下载地址如下： http://sourceforge.net/projects/nagios/files/

具体详细下载地址：http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-4.0.6.tar.gz

1 开始下载：
 wget http://sourceforge.net/projects/nagios/files/nagios-4.x/nagios-4.0.6/nagios-4.0.6.tar.gz/download?use_mirror=jaist
如下图所示，下载free版本的。

安装前准备工作，安装一些lib包：

[root@cache-2 root]# yum -y install httpd gcc glibc glibc-common

# yum install -y gcc glibc glibc-common gd gd-devel xinetd openssl-devel


2 进行selinux设置，或者关闭selinux

 查看SELinux状态：

 (1)/usr/sbin/sestatus -v      ##如果SELinux status参数为enabled即为开启状态

         SELinux status:                 enabled

 (2)getenforce                 ##也可以用这个命令检查

 关闭SELinux：

 (3)临时关闭（不用重启机器）：

         setenforce 0                  ##设置SELinux 成为permissive模式

                              ##setenforce 1 设置SELinux 成为enforcing模式

 (4)修改配置文件需要重启机器：

         修改/etc/selinux/config 文件

         将SELINUX=enforcing改为SELINUX=disabled

         重启机器即可


3 开始准备nagios安装环境

  (1) 添加nagios运行所需要的用户和组：

  groupadd nagcmd

         useradd -m nagios

         usermod -a -G nagcmd nagios

        

把apache加入到nagcmd组，以便于在通过web Interface操作nagios时能够具有足够的权限：

# usermod -a -G nagcmd apache


4 编译安装准备

./configure --with-command-group=nagios --prefix=/opt/app/nagios --enable-embedded-perl --with-httpd-conf=/usr/local/apache2/conf

[root@cache-2 nagios-4.0.6]# ./configure --with-command-group=nagios  --prefix=/opt/app/nagios --enable-embedded-perl  --with-httpd-conf=/usr/local/apache2/conf
checking for a BSD-compatible install... /usr/bin/install -c
checking build system type... x86_64-unknown-linux-gnu

 HTML URL:  http://localhost/nagios/
                  CGI URL:  http://localhost/nagios/cgi-bin/

Review the options above for accuracy.  If they look okay,
type ‘make all‘ to compile the main program and CGIs.


5 开始make安装
5.1 make all
[root@cache-2 nagios-4.0.6]#  make all

cd ./base && make

5.3 make install-config
[root@cache-2 nagios-4.0.6]# make install-config
/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc
/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc/objects

*** Config files installed ***


5.4 make install-commandmode

[root@cache-2 nagios-4.0.6]# make install-commandmode
/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/var/rw
chmod g+s /usr/local/nagios/var/rw

*** External command directory configured ***

Remember, these are *SAMPLE* config files.  You‘ll need to read
the documentation for more information on how to actually define
services, hosts, etc. to fit your particular needs.


5.5 make install-init

[root@cache-2 nagios-4.0.6]# make install-init
/usr/bin/install -c -m 755 -d -o root -g root /etc/rc.d/init.d
/usr/bin/install -c -m 755 -o root -g root daemon-init /etc/rc.d/init.d/nagios

*** Init script installed ***


[root@cache-2 nagios-4.0.6]#

加到启动项里面去：

# chkconfig --add nagios

# chkconfig --level 35 nagios on

# chkconfig --list nagios

bubuko.com,布布扣

检查主机配置文件是否正确：

/var/www/nagios/bin/nagios -v /var/www/nagios/etc/nagios.cfg


5.6 Check安装是否正确：

5.6.1说明：

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。Nagios 各个目录用途说明如下：

bin    Nagios 可执行程序所在目录

etc   Nagios 配置文件所在目录

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

libexec      Nagios 外部插件所在目录

var   Nagios 日志文件、lock 等文件所在的目录

var/archives     Nagios 日志自动归档目录

var/rw      用来存放外部命令文件的目录


5.6.2 check
 cd /usr/local/nagios
ll

[root@cache-2 nagios-4.0.6]# cd /usr/local/nagios
[root@cache-2 nagios]# ll

[root@cache-2 ~]#./configure --with-nagios-user=nagios --with-nagios-group=nagios  --prefix=/usr/local/nagios --with-mysql
[root@cache-2 ~]# make && make install



