有可能有出现的问题
 

1.php make的时候报错
configure: error: xml2-config not found. Please check your libxml2 installation.
apt-get install libxml2
apt-get install libxml2-dev
2.httpd: Could not determine the server’s fully qualified domain name, using 127.0.1.1 for ServerName
修改httpd.conf文件，把其中到#ServerName的注释去掉即可。
vi /usr/local/apache2/conf/httpd.conf
3.You don’t have permission to access /nagios/ on this server
这是解析出错了，需要查看 tail -f /usr/local/apache2/logs/error_log 进行具体的分析，有可能是配置文件 ，也有可能是权限问题.
看到报错信息 attempt to invoke directory as script: /usr/local/nagios/share/
原来share目录不能配成ScriptAlias,而只能配成 Alias
