Nagios 安装 部署 说明
Nagios是一个用来监控主机、服务和网络的开放源码软件，可以在发生故障时发送报警短信和邮件,只要Nagios监控的对象发生故障，系统就会自动发送短信到手机上。所以应用十分广泛。
Nagios is an open source host, service and.network monitoring program. Who uses it? Lots of people, including many big companies and organizations。
一． 相关包的下载：
可以先下载到windows在通过mount 挂载到redhat上，也可以通过wget 直接下载:
下载地址：http://www.nagios.org/download
Nagios Core OSS consists of various Open Source components that provide the foundation for rock-solid IT infrastructure monitoring. Download all the components you need to get started.
Step 1 - Get Nagios Core
Required. Contains the core monitoring application and web interface.
# ./wget http://ncu.dl.sourceforge.net/project/nagios/nagios-3.x/nagis-3.2.1/nagios-3.2.1.tar.gz
Step 2 - Get Nagios Plugins
Also Required. Allows you to monitor services, applications, metrics, and more.
# ./wget http://ncu.dl.sourceforge.net/project/nagiosplug/nagiosplug/.4.14/nagios-plugins-1.4.14.tar.gz
Step 3 - Get Nagios Addons
Trick out your Nagios install by extending its capabilities with hundreds of community-contributed addons.
# ./wget http://ncu.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-212/nrpe-2.12.tar.gz
# ./wget http://ncu.dl.sourceforge.net/project/nagios/nsca-2.x/nsca-27.2/nsca-2.7.2.tar.gz
# ./wget http://ncu.dl.sourceforge.net/project/nagios/ndoutils-1.x/ndutils-1.4b9/ndoutils-1.4b9.tar.gz
NRPE allows you to remotely execute Nagios plugins on other Linux/Unix machines. This allows you to monitor remote machine metrics (disk usage, CPU load, etc.). NRPE can also communicate with Windows agent addons like NSClient++, so you can check metrics on remote Windows machines as well.
NSCA allows you to integrate passive alerts and checks from remote machines and applications with Nagios. Useful for processing security alerts, as well as deploying redundant and distributed Nagios setups.
NDOUtils allows you to export current and historical data from one or more Nagios instances to a MySQL database. Experimental/beta at this point in time, but several community addons use this as one of their data sources.
监控windows 需要NSClient，下载：
http://sourceforge.net/projects/nscplus/
windows上客户端的配置请参考blog：
How To Monitor Remote Windows Machine Using Nagios on Linux
http://blog.csdn.net/tianlesoftware/archive/2010/03/25/5417814.aspx
监控Linux，需要安装NRPE 包 和 plugins 程序。
Web 服务器：

