Nagios添加服務(wù)監(jiān)控-創(chuàng)新互聯(lián)

監(jiān)控Web服務(wù):

創(chuàng)新互聯(lián)基于成都重慶香港及美國等地區(qū)分布式IDC機房數(shù)據(jù)中心構(gòu)建的電信大帶寬，聯(lián)通大帶寬，移動大帶寬，多線BGP大帶寬租用,是為眾多客戶提供專業(yè)服務(wù)器托管報價，主機托管價格性價比高，為金融證券行業(yè)川西大數(shù)據(jù)中心，ai人工智能服務(wù)器托管提供bgp線路100M獨享，G口帶寬及機柜租用的專業(yè)成都idc公司。

在window server2003上安裝IIS

然后我們在nagios上做配置

命令配置里面默認有http

define command{

command_name check_http

command_line $USER1$/check_http -I $HOSTADDRESS$ $ARG1$

}

配置主機和服務(wù)，主機之前已經(jīng)配置好了，所以我們添加一個服務(wù)就可以

[nagios@node4 ~]$ cd/usr/local/nagios/etc/objects/

[nagios@node4objects]$ vim windows.cfg

define service{

use generic-service

host_name winserver

service_description Web_server

check_command check_http

}

重啟nagios服務(wù)

[root@node4 objects]#service nagios restart

Running configurationcheck...done.

Stopping nagios:done.

Starting nagios:done.

然后現(xiàn)在我們在nagios管理界面上看到新加入的web服務(wù)了

Nagios添加服務(wù)監(jiān)控

監(jiān)控mysql服務(wù)

在node4上安裝mysql-server

# yum install mysql-server -y

啟動mysqld服務(wù)

# service mysqldstart

Initializing MySQLdatabase: Installing MySQL systemtables...

Filling helptables...

To start mysqld atboot time you have to copy

support-files/mysql.serverto the right place for your system

PLEASE REMEMBER TOSET A PASSWORD FOR THE MySQL root USER !

To do so, start theserver, then issue the following commands:

/usr/bin/mysqladmin-u root password 'new-password'

/usr/bin/mysqladmin-u root -h node4.example.com password 'new-password'

Alternatively you canrun:

/usr/bin/mysql_secure_installation

which will also giveyou the option of removing the test

databases andanonymous user created by default. Thisis

strongly recommendedfor production servers.

See the manual formore instructions.

You can start theMySQL daemon with:

cd /usr ;/usr/bin/mysqld_safe &

You can test theMySQL daemon with mysql-test-run.pl

cd /usr/mysql-test ;perl mysql-test-run.pl

Please report anyproblems with the /usr/bin/mysqlbug script!

[ OK ]

Starting mysqld: [ OK ]

# chkconfig mysqld on

然后給mysql設(shè)置管理員密碼

# mysqladmin -u root -p password wiker #修改密碼為wiker

Enter password: #直接回車，默認的root密碼是空

[root@node4 ~]# mysql -u root -pwiker #測試下登陸

但是我們發(fā)現(xiàn)我們沒有check_mysql這個插件：

[root@node4 libexec]#pwd

/usr/local/nagios/libexec

[root@node4 libexec]#ls

check_apt check_imap check_pop

check_breeze check_ircd check_procs

check_by_ssh check_load check_real

check_clamd check_log check_rpc

check_cluster check_mailq check_sensors

check_dhcp check_mrtg check_smtp

check_dig check_mrtgtraf check_ssh

check_disk check_nagios check_swap

check_disk_smb check_nntp check_tcp

check_dns check_nrpe check_time

check_dummy check_nt check_udp

check_file_age check_ntp check_ups

check_flexlm check_ntp_peer check_users

check_ftp check_ntp_time check_wave

check_http check_nwstat negate

check_icmp check_oracle process_perfdata.pl

check_ide_smart check_overcr urlize

check_ifoperstatus check_ping utils.pm

check_ifstatus check_pnp_rrds.pl utils.sh

因為check_mysql這個插件需要依賴mysql-devel包才能生效，所以我們需要安裝這個包，然后重新編譯nagios的插件

# yum installmysql-devel -y

[root@node4nagios-plugins-1.5]# ./configure--with-nagios-user=nagios --with-nagios-group=nagios

[root@node4nagios-plugins-1.5]# make ; make install

[root@node4nagios-plugins-1.5]# cd /usr/local/nagios/libexec/

[root@node4 libexec]#ls

check_apt check_load check_real

check_breeze check_log check_rpc

check_by_ssh check_mailq check_sensors

check_clamd check_mrtg check_simap

check_cluster check_mrtgtraf check_smtp

check_dhcp check_mysql check_spop

check_dig check_mysql_query check_ssh

check_disk check_nagios check_ssmtp

check_disk_smb check_nntp check_swap

check_dns check_nntps check_tcp

check_dummy check_nrpe check_time

check_file_age check_nt check_udp

check_flexlm check_ntp check_ups

check_ftp check_ntp_peer check_users

check_http check_ntp_time check_wave

check_icmp check_nwstat negate

check_ide_smart check_oracle process_perfdata.pl

check_ifoperstatus check_overcr urlize

check_ifstatus check_ping utils.pm

check_imap check_pnp_rrds.pl utils.sh

check_ircd check_pop

check_jabber check_procs

首先我們定義commands

[root@node4 libexec]#cd /usr/local/nagios/etc/objects/

[root@node4 objects]#vim commands.cfg

define command {

command_name check_mysql

command_line $USER1$/check_mysql -H $HOSTADDRESS$ -u$ARG1$ -p $ARG2$

}

然后定義主機上的服務(wù)

[root@node4 objects]#vim localhost.cfg

define service{

use local-service,services-pnp

host_name localhost

service_description Mysql-server

check_command check_mysql!root!wiker

}

然后檢查語法

[root@node4 objects]#/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

……………………………………..

Total Warnings: 0

Total Errors: 0

然后重啟nagios服務(wù)

[root@node4 objects]#service nagios restart

Running configurationcheck...done.

Stopping nagios:done.

Starting nagios:done.

然后進入nagios界面，你就會看到我們加入的mysql服務(wù)
