安装环境:centos5.5
1、下载相关软件
FCGI-0.67.tar.gz |
2、建立相关用户
useradd nagios |
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 |
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 tar zxf IO-All-0.39.tar.gz |
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 reload |
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!
