nagios运用飞信实现短信报警监控服务器

[root@localhost php-5.2.10]# ./configure --prefix=/usr/local/php \
> --with-apxs2=/usr/local/apache/bin/apxs
[root@localhost php-5.2.10]# make && make install
[root@localhost php-5.2.10]# cp php.ini-dist /usr/local/lib/php.ini
[root@localhost php-5.2.10]# vi /usr/local/apache/conf/httpd.conf请

为了配置文件的工整，在配置文件的相关地方加入如下配置：

LoadModule php5_module modules/libphp5.so （如果有，不用加）
AddType application/x-httpd-php .php .html
找到DirectoryIndex index.html
改为： DirectoryIndex index.php index.html
在最后加入nagios的访问目录：
ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin
<Directory "/usr/local/nagios/sbin">
AuthType Basic
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
</Directory>
Alias /nagios /usr/local/nagios/share
<Directory "/usr/local/nagios/share">
AuthType Basic
Options None
AllowOverride None
Order allow,deny
Allow from all
</Directory> 请输入内容

(3) nagios的安装

为了支持Nagios安装完后status map,trend等完全显示，需要gd库的支持，首先看一下gd与gd-devel有没有安装

[root@localhost php-5.2.10]# rpm -qa|grep gd

gdb-6.5-37.el5

libgdiplus-1.2.5-1.el5.centos

gd-2.0.33-9.4.el5_1.1

gdbm-1.8.0-26.2.1

sysklogd-1.4.1-44.el5

libgdiplus-devel-1.2.5-1.el5.centos

gd-devel-2.0.33-9.4.el5_1.1

如果没有，请拿出光盘安装上，或者用yum -y install gd*安装也可

[root@localhost nagios-3.1.2]# useradd nagios

[root@localhost nagios-3.1.2]# ./configure --prefix=/usr/local/nagios \

> --with -gd-lib=/usr/lib --with-gd-inc=/usr/include --with-nagios-user=nagios \

> --with-nagios-group=nagios

[root@localhost nagios-3.1.2]# make all

[root@localhost nagios-3.1.2]# make install

[root@localhost nagios-3.1.2]# make install-init

[root@localhost nagios-3.1.2]# make install-commandmode

[root@localhost nagios-3.1.2]# make install-config

(4) nagios-plugin的安装

[root@localhost nagios-plugins-1.4.13]# ./configure --prefix=/usr/local/nagios

[root@localhost nagios-plugins-1.4.13]# make && make install

(5) 飞信机器人的安装

在安装飞信之前需要在/usr/lib目录下加上libACE库文件，以便使飞信能够正常使用

[root@localhost src]# tar zxvf library_linux.tar.gz

[root@localhost src]# mv libACE* libcrypto.so.0.9.8 libssl.so.0.9.8 /usr/lib

好了，现在来正式安装飞信

[root@localhost src]# tar zxvf fetion20090406003-linux.tar.gz

[root@localhost src]# mv install /usr/local/fetion

[root@localhost src]# chmod -R 755 /usr/local/fetion

[root@localhost src]# chown -R nagios:nagios /usr/local/fetion

测试飞信能否成功发送短信（发送对象需是自己飞信好友）：

[root@localhost src]# /usr/local/fetion/fetion --mobile=137*** --pwd=*** \

> --to=136*** --msg-utf8="test"

如果136***能成功收到137***的短信就是正常的哟，如果不能成功看日志。

3、nagios的配置

首先讲一下，我建有host(主机），hostgroup(主机组），contact（联系人），contactgroup(联系人组），分别讲一下它们的相关情况：

host包含：TH-02,VH-178,VH-132,MH-110,MH-13

hostgroup包含：TG(别名：testgroup) , VG(别名：virtualgroup),MG(别名：maintaingroup)；TG包括主机：TH-02，VG包括主机：VH-132，VH-178，MG包括主机：MH-110,MH-13

contact包含：WSP,HW,ZY

contactgroup包含：testers,virtualers,maintainers；testers包含用户：WSP，virtualers包含用户：WSP和HW,maintainers包含用户：ZY

