安装环境：centos5.5
Nginx平台安装
1、下载相关软件
2、建立相关用户
3、安装Nagios
4、安装Nagios插件
5、配置Nagios启动
6、安装Perl fcgi模块，让Nginx支持CGI
建立nginx-fcgi脚本
把下面内容写进脚本，并授执行权限

} } }
运行脚本：
把sock授权777：
7、配置登陆帐号及密码
注意：如果这里生成的用户不是nagiosadmin的话，需要在/usr/local/nagios/etc/cgi.cfg
配置文件里添加上你的帐号，否则你新建的lihp帐号会没有权限操作nagios
如果没有apache，可以在网上在线生成一个htpasswd
8、Nginx创建虚拟主机
以下是我的虚拟主机配置
server { listen80; ; root/usr/local/nagios/share; indexindex.php; auth_basic"lihp"; auth_basic_user_file/usr/local/nginx/conf/htpasswd; #access_log/usr/local/nginx/logs/nagios.lognagios; location~\.cgi${ root/usr/local/nagios/sbin; rewrite^/nagios/cgi-bin/(.*)\.cgi/$1.cgibreak; fastcgi_indexindex.cgi; fastcgi_passunix:/usr/local/nginx/logs/nginx-fcgi.sock; fastcgi_paramSCRIPT_FILENAME/usr/local/nagios/sbin$fastcgi_script_name; fastcgi_paramQUERY_STRING$query_string; fastcgi_paramREMOTE_ADDR$remote_addr; fastcgi_paramREMOTE_PORT$remote_port; fastcgi_paramREQUEST_METHOD$request_method; fastcgi_paramREQUEST_URI$request_uri; fastcgi_paramREMOTE_USER$remote_user; #fastcgi_paramSCRIPT_NAME$fastcgi_script_name; fastcgi_paramSERVER_ADDR$server_addr; fastcgi_paramSERVER_NAME$server_name; fastcgi_paramSERVER_PORT$server_port; fastcgi_paramSERVER_PROTOCOL$server_protocol; fastcgi_paramSERVER_SOFTWAREnginx; fastcgi_paramCONTENT_LENGTH$content_length; fastcgi_paramCONTENT_TYPE$content_type; fastcgi_paramGATEWAY_INTERFACECGI/1.1; fastcgi_paramHTTP_ACCEPT_ENCODINGgzip,deflate; fastcgi_paramHTTP_ACCEPT_LANGUAGEzh-cn; } location~.*\.(php|php5)?$ { #fastcgi_passunix:/tmp/php-cgi.sock; fastcgi_pass127.0.0.1:9000; fastcgi_indexindex.php; includefcgi.conf; } }
最后重读配置：
然后绑定HOSTS，打开浏览器
9、图片不正常的修正方法：
10、加载GD动态库(0608更新)
然后手动运行一下：
解决了map和trends错误的问题！
