Nginx 代理几个域到不同的端口

Question

我有一台带有 nginx 监听端口 80 的服务器，并且有多个域名的配置，应该代理到不同端口的连接。

这是我的配置文件：

域1

#This is for redirecting everyone from www.domain.com to domain.com
server {
    listen   80; ## listen for ipv4; this line is default and implied
    #listen   [::]:80 default_server ipv6only=on; ## listen for ipv6

    server_name www.domain1.com;

    return 301 $scheme://domain1.com$request_uri;
}

server {
        listen   80; ## listen for ipv4; this line is default and implied
        #listen   [::]:80 default_server ipv6only=on; ## listen for ipv6

        server_name domain1.com;

        location / {
                proxy_pass http://localhost:8081/;
                proxy_set_header  X-Real-IP  $remote_addr;
        }
}

域2

#This is for redirecting everyone from www.domain.com to domain.com
server {
    listen   80; ## listen for ipv4; this line is default and implied
    #listen   [::]:80 default_server ipv6only=on; ## listen for ipv6

    server_name www.domain2.com;

    return 301 $scheme://domain2.com$request_uri;
}

server {
        listen   80; ## listen for ipv4; this line is default and implied
        #listen   [::]:80 default_server ipv6only=on; ## listen for ipv6

        server_name domain2.com;

        location / {
                proxy_pass http://localhost:8090/;
                proxy_set_header  X-Real-IP  $remote_addr;
        }
}

域3

#This is for redirecting everyone from www.domain.com to domain.com
server {
    listen   80; ## listen for ipv4; this line is default and implied
    #listen   [::]:80 default_server ipv6only=on; ## listen for ipv6

    server_name www.domain3.com;

    return 301 $scheme://domain3.com$request_uri;
}

server {
        listen   80; ## listen for ipv4; this line is default and implied
        #listen   [::]:80 default_server ipv6only=on; ## listen for ipv6

        server_name domain3.com;

        location / {
                proxy_pass http://localhost:8091/;
                proxy_set_header  X-Real-IP  $remote_addr;
        }
}

所有这些配置文件（像往常一样）位于/etc/nginx/sites-available/ 并符号链接到/etc/nginx/sites-enabled/

当我添加第一个文件时，一切都像魅力一样，当我添加第二个文件时，它是相同的，添加第三个文件后，当我尝试执行 service nginx reload 或 service nginx restart 或 service nginx start 时，nginx 停止给我任何消息.

它响应service nginx stop 和service nginx status。显然这些功能有效，但这些先决条件中的其他功能没有响应并且不做任何事情。下面的输出只是从我的控制台复制粘贴。

# service nginx status
[ ok ] nginx is running.
# service nginx reload
# service nginx restart
# service nginx stop
[ ok ] Stopping nginx: nginx.
# service nginx start
# service nginx status
[FAIL] nginx is not running ... failed!
#

如果我删除到第三个文件的符号链接，一切都会再次完美运行。

那么问题来了——我的设置有问题吗？还是我的逻辑？还是使用 nginx？

环境是：

- Debian Squeeze x64
- Nginx version 1.2.6

Answer 1

您遇到的症状表明您的 nginx 配置与第 3 个文件不正确，这就是重新加载失败的原因

nginx -t 的输出应该会告诉您问题出在哪里。
