nagios安装之前的准备，nagios在3.1.x之后需要需要php的支持，所以在这里就要安装php和http相关的支持。
一， 创建nagios用户和组
[root@test2 ~]# useradd -s /sbin/nologin nagios
[root@test2 ~]# mkdir /usr/local/nagios
[root@test2 ~]# chown -R nagios.nagios /usr/local/nagios/
二， http 和php 安装配置
（1）http安装
[root@test2 ~]# tar zxvf httpd-2.2.11.tar.gz
[root@test2 ~]# cd httpd-2.2.11
[root@test2 httpd-2.2.11]# ./configure --prefix=/usr/local/apache2 --enable-so
[root@test2 httpd-2.2.11]# make && make install
[root@test2 ~]# /usr/local/apache2/bin/apachectl start
（2）php安装
[root@test2 ~]# yum install -y libpng libpng-devel libjpeg libjpeg-devel freetype freetype-devel gd gd-devel mysql-devel libxml2-devel libxml2
[root@test2 ~]# mkdir /usr/local/php
[root@test2 ~]# cd php-5.2.9
[root@test2 php-5.2.9]# yum install -y libxml2-devel
[root@test2 php-5.2.9]# ./configure --prefix=/usr/local/php/ --with-apxs2=/usr/local/apache2/bin/apxs
[root@test2 php-5.2.9]# make && make install
（3）配置php和http
修改配置文件[root@test2 ~]# vim /usr/local/apache2/conf/httpd.conf
User nagios
Group nagios
AddType application/x-httpd-php .php
<IfModule dir_module>
DirectoryIndex index.php index.html
</IfModule>
三，安装nagios
（1）安装nagios
[root@test2 ~]# tar zxvf nagios-3.2.0.tar.gz
[root@test2 ~]# cd nagios-3.2.0
[root@test2 nagios-3.2.0]# ./configure --prefix=/usr/local/nagios/
[root@test2 nagios-3.2.0]# make all
[root@test2 nagios-3.2.0]# make install
[root@test2 nagios-3.2.0]# make install-init 产生开机脚本
/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@test2 nagios-3.2.0]# make install-commandmode 修改权限
/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 ***
[root@test2 nagios-3.2.0]# make install-config 产生配置文件
/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios//etc
（2）nagios插件的安装

[root@test2 ~]# tar zxvf nagios-plugins-1.4.9.tar.gz
[root@test2 ~]# cd nagios-plugins-1.4.9
[root@test2 nagios-plugins-1.4.9]# ./configure --prefix=/usr/local/nagios/
[root@test2 nagios-plugins-1.4.9]# make && make install
（3）中文化插件的安装
注意：这里的汉化软件要和nagios 的版本一致，否则会出现问题
[root@test2 ~]# tar jxvf nagios-cn-3.2.0.tar.bz2
[root@test2 ~]# cd nagios-cn-3.2.0
[root@test2 nagios-cn-3.2.0]# ./configure --prefix=/usr/local/nagios/
[root@test2 nagios-cn-3.2.0]# make all
[root@test2 nagios-cn-3.2.0]# make install && make install-init && make install-commandmode && make install-config && make install-webconf
（4）配置安全的http的nagios
[root@test2 ~]# cd /usr/local/apache2/conf/httpd.conf
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
Require valid-user
</Directory>
Alias /nagios "/usr/local/nagios/share"
<Directory "/usr/local/nagios/share">
AuthType Basic
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthUserFile /usr/local/nagios/etc/htpasswd
Require valid-user
</Directory>
[root@test2 ~]# /usr/local/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd chenzhongyang
New password:
Re-type new password:
Adding password for user chenzhongyang
四，排错
一、Starting nagios:This account is currently not available nagios启动报错
如果出现如下的提示修改nagios的shell
Starting nagios:This account is currently not available.
# service nagios restart
Running configuration check…done.
Stopping nagios: done.
Starting nagios:This account is currently not available.
done.
解决方法：
修改/etc/passwd
将/sbin/nologin改成/bin/bash
