Nagios監控系統
安裝Nagios監控系統
1.安裝LAMP或者LNMP架構
2.創建nagios用戶和用戶組
useradd -s /sbin/nologin nagios
3.安裝依賴包
yum -y install gcc perl unzip openssl-devel
4.下載編譯安裝Nagios
tar zxf nagios-cn.4.3.4.tar.gz
cd nagios-4.3.4/
./configure --prefix=/usr/local/nagios
make all && make install && make install-init && make install-commandmode && make install-config
5.生成nagios模板文件
make install-webconf
6.創建訪問認證文件
touch /usr/local/nagios/etc/htpasswd.users
htpasswd /usr/local/nagios/etc/htpasswd.users nagiosadmin
注意這裏的nagiosadmin是用戶名，是由/usr/local/nagios/etc/下的cgi.conf文件定義的，要修改還要修改cgi.conf文件
7.啓動httpd服務和ngios服務
systemctl start httpd && systemctl enable httpd
systemctl start nagios && systemctl enable nagios
8.訪問網頁http://192.168.11.25/nagios/
這裏輸入你創建的用戶和密碼
然後進入網頁（如下圖所示）
9.編譯安裝Nagios插件nagios-plugins
tar zxf nagios-plugins-2.1.2.tar.gz
cd nagios-plugins-2.1.2
./configure --prefix=/usr/local/nagios
make && make install
10.編譯安裝Nagios插件nrpe
tar zxf nrpe-3.2.1.tar.gz
cd nrpe-3.2.1
./configure
make all && make install-plugin && make install-daemon
