Server 环境：CentOS-6.6 nagios-4.1.1 httpd-2.4.20 php-5.6.22

Server 安装：

useradd nagios 创建用户

mkdir /usr/local/nagios
chown -R nagios:nagios /usr/local/nagios?

tar -xzvf nagios-4.1.1.tar.gz.gz
cd nagios-4.1.1
ll
./configure –prefix=/usr/local/nagios
make all
yum install unzip
make all
make install
make install-init

./configure –prefix=/usr/local/php –with-apxs2=/usr/local/apache2/bin/apxs
make
make test
make install<br> cp php.ini-development /usr/local/lib/php.ini #php 配置

配置 apache，文件位置：usr/local/apache2/conf/http.conf

将进程启动用户改为 nagios，即：

User nagios

Group nagios

LoadModule php5_module modules/libphp5.so # 去掉此行前面注释

找到 DirectoryIndex 增加 index.php

并新增 SetHandler application/x-httpd-php 使其支持解析 php

在最后新增 nagios 配置：

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 None
AllowOverride None
Order allow,deny
Allow from all
AuthName “nagios Access”
AuthUserFile /usr/local/nagios/etc/htpasswd
Require valid-user
</Directory>

因为指定了访问验证文件，所以需要创建一个：

/usr/local/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd【登录用户名自己设置】回车后输入设置的密码即可

设置完成可以启动 nagios 和 apache 了

出现的问题：

本地可访问，局域网内其他主机不可访问，报 no router，此时是防火墙挡住了，可以关掉 server 防火墙：service iptables stop 或者新增一条放开监听端口 80（http.conf）的规则：iptables -I INPUT -p tcp –dport 80 -j ACCEPT

到此 server 安装完成，当然为了监控其他主机还需要配置相应的 nagios 文件。
