I’m just having some idea for the usage of my vps rather than just for “blog” after reading some threads in the LET.
So, this time I want to write some tutorial about installing Monit in Debian6 32bit.
- This is some easy installation for Monit :
|
1 2 3 4 5 6 7 8 |
Installing Monit : # apt-get install monit Creating a backup of monit control file : # cp /etc/monit/monitrc /etc/monit/monitrc_orig Replace the monit control file with and empty file : # cat /dev/null > /etc/monit/monitrc Editing the monit control file: # nano /etc/monit/monitrc |
- Configuring the Monit control file.Be sure to only put the check to the exist process, otherwise Monit won’t start.Copy paste the following text to the monitrc, and adjust it to your active process.

- Enable the Monit init script :
|
1 2 3 4 5 6 7 8 9 10 |
nano /etc/default/monit # Defaults for monit initscript # sourced by /etc/init.d/monit # installed at /etc/default/monit by maintainer scripts # Fredrik Steen <stone@debian.org> # You must set this variable to for monit to start startup=1 <----- change from 0 to 1 to enable monit # To change the intervals which monit should run uncomment # and change this variable. CHECK_INTERVALS=60 <----- add this line to make monit run every 60 seconds |
- Start the monit :
|
1 |
# /etc/init.d/monit start |
Open the monit page and login using the cresidential you’ve created.
