I have a Java web application which, once in a while for reasons I am trying to determine, sometimes becomes unresponsive. I want to give users a simple way of restarting it, via the web, so as I've used ngix a lot in the past, my first thoughts turned to having nginx running on another port, with a URL available which causes a shell script to be run. What would be the easiest, most lightweight, way to do this? Or is there some other way of effecting what I want which I haven't thought of yet?
Using ngx_lua [1]:
location /restart-java-app { content_by_lua 'os.execute("/bin/restart-my-java-app")'; }
But it's blocking, only suitable for personal use ;)
IIRC, Marcus Clyne was working on ngx_shell or something like that? Which can give you shell access based on asynchronous threads that will not block the whole nginx worker process :)
BTW, it's recommended to use the ngx_openresty bundle rather than compile the module yourself: https://github.com/agentzh/ngx_openresty
