我将nginx配置为从我们的服务器提供两个虚拟主机：主主机和子域主机。主要主机是铁路应用程序，与乘客一起服务。它按预期工作。
子域名主机是一个小PHP应用程序。对此子域执行浏览器请求时，它会返回403（禁止）错误。当对特定文件执行浏览器请求时，它会返回502（错误网关）错误。
这是nginx.conf文件：

我认为这是一个权限问题，但我将它们更改为744,755甚至777并仍然遇到相同的错误。
有什么想法吗？

你的nginx配置在第一个视图上看起来很好。我有点担心php-fpm进程。你应该有一个主过程和至少一个孩子，通常不止一个。
您是否配置了php-fpm池？
这就是我的流程的样子
# ps aux | grep "php"
root 1081 0.0 0.3 387316 5404 ? Ss 14:49 0:00 php-fpm: master process (/etc/php-fpm.conf)
nobody 1082 0.0 0.6 390376 10316 ? S 14:49 0:03 php-fpm: pool poolname.com
nobody 1083 0.0 0.6 390388 10360 ? S 14:49 0:03 php-fpm: pool poolname.com
nobody 1084 0.0 0.6 390392 10324 ? S 14:49 0:02 php-fpm: pool poolname.com
您的/etc/php-fpm.conf至少应包含以下内容：
include=/etc/php-fpm.d/*.conf
[global]
pid = /var/run/php-fpm/php-fpm.pid
error_log = /var/log/php-fpm.log
daemonize = yes
然后，您需要在/etc/php-fpm.d/
e.g。 mydomain.com.conf
[mydomain.com]
; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific address on
; a specific port;
; 'port' - to listen on a TCP socket to all addresses on a
; specific port;
; '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = /var/run/php-fpm/php-fpm.sock
; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions..
; Default Values: user and group are set as the running user
; mode is set to 0666
listen.owner = nginx
listen.group = nginx
listen.mode = 0666
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
; will be used.
user = nobody
group = nobody
; Choose how the process manager will control the number of child processes.
; Possible Values:
; static - a fixed number (pm.max_children) of child processes;
; dynamic - the number of child processes are set dynamically based on the
; following directives:
; pm.max_children - the maximum number of children that can
; be alive at the same time.
; pm.start_servers - the number of children created on startup.
; pm.min_spare_servers - the minimum number of children in 'idle'
; state (waiting to process). If the number
; of 'idle' processes is less than this
; number then some children will be created.
; pm.max_spare_servers - the maximum number of children in 'idle'
; state (waiting to process). If the number
; of 'idle' processes is greater than this
; number then some children will be killed.
; Note: This value is mandatory.
pm = dynamic
; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes to be created when pm is set to 'dynamic'.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI.
; Note: Used when pm is set to either 'static' or 'dynamic'
; Note: This value is mandatory.
pm.max_children = 100
; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'
; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
pm.start_servers = 20
; The desired minimum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.min_spare_servers = 5
; The desired maximum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.max_spare_servers = 100
; The number of requests each child process should execute before respawning.
; This can be useful to work around memory leaks in 3rd party libraries. For
; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
; Default Value: 0
pm.max_requests = 250
如果配置设置为完全满意，请重启php-fpm
/etc/init.d/php-fpm restart
您现在应该看到更多进程
ps aux | grep "php"
确保套接字文件存在且由正确的用户拥有（应该是nginx运行的用户）
# ls -l /var/run/php-fpm/php-fpm.sock
srw-rw-rw- 1 nginx nginx 0 Jan 2 14:49 /var/run/php-fpm/php-fpm.sock
现在重新启动你的nginx以确保它读取新的套接字文件
/etc/init.d/nginx restart
希望这会有所帮助。 如果没有，那么其他问题就出现了，我们需要继续调试
