| + | |||
| + | Monit is a systems software watchdog. It will monitor services to make sure they are running, and take care of them if they get out of control. | ||
| + | ==== Monitoring Modes ==== | ||
| + | |||
| + | There are two ways for monit to operate: as active or passive. Active tries to fix problems while passive only monitors them, but sends alerts when something happens. | ||
| + | |||
| + | ==== Init ==== | ||
| + | |||
| + | * [[upstart]] | ||
| + | |||
| + | For Gentoo / CentOS, add monit to ''/etc/inittab'' and run ''telinit q'' to start the process and keep it respawning upon death. | ||
| + | |||
| + | <code> | ||
| + | # monit | ||
| + | mo:2345:respawn:/usr/bin/monit -Ic /etc/monit/monitrc | ||
| + | </code> | ||
| + | |||
| + | ==== Ubuntu ==== | ||
| + | |||
| + | For Ubuntu, create ''/etc/init/monit.conf''. Check the location of the monit binary, it may be in ''/usr/sbin'' instead of ''/usr/bin'' | ||
| + | |||
| + | <code> | ||
| + | start on runlevel [2345] | ||
| + | stop on runlevel [06] | ||
| + | exec /usr/bin/monit -Ic /etc/monit/monitrc | ||
| + | respawn | ||
| + | </code> | ||
| + | |||
| + | Add monit to the default runlevels: | ||
| + | |||
| + | <code> | ||
| + | update-rc.d monit defaults | ||
| + | service monit start | ||
| + | </code> | ||
| + | |||
| + | ==== CentOS ==== | ||
| + | |||
| + | Download and install the [[http://dev.digitaltrike.com/~steve/downloads/centos/init.d/monit|monit]] init.d script. Make sure that the ''MONIT'' variable in the script points to the correct binary. | ||
| + | |||
| + | Add monit to startup: | ||
| + | |||
| + | <code>chkconfig --levels 235 monit on</code> | ||
| + | |||
| + | ==== FreeBSD ==== | ||
| + | |||
| + | * [[FreeBSD]] | ||
| + | |||
| + | * [[http://beandog.digitaltrike.com/monit/freebsd/|monit samples]] | ||
| + | |||
| + | Add monit to startup: | ||
| + | |||
| + | <code> | ||
| + | echo monit_enable=YES >> /etc/rc.conf | ||
| + | /usr/local/etc/rc.d/monit start | ||
| + | </code> | ||
| + | |||
| + | == Todo == | ||
| + | |||
| + | * Find out how to run monit all the time. See ''man 5 ttys'' for possible reference. | ||
| + | |||
| + | ==== NetBSD ==== | ||
| + | |||
| + | * [[NetBSD]] | ||
| + | |||
| + | <code> | ||
| + | |||
| + | The following files should be created for monit-4.10.1nb2: | ||
| + | |||
| + | /etc/rc.d/monit (m=0755) | ||
| + | [/usr/pkg/share/examples/rc.d/monit] | ||
| + | </code> | ||
| + | |||
| + | ==== Outgoing Email ==== | ||
| + | |||
| + | Monit can be configured to use SocketLabs SMTP relay server to send outgoing email. SocketLabs only supports SSLv3 or no authentication: | ||
| + | |||
| + | <code> | ||
| + | set mailserver smtp.socketlabs.com username <username> password <password> | ||
| + | set mailserver smtp.socketlabs.com port 587 username <username> password <password> using SSLV3 | ||
| + | </code> | ||
