Install check_mk on icinga

Preparations before installation:

1. I have already installed icinga and used mysql. check_mk to require that the full-featured Nagios be installed in advance. It seems that I am already full-featured. Now icinga is running normally.

2. Check whether the external command is normal. Open the web page, log on, check the ping service of localhost, and click the drop-down box in the upper right corner:

Click the submit button and perform subsequent operations. Then return to the page and find that the ping service is disabled.

So external command works normally.

3. Check python. Ubuntu server has been installed, which is just version 2.x.

python --versionPython 2.7.3

4. xinetd was installed before NSCA was installed.

Start installation:

1. Download

root@icinga:/opt# wget http://mathias-kettner.com/download/check_mk-1.2.2p1.tar.gz

2. decompress:

tar zxvf check_mk-1.2.2p1.tar.gz

3. Run the./setup. Sh program and enter the interactive installation process. The default value is generally used. The following are my default options:

You have chosen the following directories:  Executable programs             /usr/bin                                 Check_MK configuration          /etc/check_mk                            Check_MK software               /usr/share/check_mk                      documentation                   /usr/share/doc/check_mk                  check manuals                   /usr/share/doc/check_mk/checks           working directory of check_mk   /var/lib/check_mk                        extensions for agents           /usr/lib/check_mk_agent                  configuration dir for agents    /etc/check_mk                            Name of Nagios user             icinga                                   User of Apache process          www-data                                 Common group of Nagios+Apache   icinga-cmd                               Nagios binary                   /usr/local/icinga/bin/icinga             Nagios main configuration file  /usr/local/icinga/etc/icinga.cfg         Nagios object directory         /usr/local/icinga/etc/conf.d             Nagios startskript              /etc/init.d/icinga                       Nagios command pipe             /usr/local/icinga/var/rw/icinga.cmd      Check results directory         /usr/local/icinga/var/spool/checkresults  Nagios status file              /usr/local/icinga/var/status.dat         Path to check_icmp              /usr/lib/nagios/plugins/check_icmp       URL Prefix for Web addons       /                                        Apache config dir               /etc/apache2/conf.d                      HTTP authentication file        /usr/local/icinga/etc/htpasswd.users     HTTP AuthName                   Icinga Access                            PNP4Nagios templates            /usr/share/check_mk/pnp-templates        compile livestatus module       yes                                      check_mk's binary modules       /usr/lib/check_mk                        Unix socket for Livestatus      /usr/local/icinga/var/rw/live            Backends for other systems      /usr/share/check_mk/livestatus           Install Event Console           no                                      

This information already exists ~ /. Check_mk_setup.conf file. If you want to reinstall the file, you can delete the file first.

4. Restart The apache2 and icinga services and open the webpage: http: // 10.112.18.111/check_mk.

See the error message:

Check_mk: Incomplete Apache2 InstallationYou need mod_python in order to run the web interface of check_mk.Please install mod_python and restart Apache.

Now we will install the mod_python module of apache2.

apt-get install libapache2-mod-python

Restart apache2.

Now we can see the page, but there are two errors:

5. Install the agent for local monitoring regardless of the preceding error.

wget http://mathias-kettner.com/download/check-mk-agent_1.2.2p1-2_all.deb

dpkg -i check-mk-agent_1.2.2p1-2_all.deb Selecting previously unselected package check-mk-agent.(Reading database ... 65470 files and directories currently installed.)Unpacking check-mk-agent (from check-mk-agent_1.2.2p1-2_all.deb) ...Setting up check-mk-agent (1.2.2p1-2) ...Reloading xinetd...

6. Modify the host list of the monitor and edit the/etc/check_mk/Main. mk file. The content is as follows:

# Put your host names hereall_hosts = [ 'localhost' ]

7. Check that check_mk will read all hosts and perform detection. 11 detection services are created below.

cmk -Icpu.loads         1 new checkscpu.threads       1 new checksdf                2 new checksdiskstat          1 new checkskernel            3 new checkskernel.util       1 new checkslnx_if            1 new checksmem.used          1 new checksmounts            2 new checkstcp_conn_stats    1 new checksuptime            1 new checks

8. Then, use check_mk-O to automatically modify the configuration file of icinga:

Rolling back.

An error is reported. Because icinga has localhost configuration by default. The simplest solution is to comment out the host definition of localhost in the following file.

/usr/local/icinga/etc/objects/localhost.cfg

#define host{                                                                                                                                                                    #        use                     linux-server            ; Name of host template to use                                                                                          #                                                       ; This host definition will inherit all variables that are defined                                                       #                                                       ; in (or inherited by) the linux-server host template definition.                                                        #        host_name               localhost                                                                                                                                       #        alias                   localhost                                                                                                                                       #        address                 127.0.0.1                                                                                                                                       #        }                                                                                                                      

Run check_mk-o again.
