nagios监控

第一章 简介

1.nagios监控原理
1.Nagios 执行安装在它里面的 check_nrpe 插件，并告诉 check_nrpe 去检测哪些服务。
2.通过 SSL，check_nrpe 连接远端机子上的 NRPE daemon
3.NRPE 运行本地的各种插件去检测本地的服务和状态(check_disk,..etc)
4.最后，NRPE 把检测的结果传给主机端的 check_nrpe，check_nrpe 再把结果送到 Nagios状态队列中

第二章 Nagios安装

安装需要准备的软件包
nagios-3.4.3.gz
nagios-plugins-1.4.13.tar.gz
nrpe-2.8.1.tar.gz
gd-devel-2.1.0-7.5.1.x86_64.rpm

2.安装nagios

2.1 安装PHP环境

配置本地yum环境
cd /etc/yum.repos.d/
mkdir repo.bak
cp CentOS-* repo.bak/
rm -rf CentOS-*
vi aa.repo
[aa]
name=aa
baseurl=file:///mnt
gpgcheck=1

:wq 保存退出

挂载
mount /dev/dvd /mnt

rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-*

rpm -ivh gd-devel-2.1.0-7.5.1.x86_64.rpm --force --nodeps

yum install make gcc glibc glibc-common php gd gd-devel libpng libmng libjpeg zlib expect openssl openssl-devel -y

service httpd start


检测php安装是否成功
cd /var/www/html
建立php页面
vi index.php
<?php
phpinfo()
?>

:wq 保存退出

http://192.168.1.242

2.2 添加nagios软件用户和用户组

useradd nagios
groupadd nagcmd
usermod -G nagcmd apache
usermod -G nagcmd nagios

2.3安装和编译nagios

tar zxvf nagios-3.4.3.gz
cd nagios
# ./configure --prefix=/usr/local/nagios --with-command-group=nagcmd

编译Nagios程序包源码
# make all


安装二进制运行程序、初始化脚本、配置文件样本并设置运行目录权限
# make install

安装生成/usr/local/nagios/share的目录（即nagiosWEB访问界面的站点目录）
# make install-init

安装生成/etc/rc.d/init.d/nagios 启动脚本
# make install-config

安装生成/usr/local/nagios/etc下的nagios相关配置文件
# make install-commandmode

设定相应nagios工作目录的权限
# make install-webconf

安装Nagios的WEB配置文件到Apache的conf.d目录下

2.4 配置web接口

我们应该创建一个的用户用于Nagios的WEB接口登录。记住设置好的登录口令，一会儿你会用到它。
用户名：nagiosadmin
密码：herendh
htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
输入密码 herendh进行密码设置。


重启Apache服务以使设置生效。
service httpd reload
输入地址访问，此时nagios 什么也没有，需要安装下面的插件

将 Nagios和httpd设置为开机启动
chkconfig --add nagios
chkconfig nagios on
chkconfig --add httpd
chkconfig httpd on

3.安装nagios插件（服务器）nagios-plugins

tar zxvf nagios-plugins-1.4.13.tar.gz
cd nagios-plugins-1.4.13
./configure --with-nagios-user=nagios --with-nagios-group=nagcmd
make all
make install
service nagios reload
service httpd reload

4.安装nagios插件（服务器）nrpe

tar zxvf nrpe-2.8.1.tar.gz
cd nrpe-2.8.1
./configure
make all
make install-plugin

5.手动监控本机的监控对象

6.启动nagios

6.1 检测配置文件是否正确

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
如果没有报错，可以启动Nagios服务

service nagios start

6.2 打开nagios监控web页面

在web里面输入http://192.168.1.242/nagios

第三章 nagios添加邮件报警功能

1.解压并配置sendEmail插件

tar -zxvf sendEmail-v1.56.tar.gz
cp /sendEmail-v1.56/sendEmail /usr/local/bin/

2.测试sendEmail软件能否发送成功

/usr/local/bin/sendEmail -f [e-mail] -t [e-mail] -s smtp.163.com -u "nimei" -m "test1" -xu liudian456 -xp 789
显示发送ok就表明sendEmail能共正常发送邮件


3.定义发送sendEmail 的 command 命令
vi command.cfg
define command{
command_name notify-host-by-email
command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /usr/local/bin/sendEmail -f [e-mail] -t $CONTACTEMAIL$ -s smtp.163.com -u "** $NOTIFICATIONTYPE$ alert - $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" -xu liudian456 -xp 789
}
define command{
command_name notify-service-by-email
command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$\n" | /usr/local/bin/sendEmail -f [e-mail] -t $CONTACTEMAIL$ -s smtp.163.com -u "** $NOTIFICATIONTYPE$ alert - $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" -xu liudian456-xp 789
}

