nagios3.5.1 server端源码编译安装方式

nagios目录结构如下：

主程序在/apps/svr/nagios目录；

配置文件/apps/conf/nagios

Nagios

1、解压

tar -xvzf nagios-3.5.1.tar.gz

2、编译

./configure -with-nagios-user=apps –with-nagios-group=apps –with-command-user=apps –with-command-group=apps –prefix=/apps/svr/nagios

make all

make install

make install-init (如果不需要service的方式运行，则不需要安装)

make install-config

make install-commandmode

make install-webconf（需要安装httpd之后才能运行它）

plugin

1、解压

tar -xvzf nagios-plugins-2.0.3.tar.gz

2、编译

./configure –with-nagios-use=apps –with-nagios-group=apps –prefix=/apps/svr/nagios

make

make install

NRPE（需要安装openssl-devel）

1、解压

tar -xvzf nrpe-2.15.tar.gz

2、

./configure –with-nrpe-user=apps –with-nrpe-group=apps –with-nagios-user=apps –with-nagios-group=apps –prefix=/apps/svr/nagios

make all

make install-plugin

make install-daemon

make install-daemon-config

3、修改nrpe.cfg

allowed_host 里面配置上server的地址。

插件安装

1、拷贝文件到libexec目录下

2、vi /apps/svr/nagios/etc/nrpe.cfg，添加如下两行

command[mycheck_disk_health]=/apps/svr/nagios/libexec/mycheck_disk_health.sh

command[mycheck_gmond]=/apps/svr/nagios/libexec/mycheck_gmond.sh

3（仅服务端需要）

vi /apps/svr/nagios/etc/objects/commands.cfg，添加：

define command{

command_name check_nrpe

command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$

}

配置监控主机

1、在objects下新建clients目录

2、在目录下添加以主机ip为名字的配置文件

vi 172.16.203.3.cfg

define host{

use linux-server

host_name 172.16.203.3

alias 172.16.203.3

address 172.16.203.3

#notifications_enabled 1

hostgroups 1

}

3、在nagios.cfg中增加如下一行：

cfg_dir=/apps/svr/nagios/etc/objects/clients

配置监控项

1、在objects目录下，增加services.cfg

define hostgroup{

hostgroup_name 1

alias 1

}

define service{

use local-service

hostgroup_name 1

service_description diskhealth

check_command check_nrpe!mycheck_disk_health （需要安装smartmontools）

}

define service{

use local-service

hostgroup_name 1

service_description gmond

check_command check_nrpe!mycheck_gmond

}

define service{

use local-service

hostgroup_name 1

service_description PING

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

}

2、在nagios.cfg中增加一行

cfg_file=/apps/svr/nagios/etc/objects/services.cfg

连接cmagent

1、拷贝 submit_check_result.sh 文件到/apps/svr/nagios/libexec，并附执行权限。

2、vi submit_check_result.sh 修改其中的url

3、vi nagios.cfg 修改如下字段：

enable_notifications=0

obsess_over_services=1

ocsp_command=submit_check_result

4、vi /usr/local/nagios/etc/objects/commands.cfg添加命令submit_check_result

define command{

command_name submit_check_result

command_line /apps/svr/nagios/libexec/submit_check_result.sh ‘$HOSTADDRESS$’ ‘$SERVICEDESC$’ ‘$SERVICESTATE$’ ‘$SERVICEOUTPUT$’ ‘$HOSTGROUPNAME$’

}

页面访问：

1、yum -y install httpd php

htpasswd -c /apps/svr/nagios/etc/htpasswd.users nagiosadmin

2、make install-webconf（需要安装httpd之后才能运行它）

3、修改httpd.conf，将user和group配置成apps

运行nrpe

bin/nrpe -c etc/nrpe.cfg -d

检查是否正常运行

libexec/check_nrpe -H 172.16.203.3

报错：CHECK_NRPE: Error - Could not complete SSL handshake

nrpe.cfg中allowed_host未配置。

运行nagios

/apps/svr/nagios/bin/nagios -d /apps/svr/nagios/etc/nagios.cfg

1、Check result queue contained results for host’locahost’, but the host could not be found! Perhaps you forgot to define the host in yourconfig files?

启动了两个nagios，关掉一个即可

2、NRPE: Unable to read output

直接用运行nagios的用户执行那个脚本，发现报错，所以是那个脚本的问题。大多数情况下会是权限的问题

检查配置文件：

/apps/svr/nagios/bin/nagios -v /apps/svr/nagios/etc/nagios.cfg

定制化修改：

1、log

vi nagios.cfg

log_file=/apps/logs/nagios/nagios.log

2、pid

vi nagios.cfg

lock_file=/apps/run/nagios/nagios.lock

3、conf

ln -s /apps/svr/nagios/etc/* /apps/conf/nagios/

报错：

make all

make[1]: * No rule to make target

../include/locations.h', needed by

broker.o’. Stop.

yum -y install perl

页面访问报错：

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

解决办法：

查看httpd的error日志，如果显示：

[authn_file:error] [pid 16158] (13)Permission denied: [client 172.16.207.38:64904] AH01620: Could not open password file: /apps/svr/nagios/etc/htpasswd.users

修改/apps/svr/nagios/etc/htpasswd.users权限

更改为777权限后，还是无法访问。切换到nagios用户，是可以访问这个文件的。很困惑。最后发现是selinux没有关闭。。

nagios页面，输入用户名密码之后看不到，因为默认启动httpd的是apache用户，而这个用户是没有权限访问nagios的

解决办法，修改httpd.conf

将user 和Gropu更改为对应的值
