Download Merlin from here
Requirements:
Merlin requires Nagios 3.2.4 or later.
Since (at the time of this writing), Nagios 3.2.4 is not yet released, you'll have to use the latest sources cloned from git, using the following command:
git clone git://git.op5.org/nagios.git
and follow the common Nagios installation istructions.
Dependencies:
- libdbi- dbd-mysql
- mysql-libs
- php-mysql
- php-cli
Installation:
Type:
$ make CPPFLAGS="-I/usr/local/include"
Type:
$ sudo sh install-merlin.sh --dest-dir=/usr/local/merlin --nagios-cfg=/usr/local/nagios/etc/nagios.cfg --db-type=mysql --db-user=merlin --db-pass=merlin --db-name=merlin
The output allows you to check the configuration before to start the setup:
Database settings:
Type (--db-type): mysql
Name (--db-name): merlin
Username (--db-user): merlin
Password (--db-pass): merlin
Root Password (--db-root-pass):
Path settings:
Nagios config file (--nagios-cfg): /usr/local/nagios/etc/nagios.cfg
Destination directory (--dest-dir): /usr/local/merlin
libexecdir (--libexecdir): /usr/libexec/merlin
bindir (--bindir): /usr/bin
Base root (--root):
I was unable to install Merlin using a database root password. In case of errors, just keep in mind that could be a problem related to the password.
Stop Nagios typing the following command:
$ /etc/init.d/nagios stop
Start Nagios again
/etc/init.d/nagios start
The output should be:
Starting nagios:Logging to '/usr/local/merlin/logs/neb.log'