4.定义邮件联系人
vim /usr/local/nagios/etc/objects/contacts.cfg

define contactgroup{
contactgroup_name mail_admins
alias Nagios Administrators
members mail_lilin,nagiosadmin
}
define contact{
contact_name mail_lilin
use mail-contact
alias mail_lilin
email [e-mail]
}

5.定义邮件联系模板
define contact{
name mail-contact
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r,f,s
host_notification_options d,u,r,f,s
service_notification_commands notify-service-by-email
host_notification_commands notify-host-by-email
register 0 }

6.启动nagios 邮件服务功能
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
如果没有报错，可以启动Nagios服务
service nagios reload 现在有报警就会自动发送到[e-mail]这个联系的定义的邮箱了。可以加入多个邮箱，中间用”,”隔开。

第五章 nagios 图形化

Pnp4nagios图形化绘制nagios 数据

pnp4nagios是一个基于php和perl语言的强大工具，它可以通过process_perfdata.pl脚本调用rrdtool对nagios的性能数据进行分析并绘制成相应的性能图。所以在安装pnp4nagios之前，我们必须先安装php、perl、rrdtool。
rrdtool是Round Robin Database Tool的缩写。从功能上说，rrdtool可用于数据存储+数据展示。著名的网络流量绘图软件cacti和集群监控系统Ganglia使用的都是rrdtool。在数据存储方面，rrdtool采用“Round Robin”模式存储数据，即环状数据库。注意：rrdtool数据库文件后缀名为“.rrd”。

1.安装rrdtool

基础库安装
yum -y install gcc cairo-devel libxml2-devel pango-devel pango libpng-devel freetype freetype-devel libart_lgpl-devel php-gd
tar -xf rrdtool-1.5.4.tar.gz
cd rrdtool-1.5.4
./configure
make
make install

2.安装pnp4nagios

yum -y install perl-Time-HiRes
tar -xf pnp4nagios-0.6.25.tar.gz
cd pnp4nagios-0.6.25
./configure --with-rrdtool=/opt/rrdtool-1.5.4/bin/rrdtool --with-perl_lib_path=/opt/rrdtool-1.5.4/lib/perl/5.10.1/x86_64-linux-thread-multi/
make all
make install
make install-webconf
make install-config
make install-init

3.配置pnp4nagios

cd /usr/local/pnp4nagios/etc/
mv misccommands.cfg-sample misccommands.cfg
mv nagios.cfg-sample nagios.cfg
mv rra.cfg-sample rra.cfg
mv pages/web_traffic.cfg-sample pages/web_traffic.cfg
[root@localhost etc]#mv check_commands/check_all_local_disks.cfg-sample
check_commands/check_all_local_disks.cfg
[root@localhost etc]# mv check_commands/check_nrpe.cfg-sample
check_commands/check_nrpe.cfg
[root@localhost etc]# mv check_commands/check_nwstat.cfg-sample
check_commands/check_nwstat.cfg

4.启动pnp4nagios

/etc/init.d/npcd start
ps aux |grep npcd
chkconfig npcd on
chkconfig --list npcd

5.访问pnp4nagios

http://192.168.1.242/pnp4nagios/
输入nagios用户名和密码

最下方出现这句
Your environment passed all requirements. Remove or rename the
/usr/local/pnp4nagios/share/install.php file now.
执行
mv /usr/local/pnp4nagios/share/install.php /usr/local/pnp4nagios/share/install.php.bak

6.配置nagios

定义nagios配置文件
vi /usr/local/nagios/etc/nagios.cfg

定义模板
vi /usr/local/nagios/etc/objects/templates.cfg
define host {
name host-pnp
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_’ class=’tips’ rel=’/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=_HOST_
register 0
}
define service {

}
在heren.cfg、yingyong.cfg、oracle.cfg配置文件主机加入host-pnp ，服务加入srv-pnp
如下：
vi /usr/local/nagios/etc/objects/
define host{
use heren-server,host-pnp
host_name 192.168.1.240
alias 192.168.1.240
address 192.168.1.240
}

define service{
use heren-service,srv-pnp
host_name 192.168.1.240
service_description heren_url
check_command check_url_port!'192.168.1.240'!'http://192.168.1.240:80'!'nginx'!80
}




报错一:

1.缺少openssl openssl-devel
2.客户端配置文件，需要加入服务器IP
vi nrpe
allowed_hosts=127.0.0.1,192.168.1.242


报错二:

1..客户端配置文件需要加入服务端ip
vi /etc/xinetd.d/nrpe

报错三：
监控页面报错
DISK CRITICAL - /root/.gvfs is not accessible
客户端/root下执行
umount .gvfs
rm -rf .gvfs
