在icinga上安裝check_mk

安裝前的準備：

1. 我現在已經安裝了icinga，並且使用了mysql. check_mk要求事先安裝了全功能的nagios, 似乎我的已經算是全功能了。現在運行icinga也正常。

2. 檢查external command是否正常。開啟網頁，登入後勾選localhost的ping服務， 然後點擊右上的下拉框：

點擊Submit按鈕後，接著做一些後續操作。然後回到頁面發現Ping服務被禁止了。

所以external command工作正常。

3. 檢查python， UBuntu server已經安裝好了，剛好是2.x版本。

python --versionPython 2.7.3

4. xinetd 在之前安裝NSCA的時候就裝過了。

開始安裝：

1. 下載

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

2. 解壓：

tar zxvf check_mk-1.2.2p1.tar.gz

3. 運行./setup.sh 程式，進入互動式安裝過程，一般都用預設值。下面是我的預設選擇：

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                                      

這些資訊都存在了~/.check_mk_setup.conf檔案裡面。下次如果想重新安裝，可以先刪除這個檔案。

4. 重新啟動apache2和icinga服務後，開啟網頁：http://10.112.18.111/check_mk

看到錯誤資訊：

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.

現在來安裝Apache2的模組mod_python.

apt-get install libapache2-mod-python

重新啟動apache2.

現在看到頁面了，但是有兩個錯誤：

5. 先不管上面的錯誤，安裝一下本機監控用的agent。

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. 修改監控的host列表, 編輯/etc/check_mk/main.mk檔案，內容如下：

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

7. 檢測一下， check_mk會讀取所有host並進行檢測，下面建立了11個檢測服務。

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. 然後用check_mk -O 來自動修改icinga的設定檔：

報錯了。因為icinga預設有localhost配置。最簡單的解決方案是把下面的檔案裡面的localhost的host定義注釋掉

/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                                                                                                                                       #        }                                                                                                                      

再次運行check_mk -O ，成功。
