下载nagios nagios-plugs nrpe
下载apache
1） 安装apache
进入tar包解压路径( 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/f添加
ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin
<Directory "/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
</Directory>
Alias /nagios /usr/local/nagios/share
<Directory "/usr/local/nagios/share">
AuthType Basic
Options None
rubyinstaller包解压后怎么安装 AllowOverride None
Order allow,deny
Allow from all
AuthName "nagios Access"
AuthUserFile /usr/local/nagios/etc/htpasswd
Require valid-user
</Directory>
或者用Include /usr/nagios-3.06/f 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
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
make install
4）安装nrpe测试本地
# ./configure --prefix=/usr/local/nagios --enable-ssl
make all
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 <nagios_ip_address>
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/d
chmod 777 /usr/local/nagios/var/rw
11）启动apache
/usr/local/apache/bin/apachectl start
通过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
/i?d=1 如缺少监控脚本可在此站下载
客户端安装配置
在客户端只需安装nagios-plugin nrpe
安装步骤与服务端相同
安装完成之后修改其相关配置
Vi /etc/xinetd.d/nrpe 修改only_from添加服务端IP
only_from = 127.0.0.1 192.168.6.252（服务端IP）
vi $nagioshome/etc/nrpe.cfg 添加相关command命令
重启xinetd服务
从服务端测试nrpe通信
/usr/local/nagios/libexec/check_nrpe -H IP(客户端IP)
配置相关cfg文件（可参考田逸相关nagios文档）
手动添加hosts.cfg
define host{
host_name 254-test
address 192.168.6.254
check_command check-host-alive
contact_groups test
max_check_attempts 5
notification_interval 10
notification_period 24x7
notification_options d,u,r
}
添加hostgroups.cfg
define hostgroup{
hostgroup_name game-hosts ; The name of the hostgroup
members hm1-1,hm5-1,hm9-1,hm7-1,hm8-1 ; Comma separated list of hosts that belong to this group
}
添加服务services.cfg
define service{
host_name *
service_description traffic
check_command check_nrpe_traffic
contact_groups test
check_period 24x7
max_check_attempts 4
normal_check_interval 3
retry_check_interval 2
contact_groups test
