Icinga Installation

系统环境

OS： debian 5.0.8

Linux debian 2.6.26-2-amd64 #1 SMP Mon Sep 19 06:13:12 UTC 2011 x86_64 GNU/Linux

 

Icinga工作框架

说明：由于icinga是在nagios基础上延伸而来，是介于Nagios社区版和企业版间的产品，以下图也适用于Icinga 。

Prerequisites:

Apache

GCC compiler

C/C++ development libraries

GD development libraries

libdbi/libdbi-drivers, database like MySQL or PostgreSQL

 

安装步骤：（注意icinga和mysql数据库位于同一台机器上）

 

1.安装apache，gd开发库文件和gcc编译环境

debian:~#apt-get install apache2 build-essential libgd2-xpm-dev

 

2. 安装MySQL数据库

debian:~#apt-get install mysql-server mysql-client libdbi0 libdbi0-dev libdbd-mysql

 

3. 创建用户和组

debian:~# useradd -m icinga

debian:~# groupadd icinga-cmd

debian:~# usermod -a -G icinga-cmd icinga

修改apache启动用户为icinga ,并重启apache。

debian:/etc/apache2# vim envvars

export APACHE_RUN_USER=icinga

export APACHE_RUN_GROUP=icinga

debian:~# /etc/init.d/apache2 restart

 

4.从http://sourceforge.jp/projects/sfnet_icinga-cn/releases/下载汉化版icinga软件包进行编译安装。

debian:~#./configure --with-command-group=icinga-cmd --with-web-user=icinga --with-web-group=icinga --enable-idoutils

debian:~ #make install-commandmode 

debian:~ #make install-idoutils

启用idomod event broker 模块

debian:/usr/local/icinga/etc/modules#cp idoutils.cfg-sample idoutils.cfg

 

5. 配置mysql数据库

5.1创建icinga数据库并给予权限

debian:~# mysql -u root -p

mysql> create database icinga;

Query OK, 1 row affected (0.00 sec)

mysql> grant usage on *.* to 'icinga'@'localhost' identified by 'icinga' with MAX_QUERIES_PER_HOUR 0

    -> MAX_CONNECTIONS_PER_HOUR 0

    -> MAX_UPDATES_PER_HOUR 0;

Query OK, 0 rows affected (0.00 sec)

mysql> grant select,insert,update,delete,drop,create view on icinga.* to 'icinga'@'localhost';

Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

mysql> quit

Bye

5.2创建icinga表

mysql -u root -D icinga < icinga-cn-1.5.1/module/idoutils/db/mysql/mysql.sql

debian:~# mysql -u icinga -p icinga

mysql> use icinga;

mysql> show tables;

+----------------------------------------+

| Tables_in_icinga                       |

+----------------------------------------+

| icinga_acknowledgements                |

| icinga_commands                        |

| …………………………                   |

|                                        |

+----------------------------------------+

5.3编辑IDOUtils DB配置文件，确保含有如下内容:

debian:~# vim /usr/local/icinga/etc/ido2db.cfg

db_servertype=mysql

db_port=3306

db_user=icinga

db_pass=icinga

 

6. 配置icinga传统web界面(注：新的icinga web界面配置将在后面介绍)

debian:~/icinga/icinga-cn-1.5.1# make cgis

debian:~/icinga/icinga-cn-1.5.1# make install-cgis

debian:~/icinga/icinga-cn-1.5.1# make install-html

debian:~/icinga/icinga-cn-1.5.1# make install-webconf

这里创建web访问账号icingaadmin：

debian:~ #htpasswd -c /usr/local/icinga/etc/htpasswd.users icingaadmin

重启apache生效

debian:~ # /etc/init.d/apache2 reload

 

