Nginx平台安装Nagios监控服务(0608更新)

xuesn

　　安装环境：centos5.5
　　Nginx平台安装
　　1、下载相关软件
　　

　　FCGI-0.67.tar.gz
　　
FCGI-ProcManager-0.18.tar.gz
　　
IO-All-0.39.tar.gz
　　
nagios-3.2.3.tar.gz
　　
nagios-plugins-1.4.15.tar.gz
　　2、建立相关用户
　　

　　useradd nagios
　　
groupadd nagcmd
　　
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
　　
cd FCGI-ProcManager-0.18
　　
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 &quot;lihp&quot;;
  
• 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！
