Nagios安装文档之Apache
Nagios安装文档
(Apache+Php+Nagios)
需求：监控多台服务器，及时报警
建议：nagios尽量单独安装到一台服务器上，避免与其他服务混合使用服务器
系统整体化境LANP(Debian6.0.5+Apache+Nagios+Php5.4)

参考文档：https://www.sodocs.net/doc/7017714008.html,/install-and-setup-debian.html
2.优化debian系统
参考文档：https://www.sodocs.net/doc/7017714008.html,
二、安装Apache服务器
1.下载apache
下载地址：https://www.sodocs.net/doc/7017714008.html,/download.cgi
2.编译安装
编译安装参数：
./configure --prefix=/usr/local/apache --enable-so--enable-cgi--enable-info--enable-rewrite--enable-speling--enable-usertrack--enabl e-deflate
--enable-ssl--enable-mime-magic--enable-module=so--enable-module=rewrite--enable-share d=max
3.启动apache
#/usr/local/apache/bin/apachectl start
#/usr/local/apache/bin/apachectl stop
#/usr/local/apache/bin/apachectl restart
三、安装PHP
1.安装php5.4
参考文档：https://www.sodocs.net/doc/7017714008.html,/debian-php5-4.html
注意：和nginx编译参数不同，改为：
./configure --prefix=/usr/local/php --enable-fpm --with-curl --with-gd --enable-mbstring --with-mysql --with-mysqli --enable-gd-native-ttf --enable-sockets --with-jpeg-dir --with-png-dir --with-freetype-dir --with-zlib --enable-ftp --with-apxs2=/usr/local/apache/bin/apxs
2.优化php
参考文档：https://www.sodocs.net/doc/7017714008.html,
四、配置apahce & php
1.配置apache的httpd.conf文件
A、修改文件/usr/local/apache/conf/httpd.conf添加默认文件
DirectoryIndex index.html index.htm index.php
B、加载支持php的模块
LoadModule php5_module modules/libphp5.so
C、添加php识别
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
D、测试php
此时创建i.php文件，如何http://ip/i.php可以访问则说明php环境配置ok 2.优化Apache
参考文档：https://www.sodocs.net/doc/7017714008.html,
3.重启Apache
#/usr/local/apache/bin/apachectl restart
五、安装Nagios
1.安装libgd2
root@lanp:~# aptitude search libgd2
root@lanp:~# aptitude install libgd2-xpm
2.创建nagios用户信息
root@dnnp:~# useradd -s /sbin/nologin nagios
root@dnnp:~# mkdir /usr/local/nagios
root@dnnp:~# chown nagios.nagios /usr/local/nagios
3.下载nagios
下载nagios相关软件：nagios-3.4.1.tar.gz、nagios-plugins-1.4.16.tar.gz
nagios下载地址：
https://www.sodocs.net/doc/7017714008.html,/project/nagios/nagios-3.x/nagios-3.4.1/nagios-3.4.1.tar.gz
nagios-plugins下载地址
https://www.sodocs.net/doc/7017714008.html,/project/nagiosplug/nagiosplug/1.4.16/nagi os-plugins-1.4.16.tar.gz
4.解压安装nagios
root@lanp:~/software#tar -zxvf nagios-3.4.1.tar.gz
root@lanp:~/software# cd nagios/
root@lanp:~/software/nagios# ./configure --prefix=/usr/local/nagios
root@lanp:~/software/nagios# make all
root@lanp:~/software/nagios# make install
root@lanp:~/software/nagios# make install-init
root@lanp:~/software/nagios# make install-commandmode
root@lanp:~/software/nagios# make install-config
5.修改配置文件contacts.cfg
修改配置文件/usr/local/nagios/etc/objects/contacts.cfg，将define contact里面的email改成自己的email
6.安装nagios插件
Nagios编译参数为：
./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios
root@lanp:~/software# tar -zxvf nagios-plugins-1.4.16.tar.gz
root@lanp:~/software# cd nagios-plugins-1.4.16/
root@lanp:~/software/nagios-plugins-1.4.16# ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios
root@lanp:~/software/nagios-plugins-1.4.16# make
root@lanp:~/software/nagios-plugins-1.4.16# make install
7.添加至系统服务
把Nagios加入到服务列表中以使之在系统启动时自动启动
root@lanp:~# ln -s /etc/init.d/nagios /etc/rcS.d/S99nagios
8.启动nagios
A、验证nagios配置文件
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
B、启动、关闭nagios
root@lanp:~# /etc/init.d/nagios start/stop/restart
root@lanp:~# service nagios start/stop/restart
六、配置Apache和Nagios结合点
1.创建验证文件
文件为/usr/local/nagios/etc/https://www.sodocs.net/doc/7017714008.html,er 用户名为nagiosadmin
root@lanp:~#/usr/local/apache/bin/htpasswd -c /usr/local/nagios/etc/https://www.sodocs.net/doc/7017714008.html,er nagiosadmin
2.添加nagios配置文件
添加nagios配置文件，文件路径：/usr/local/apache/conf/conf.d/nagios.conf配置文件内容为：
# SAMPLE CONFIG SNIPPETS FOR APACHE WEB SERVER
# Last Modified: 11-26-2005
#
# This file contains examples of entries that need
# to be incorporated into your Apache web server
# configuration file. Customize the paths, etc. as
# needed to fit your system.
ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
# SSLRequireSSL
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
# Order deny,allow
# Deny from all
# Allow from 127.0.0.1
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/https://www.sodocs.net/doc/7017714008.html,er
Require valid-user
Alias /nagios "/usr/local/nagios/share"
# SSLRequireSSL
Options None
AllowOverride None
Order allow,deny
Allow from all
# Order deny,allow
# Deny from all
# Allow from 127.0.0.1
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/https://www.sodocs.net/doc/7017714008.html,er
Require valid-user
3.修改apache配置文件
修改apache配置文件/usr/local/apache/conf/httpd.conf
A、在结尾添加Include /usr/local/apache/conf/conf.d/nagios.conf
B、LoadModule cgid_module modules/mod_cgid.so前面的注释去掉
C、AddHandler cgi-script .cgi .pl 前面注释去掉
4.重启apache
root@lanp:~# /usr/local/apache/bin/apachectl restart
完成验证
打开http://192.168.20.132/nagios/ 输入密码就可以看到nagios 的主页面
主要命令
Nagios文件验证：/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg Nagios重启：/etc/init.d/nagios start/stop/restart
Apache重启：/usr/local/apache/bin/apachectl restart
注：nagios必须开启的服务
Php
Apache
Nagios
