由于网上教程太多了,我就简单写写CentOS 6.5下Nagios 3.2安装过程吧,个人感觉nagios的安装真的很简单,难在熟练使用。

首先安装需要的环境基础,像apache、php、gd、gcc之类的

yum install httpd php gd gd-devel gcc* -y

安装需要的nagios和其插件,nagios监控都是通过插件来实现的

wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-3.2.0.tar.gz

wget http://nagios-plugins.org/download/nagios-plugins-2.0.3.tar.gz

建立nagios用户和目录

useradd nagios

mkdir /usr/local/nagios

chown nagios.nagios /usr/local/nagios/

在下载的目录下进行进行一下命令(这个是从我本机的histroy里粘贴的)

tar zxvf nagios-3.2.0.tar.gz

cd nagios-3.2.0

./configure --prefix=/usr/local/nagios/ --with-gd-lib=/usr/lib --with-gd-inc=/usr/include/

make all

make install

make install-init

make install-config

make install-commandmode

make install-config

tar zxvf nagios-plugins-2.0.3.tar.gz

cd nagios-plugins-2.0.3

 ./configure --prefix=/usr/local/nagios/

make

make install

建立nagios验证用户test

/usr/bin/htpasswd -c /usr/local/nagios/etc/htpasswd test

在apache的配置文件内加上nagios的内容

vi /etc/httpd/conf/httpd.conf

使用Shift g的组合键到最后一行,单击o键,在下一列加如(什么?你不懂?就是vi编译器的使用,快去看看吧~~地址:http://www.linuxidc.com/Linux/2008-01/10860.htm)

#setting for nagios 20070707

ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin

<Directory "/usr/local/nagios/sbin">

    Options ExecCGI

    AllowOverride None

    Order allow,deny

    Allow from all

    AuthName "Nagios Access"

    AuthType Basic

AuthUserFile /usr/local/nagios/etc/htpasswd

    Require valid-user

</Directory>

Alias /nagios /usr/local/nagios/share

<Directory "/usr/local/nagios/share">

    Options None

    AllowOverride None

    Order allow,deny

    Allow from all

    AuthName "Nagios Access"

    AuthType Basic

AuthUserFile /usr/local/nagios/etc/htpasswd

    Require valid-user

</Directory>

修改完了当然重启服务了

service httpd restart

chkconfig httpd on

这样就安装完成了,打开游览器输入http://你部署Nagios服务器的IP/nagios/

你可能出现的问题

1.如果无法打开页面,请查看你系统的防火墙iptables。保证80端口的开放,或者直接关闭防火墙service iptables stop

2.重启apache服务时出现 Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain for ServerName

怎修改下/etc/httpd/conf/httpd.conf,将#ServerName前的#去掉

3.打开浏览器访问Nagios时,部分页面出现 internal server error,这个是eslinux的限制,关闭即可,修改/etc/selinux/config 下的SELINUX=enforcing改为SELINUX=disables,然后reboot重启。

4.页面出现woops!是因为你nagios没有启动,把nagios启动加入开机服务器内:

echo "/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg" >> /etc/rc.local

关于文章中的apache、iptables、selinux等,其实也很有意思的,网上资料也很多,以后有机会再写相关博文吧。
