安装前准备检查环境
iptables -F
setenforce 0
#gcc环境 lamp环境和其他的一些 nagios 的依赖包
yum -y install gcc* yum -y install httpd mysql mysql-server mysql-devel php php-server glibc glibc-common *gd*
#添加nagios运行所需要的用户和组
groupadd nagcmd
useradd -G nagcmd nagios
usermod -G nagcmd apache
#编译安装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.生成密码文件
htpasswd -c /usr/local/nagios/etc/htpasswd.user nagiosadmin
service httpd restart
在浏览器中查看效果输入用户名和密码
安装插件管理器nagios-plugins
解压编译
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
配置并启动nagios
chkconfig --add nagios
chkconfig nagios on
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
#此命令用来检测语法
service nagios start
windows 主机的监控
安装 NSCLIENt ++
服务器端设置windows监控
cd /usr/local/nagios
cd etc/
cd objects/
#进入nagios主目录，启用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报警邮箱根据实际改找个软件最好然后用qq邮箱然后跟微信关联qq号然后微信就可以知道报警了
检测，并启动nagios服务
/usr/local/nagios/bin/nagios -v /usr/local/ngios/etc/nagios.cfg
service nagios restart
Linux的监控
安装gcc,openssl openssl-devel
yum -y install openssl openssl-devel
安装插件管理器nagios-plugins
创建个nagios用户,否则会报错
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
安装nrpe确保openssl,openss-devel已经安装
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
服务端装
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
启用自定义的liunx.cfg文件
vim /usr/local/nagios/etc/nagios.cfg
31# cfg_file=/usr/local/nagios/etc/objects/linux.cfg
检测并启用
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
service nagios restart
服务的监控
客户端
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;
服务端检查一下是否能够连接数据库
/usr/local/nagios/libexec/check_mysql -H 192.168.121.1 -u nagios -d nagios -p 123123
vim mysql.cfg
启动配置
vim /usr/local/nagios/etc/nagios.cfg
vim commadns.cfg
检测启动nagios
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
service nagios restart
