nagois pnp集成装配

nagois pnp集成安装

一句话，程序员必须是万能的！

贴一篇文章，记录一下使用nagios监控Hadoop集群的过程，以免忘了。

安装过程（所有下载的文件都放在/usr/local/download）

#基础依赖

?写道# yum install httpd gcc glibc glibc-commom gd gd-devel
# yum install php php-gd -y
# yum -y install xinetd?

?写道# useradd nagios 创建nagios 用户
# passwd nagios 为nagios用户添加密码

# groupadd nagcmd 创建用户组用于Web接口执行外部命令
# usermod G nagcmd nagios 把nagios 用户加入nagcmd组
# usermod G nagcmd apache 把apache 用户加入nagcmd组?

安装nagios

?写道# mkdir download
# cd download
# wget http://cdnetworks-kr-2.dl.sourceforge.net/project/nagios/nagios-3.x/nagios-3.3.1/nagios-3.3.1.tar.gz

# tar zxf nagios-3.3.1.tar.gz
# cd nagios
# ./configure --with-command-group=nagcmd
# make all
# make install
# make install-init
# make install-commandmode
# make install-config
# make install-webconf?

修改/usr/local/nagios/etc/objects/contacts.cfg文件中联系人邮箱

添加认证用户nagiosadmin

?写道# htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin?

安装plugin

下载到download

?写道# wget http://cdnetworks-kr-1.dl.sourceforge.net/project/nagiosplug/nagiosplug/1.4.15/nagios-plugins-1.4.15.tar.gz
# tar zxf nagios-plugins-1.4.15.tar.gz
# cd nagios-plugins-1.4.15
# ./configure --with-nagios-user=nagios --with-nagios-group=nagios
# make && make install?

将nagios、httpd服务加入到系统服务，开机启动

?写道# chkconfig --add nagios
# chkconfig nagios on

# chkconfig --add httpd
# chkconfig httpd on?

验证配置文件&启动nagios httpd

?写道# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

# service nagios start
# service nagios start?

注：访问ip:8008/nagis/时，出现服务器内部错误问题，经查是cgi执行权限的原因，通过

一下命令解决：

?写道# chcon -R -t httpd_sys_content_t /usr/local/nagios/sbin/
# chcon -R -t httpd_sys_content_t /usr/local/nagios/share/
{
# chown nagios.nagios /usr/local/nagios/
# chown -R nagios.nagios /usr/local/nagios/libexec/
}?

安装nrpe

先安装ssl

?写道# yum install openssl-devel?

下载nrpe

?写道# wget http://prdownloads.sourceforge.net/sourceforge/nagios/nrpe-2.13.tar.gz
# tar zxf nrpe-2.13.tar.gz
# cd nrpe-2.13
# ./configure
# make all
# make install-plugin
# make install-daemon
# make install-daemon-config
# make install-xinetd?

修改commands.cfg 文件，最后加入一段

?写道# vim /usr/local/nagios/etc/objects/commands.cfg
# 'check_nrpe' command definition
define command{
command_namecheck_nrpe
command_line$USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}?

修改service ，添加一行

?写道# vim /etc/services
nrpe 5666/tcp #NRPE

# vim /etc/xinetd.d/nrpe
only_from = 127.0.0.1后加入 117....（不同地址间加空格）?

重启xinetd

?写道# service xinetd restart?

重启nrpe

?写道# pkill nrpe
# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
# /usr/local/nagios/libexec/check_nrpe -H 192.168.198.207?

测试本机连通性

?写道# /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1
NRPE v2.13?

测试本机负载

?写道# /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1 -c check_load
OK - load average: 0.06, 0.12, 0.17|load1=0.060;15.000;30.000;0; load5=0.120;10.000;25.000;0; load15=0.170;5.000;20.000;0;?

安装pnp4nagios

安装相关依赖

?写道# yum install libxml2 libxml2-devel cairo-devel pango-devel?

下载pnp

?写道wget http://cdnetworks-kr-2.dl.sourceforge.net/project/pnp4nagios/PNP-0.6/pnp4nagios-0.6.17.tar.gz?

