usermod -g nagcmd nagios
usermod -g nagcmd www
3、安装Nagios
tar zxvf nagios-3.2.3.tar.gz
cd nagios-3.2.3
./configure --with-group=nagios --with-user=nagios --with-command-group=nagcmd --with-gd-lib=/usr/local/gd/lib --with-gd-inc=/usr/local/gd/include (0608更新)
make all
make install
make install-init
make install-config
make install-commandmode
4、安装Nagios插件
tar zxvf nagios-plugins-1.4.15.tar.gz
cd nagios-plugins-1.4.15
./configure --with-nagios-user=nagios --with-nagios-group=nagios
make
make install
5、配置Nagios启动
chkconfig --add nagios
chkconfig nagios on
service nagios start
6、安装Perl fcgi模块，让Nginx支持CGI
tar -zxf FCGI-0.67.tar.gz
cd FCGI-0.67
perl Makefile.PL
make && make install
tar -zxf FCGI-ProcManager-0.18.tar.gz

perl Makefile.PL
make && make install
tar zxf IO-All-0.39.tar.gz
cd IO-All-0.39
perl Makefile.PL
make && make install
建立nginx-fcgi脚本
vi /usr/local/nginx/sbin/nginx-fcgi 把下面内容写进脚本，并授执行权限

chmod +x /usr/local/nginx/sbin/nginx-fcgi 运行脚本：
/usr/local/nginx/sbin/nginx-fcgi -l /usr/local/nginx/logs/nginx-fcgi.log -pid /usr/local/nginx/logs/nginx-fcgi.pid -S /usr/local/nginx/logs/nginx-fcgi.sock
把sock授权777：
chmod 777/usr/local/nginx/logs/nginx-fcgi.sock 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
/usr/local/apache2/bin/htpasswd -c /usr/local/nginx/conf/htpasswd lihp 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
[*]{
[*]listen 80;
[*]server_name www.nagios.com;
[*]root /usr/local/nagios/share;
[*]index index.php;
[*]auth_basic "lihp";
[*]auth_basic_user_file /usr/local/nginx/conf/htpasswd;
[*]
[*]
[*]#access_log /usr/local/nginx/logs/nagios.log nagios;
[*]location ~ \.cgi$ {
[*]root /usr/local/nagios/sbin;
[*]rewrite ^/nagios/cgi-bin/(.*)\.cgi /$1.cgi break;
[*]fastcgi_index index.cgi;
[*]fastcgi_pass unix:/usr/local/nginx/logs/nginx-fcgi.sock;
[*]fastcgi_param SCRIPT_FILENAME /usr/local/nagios/sbin$fastcgi_script_name;
[*]fastcgi_param QUERY_STRING $query_string;
[*]fastcgi_param REMOTE_ADDR $remote_addr;
[*]fastcgi_param REMOTE_PORT $remote_port;
[*]fastcgi_param REQUEST_METHOD $request_method;
[*]fastcgi_param REQUEST_URI $request_uri;
[*]fastcgi_param REMOTE_USER $remote_user;
[*]#fastcgi_param SCRIPT_NAME $fastcgi_script_name;
[*]fastcgi_param SERVER_ADDR $server_addr;
[*]fastcgi_param SERVER_NAME $server_name;
[*]fastcgi_param SERVER_PORT $server_port;
[*]fastcgi_param SERVER_PROTOCOL $server_protocol;
[*]fastcgi_param SERVER_SOFTWARE nginx;
[*]fastcgi_param CONTENT_LENGTH $content_length;
[*]fastcgi_param CONTENT_TYPE $content_type;
[*]fastcgi_param GATEWAY_INTERFACE CGI/1.1;
[*]fastcgi_param HTTP_ACCEPT_ENCODING gzip,deflate;
[*]fastcgi_param HTTP_ACCEPT_LANGUAGE zh-cn;
[*]}
[*]location ~ .*\.(php|php5)?$
[*]{
[*]#fastcgi_pass unix:/tmp/php-cgi.sock;
[*]fastcgi_pass 127.0.0.1:9000;
[*]fastcgi_index index.php;
[*]include fcgi.conf;
[*]}
[*]}
最后重读配置：
/usr/local/nginx/sbin/nginx -s>然后绑定HOSTS，打开浏览器www.nagios.com 9、图片不正常的修正方法：
mkdir -p /usr/local/nagios/share/nagios
ln -s /usr/local/nagios/share/images /usr/local/nagios/share/nagios/images
ln -s /usr/local/nagios/share/stylesheets /usr/local/nagios/share/nagios/stylesheets
10、加载GD动态库(0608更新)
vi /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/local/gd/lib #加入GD动态库路径
然后手动运行一下：
ldconfig 解决了map和trends错误的问题！
