The presence of nginx on the web page means that the server uses nginx for web. This is not necessarily the case when the nginx interface appears. It may be an nginx test page or an error page. For example, 404, 502, etc., depending on the specific situation.
Error error supplement:
1. The hard disk space is full
Use df -k
to check whether the hard disk space is full. Clearing up hard drive space can resolve 500 errors. If the access log is enabled in nginx, it is best to close the access log when it is not needed.
The access log will occupy a lot of hard disk space.
2. nginx configuration file error
This does not refer to a syntax error. If nginx has a syntax error in the configuration file, it will prompt when it is started. When configuring rewrite, 500 errors may occur if some rules are not handled properly. Please check your rewrite rules carefully. If some variables in the configuration file are set improperly, a 500 error will also occur, such as referencing a variable with no value.
3. If none of the above problems exist, it may be that the number of simulated concurrencies is too much, and you need to adjust the number of concurrency settings in nginx.conf