7. 编译安装nagios插件

从http://sourceforge.net/projects/nagiosplug/files/下载最新的nagios插件包进行安装。

debian:~/icinga/nagios-plugins-1.4.15#./configure --prefix=/usr/local/icinga \

> --with-cgiurl=/icinga/cgi-bin --with-htmurl=/icinga \

> --with-nagios-user=icinga --with-nagios-group=icinga

debian:~/icinga/nagios-plugins-1.4.15# make && make install

注：在编译过程中，可能会提示缺少包，导致某些功能无法使用，如snmp等，根据提示将相应的包安装后，再重新编译安装。

debian:~/icinga/nagios-plugins-1.4.15##apt-get install snmp libsnmp-dev

 

8.启动IDOUtils和Icinga

注意：IDOUtils必须先启动

debian:~# /etc/init.d/ido2db start

在启动icinga之前，使用如下命令对配置文件进行检查以确保无误；

debian:~#/usr/local/icinga/bin/icinga -v /usr/local/icinga/etc/icinga.cfg

debian:~ # /etc/init.d/icinga start

 

9. icinga基础安装已经完成，可访问http://yourip/icinga/

 

10. 安装PNP4Nagios附件组件，支持性能数据绘图功能

安装pnp4nagios之前，环境需要满足以下条件：

·  Perl >= 5.x

·  RRDtool >= 1.x, better 1.2 but not compulsory
Attention: installing RRDtool without a packet manager might lead to missing dejavu fonts. If you see graphs without text then this may be the cause.

·  Nagios >= 2.x or Icinga

·  Php

 

10.1安装rrdtool和php

debian:~/icinga# apt-get install rrdtool php5 php5-gd

从http://sourceforge.net/projects/pnp4nagios/files/下载最新的pnp4nagios软件包进行编译安装。

安装rrd 的perl模块

debian:~/icinga/pnp4nagios-0.6.16# apt-get install librrds-perl

debian:~/pnp4nagios-0.6.16#./configure --with-nagios-user=icinga --with-nagios-group=icinga

debian:~/icinga/pnp4nagios-0.6.16# make all && make fullinstall

 

10.2 启用icinga数据采集和绘图功能

debian:/usr/local/icinga/etc# vim icinga.cfg

process_performance_data=1

host_perfdata_file=/usr/local/pnp4nagios/var/host-perfdata

service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata

host_perfdata_file_template=DATATYPE::HOSTPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tHOSTPERFDATA::$HOSTPERFDATA$\tHOSTCHECKCOMMAND::$HOSTCHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$

service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$

host_perfdata_file_mode=a

service_perfdata_file_mode=a

host_perfdata_file_processing_interval=15

service_perfdata_file_processing_interval=15

host_perfdata_file_processing_command=process-host-perfdata-file

service_perfdata_file_processing_command=process-service-perfdata-file

以上内容均可从/usr/local/pnp4nagios/etc/nagios.cfg-sample文件中Bulk / NPCD mode部分获取。

注释：

process_performance_data设置为1，表示启用性能数据采集；

service_perfdata_file分别表示存放服务性能的临时数据文件；

service_perfdata_file_processing_interval处理性能文件时间间隔；

service_perfdata_file_processing_command处理性能文件调用的命令；

debian:/usr/local/icinga/etc# vim objects/commands.cfg 

在该文件中注释掉icinga默认的处理性能文件命令，新增“process-host-perfdata-file” 和“process-service-perfdata-file”指令，如下图所示：

重启icinga,让配置生效，注意重启服务之前，使用命令检查一下是否有错误。

 

10.3 配置pnp4nagios的数据采集模式

这里选择采用推荐的“Bulk + NPCD mode”模式进行性能数据采集绘图，其工作原理及流程如下图所示：

查看npcd.cfg文件，确认如下内容是否正确

debian:~# less /usr/local/pnp4nagios/etc/npcd.cfg

perfdata_spool_dir = /usr/local/pnp4nagios/var/spool/

perfdata_file_run_cmd = /usr/local/pnp4nagios/libexec/process_perfdata.pl

启动NPCD服务

debian:~#/usr/local/pnp4nagios/bin/npcd -d -f /usr/local/pnp4nagios/etc/npcd.cfg

 