为了直观起见，请看下图，

好了，有了大致模块以后，现在我们正式开始配置nagios吧

(1) host的编辑与添加

为了灵活使用，我们直接进入/usr/local/nagios/etc/objects目录下面，

[root@localhost src]# cd /usr/local/nagios/etc/objects/

[root@localhost objects]# vi hosts.cfg

##########################################################################

### Define whole host for all the machines

# Define testgroup host for the testers machine

define host{

host_name TH-02

alias testhost02

max_check_attempts 5

contact_groups testers

address 60.191.*.*

}

# Define virtualgroup host for the virtualers machine

define host{

host_name VH-178

alias Virutalhost178

max_check_attempts 5

contact_groups virtualers

address *.*.*.178

}

define host{

host_name VH-132

alias Virtualhost132

max_check_attempts 5

contact_groups virtualers

address *.*.*.132

}

# Define maintaingroup host for the maintainers machine

define host{

host_name MH-110

alias maintainhost110

max_check_attempts 5

contact_groups maintainers

address *.*.*.110

}

define host{

host_name MH-13

alias maintainhost13

max_check_attempts 5

contact_groups maintainers

address *.*.*.13

}

##############################################################################

### Define all hostgroup for the whole machine

# Define testgroup

define hostgroup{

hostgroup_name TG

alias testgroup

members TH-02

}

# Define virtualgroup

define hostgroup{

hostgroup_name VG

alias virtualgroup

members VH-178,VH-132

}

# Define maintaingroup

define hostgroup{

hostgroup_name MG

alias maintaingroup

members MH-110,MH-13

}

#############################################################################

### SERVICE DEFINITIONS

# Define a service to "ping" the whole machine

define service{

host_name TH-02,VH-178,VH-132,MH-110

service_description PING

is_volatile 0

check_period 24x7

max_check_attempts 1

normal_check_interval 1

retry_check_interval 1

notification_options w,u,c,r

notification_interval 1

notification_period 24x7

check_command check_ping!100.0,20%!500.0,60%

}

# Define a service to "HTTP" the whole machine

define service{

host_name H-02,VH-178,VH-132,MH-13,MH-110

service_description HTTP

is_volatile 0

check_period 24x7

max_check_attempts 1

normal_check_interval 1

retry_check_interval 1

notification_options w,u,c,r

notification_interval 1

notification_period 24x7

check_command check_http

notifications_enabled 0

}

service 可以根据自己的需要加的，我这里只对HTTP与PING来作阐述的。

(2) contacts.cfg的编辑

###############################################################################

# CONTACTS.CFG - SAMPLE CONTACT/CONTACTGROUP DEFINITIONS

# Last Modified: 05-31-2007

# NOTES: This config file provides you with some example contact and contact

# group definitions that you can reference in host and service

# definitions.

# You don't need to keep these definitions in a separate file from your

# other object definitions. This has been done just to make things

# easier to understand.

###############################################################################

# CONTACTS

###############################################################################

### Define contact information for all the contacter

# Define contact information for WSP

define contact{

contact_name WSP

use generic-contact

alias WY-wsp

service_notification_commands notify-service-by-email,service-notify-by-fei

host_notification_commands notify-host-by-email,host-notify-by-fei

email wsp@wy.cn

pager 150***

}

# Define contact information for HW

define contact{

contact_name HW

use generic-contact

alias WY-hw

service_notification_commands notify-service-by-email,service-notify-by-fei

host_notification_commands notify-host-by-email,host-notify-by-fei

email hewei@wy.cn

pager 135***

}

# Define contact information for ZY

define contact{

contact_name ZY

use generic-contact

alias WY-zy

service_notification_commands notify-service-by-email,service-notify-by-fei

host_notification_commands notify-host-by-email,host-notify-by-fei

email zy@wy.cn

pager 150***

}

###############################################################################

# CONTACT GROUPS

###############################################################################

### Define contact group for all ther whole contacter

# Define testers contact group

define contactgroup{

contactgroup_name testers

alias testhost contacters

members WSP

}

# Define virtualers contact group

define contactgroup{

contactgroup_name virtualers

alias virtualhost contacters

members WSP,HW

}

# Define maintainers contact group

define contactgroup{

contactgroup_name maintainers

alias maintainhost contacters

members ZY

}

(3) commands.cfg的编辑

为了支持飞信发短信的功能需要在此文件中添加飞信命令，以促使信息的发送，代码如下：

# 'notify-host-by-fei' command definition

define command {

command_name host-notify-by-fei ;

command_line /usr/local/fetion/fetion --mobile=137*** --pwd=*** --to=$CONTACTPAGER$ --msg-utf8="Host $HOSTSTATE$ alert for $HOSTNAME$! on '$LONGDATETIME$'" $CONTACTPAGER$

}

# 'notify-service-by-fei' command definition

define command {

command_name service-notify-by-fei

command_line /usr/local/fetion/fetion --mobile=137*** --pwd=*** --to=$CONTACTPAGER$ --msg-utf8="$HOSTADDRESS$ $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ on $LONGDATETIME$" $CONTACTPAGER$

