Hi,
i created the file like this:
#!/bin/bash
curl -o /dev/null --silent --head --write-out '%{http_code}\n'
http://www.mysite.org
it return the http response code.
in monit configuration i do:
check process nginx
with pidfile /dh/nginx/servers/httpd-myserver/var/logs/nginx.pid
start program = "/etc/init.d/nginx start"
stop program = "/etc/init.d/nginx stop"
if failed host www.mysite.org port 80 protocol HTTP then restart #set
your server IP that runs nginx
if 5 restarts with 5 cycles then alert
check program webserverresponse with path /home/myhome/webserver_response.sh
if content == "502" then restart
depends on nginx
When i try start monit:
$ sudo /etc/init.d/monit start
Starting daemon monitor: Syntax error:
/etc/monit/conf.d/nginx.conf:7: Error: syntax error 'webserverresponse'
Monit version: 1:5.1.1-1
thanks