10.4验证pnp4nagios安装

访问http://yourip/pnp4nagios, 出现500错误，查看apache日志，显示：

[Thu Jan 19 10:13:45 2012] [error] [client 192.168.22.240] (2)No such file or directory: Could not open password file: /usr/local/nagios/etc/htpasswd.users

这里显示为/usr/local/nagios/etc/htpasswd.users未找到，由于安装的是icinga,需要把nagios修改成icinga,重启apache即可。打开页面，显示所有测试项通过即可。

页面提示测试通过后，需要将/usr/local/pnp4nagios/share/install.php文件移走。

# mv /usr/local/pnp4nagios/share/install.php /usr/local/pnp4nagios/share/install.php_bakup

 

下载verify_pnp_config脚本进行配置验证

#wget http://verify.pnp4nagios.org/verify_pnp_config

执行脚本，如果没有“[CRIT]”，则表示配置正常；

10.5 将pnp4nagios图标显示于icinga web前端

在/usr/local/icinga/etc/objects目录下面新建文件pnp4nagios.cfg,其内容如下：

debian:/usr/local/icinga/etc/objects# cat pnp4nagios.cfg

define host{

        name                            host-pnp        ; The name of this host template

        action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_' class='tips' rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=_HOST_

        register                        0               ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!

        }

define service{

        name                            srv-pnp                 ; The 'name' of this service template

        action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$' class='tips' rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=$SERVICEDESC$

         register                        0                      ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL SERVICE, JUST A TEMPLATE!

        }

编辑模板文件templates.cfg，分别在主机和服务模板下面新增如下一行（红色标注）。

debian:/usr/local/icinga/etc/objects# vim templates.cfg

define host{

        name                            generic-host    ; The name of this host template

        use                             host-pnp

        notifications_enabled           1               ; Host notifications are enabled

        ………………………………

        }

define service{

        name                            generic-service         ; The 'name' of this service template

        use                             srv-pnp

        active_checks_enabled           1                       ; Active service checks are enabled

        passive_checks_enabled          1                       ; Passive service checks are enabled/accepted

             ……………………………

         }

注：增加上述指令后，icinga所有主机和服务都会自动在icinga监视页面出现pnp4nagios的图标。

在icinga主配置文件icinga.cfg,新增如下行即可

cfg_file=/usr/local/icinga/etc/objects/pnp4nagios.cfg

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 status-header.ssi,并确保该文件无可执行权限。

#cp ./pnp4nagios-0.6.16/contrib/ssi/status-header.ssi /usr/local/icinga/share/ssi/

拷贝pnp4nagios web页面配置文件config.php并修改该文件如下几处

debian:/usr/local/pnp4nagios/etc# vim config_local.php

$conf['nagios_base'] = "/icinga/cgi-bin";

 

debian:/usr/local/pnp4nagios/etc# cp config_local.php config.php

重启icinga服务，查看web页面（重启之前，确认配置无误），页面已经显示图标，点击查看，相关数据绘图已经展示(如图)，且支持鼠标悬停显示。

提示：可以在/usr/local/pnp4nagios/etc/config_local.php文件设置rrd绘画像素以及显示图像大小等。

 

11. 利用RRDtool Cache Deamon

rrdttool在处理大量的rrd文件时，会造成系统相对较高的I/O负载，利用rrdcaced，可以缓解对大量rrd文件多次随机写入的问题，它会缓存这些写入，批量进行更新，来减少disk I/O。注意检查RRDtool版本是否支持该特性。

 

安装rrdcached

# apt-get install  rrdcached

修改rrdcached启动脚本

debian:/etc/init.d# vim rrdcached

OPTS="-m 777 -s icinga -l unix:/tmp/rrdcached.sock "

OPTS="$OPTS -j /tmp -F"

#OPTS="$OPTS -b /var/lib/rrdcached/db/ -B"