二． Nagios 安装
2.1 linux 下软件安装步骤
1）解压：Tar zxvf *.gz
2）运行: ./configure，会生成makefile文件。
3）编译: ./make all
4）安装软件: ./make install，
2.2 安装顺序：
1). 安装Nagios
./configure
... ...
Creating sample config files in sample-config/ ...
*** Configuration summary for nagios 3.2.1 03-09-2010 ***:
General Options:
-------------------------
Nagios executable: nagios
Nagios user/group: nagios,nagios
Command user/group: nagios,nagios
Embedded Perl: no
Event Broker: yes
Install ${prefix}: /usr/local/nagios
Lock file: ${prefix}/var/nagios.lock
Check result directory: ${prefix}/var/spool/checkresults
Init directory: /etc/rc.d/init.d
Apache conf.d directory: /etc/httpd/conf.d
Mail program: /bin/mail
Host OS: linux-gnu
Web Interface Options:
------------------------
HTML URL: http://localhost/nagios/
CGI URL: http://localhost/nagios/cgi-bin/
Traceroute (used by WAP): /bin/traceroute
Review the options above for accuracy. If they look okay,
type 'make all' to compile the main program and CGIs.
--创建用户和组
#groupadd nagios
#useradd -g nagios nagios
#passwd nagios
[root@Dave nagios-3.2.1]# cd ./base
[root@Dave base]# pwd
/nagios/nagios-3.2.1/base
[root@Dave base]#./make all
If the main program and CGIs compiled without any errors, you
can continue with installing Nagios as follows (type 'make'
without any arguments for a list of all possible options):
make install
- This installs the main program, CGIs, and HTML files
make install-init
- This installs the init script in /etc/rc.d/init.d
make install-commandmode
- This installs and configures permissions on the
directory for holding the external command file
make install-config
- This installs *SAMPLE* config files in /usr/local/nagios/etc
You'll have to modify these sample files before you can
use Nagios. Read the HTML documentation for more info
on doing this. Pay particular attention to the docs on
object configuration files, as they determine what/how
things get monitored!
make install-webconf
- This installs the Apache config file for the Nagios
web interface
根据上面的提示，在make install 的时候我们要分别执行：
make install
make install-init
make install-commandmode
make install-config
make install-webconf
验证程序是否被正确安装。切换目录到安装路径（这里是/usr/local/nagios）,看是否存在 etc、bin、 sbin、 share、 var这五个目录，如果存在则可以表明程序被正确的安装到系统了。
五个目录功能的简要说明：
| bin |
Nagios执行程序所在目录，这个目录只有一个文件nagios |
| etc |
Nagios配置文件位置，初始安装完后，只有几个*.cfg-sample文件 |
| sbin |
Nagios Cgi文件所在目录，也就是执行外部命令所需文件所在的目录 |
| Share |
Nagios网页文件所在的目录 |
| Var |
Nagios日志文件、spid 等文件所在的目录 |
|
|
|
2). 插件安装：
./configure
Make
Make install
安装完成后，将在目录/usr/local/nagios生成目录libexec目录（里面有很多文件)。
3). 安装web服务器apache
Web服务不是nagios所必须的，但是如果nagios没有web，只有通过查看nagios的日志来判断状态。
在unix/linux世界，apache是web服务器的首选对象，其下载网站为www.apache.org 。建议下载源码。因为我们不需要很复杂的web功能，因此简单的执行一下几个步骤就可以正确的把apache安装到系统：
1、 解包、配置：tar zxvf httpd-*.tar.gz ; ./configure –prefix=/usr/local/apache 。
2、 编译安装： make ; make install 。
安装完成后，执行命令 ./usr/local/apache/bin/apachectl –t 检查一下apache是否正确安装
4) -Get Nagios Addons。 在待监控的机子上安装NRPE for linux. NSClient for windows 这个在后面配置的时候有说明
./configure
Make
Make install
三．Nagios 配置前的准备
最主要的工作是创建nagios用户及其属组，让nagios的运行用户为nagios而不是root。再把目录/usr/local/nagios的属主设置为nagios，以保证系统的安全。Nagios可以以root用户运行，但并不推荐这样做。用下面的步骤来完成上述过程：
1、添加系统帐户nagios, 在安装Nagios的时候，已经做过这一步.
--创建用户和组
#groupadd nagios
#useradd -g nagios nagios
#passwd nagios
在实际的运用场景，nagios用户并没有必要作为系统用户来登录linux系统，因此可以不必设置nagios的用户密码，甚至可以把nagios用户的登录shell设置成/bin/false。
2、更改目录属组：chown –R nagios.nagios /usr/local/nagios 。请注意，有的unix/linux的版本用户和属组分隔符号不是“.”,可能会是这样的形式 chown -R nagios:nagios /usr/local/nagios 。
3、sendmail。我们需要使用sendmail来发送故障报警信息，所以这个包必须能够正常工作。 现在一般的Linux系统都自带了sendmail，我们只需要启动sendmail即可。
4、手机短信发送工具。
如果公司有发送短信的平台，那么直接调用就可以了，如果没有，我们可以让手机接收邮件，或者使用飞信来发送。
四． Nagios 的配置
4.1 Apache 配置：
A sample Apache config file snippet is created when you run the configure script - you can find the sample config file (named httpd.conf) in the sample-config/ subdirectory of the Nagios distribution. You will need to add the contents of this file to your Apache configuration files before you can access the Nagios web interface. The instructions found below detail how to manually add the appropriate configuration entries to Apache.
Configure Aliases and Directory Options For The Web Interface
First you'll need to create appropriate entries for the Nagios web interface (HTML and CGIs) in your web server config file. Add the following snippet to your web server configuration file (i.e. httpd.conf), changing it to match any directory differences on your system.
ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin
<Directory "/usr/local/nagios/sbin">
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</Directory>
Alias /nagios /usr/local/nagios/share
<Directory "/usr/local/nagios/share">
Options None
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</Directory>
Note: The default Nagios installation expects to find the HTML files and CGIs at http://yourmachine/nagios/ and http://yourmachine/nagios/cgi-bin/, respectively. These locations can be changed using the --with-htmurl and --with-cgiurl options in the configure script.
Important! If you are installing Nagios on a multi-user system, you may want use CGIWrap to provide additional security between the CGIs and the external command file. If you decide to use CGIWrap, the ScriptAlias you'll end up using will most likely be different from that mentioned above. More information on doing this can be found here.
Restart The Web Server
Once you've finished editing the Apache configuration file, you'll need to restart the web server with a command like this...
/etc/rc.d/init.d/httpd restart
Configure Web Authentication
Once you have installed the web interface properly, you'll need to specify who can access the Nagios web interface.
If you haven't done so already, you'll need to add the appropriate entries to your web server config file to enable basic authentication for the CGI and HTML portions of the Nagios web interface. Instructions for doing so can be found here.
Now that you've configured your web server to require authentication for the Nagios web interface, you'll need to specify who has access. This is done by using the htpasswd command supplied with Apache.
Running the following command will create a new file called htpasswd.users in the /usr/local/nagios/etc directory. It will also create an username/password entry for nagiosadmin. You will be asked to provide a password that will be used when nagiosadmin authenticates to the web server.
htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
Continue adding more users until you've created an account for everyone you want to access the CGIs. Use the following command to add additional users, replacing <username> with the actual username you want to add. Note that the -c option is not used, since you already created the initial file.
htpasswd /usr/local/nagios/etc/htpasswd.users <username>
Okay, so you're done with the first part of what needs to be done. At this point you should be prompted for a username and password if you point your web browser to the Nagios web interface. If you have problems getting user authentication to work at this point, read your webserver documentation for more info.
Verify Your Changes
Don't forget to check and see if the changes you made to Apache work. You should be able to point your web browser at http://yourmachine/nagios/ and get the web interface for Nagios. The CGIs may not display any information, but this will be remedied once you configure everything and start Nagios.

