 是指向我伺服器 IP 的 A 記錄，而我的 qa.example.com 是指向 staging2.example.com 的 CNAME
我在這裡犯了什麼明顯的錯誤嗎？或者我接下來應該嘗試什麼？
根據評論更新（添加 nginx -T 的輸出）：
nginx -T
