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。