http://nagios.sourceforge.net/docs/2_0/installweb.html
4.2 Nagios 的配置文件
Nagios在安装完会默认生成一些简单的配置文件，但是如果要满足我们需求我们还需要自己添加一些文件。
Objects are all the elements that are involved in the monitoring and notification logic. Types of objects
include:
Services
Service Groups
Hosts
Host Groups
Contacts
Contact Groups
Commands
Time Periods
Notification Escalations
Notification and Execution Dependencies
1）/usr/local/nagios/etc/nagios.cfg。 -- Nagios 的主要配置文件
# You can specify individual object config files as shown below:
cfg_file=/usr/local/nagios/etc/objects/commands.cfg
cfg_file=/usr/local/nagios/etc/objects/contacts.cfg
cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg
cfg_file=/usr/local/nagios/etc/objects/templates.cfg
# Definitions for monitoring the local (Linux) host
cfg_file=/usr/local/nagios/etc/objects/localhost.cfg
# Definitions for monitoring a Windows machine
cfg_file=/usr/local/nagios/etc/objects/windows.cfg
# Definitions for monitoring a router/switch
#cfg_file=/usr/local/nagios/etc/objects/switch.cfg
# Definitions for monitoring a network printer
#cfg_file=/usr/local/nagios/etc/objects/printer.cfg
里面还有与是否发送警告的相关配置参数. 默认都是启动的。
先注释掉相关的控制文件，在修改对应的的文件。
Nagios 的配置修改之后要
[root@Dave objects]# service nagios restart
#配置机器启动时自动启动Nagios
#chkconfig nagios on
2） /usr/local/nagios/etc/cgi.cfg
cgi.cfg 内容如下：
main_config_file=/usr/local/nagios/etc/nagios.cfg
physical_html_path=/usr/local/nagios/share
url_html_path=/nagios
use_authentication=1
authorized_for_system_information=nagiosadmin
authorized_for_configuration_information=nagiosadmin
authorized_for_system_commands=nagiosadmin
authorized_for_all_services=nagiosadmin
authorized_for_all_hosts=nagiosadmin
authorized_for_all_service_commands=nagiosadmin
authorized_for_all_host_commands=nagiosadmin
#authorized_for_read_only=user1,user2
如果有多个用户，用逗号隔开, 这些用户就是在apache配置中添加的：
htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
3） /usr/local/nagios/etc/objects/timeperiods.cfg
define timeperiod{
timeperiod_name 24x7
alias 24 Hours A Day, 7 Days A Week
sunday 00:00-24:00

tuesday 00:00-24:00
wednesday 00:00-24:00
thursday 00:00-24:00
friday 00:00-24:00
saturday 00:00-24:00
}
define timeperiod{
timeperiod_name none
alias No Time Is A Good Time
}
define timeperiod{
name us-holidays
timeperiod_name us-holidays
alias U.S. Holidays
january 1 00:00-00:00 ; New Years
monday -1 may 00:00-00:00 ; Memorial Day (last Monday in May)
july 4 00:00-00:00 ; Independence Day
monday 1 september 00:00-00:00 ; Labor Day (first Monday in Sep tember)
thursday -1 november 00:00-00:00 ; Thanksgiving (last Thursday in November)
december 25 00:00-00:00 ; Christmas
}
define timeperiod{
timeperiod_name 24x7_sans_holidays
alias 24x7 Sans Holidays
use us-holidays ; Get holiday exceptions from ot her timeperiod
sunday 00:00-24:00
monday 00:00-24:00
tuesday 00:00-24:00
wednesday 00:00-24:00
thursday 00:00-24:00
friday 00:00-24:00
saturday 00:00-24:00
}
4) /usr/local/nagios/etc/objects/Commands.cfg
该文件保存了写如发送邮件的命令，可以根据自己的需求进行扩展。
# 'notify-host-by-email' command definition
define command{
command_name notify-host-by-email
command_line /usr/bin/printf "%b" "***** Nagios *****/n/nNotification
Type: $NOTIFICATIONTYPE$/nHost: $HOSTNAME$/nState: $HOSTSTATE$/nAddress: $HOSTA
DDRESS$/nInfo: $HOSTOUTPUT$/n/nDate/Time: $LONGDATETIME$/n" | /bin/mail -s "** $
NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$
}
# 'notify-service-by-email' command definition
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:

