Hi guys, i was doing some web server load tests at 2am this morning making some comparisons between 3 webservers. Stupid me did realise it at the time, however, the virtualmin machine crapped itself and i did not realise until i woke up this morning that i had a problem. The webserver continued to serve static html sites, however everything else went down (database connection errors, etc). Virtualmin itself was not accessible either (white screen of death) I was able to perform a hard reset from my service provider control panel, however, this made no difference strangely enough. The solution was to log into the instance using putty and perform /etc/init.d/webmin start
2 problems
Problem one
from the logs, it appears that at some point last night, php and mysqli stopped functioning?

Second problem
Upon looking at the logs further, i came across something i do not quite understand. A website, that was once on a virtualmin server on google cloud compute (but is not, nor has it ever been, on my current virtualmin vultr server) is referred to in the logs...??
[Tue Apr 02 23:02:14.606719 2019] [autoindex:error] [pid 13114] [client 82.102.18.148:54334] AH01276: Cannot serve directory /home/virtualserver_user/public_html/: No matching DirectoryIndex (index.html,index.htm,index.php,index.php4,index.php5) found, and server-generated directory index forbidden by Options directive, referer: https://domain.com.au/
when i enter the url in the above log into a web broswer...i am redirected to the parent website on my current virtualmin webserver. How is this possible when that particular URL is not even on this server?
IS it enough to put in place the following...
check on schedule? = "Yes and default reporting mode" failures before reporting = 1 Also send email for this service to = my-email@mydomain.com
Webmin>Others>System and Server Status>Apache Webserver>Commands to run>If monitor goes down, run command>
service apache2 startRemembering to also select
Run commands on = "this server"
Is the following the right command to also setup an auto restart for Mysql?
service mysql startor do i need to use
service msyqld startin Webmin>bootup and shutdown...I am a little confused by the following:
