nagios的安裝與配置

安裝前準備檢查環境

iptables -F

setenforce 0

#gcc環境 lamp環境和其他的一些 nagios 的依賴包

yum -y install gcc* yum -y install httpd mysql mysql-server mysql-devel php php-server glibc glibc-common *gd*

#添加nagios運行所需要的用戶和組

groupadd nagcmd 

useradd -G nagcmd nagios

usermod -G nagcmd apache

#編譯安裝nagios

mkdir /cdrom

cp -a /cdrom/* .

tar -xf nagios-3.3.1..tar.gz

cd nagios

./configure --with-commadn-group=nagcmd --enable-event-broker

make all && make install && make install-init make install-commandmode make install-config && make install-webconf

2.生成密碼文件

htpasswd -c /usr/local/nagios/etc/htpasswd.user nagiosadmin

service httpd restart

在瀏覽器中查看效果輸入用戶名和密碼

安裝插件管理器nagios-plugins

解壓編譯

tar -xf nagios-plugins-1.4.14.tar.gz

cd /root/nagios-plugins-1.4.14

./configure --with-nagios-user=nagios --wtih-nagios-group=nagios --with-mysql --enable-perl-modules

make && make install

配置并啟動nagios

chkconfig --add nagios

chkconfig nagios on

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

#此命令用來檢測語法

service nagios start

windows 主機的監控

安裝 NSCLIENt ++

服務器端設置windows監控

cd /usr/local/nagios

cd etc/

cd objects/

#進入nagios主目錄，啟用windows的支持

vim nagios.cf

vim /usr/local/nagios/etc/objects/contacts.cfg

#39  cfg_file=/usr/local/nagios/etc/objects/windows.cfg

vim /usr/local/nagios/etc/objects/contacts.cfg

#35     email    nagios@localhost報警郵箱根據實際改找個軟件最好然后用qq郵箱然后跟微信關聯qq號然后微信就可以知道報警了

檢測，并啟動nagios服務

/usr/local/nagios/bin/nagios -v /usr/local/ngios/etc/nagios.cfg

service nagios restart

Linux的監控

安裝gcc,openssl openssl-devel

yum -y install openssl openssl-devel

安裝插件管理器nagios-plugins

創建個nagios用戶,否則會報錯

useradd nagios

cd /root

tar -xf nagios-plugins-1.4.14.tar.gz

cd nagios-plugins-1.4.14

./configure --with-nagios-user=nagios --with-nagios-group=nagios

make all && make install

安裝nrpe確保openssl,openss-devel已經安裝

tar -xf nrpe-2.8.1.tar.gz

cd nrpe-2.8.1

./configure --enable-ssl --with-ssl-lib=/usr/lib

make all  

make install-plugin

make install-daemon

make install-daemon-config

vim /usr/local/nagios/etc/nrpe.cfg

allowed_hosts=192.168.121.1 127.0.0.1

/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

服務端裝

nagios-plugins

./configure --enable-ssl --with-ssl-lib=/usr/lib

make all

make install-plugin

cd /usr/local/nagios/etc/

cd objects/

ls

vim linux.cfg

vim cmmands.cfg

啟用自定義的liunx.cfg文件

vim /usr/local/nagios/etc/nagios.cfg

31# cfg_file=/usr/local/nagios/etc/objects/linux.cfg

檢測并啟用

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

service nagios restart

服務的監控

客戶端

yum -y install mysql mysql-server

service mysqld start

mysqladmin -uroot password '123123'

mysql -uroot -p

create database nagios;

grant selcet on nagios.* to nagios@'%' identifed by '123123';

select user,password,host from mysql.user;

服務端檢查一下是否能夠連接數據庫

/usr/local/nagios/libexec/check_mysql -H 192.168.121.1 -u nagios -d nagios -p 123123

vim mysql.cfg

啟動配置

vim /usr/local/nagios/etc/nagios.cfg

vim commadns.cfg

檢測啟動nagios

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

service nagios restart