Info:/n/n$SERVICEOUTPUT$" | /bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert:
$HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
5) /usr/local/nagios/etc/objects/contacts.cfg 文件， 该文件保存是接收报警联系人的信息
define contact{
contact_name Dave
use generic-contact
alias Dave
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r
host_notification_options d,u,r
service_notification_commands notify-service-by-email
host_notification_commands notify-host-by-email
email tianlesoftware@vip.qq.com
}
define contact{
contact_name nagiosadmin
use generic-contact
alias Nagios Admin
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r
host_notification_options d,u,r
service_notification_commands notify-service-by-email
host_notification_commands notify-host-by-email
email tianlesoftware@qq.com
}
define contactgroup{
contactgroup_name admins
alias Nagios Administrators
members nagiosadmin,Dave
}
上面的文件定义了2个联系人，如果有更多联系人的话，照这个格式在后面追加即可。在contactgroup里, 多个成员之间用逗号做分界符，如果有更多的联系组，就依相同的格式在文件中追加余下的组。
Table 1. Service notification options
| Notify on transition |
Option |
| WARNING service states |
w |
| UNKNOWN service states |
u |
| CRITICAL service states |
c |
| Service RECOVERY states |
r |
| Send NO service notifications |
n |
Table 2. Host notification options
| Notify on transition |
Option |
| DOWN host states |
d |
| UNREACHABLE host states |
u |
| HOST RECOVERIES (return to UP state) |
r |
| Send NO host notifications |
n |
7 ) /usr/local/nagios/etc/objects/windows.cfg 监控windows的客户端及监控配置文件
这些文件的参数可以可以参考templates.cfg 文件。 Windows 和Linux 的格式有些出入， 这点要注意。

check_command check_nt!PROCSTATE!-d SHOWALL -l Explorer.exe
}
如果有多台windows PC, 只需要把相关的属性复制一下，然后把host_name改成对应PC的就可以了。
在安装windows 客户端的时候NSClient 参数也需要做一些，具体参考blog：

如果有多台Linux, 只需要把相关的属性复制一下，然后把host_name改成对应PC的就可以了。Linux的客户端需要安装NRPE 包 和 plugins 程序。
9) 验证：
运行程序/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg来检查所有配置文件的正确性。如果运行完毕将在输出尾部出现
Total Warnings: 0
Total Errors: 0
则配置正确，如果有错误，提示也是很明显。 修改过来即可。
如：
Error: Invalid hostgroup object directive 'membes'.
Error: Could not add object property in file '/usr/local/nagios/etc/objects/windows.cfg' on line 58.
Error processing object config files!

1）在commads.cfg 文件中添加2个选项
define command {
command_name notify-host-by-fetion
command_line /usr/bin/fetion --mobile=13865997399 --pwd=woshidmm --to=$CONTACTPAGER$ --msg-utf8="Host $HOSTSTATE$ alert for $HOSTNAME$! on '$LONGDATETIME$'" $CONTACTPAGER$
}
define command {
command_name notify-service-by-fetion
command_line /usr/bin/fetion --mobile=13865997399 --pwd=woshidmm --to=$CONTACTPAGER$ --msg-utf8="$HOSTADDRESS$ $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ on $LONGDATETIME$" $CONTACTPAGER$
}
2） 在contacts.cfg 的联系人中添加 pager 选项, 和相关命令的调用。
define contact{
contact_name nagiosadmin
use generic-contact
alias Nagios Admin
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r
host_notification_options d,u,r
service_notification_commands notify-service-by-email,notify-service-by-fetion
host_notification_commands notify-host-by-email,notify-host-by-fetion
email [email protected]
pager 13888888888,13888888888
}
重启Nagios： service nagios reload
启动apache 服务：
[root@Dave bin]# service httpd start
启动nagios 服务：
[root@Dave bin]# service nagios start
4.4 测试：
在IE中输入地址： http://ip/nagios 就可以看到管理界面了。 如果有更多的服务器，建议使用mysql数据来管理监控对象。
以上内容是Nagios 的简单的安装部署应用， 如果说要监听打印机，交换机之类的，还需要安装对应的插件。 等以后有空的时候在慢慢研究了. 如果感兴趣的也可以研究下Nagios 的文档。