 

启动rrdcached服务

#debian:~# /etc/init.d/rrdcached restart

# rrdcached -w 1800 -z 1800 -p /tmp/rrdcached.pid -j /tmp  -s icinga –F -m 777 -l unix:/tmp/rrdcached.sock

这里使用”-m 777”表示将/tmp/rrdcached.sock的权限设置为777,防止出现” ERROR Unable to connect to rrdcached: Permission denied”。

接下来设置pnp4nagios ，支持rrdcached 。

分别修改文件config_local.php 和 process_perfdata.cfg

debian:/usr/local/pnp4nagios/etc# vim config_local.php

# rrdcached support

# Use only with rrdtool svn revision 1511+

#

$conf['RRD_DAEMON_OPTS'] = 'unix:/tmp/rrdcached.sock';

 

debian:/usr/local/pnp4nagios/etc# vim process_perfdata.cfg

#

# Use only with rrdtool svn revision 1511+

#

RRD_DAEMON_OPTS = unix:/tmp/rrdcached.sock

注意这里sock路径和启动rrdcached服务的sock保持一致。

验证：
1>打开监控页面，数据绘图正常；

2>查看日志文件/usr/local/pnp4nagios/var/ perfdata.log, 无错误信息；

Install NagiosQL

NagiosQL是一个基于Web方式的Nagios配置管理工具,它使用PHP语 言开发,可运行在Apache下,后台使用Mysql数据库。同时,NagiosQL也是一个开源软件。

如果你使用过Nagios,那么你一定感知到了它 的强大监控功能,以及它的可扩展性。然而,它的监控配置信息都存放于文件中,配置和修改都需要手工编辑文件,这样十分不便,尤其当监控的内容增多时,问题就更加明显。NagiosQL就是一款解决此类问题的软件,它提供了可视化的配置环境（基于web方式）。

 

NagiosQL的原理图如下

         从图中不难看出NagiosQL的主要作用就是操作数据库和配置文件，其中包括将配置文件的信息写到数据库中，在数据库中修改Nagios的监控配置信息，并将数据库中存放的配置更新到文件中。用户可以通过NagiosQL提供的Web页面直观的修改配置。

 

安装部署：

Requirements

  Webserver e.g. Apache 1.x or above

  PHP 4.3 or above

  MySQL 4.1 or above

  Nagios 2 or above

  PEAR Module: HTML_Template_IT 1.1 or above

  PHP Extension: gettext

  PHP Extension: mysql

  PHP Extension: ftp

  Javascript enabled at your Webbrowser

 

环境说明

Icinga根目录：/usr/local/icinga

Icinga配置文件目录：/usr/local/icinga/etc

Icinga的用户和用户组：icinga|icinga

Apached启动用户和用户组： icinga|icinga

 

1. 安装php扩展模块

debian:~# apt-get install php-pear php5-gd php5-curl php5-mysql php-gettext

 

2. 安装HTML_Template_IT

debian:~# pear install HTML_Template_IT

 

3. 从www.nagiosql.org 下载nagiosql最新源码包，并解压到某个目录下面，这里指定为/usr/local/icinga/nagiosql

 

4. 修改属主及权限

debian:~#chown -R icinga:icinga /usr/local/icinga/nagiosql

修改config目录的访问权限，以使apache对其具有写权限

root@icinga:/usr/local/icinga/nagiosql# chmod -R 777 config/

 

5. 创建nagiosql配置文件存放目录，并修改权限

debian:~#cd /usr/local/icinga/nagiosql

debian:/usr/local/icinga/nagiosql# mkdir -p etc/{hosts,services,backup}

debian:/usr/local/icinga/nagiosql# mkdir -p etc/backup/{hosts,services}

debian:/usr/local/icinga/nagiosql# mkdir -p etc/import

debian:/usr/local/icinga/nagiosql# chown -R icinga:icinga etc

说明：

/usr/local/icinga/nagiosql/etc                                    -> Common configuration files

