6.建立二進位命令,CGI,html檔案

[[email protected] nagios-4.4.1]# make install

7.安裝相關的進程檔案(安裝啟動指令碼),增加httpd開機啟動,nagios開機啟動

[[email protected] nagios-4.4.1]# make install-daemoninit/usr/bin/install -c -m 755 -d -o root -g root /etc/init.d/usr/bin/install -c -m 755 -o root -g root startup/default-init /etc/init.d/nagios*** Init script installed ***

[[email protected] nagios-4.4.1]# chkconfig --level 2345 httpd on
[[email protected] nagios-4.4.1]# chkconfig --list | grep httpd
httpd              0:off    1:off    2:on    3:on    4:on    5:on    6:off
[[email protected] nagios-4.4.1]# chkconfig --list | grep nagios
nagios             0:off    1:off    2:on    3:on    4:on    5:on    6:off

8.安裝外部命令檔案

[[email protected] nagios-4.4.1]# make install-commandmode
/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/var/rw
chmod g+s /usr/local/nagios/var/rw

*** External command directory configured ***

9.安裝設定檔

[[email protected] nagios-4.4.1]# make install-config/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc/objects/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/nagios.cfg /usr/local/nagios/etc/nagios.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/cgi.cfg /usr/local/nagios/etc/cgi.cfg/usr/bin/install -c -b -m 660 -o nagios -g nagios sample-config/resource.cfg /usr/local/nagios/etc/resource.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/templates.cfg /usr/local/nagios/etc/objects/templates.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/commands.cfg /usr/local/nagios/etc/objects/commands.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/contacts.cfg /usr/local/nagios/etc/objects/contacts.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/timeperiods.cfg /usr/local/nagios/etc/objects/timeperiods.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/localhost.cfg /usr/local/nagios/etc/objects/localhost.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/windows.cfg /usr/local/nagios/etc/objects/windows.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/printer.cfg /usr/local/nagios/etc/objects/printer.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/switch.cfg /usr/local/nagios/etc/objects/switch.cfg*** Config files installed ***Remember, these are *SAMPLE* config files.  You‘ll need to readthe documentation for more information on how to actually defineservices, hosts, etc. to fit your particular needs.

備忘:這些都是一些樣本設定檔,同時比如nagios.cfg在啟動nagios的時候需要使用到.

10.安裝apache設定檔即httpd設定檔

[[email protected] nagios-4.4.1]# make install-webconf/usr/bin/install -c -m 644 sample-config/httpd.conf /etc/httpd/conf.d/nagios.confif [ 0 -eq 1 ]; then         ln -s /etc/httpd/conf.d/nagios.conf /etc/apache2/sites-enabled/nagios.conf;     fi*** Nagios/Apache conf file installed ***

11.配置防火牆或者關閉防火牆

配置允許8連接埠進入:
iptables -I INPUT -p tcp --destination-port 80 -j ACCEPTservice iptables save
關閉防火牆,關閉開機啟動:

service iptables stop
[[email protected] nagios-4.4.1]# chkconfig --level 2345 iptables off
[[email protected] nagios-4.4.1]# chkconfig --list | grep iptables
iptables           0:off    1:off    2:off    3:off    4:off    5:off    6:of

12.建立nagios管理帳號

[[email protected] nagios-4.4.1]# htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadminNew password:                           #輸入新密碼Re-type new password:                   #再次輸入密碼,進行確認Adding password for user nagiosadmin

13.啟動apache服務,nagios core服務

[[email protected] nagios-4.4.1]# service httpd start[[email protected] nagios-4.4.1]# service nagios start

14.通過頁面進行訪問測試

訪問地址:http://192.168.53.25/nagios    輸入nagios管理帳號,密碼進行登入.

 登入成功之後,頁面如下:

查看Hosts,Services有如下的報錯:

備忘:以上錯誤提示,表示沒有某些命令,即在/usrlocal/nagios/libexex中滅有命令,需要安裝nagios-plugins來安裝相應的命令

15.下載,上傳nagios-plugins壓縮包

:

https://www.nagios.org/downloads/nagios-plugins/

 軟體包:nagios-plugins-2.2.1.tar.gz

[[email protected] softwares]# cd /opt/softwares/;ls -l nagios-plugins*-rw-r--r--. 1 root root 2728818 Jul 31 12:25 nagios-plugins-2.2.1.tar.gz

16.安裝依賴的軟體包,解壓,編譯,安裝

yum install -y gcc glibc glibc-common make gettext automake autoconf wget openssl-devel net-snmp net-snmp-utils

[[email protected] softwares]# tar zxf nagios-plugins-2.2.1.tar.gz [[email protected] softwares]# cd nagios-plugins-2.2.1[[email protected] nagios-plugins-2.2.1]# ./configure 
[[email protected] nagios-plugins-2.2.1]# make
[[email protected] nagios-plugins-2.2.1]# make install

備忘:外掛程式安裝完成

17.重新在nagios頁面進行測試,在HOSTS中的localhost的命令菜單中點擊."Re-schedule the next check",查看hosts狀態

備忘:說明命令已經成功,對於services中的檢查,也會在一定時間之後,達到調度時間進行狀態的修改.

Servies的狀態:

18.針對HTTP的檢查,在本地的/var/www/html中建立index.html檔案就可以解決這個警告

[[email protected] libexec]# cd /var/www/html/[[email protected] html]# touch index.html

 配置完成之後,http服務的狀態:

到此,所有的nagios-core,nagios-plugins已經安裝完成!