}

(4) 编辑nagios.cfg

为了不监控本机，现把localhost注释掉，找到此行，并且加以注释：

# cfg_file=/usr/local/nagios/etc/objects/localhost.cfg

为了使刚才编辑的文件生效，需加入一行：

cfg_file=/usr/local/nagios/etc/objects/hosts.cfg

(5) 编辑cgi.cfg

为了保证权限能正常访问nagios的web页面，需把这些行的值改掉：

authorized_for_system_information=*

authorized_for_configuration_information=*

authorized_for_system_commands=nagios

authorized_for_all_services=*

authorized_for_all_hosts=*

authorized_for_all_service_commands=*

authorized_for_all_host_commands=*

*号在此表示所有用户，也可以改成相关用户，不过必须逐一添加。

服务器端的配置基本上大致如此了。

4、启动nagios与apache服务

(1) nagios自启动

[root@localhost objects]# service nagios restart

Running configuration check...done.

Stopping nagios: done.

Starting nagios: done.

[root@localhost objects]# chkconfig nagios on

[root@localhost objects]# chkconfig --list|grep nagios

nagios 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭

(2) apache的启动

[root@localhost ~]# export PATH=$PATH:/usr/local/apache/bin

[root@localhost ~]# apachectl -k start

httpd (pid 3108) already running

注：为了让apache可以自启动，可以加入到/etc/rc.local之中。

5、测试与浏览

在启动nagios服务之前，我们可以先测试一下是否配置有没有错误，或者你启动的时候出现错误也可以用下述命令进行测试

[root@localhost ~]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

呵呵，没有错误，可能您在配置之前或多或少会出现问题的，根据相关错误提示，逐一排查，相信您定会成功的。

现在我们打开nagios的web页面，输入： http://***.com/nagios样例

先看map页面，大致页面如下

再看hosts相关链接页面：

最后，我们再看一下hostgroups页面：

二、客户端的配置：

1、需求软件的下载：

nagios插件程序：

http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.13.tar.gz

nrpe软件：

http://prdownloads.sourceforge.net/sourceforge/nagios/nrpe-2.12.tar.gz

2、软件的安装

(1) nagios插件的安装：

首先在安装前建立nagios用户，命令如下：

[root@yibaner src]# useradd nagios -s /sbin/nologin -M

[root@yibaner src]# tar zxvf nagios-plugins-1.4.13.tar.gz

[root@yibaner src]# cd nagios-plugins-1.4.13

[root@yibaner nagios-plugins-1.4.13]# ./configure --prefix=/usr/local/nagios

[root@yibaner nagios-plugins-1.4.13]# make && make install

[root@yibaner nagios-plugins-1.4.13]# chown -R nagios.nagios /usr/local/nagios/

(2) nrpe的程序的安装：

[root@yibaner src]# tar zxvf nrpe-2.12.tar.gz

[root@yibaner nrpe-2.12]# cd nrpe-2.12

[root@yibaner nrpe-2.12]# ./configure

[root@yibaner nrpe-2.12]# make all

[root@yibaner nrpe-2.12]# make install-plugin

[root@yibaner nrpe-2.12]# make install-daemon

[root@yibaner nrpe-2.12]# make install-daemon-config

(3) 修改nrpe.cfg配置文件：

[root@yibaner nrpe-2.12]# vi /usr/local/nagios/etc/nrpe.cfg

将server_address的值修改为本机的IP地址：

server_address=*.*.*.110

将allowed_hosts的值修改为远程监控服务器的IP地址：

allowed_hosts=*.*.*.27

(4) 运行nrpe服务：

[root@yibaner nrpe-2.12]# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

(5) 查看nrpe运行情况：

[root@yibaner nrpe-2.12]# netstat -nap | grep nrpe
tcp 0 0 *.*.*.110:5666 0.0.0.0:* LISTEN 3538/nrpe

从上述情况来看，nrpe成功运行，并且占用了5666端口

(6) 设置nrpe自启动：

[root@yibaner nrpe-2.12]#vi /etc/rc.local

在其中加中此行：

/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

(7) 在监控服务器端测试被监控服务器是否正常运行

[root@localhost src]# telnet *.*.*.110 5666

测试如果一切正常，整个配置过程全部告一段落，只需到监控服务器中设置对被监控服务器的所需服务的监控即可。

这样一来，整个nagios的配置全部告一段落了，把被监控服务器的某个服务暂时停用一下，马上就会收到飞信的短消息了，一切表明，配置成功了。