/usr/local/icinga/nagiosql/etc/hosts            -> Host configuration files

/usr/local/icinga/nagiosql/etc/service          -> Service configuration files

/usr/local/icinga/nagiosql/etc/backup/         -> Backups of the common configuration files

/usr/local/icinga/nagiosql/etc/backup/hosts          -> Backups of the host configuration files

/usr/local/icinga/nagiosql/etc/backup/services   -> Backups of the service configuration files

 

6. 修改apache的httpd.conf文件，重启apache服务

debian:/etc/apache2/conf.d# vim nagiosql.conf

# SAMPLE CONFIG SNIPPETS FOR APACHE WEB SERVER

 

Alias /nagiosql "/usr/local/icinga/nagiosql"

 

<Directory "/usr/local/icinga/nagiosql">

        AllowOverride None

        Order allow,deny

        Allow from all

</Directory>

 

7. 通过浏览器进入如下地址http://<IP>/nagiosql，其中IP是apache服务主机的IP地址。

按照界面上的提示进行安装即可，最后删除install目录，完成配置。以下图为登录页面。

 

8. 进入NagiosQL，首先要基础配置，设置配置文件的位置，进入Administration -> Domains，编辑localhost。如下图所示：

 

9. 修改icinga.cfg文件（红色部分为新增），对配置文件检查并重启icinga服务。

debian:/usr/local/icinga/etc# vim icinga.cfg

# You can specify individual object config files as shown below:

#cfg_file=/usr/local/icinga/etc/objects/pnp4nagios.cfg

# You can also tell Icinga to process all config files (with a .cfg

# extension) in a particular directory by using the cfg_dir

# directive as shown below:

#cfg_dir=/usr/local/icinga/etc/servers

#cfg_dir=/usr/local/icinga/etc/printers

#cfg_dir=/usr/local/icinga/etc/switches

#cfg_dir=/usr/local/icinga/etc/routers

# Definitions for broker modules like idoutils.cfg

cfg_dir=/usr/local/icinga/etc/modules

 

10. 配置好路径后，将Icinga的配置文件导入到数据库中，Tools -> Data import，选择文件Import。在Supervision -> Hosts下可看到刚导入的配置，可进行编辑并写回文件文件中。

Install Icinga-Web

 

1. 安装php扩展模块,其它php模块如php-gd,php-pear,php5,php5-mysql等已经安装；

debian:~# apt-get install php5-xmlrpc php5-xsl  php5-ldap  phpunit  phpunit2

debian:~# pear install PHP_CodeSniffer

 

2. 从http://sourceforge.jp/projects/sfnet_icinga-cn/releases/下载汉化版icinga-cn-web-1.5.2.tar.bz2进行编译安装；

debian:~/icinga-cn-web-1.5.2# ./configure --prefix=/usr/local/icinga-web --with-web-user=icinga --with-web-group=icinga

debian:~/icinga-cn-web-1.5.2# make install

debian:~/icinga-cn-web-1.5.2# make install-apache-config

 

3. 测试php模块依赖性；

debian:~/icinga-cn-web-1.5.2# make testdeps

/usr/bin/php bin/testdeps.php

Icinga-web dependencies (running 23 test)

PHP (core) tests

        1/23 Test php version >= 5.2.3 (REQUIRED) ... (version 5.2.6-1+lenny13 >= 5.2.3) OK

All over result: PASS (required 12/12, optional 10/11, all 22/23, time 0.04s)

Exit (status=0)

 

4. 创建相应的数据库用户和DB，并初始化;

Icinga-Web 将会创建自己的数据库，默认为icinga_web；

mysql> GRANT USAGE ON *.* TO 'icinga_web'@'localhost' IDENTIFIED BY 'icinga_web';

Query OK, 0 rows affected (0.00 sec)

mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER, INDEX ON icinga_web.* TO 'icinga_web'@'localhost';

