一、搭建Nagios監控伺服器
1、部署運行環境LAMP
[[email protected] ~]# yum -y install httpd
[[email protected] ~]# systemctl restart httpd
[[email protected] ~]# systemctl enable httpd
[[email protected] ~]# yum -y install mariadb-server mariadb
[[email protected] ~]# systemctl restart mariadb
[[email protected] ~]# systemctl enable mariadb
[[email protected] ~]# mysqladmin -hlocalhost -u root password "123456"
[[email protected] ~]# yum -y install php-mysql php
2、安裝準備:編譯工具 建立使用者和組
[[email protected] /]# rpm -q gcc gcc-c++
[[email protected] /]# useradd nagios
[[email protected] /]# groupadd nagcmd
[[email protected] /]# usermod -G nagcmd nagios
3、安裝源碼包
1) 解包
[[email protected] /]# tar -zxf nagios-4.2.4.tar.gz
[[email protected] /]# cd nagios-4.2.4/
[[email protected] nagios-4.2.4]# ./configure --help | more >分頁查看協助資訊
[[email protected] nagios-4.2.4]# ./configure
--with-nagios-user=nagios \ 所有者
--with-nagios-group=nagcmd \ 從屬組
--with-command-user=nagios \ 軟體執行者
--with-command-group=nagcmd 軟體執行的組
2) 編譯
[[email protected] nagios-4.2.4]# make all >編譯主程式 #做完這步,最好開兩個終端方便查看安裝
[[email protected] nagios-4.2.4]# make install >安裝程式
[[email protected] nagios-4.2.4]# ls /usr/local/nagios/ >主設定檔
[[email protected] nagios-4.2.4]# make install-init >安裝控制指令碼
/usr/bin/install -c -m 755 -d -o root -g root /etc/rc.d/init.d
/usr/bin/install -c -m 755 -o root -g root daemon-init /etc/rc.d/init.d/nagios
Init script installed
[[email protected] nagios-4.2.4]# cat /etc/rc.d/init.d/nagios >系統的指令檔
3、【安裝】
[[email protected] nagios-4.2.4]# make install-commandmode >設定檔案許可權
[[email protected] nagios-4.2.4]# make install-config >安裝配置
[[email protected] nagios-4.2.4]# make install-webconf >部署網站配置
[[email protected] nagios-4.2.4]# make install-exfoliation >頁面風格
4、 查看安裝目錄及設定檔說明
[[email protected] nagios-4.2.4]# ls /usr/local/nagios/
bin/ etc/ libexec/ sbin/ share/ var/
[[email protected] nagios-4.2.4]#ls /usr/local/nagios/bin/
nagios >驗證配置資訊
nagiostats >命令列顯示監控資訊
[[email protected] nagios-4.2.4]#ls /usr/local/nagios/etc/ >主設定檔目錄
[[email protected] nagios-4.2.4]#ls /usr/local/nagios/libexec/ >監控外掛程式目錄 (預設為空白)
[[email protected] nagios-4.2.4]#ls /usr/local/nagios/sbin/ >編譯好的指令檔(二進位)
[[email protected] nagios-4.2.4]#ls /usr/local/nagios/share/ >網頁檔案目錄
[[email protected] nagios-4.2.4]#ls /usr/local/nagios/var/ >日誌目錄
5、安裝監控外掛程式
[[email protected] nagios-plugins-2.1.4]# tar -zxf /nagios-plugins-2.1.4.tar.gz >解包
[[email protected] nagios-plugins-2.1.4]# cd /nagios-4.2.4/nagios-plugins-2.1.4/ >進入目錄
[[email protected] nagios-plugins-2.1.4]# ./configure && make && make install > 源碼安裝
[[email protected] nagios-4.2.4]# ls /usr/local/nagios/libexec/ >查看安裝的外掛程式
6、啟動nagios監控服務
設定訪問監控頁面的使用者名稱(nagiosadmin)和密碼(自訂) >名字為預設值
[[email protected] nagios-4.2.4]# vim /etc/httpd/conf.d/nagios.conf
52 AuthUserFile /usr/local/nagios/etc/htpasswd.users >儲存訪問的使用者名稱和密碼
[[email protected] nagios-4.2.4]# which htpasswd >查看是否有這個命令
/usr/bin/htpasswd
[[email protected] nagios-4.2.4]# rpm -qf /usr/bin/htpasswd >查詢那個包提供的
httpd-tools-2.4.6-40.el7.x86_64
[[email protected] nagios-4.2.4]# htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin >建web系統管理使用者
New password: 111111 >輸入密碼
Re-type new password: 111111 >驗證密碼
-c 選項
[[email protected] nagios-4.2.4]# cat /usr/local/nagios/etc/htpasswd.users >查看產生的檔案
nagiosadmin:$apr1$UGaLKGiO$GNSYq.O2T6qVQab6aKTWR/
[[email protected] nagios-4.2.4]# systemctl restart httpd >重起網站服務
[[email protected] nagios-4.2.4]# /etc/rc.d/init.d/nagios start >開啟nagios服務
[[email protected] nagios-4.2.4]# /etc/rc.d/init.d/nagios status >查看狀態
nagios (pid 3883) is running...
7、訪問監控網頁
[[email protected] 案頭]# firefox http://192.168.4.21/nagios
