我尝试按照本文中的一些教程进行操作： 在一个 nginx 中配置两个不同的应用程序服务器？
但我无法实现从 qa_server 提供 qa.example.com 和从 staging_server 提供 staging2.example.com 的目标。这是我的 nginx 站点启用文件：
(staging_server) 的内容：
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 $http_host;
proxy_redirect off;
proxy_pass http://puma_staging;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 4G;
keepalive_timeout 10;
ssl on;
ssl_certificate "some cert";
ssl_certificate_key "some key;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers 'something here';
}
(qa_server) 的内容：
upstream puma_qa {
server unix:/home/jenkins/apps/qa_app/shared/tmp/sockets/qa-app-puma.sock fail_timeout=0;
}
server {
server_name qa.example.com;
listen 80;
return 301 https://$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';
}
看起来我的暂存服务器运行良好，我可以跟踪日志并看到日志文件像这样移动tail -f /home/jenkins/apps/staging_app/current/log/staging.log。
我的 qa 应用程序（在临时环境中运行）没有写入正确的日志文件，当我对其进行跟踪时，什么也tail -f /home/jenkins/apps/qa_app/current/log/staging.log没有发生。也就是说，qa.example.com 应用程序可以运行，但不知道它从哪里提供服务。
尝试使用 验证 nginx 配置nginx -t，一切看起来都很好。尝试在调试模式下运行 nginx，以便找出请求究竟从哪里路由/提供服务，就像这样service nginx stop && service nginx-debug start。
正在跟踪访问（/var/log/nginx/access.log）和错误日志（/var/log/nginx/error.log），但我甚至不知道调试日志应该是什么样子。
另一个信息是，我的主机名 staging2.example.com 是指向我服务器 IP 的 A 记录，而我的 qa.example.com 是指向 staging2.example.com 的 CNAME
我在这里犯了什么明显的错误吗？或者我下一步应该尝试什么？
根据评论更新（添加 nginx -T 的输出）：
nginx -T
