4.4 Web 安装centreon完成后

### 参考链接:http://www.xodino.it/?page_id=968

Finalize Centreon configuration:

Open in webrowser: "http://<yourserverip>/centreon/", replace "<yourserverip>" with your Centreon server ip address or hostname.

 

Go to: Configuration -> Nagios -> cgi (in sidebar), Press on "CGI.cfg" link

Change settings to some options, as writed below:

- Physical HTML Path: /usr/share/nagios3/htdocs

- URL HTML Path : /nagios3

- Nagios Process Check Command: /usr/lib/nagios/plugins/check_nagios /var/cache/nagios3/status.dat 5 '/usr/sbin/nagios3'

Press Save

 

Go to: Configuration -> Nagios -> nagios.cfg (in sidebar), Press on "Nagios CFG 1" link, you should be in "Files" section of the configuration screen.

Make sure to set folowing configuration values:

- Log File : /var/log/nagios3/nagios.log

- Downtime File : /var/lib/nagios3/downtime.dat

- Comment File : /var/lib/nagios3/comment.dat

- Temp File : /var/cache/nagios3/nagios.tmp

- P1 File : /usr/lib/nagios3/p1.pl

- Lock File : /var/run/nagios3/nagios3.pid

- Object Cache File : /var/cache/nagios3/objects.cache

- Status File : /var/cache/nagios3/status.dat

- External Command File : /var/lib/nagios3/rw/nagios.cmd

 

Now Press on "Logs Options" tab to go to "Logs Options" section.

Make sure to set folowing configuration values:

- Log Archive Path : /var/log/nagios3/archives/

- State Retention File : /var/lib/nagios3/retention.dat

Press Save

 

Go to: Administration -> Options -> CentStorage (in sidebar)

Make sure to set folowing configuration values:

- Nagios current log file to parse: /var/log/nagios3/nagios.log

Press Save

 

Now let's apply our changes, go to: Configuration -> Nagios

Select as below:

- Generate Configuration Files

- Include Comments

- Run Nagios debug (-v)

- Move Export Files

- Restart Nagios

- Method: "External Command"

Press Export

 

This will restart Nagios & apply all changes you made in Web Interface.

You will do it every time you make changes, e.g. adding/modifying of hosts, commands, contacts, services...etc...

 

The installation of Centreon is completed.

 

Final fixes (very important):

Go to terminal console, then...

 

In Debian/Ubuntu the user "nagios" is set to "/bin/false" shell. Because of it "centcore" and "centstorage" daemons won't start. A reason for that is because those daemons use "su -c" command which requires a real shell, so the shell for

 

"nagios" user must be set to "/bin/sh":

# usermod -s /bin/sh nagios

 

Apply permissions for Web interface to be able to send "External Commands", perform the following commands to change directory permissions and to make the changes permanent:

# invoke-rc.d nagios3 stop

# dpkg-statoverride --update --add nagios www-data 2710 /var/lib/nagios3/rw

# dpkg-statoverride --update --add nagios nagios 751 /var/lib/nagios3

 

Add htaccess user with password "P@ssw0rd" for nagios CGI:

# htpasswd -bc /etc/nagios3/htpasswd.users nagiosadmin P@ssw0rd

 

Allow SNMP readonly access:

# echo "rocommunity public" > /etc/snmp/snmpd.conf

 

If you want to allow SNMP access only for localhost then use this instead:

# echo "rocommunity public 127.0.0.1" > /etc/snmp/snmpd.conf

 

# ls -al /usr/lib/nagios/plugins  //查看权限,需要具有sudo权限

# cd /usr/lib/nagios/

# chmod -R u+s plugins   //权限修改成 -rwsr-xr-x

### 不修改权限会报:Warning: This plugin must be either run as root or setuid root.

Now, restart the server

# reboot

4.5 常规信息监控

4.5.1激活配置

# /etc/init.d/nagios3 reload

# /etc/init.d/centcore restart or start

# /etc/init.d/centstorage restart or start

# /etc/init.d/ndoutils restart

# /etc/init.d/nagios-nrpe-server restart

4.5.2监控本机

1)配置监控主机

2)定义主机服务

Go to: Configuration -> Serivces -> Add -> Services by host

Add---关系(Relations)保存后生效,然后激活配置

4.5.3通过nrpe插件监控本机

1)定义check_nrpe命令

命令名:check_nrpe

命令行:$USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$

Go to: Configuration -> Commands -> Checks -> Add -> Services by host

2nrpe常用模版修改

# vim /etc/nagios/nrpe.cfg

# The following examples use hardcoded command arguments...

command[check_users]=/usr/lib/nagios/plugins/check_users -w 5 -c 10

command[check_load]=/usr/lib/nagios/plugins/check_load -w 15,10,5 -c 30,25,20

#command[check_hda1]=/usr/lib/nagios/plugins/check_disk -w 20% -c 10% -p /dev/hda1

command[check_disk]=/usr/lib/nagios/plugins/check_disk -w 20% -c 10% -p /

command[check_zombie_procs]=/usr/lib/nagios/plugins/check_procs -w 5 -c 10 -s Z

command[check_total_procs]=/usr/lib/nagios/plugins/check_procs -w 150 -c 200

3)添加check_load

Go to: Configuration -> Services -> Templates -> Add -> Save

依次对照填写以下内容

3)关联模版

因为 Centreon-Server继承的是generic-host主机模板,所以我们在generic-host模板里将刚才的服务模板都关联上

Go to: Configuration -> HOsts -> Templates -> generic-host –> Relations

Go to: Configuration -> HOsts -> Centreon-Server

再次查看Centreon-Serve服务,已经生成  //若没有以下状态,可以重启nagios-nrpe-server ndoutils 服务

Go to: Monitoring -> Services -> All Serveices

4.6.3 web centreon configuration

1Go to: Configuration -> HOsts -> Templates ->Servers-Linux –> Relations -> Save

   

2Go to: Configuration -> HOsts -> Add –> Save

   
   
 
 

 

 

 

4.6 可能的报错信息

1)报错解决:

Error: Could not create external command file '/var/log/nagios3/rw/nagios.cmd'

解决:mkdir /var/log/nagios3/rw

Chown nagios.nagios rw

2)在线安装ndoutils,启动ndo2前一定要修改:/etc/default/ndoutils

ENABLE_NDOUTILS=1
