    There are multiple site config in my nginx, and when I restart the machine, if one of the sites' (vhost) has any error, nginx won't start at all, and those healthy site won't start as a result.

    Maybe I can code a program who detect this case and ignore this vhost and temporary set a template vhost (under maintenance), what do you think about this idea?

    do you know some webserver or script/panel who has this feature ?

    Nginx 1.27.x
    MariaDB 10.x/11.4+
    You can run nginx config debug check command to see if vhost or settings are incorrect
    Code (Text):
    nginx -t

    You can also run "configtest" before restarting Nginx. It will test the config and report any errors before attempting restart:

    Code (Text):
    $ service nginx configtest
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
