Installing Monit :–<\/p>\n
<\/p>\n
sudo apt-get install monit<\/p>\n
This command will install Monit on Ubuntu.<\/p>\n
In order to Start the Monit we need to edit file\u00a0 “\/etc\/default\/monit” and set the\u00a0 “startup= 1”<\/p>\n
This will start the Monit, but we need to do the real work inside the “\/etc\/monit\/monirc”\u00a0 file, and mention what all services we want to be monitored.<\/p>\n
I have simply added a script for monitoring my Nginx Server<\/p>\n
check process nginx with pidfile \/var\/run\/nginx.pid
\nstart program = “\/etc\/init.d\/nginx start”
\nstop program\u00a0 = “\/etc\/init.d\/nginx stop”
\ngroup www-data<\/p>\n
But before that we need to enable few other services as well like:–<\/p>\n
set daemon\u00a0 20\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 # check services at 2-minute intervals<\/p>\n
set logfile syslog facility log_daemon\u00a0\u00a0\u00a0 #for log analysis<\/p>\n
set httpd port 2812 and
\nuse address localhost\u00a0 # only accept connection from localhost
\nallow localhost\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 # allow localhost to connect to the server and
\nallow admin:monit\u00a0\u00a0\u00a0\u00a0\u00a0 # require user ‘admin’ with password ‘monit’
\n#\u00a0\u00a0\u00a0\u00a0 allow @monit\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 # allow users of group ‘monit’ to connect (rw)
\n#\u00a0\u00a0\u00a0\u00a0 allow @users readonly\u00a0 # allow users of group ‘users’ to connect readonly<\/p>\n
<\/p>\n
Once am done with this i will restart monit and see the status on localhost:2812 , we will see the status saying nginx is running.<\/p>\n
let kill or stop Nginx and see the same url, you will see a message saying Nginx is stopped.<\/p>\n
<\/p>\n
As we have asked the monit to check and restart the service at 2 minutes, you will see the process up and running again.<\/p>\n
