www.nagios.org  下载nagios nagios-plugs nrpe
www.apache.org   下载apache
 
 
1）  安装apache
进入tar包解压路径(tar.gz zxvf 选项解压 tar.bz jxvf选项解压)
cd /usr/httpd-2.2.11
安装
./configure --prefix=/usr/local/apache && make && make install
在安装完nagios后在/usr/local/apache/conf/httpd.conf添加
ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin
 
         AuthType Basic
         Options ExecCGI
         AllowOverride None
         Order allow,deny
         Allow from all
         AuthName "Nagios Access"
         AuthUserFile /usr/local/nagios/etc/htpasswd
         Require valid-user
 
 
 Alias /nagios /usr/local/nagios/share
 
         AuthType Basic
         Options None
         AllowOverride None
         Order allow,deny
         Allow from all
         AuthName "nagios Access"
         AuthUserFile /usr/local/nagios/etc/htpasswd
         Require valid-user
 
或者用Include /usr/nagios-3.06/sample-config/httpd.conf  方式添加
2)安装nagios
   cd /usr/nagios-3.0.6  (nagios 3.1版本tar包有些问题，安装后不能访问目前建议使用低版本)
安装
 a)添加nagios用户
adduser nagios
b）执行安装命令
./configure --prefix=/usr/local/nagios  
make all
make install        
make install-init     ##This installs the init
make install-commandmode  
make install-config    ##将初始的配置文件安装到/usr/local/nagios/etc
 
3）安装nagios-plugs
 
./configure --prefix=/usr/local/nagios/ --enable-redhat-pthread-workaround（此选项针对redhat）
make all
make install
 
4）安装nrpe测试本地
./configure
make all
Install the NRPE plugin (for testing), daemon, and sample daemon config file.
make install-plugin
make install-daemon
make install-daemon-config
Install the NRPE daemon as a service under xinetd.
make install-xinetd
Edit the /etc/xinetd.d/nrpe file and add the IP address of the monitoring server to the only_from directive.
only_from = 127.0.0.1 210.51.4.114
Add the following entry for the NRPE daemon to the /etc/services file.
nrpe 5666/tcp # NRPE
Restart the xinetd service.
service xinetd restart
5）测试nrpe情况
# netstat -at|grep nrpe
tcp        0      0 *:nrpe                  *:*                     LISTEN   
# netstat -an|grep 5666
tcp        0      0 0.0.0.0:5666            0.0.0.0:*               LISTEN  
可以看到5666端口已经在监听了
 
6）执行
/usr/local/nagios/libexec/check_nrpe -H localhost
测试nrpe是否正常工作
7）执行下面命令检查nagios配置
/usr/local/nagios/bin/nagios –v /usr/local/nagios/etc/nagios.cfg
7）执行下面命令启动nagios
 
/usr/local/nagios/bin/nagios –d /usr/local/nagios/etc/nagios.cfg
 
8）为nagios登录界面添加用户及密码
/usr/local/apache/bin/htpasswd –c /usr/local/nagios/etc/htpasswd nagios
9）修改/usr/local/nagios/etc/cgi.cfg
default_user_name=nagios
更改文件内的nagiosadmin为nagiosadmin,nagios
10）chmod 777 /usr/local/nagios/var/rw/nagios.cmd
chmod 777 /usr/local/nagios/var/rw
11）启动apache
/usr/local/apache/bin/apachectl start
通过http://192.168.1.12/nagios访问nagios
 
12)添加开机自启动
echo “/usr/local/apache/bin/apachectl start”  >>  /etc/rc.local
echo “/usr/local/nagios/bin/nagios –d /usr/local/nagios/etc/nagios.cfg”  >>  /etc/rc.local