Query OK, 0 rows affected (0.01 sec)

mysql> CREATE DATABASE icinga_web;

Query OK, 1 row affected (0.00 sec)

mysql> GRANT USAGE ON *.* TO 'icinga_web'@'localhost' IDENTIFIED BY 'icinga_web' WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0;

Query OK, 0 rows affected (0.00 sec)

mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER, INDEX ON icinga_web.* TO 'icinga_web'@'localhost';

Query OK, 0 rows affected (0.00 sec)

 

debian:~/icinga-cn-web-1.5.2# make db-initialize

 

5. 配置Icinga-web;

说明：Icinga-web将会首先读取位于/usr/local/icinga-web/etc/conf.d/ databases.xml 的数据库配置文件，升级时改文件不会被覆盖，这样避免丢失以前的配置。Icinga new web将会使用icinga-web数据库，这里有另一个icinga数据库,是供ido2db使用；以下两个文件保持默认即可；

debian:/usr/local/icinga-web# grep mysql app/config/databases.xml

<ae:parameter name="dsn">mysql://icinga_web:icinga_web@localhost:3306/icinga_web</ae:parameter>

<ae:parameter name="dsn">mysql://icinga:icinga@localhost:3306/icinga</ae:parameter>

文件access.xml 定义icinga命令路径等；

debian:/usr/local/icinga-web/etc/conf.d# grep icinga access.xml

<resource name="icinga_objects">/usr/local/icinga/etc/objects</resource>

<resource name="icinga_cfg">/usr/local/icinga/etc/icinga.cfg</resource>

<resource name="icinga_pipe">/usr/local/icinga/var/rw/icinga.cmd</resource>

<resource name="icinga_service">/etc/init.d/icinga</resource>

<resource name="icinga_bin">/usr/local/icinga/bin/icinga</resource>

注意：修改以上文件后，需要清除配置缓存。

debian:~# /usr/local/icinga-web/bin/clearcache.sh

 

5. 配置apache;

启用mod_rewrite

debian:~# a2enmod rewrite

验证：

debian:~# ls -ltr /etc/apache2/mods-enabled/rewrite.load

lrwxrwxrwx 1 root root 30 01-23 17:12 /etc/apache2/mods-enabled/rewrite.load -> ../mods-available/rewrite.load

切换到目录/usr/local/icinga-web/pub，修改.htaccess文件，调整RewriteBase指令所指向的目录，这里默认为/icinga-web/;

debian:/usr/local/icinga-web/pub# grep RewriteBase  .htaccess

RewriteBase /icinga-web

检查由make install-apache-config命令生成的/etc/apache2/conf.d/icinga-web.conf 配置是否正确；

最后清除缓存并重启apache服务。

debian:~# /usr/local/icinga-web/bin/clearcache.sh

debian:~# /etc/init.d/apache2 restart

使用浏览器访问http://yourip/icinga-web/ ,初始用户和密码分别为root/password; 

6. 将PNP4Nagios整合到Icinga-Web;

首先需要安装PNP4Nagios，关于PNP4Nagios安装，见前面描述。Pnp4naigos被安装在/usr/local/pnp4nagios/目录下。

修改配置文件config.php

debian:/usr/local/pnp4nagios/etc# vim config.php

$conf['nagios_base'] = "/icinga/cgi-bin";

拷贝pnp4nagios 主机和服务模板xml文件(适用于icinga-web version 1.5及以上版本)

debian:~/icinga-cn-web-1.5.2/contrib/PNP_Integration#cp templateExtensions/pnp-host-extension.xml /usr/local/icinga-web/app/modules/Cronks/data/xml/extensions

debian:~/icinga-cn-web-1.5.2/contrib/PNP_Integration# cp templateExtensions/pnp-service-extension.xml /usr/local/icinga-web/app/modules/Cronks/data/xml/extensions

最后清除缓存。

debian:~# /usr/local/icinga-web/bin/clearcache.sh
