Nginx error Nginx: [Emerg] Unknown log format "main"

Fault Description:

Reported error after adding Nginx sub-configuration file: [Emerg] Unknown log format "main"

Unable to reload, carefully review the configuration without syntax errors after debugging to find that the definition of Log_format is written to the bottom of the HTTP module, causing the child configuration file to be unrecognized.

The wrong wording

include/opt/app/nginx/conf/conf.d/*.conf; Log_format Main ' $remote _addr-$remote _user [$time _local] "$request" "$status $body _bytes_sent" $h  Ttp_referer "" "$http _user_agent" "$http _x_forwarded_for"; Access_log/opt/logs/nginx/access.log main;}

I introduced the child configuration file before I defined the log format, so the report is not recognized

Workaround:

Write Log_format to the beginning of HTTP

http{Log_format main ' $remote _addr-$remote _user [$time _local] "$request" ' $status $body _bytes_s  Ent "$http _referer" "$http _user_agent" "$http _x_forwarded_for"; Access_log/opt/logs/nginx/access.log main;