5.8 安装配置apache和php
(1)安装apache
下载 wget http://archive.apache.org/dist/httpd/httpd-2.4.7.tar.gz
[root@cache-2 ~]# wget http://archive.apache.org/dist/httpd/httpd-2.4.7.tar.gz

开始安装：
 tar -xvf httpd-2.4.7.tar.gz
 cd httpd-2.4.7
 ./configure --prefix=/usr/local/apache2
make && make install

[root@cache-2 ~]# tar -xvf httpd-2.4.7.tar.gz

Google之后，发现可能是gcc版本太低了，可能是apache版本太高，换低点的2.2.23版本吧。
wget http://archive.apache.org/dist/httpd/httpd-2.2.23.tar.gz
tar -xvf  httpd-2.2.23.tar.gz
cd httpd-2.2.23
./configure --prefix=/usr/local/apache2
make && make install

(2) 安装php版本

wget http://cn2.php.net/distributions/php-5.4.26.tar.gz

tar -xvf php-5.4.26.tar.gz

cd php-5.4.26

./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs

有报错信息：

configure: error: xml2-config not found. Please check your libxml2 installation.

 

需要重新安装lib包

yum install libxml2 –y

yum install libxml2-devel –y

 

之后继续make，成功了：

Make && make install

Installing PDO headers:          /usr/local/php/include/php/ext/pdo/


(3) 配置apache

Apache的配置文件在 /usr/local/apache2/conf/httpd.conf ，vim打开

将

User daemon

Group daemon

修改成：

User nagios

Group nagios


将

<IfModule dir_module>

　　DirectoryIndex index.html

</IfModule>

修改成：

<IfModule dir_module>

　　DirectoryIndex index.html index.php

    AddType application/x-httpd-php .php

</IfModule>

 

为了安全起见：nagios的web监控页面需要经过授权才能访问，这需要增加验证配置，即在httpd.conf 文件最后添加如下信息：

#setting for nagios

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

     AuthName "Nagios Access"

     AuthUserFile /usr/local/nagios/etc/htpasswd  //用于此目录访问身份验证的文件             

     Require valid-user

</Directory>

Alias /nagios "/usr/local/nagios/share"

<Directory "/usr/local/nagios/share">

     AuthType Basic

     Options None

     AllowOverride None

     Order allow,deny

     Allow from all

     AuthName "nagios Access"

     AuthUserFile /usr/local/nagios/etc/htpasswd

     Require valid-user

</Directory>


(4) 创建apache目录验证文件

在上面的配置中，指定了目录验证文件htpasswd，下面要创建这个文件：

/usr/local/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd david

[root@cache-2 php-5.4.26]#  /usr/local/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd david

New password:

Re-type new password:

Adding password for user david

查看认证文件的内容：

[root@cache-2 php-5.4.26]#  cat /usr/local/nagios/etc/htpasswd

david:$apr1$Pf9XIJjd$m5hR2vw70MlqwrChgN7zc/

[root@cache-2 php-5.4.26]#

 

启动apache服务：

/usr/local/apache2/bin/apachectl start


[root@cache-2 php-5.4.26]# /usr/local/apache2/bin/apachectl start

httpd: Could not reliably determine the server‘s fully qualified domain name, using 10.254.3.41 for ServerName

(98)Address already in use: make_sock: could not bind to address [::]:80

(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80

no listening sockets available, shutting down

Unable to open logs

修改ServerName以及Port

vi /usr/local/apache2/conf/httpd.conf

ServerName 改成 10.xx.3.x1

Listen 80 改成 Listen 81

http://10.xx.3.x1:81/nagios/，可以打开了，如下所示：
