一、創建nagios用戶和用戶組
[root@localhost ~]#useradd -s /sbin/nologin nagios
[root@localhost ~]#mkdir /usr/local/nagios
[root@localhost ~]#chown -R nagios.nagios /usr/local/nagios
二、開啓系統sendmail服務
[root@localhost ~]#service sendmail start
三、編譯安裝nagios
[root@localhost ~]# tar -zxvf nagios-3.2.0.tar.gz
[root@localhost ~]# cd nagios-3.2.0
[root@localhost nagios-3.2.0]#./configure --prefix=/usr/local/nagios
#指定nagios的安裝目錄，這裏指定nagios安裝到/usr/local/nagios目錄
[root@localhost nagios-3.2.0]#make all
[root@localhost nagios-3.2.0]#make install
# make install用來安裝nagios的主程序,CGI和HTML文件
[root@localhost nagios-3.2.0]# make install-init
#通過make install-init命令可以在/etc/rc.d/init.d目錄下創建nagios啓動腳本
[root@localhost nagios-3.2.0]# make install-commandmode
#通過make install-commandmode命令來配置目錄權限
[root@localhost nagios-3.2.0]# make install-config
#make install-cofig命令用來安裝nagios示例配置文件,這裏安裝的路徑是/usr/local/nagios/etc
nagios安裝完成後，目錄對應的功能說明如下：
bin：可執行程序所在目錄
etc：配置文件所在目錄
sbin：cgi文件所在目錄，也就是執行外部命令所需文件所在目錄
share：網頁文件所在目錄
libexec：外部插件所在目錄
var：日誌文件，lock等文件所在目錄
var/archives：日誌自動歸檔目錄
var/rw：用來存放外部命令文件的目錄
四、安裝nagios的插件
以nagios-plugins-1.4.14爲例，插件版本與nagios版本關係並不大。
[root@localhost nagios]#tar -zxvf nagios-plugins-1.4.14.tar.gz
[root@localhost nagios]#cd nagios-plugins-1.4.14
[root@localhost nagios-plugins-1.4.14]#./configure --prefix=/usr/local/nagios
[root@localhost nagios-plugins-1.4.14]# make
[root@localhost nagios-plugins-1.4.14]# make install
查看/usr/local/nagios/libexec，會看到新增很多的插件。
五、安裝Nagios中文化插件
下載地址：http://sourceforge.net/projects/nagios-cn/files/
此處切忌版本要與nagios的版本對應。
[root@localhost ~]#tar jxvf nagios-cn-3.2.0.tar.bz2
[root@localhost nagios-cn-3.2.0]#cd nagios-cn-3.2.0
[root@localhost nagios-cn-3.2.0]#./configure
[root@localhost nagios-cn-3.2.0]#make all
[root@localhost nagios-cn-3.2.0]#make install
六、配置httpd和php
修改httpd的配置文件/etc/httpd/conf/httpd.conf
找到如下兩行
User apache
Group apache
#如果找不到，請通過搜索nobody尋找
修改爲
User nagios
Group nagios
然後找到
DirectoryIndex index.html index.html.var
修改爲
DirectoryIndex index.html index.html.var index.php
再在其下增加如下行
AddType application/x-httpd-php .php
在配置文件末尾增加如下信息：
#setting for nagios
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
AllowOverride None
Order allow,deny
Allow from all
AuthName "nagios Access"
AuthUserFile /usr/local/nagios/etc/htpasswd
Require valid-user
</Directory>
保存配置文件
七、新增驗證文件
[root@localhost]# /usr/bin/htpasswd -c /usr/local/nagios/etc/htpasswd yilei
New password: (輸入密碼)
Re-type new password: (再輸入一次密碼)
Adding password for useryilei
在/usr/local/nagios/etc下就會新增一個htpasswd驗證文件。
八、驗證
[root@localhost]#service httpd restart
[root@localhost]#service nagios start
通過瀏覽器輸入http://ip/nagios/
輸入用戶名/密碼，就可以看到nagios的管理界面啦。此時看到的界面中沒有任何監控機的信息。
九、配置聯繫人
1、修改contacts.cfg(聯繫人配置文件)
define contact{
contact_name yilei ; Short name of user
use generic-contact ; Inherit default values from generic-contact templ
ate (defined above)
alias yilei Admin ; Full name of user
email [email protected] ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ******
pager 158********
}
聯繫人組
define contactgroup{
contactgroup_name admins
alias Nagios Administrators
members yilei
}
十．配置主機和服務
1.添加主機
Vim hosts.cfg
define host{
use linux-server
host_name ftp
alias yilei-ftp
address 192.168.0.8
}
define host{
use linux-server
host_name ceshi
alias yilei-web2
address 192.168.0.122
}
define host{
use linux-server
host_name web
alias gonpo-web
address gp.gonpo.cn
check_interval 5
retry_interval 1
max_check_attempts 5
check_period 24x7
process_perf_data 0
retain_nonstatus_information 0
contact_groups admins
notification_interval 30
notification_period 24x7
notification_options d,u,r
}
define hostgroup{
hostgroup_name sa-servers
alias sa servers
members ftp,web1,ceshi
}
2.添加服務
Vim services.cfg
efine service{
use local-service
host_name ftp
service_description PING
check_command check_ping!100.0,20%!500.0,60%
}
define service{
use local-service
host_name web
service_description SSH
check_command check_ssh
}
define service{
use local-service
host_name web
service_description HTTP
check_command check_http
}
define service{
use local-service
host_name weibo
service_description check_load
check_command nrpe!check_load
}
2、修改cgi.cfg
default_user_name=yilei ;將用戶名修改爲nagios界面登錄的用戶名
3.修改nagios.cfg
添加
cfg_file=/usr/local/nagios//etc/objects/hosts.cfg
cfg_file=/usr/local/nagios//etc/objects/services.cfg
3、使用命令：/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg檢查配置是否有誤
7、重啓nagios：service nagios restart
