*** Configuration summary for nagios 3.5.0rc2 03-09-2013 ***: General Options: ------------------------- Nagios executable: nagios Nagios user/group: nagios,nagios Command user/group: nagios,nagios Embedded Perl: no Event Broker: yes Install ${prefix}: /usr/local/nagios #PID号 Lock file: ${prefix}/var/nagios.lock #检查结果目录 Check result directory: ${prefix}/var/spool/checkresults #服务配置目录 Init directory: /etc/rc.d/init.d #apache for nagios目录 Apache conf.d directory: /etc/httpd/conf.d #mail程序 Mail program: /bin/mail #主机名 Host OS: linux-gnu Web Interface Options: ------------------------ HTML URL: http://localhost/nagios/ CGI URL: http://localhost/nagios/cgi-bin/ Traceroute (used by WAP): Review the options above for accuracy. If they look okay, type 'make all' to compile the main program and CGIs. |
| *** Compile finished ***
If the main program and CGIs compiled without any errors, you can continue with installing Nagios as follows (type 'make' without any arguments for a list of all possible options): make install - This installs the main program, CGIs, and HTML files #安装主程序，CGI文件和Html文件。 make install-init - This installs the init script in /etc/rc.d/init.d #安装nagios服务，脚本在/etc/rc.d/init.d/nagios make install-commandmode - This installs and configures permissions on the directory for holding the external command file #安装和配置权限在外部命令目录 make install-config - This installs *SAMPLE* config files in /usr/local/nagios/etc You'll have to modify these sample files before you can use Nagios. Read the HTML documentation for more info on doing this. Pay particular attention to the docs on object configuration files, as they determine what/how things get monitored! #把样版配置文件拷到/usr/local/nagios/etc目录。 make install-webconf - This installs the Apache config file for the Nagios web interface #安装apache配置nagios选项文件。yum安装会创建/etc/http/conf.d/nagios.cfg make install-exfoliation - This installs the Exfoliation theme for the Nagios web interface #主题 make install-classicui - This installs the classic theme for the Nagios web interface #经典主题 |

| # OBJECT CACHE FILE
# This option determines where object definitions are cached when # Nagios starts/restarts. The CGIs read object definitions from # this cache file (rather than looking at the object config files # directly) in order to prevent inconsistencies that can occur # when the config files are modified after Nagios starts. 对象缓存文件。这些选项将决定当Nagios启动时或重新启动时，对象定义将被缓存在什么地方。CGI将从这个对象文件中读取对象的定义，而不是在之前的对象配置文件路径中去找。这样做是为了避免修改Nagios配置文件后引起的不一致问题。换句简单的话说就是更改配置文件后要重新运新Nagios新的配置参数才会生效，而当前运行的Nagios只参考缓存中的配置参数而已。 object_cache_file=/var/log/nagios/objects.cache |
| # EXTERNAL COMMAND FILE
# This is the file that Nagios checks for external command requests. # It is also where the command CGI will write commands that are submitted # by users, so it must be writeable by the user that the web server # is running as (usually 'nobody'). Permissions should be set at the # directory level instead of on the file, as the file is deleted every # time its contents are processed. 这是Nagios用来检查外部命令请求的文件。这个文件同样也是用户操作提交与CGI命令写入的地方，所以这个文件必须对于相关服务可写，一般是针对Apache的宿主用户可写。并且注意，这个文件所在的目录的权限必须被Apache可写，而不单指这文件，因为这个文件在工作当中是频繁被删除的。（之前我们将Apahe归入Nagios组的时候就已经完成了） command_file=/var/log/nagios/rw/nagios.cmd |
| # STATUS FILE
# This is where the current status of all monitored services and # hosts is stored. Its contents are read and processed by the CGIs. # The contents of the status file are deleted every time Nagios # restarts. 状态文件。这个文件将保存着目前检测到的服务和主机数据信息。这个文件当中的内容是被CGI读取并处理的，而它也是在每次Nagios重新启动的时候被删除清空的。 status_file=/var/log/nagios/status.dat |
