安装 Nagios服务端所需要的软件包
需要web界面显示监控效果，界面的展示主要使用PHP程序，因此需要LAMP环境。
yum install gcc glibc glibc-common -y <##### 升级编译软件
yum install gd gd-devel -y 《######用户后面的PNP出图的包
yum install mysql-server -y 《#####非必需，监控数据库
yum install httpd php php-gd -y 《#####apache、php环境
[[email protected] ~]# rpm -qa mysql httpd php 《####检查LAMP环境
mysql-5.1.73-7.el6.x86_64
php-5.3.3-48.el6_8.x86_64
httpd-2.2.15-54.el6_8.x86_64
创建Nagios服务器需要的用户和组
/usr/sbin/useradd nagios -M -s /sbin/nologin
/usr/sbin/usradd apache -M -s /sbin/nologin
/usr/sbin/usrmod -a -G nagcmd nagios
/usr/sbin/usrmod -a -G nagcmd apache
安装省略。。。。。
字符串检查方法：
[[email protected] objects]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
添加邮件
vi /usr/local/nagios/etc/objects/contacts.cfg +35
修改 [email protected] 为 [email protected]
输入 http://IP/nagios/可进入nagios 监控画面
监控网站显示It appears as though you do not have permission to view information for any of the services you requests...
解决方法：
表用创建的用户没权限，加权限即可：
[[email protected] etc]# sed -i ‘s/nagiosadmin/nagios/g‘ cgi.cfg
[[email protected] etc]# /etc/init.d/nagios reload
Running configuration check...