下载rrdtool

?写道# wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.7.tar.gz

# tar zxf rrdtool-1.4.7.tar.gz
# cd rrdtool-1.4.7
# ./configure --prefix=/usr/local/rrdtool
# make && make install

# cd ..
# tar zxf pnp4nagios-0.6.17.tar.gz
# cd pnp4nagios-0.6.17
# ./configure --prefix=/usr/local/pnp4nagios --with-rrdtool=/usr/local/rrdtool/bin/rrdtool
（出现错误：configure: error: Perl Module Time::HiRes not available
解决办法：# yum install perl* -y
或者：# yum install perl-Time-HiRes
# yum install rrdtool-perl
）
# make all
# make install
# make install-webconf
# make install-config
# make install-init?

删除或者重命名install.php

?写道# cd /usr/local/pnp4nagios/share/
# mv install.php install.php.lock?

拷贝样例文件

?写道# cd /usr/local/pnp4nagios/etc/
# mv misccommands.cfg-sample misccommands.cfg
# mv nagios.cfg-sample nagios.cfg
# mv rra.cfg-sample rra.cfg
# cd pages/
# mv web_traffic.cfg-sample web_traffic.cfg
# cd ../check_commands/
# mv check_all_local_disks.cfg-sample check_all_local_disks.cfg
# mv check_nrpe.cfg-sample check_nrpe.cfg
# mv check_nwstat.cfg-sample check_nwstat.cfg
# service npcd restart

# cp /usr/local/download/pnp4nagios-0.6.17/contrib/ssi//* /usr/local/nagios/share/ssi/?

#回到解压目录下，复制鼠标悬停图标显示，预览绘图所需的文件

修改nagios 的模板文件，在对应的主机和服务定义字段里加入以下内容，

?写道# vim /usr/local/nagios/etc/objects/templates.cfg

# 'process-host-perfdata' command definition
define command{
command_name process-host-perfdata
command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl -d HOSTPERFDATA
}
# 'process-service-perfdata' command definition
define command{
command_name process-service-perfdata
command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl
}

# vi /usr/local/nagios/etc/nagios.cfg
process_performance_data=1
#将此变量值设为1
host_perfdata_command=process-host-perfdata
service_perfdata_command=process-service-perfdata
#取消这两项的注释?

编辑主机定义

在define host 的use中加入host-pnp

在define Service 的use中加入srv-pnp

重启nagios 可以看到图标

?写道# /etc/init.d/iptables status?

添加规则，然后保存一下就可以。

?写道# /sbin/iptables -I INPUT -p tcp --dport 5666 -j ACCEPT
# /etc/rc.d/init.d/iptables save?

如果还不管用就重启一下防火墙

# /etc/init.d/iptables restart

添加被监控主机：

安装nagios-plugin和nrpe（安装过程略）

?写道# vi /etc/services
添加
#add nrpe
nrpe 5666/tcp # nrpe

# vi /usr/local/nagios/etc/nrpe.cfg
修改
allowed_hosts=127.0.0.1, 117.40.133.17, 192.168.198.207?

主控机配置：

?写道# vi nagios.cfg
加一行
#add linux cfg
cfg_file=/usr/local/nagios/etc/objects/linux.cfg?

编辑/usr/local/nagios/etc/objects/linux.cfg的内容为

?写道define host{
use linux-server
host_name centos207
alias centos207
address 192.168.198.207
}
define service{
use generic-service
host_name centos207
service_description HTTP
check_command check_http
}
define service{
use generic-service
host_name centos207
service_description FTP
check_command check_ftp
}
define service{
use generic-service
host_name centos207
service_description SSH
check_command check_ssh
}
define service{
use generic-service
host_name centos207
service_description SMTP
check_command check_smtp
}
define service{
use generic-service
host_name centos207
service_description POP3
check_command check_pop
}

define service{
use generic-service
host_name centos207
service_description check-swap
check_command check_nrpe!check_swap
}
define service{
use generic-service
host_name centos207
service_description check-load
check_command check_nrpe!check_load
}
define service{
use generic-service
host_name centos207
service_description check-disk
check_command check_nrpe!check_sda1
}

define service{
use generic-service
host_name centos207
service_description zombie_procs
check_command check_nrpe!check_zombie_procs
}
define service{
use generic-service
host_name centos207
service_description check-users
check_command check_nrpe!check_users
}
define service{
use generic-service
host_name centos207
service_description total_procs
check_command check_nrpe!check_total_procs
}?
