Configuration and deployment of high-performance Web server Nginx (6) Testing common instructions for the main module of the core module

1. Daemon

Meaning: Set whether to run in daemon mode

Syntax: Daemon On|off

Default: On

Example: Daemon off;

Note: Do not use the Daemon directive in the production environment (production mode), these options are for development testing only (development mode).

2. debug_points

Meaning: Breakpoint debugging

Syntax: debug_points [Stop|abort]

Default: None

Example: Debug_points stop;

Note: There are assert assertions within Nginx that allow Nginx to interrupt the program to run, stop, or create a core file with the debugger.

3. master_process

Meaning: Set whether the main process is enabled

Syntax: master_process on|off

Default: On

Example: Master_process off;

Note: Do not use the Master_process directive in the production environment (production mode), these options are for development testing only (development mode).

4. Error_log

Meaning: Specifying the error log file

Syntax: Error_log file [Debug|info|notice|warn|error|crit]

Default: ${prefix}/logs/error.log

Example: Error_log/data/nginx/logs/error.log Debug

Note: This command is not available only in test (or development) mode, but when you add the--with-debug parameter at compile time, you can use the additional parameters of the Error_log directive, namely:

Error_log file [Debug_core|debug_alloc|debug_mutex|debug_event|debug_http|debug_imap];
