本文在介紹關于nconf的安裝和配置的基礎上，重點探討了其具體步驟，步驟簡單易上手操作，文章內(nèi)容步步緊湊，希望大家根據(jù)這篇文章可以有所收獲。

nconf提供WEB界面，管理nagios配置，其將nagios配置文件放入數(shù)據(jù)庫，用戶做相應修改后點擊生成配置文件，Nconf會從數(shù)據(jù)庫中將配置寫入配置文件。所以最后nagios的配置還是以文件的形式存在，這是相對與nagioSQL本人比較喜歡Nconf的原因，其次Nconf還提供了靜態(tài)文件的修改頁面。

一、初始化數(shù)據(jù)庫
MySQL> create database nconf default character set utf8;
mysql> grant all privileges on nconf.* to 'nconf'@'localhost' identified by 'XXXX' with grant option;
mysql> grant all privileges on nconf.* to 'nconf'@'%' identified by 'XXXX' with grant option;
mysql> flush privileges;

二、安裝Nconf
#tar -zxvf  nconf-1.3.0-0.tgz -C /var/www/html/
#chown -R apache:apache /var/www/html/nconf

三、初始化Nconf

第二步驟需要建立軟連接，并且注意原文件的權限最好修改為777
#chmod 777 /usr/local/nagios/bin/nagios
#ln -s /usr/local/nagios/bin/nagios /var/www/html/nconf/bin/

#第四步結束后刪除臨時文件
#rm -rf /var/www/html/nconf/{INSTALL,INSTALL.php,UPDATE,UPDATE.php}

三、配置Nconf sudo權限和自動生成配置文件

#visudo

apache    ALL=(ALL)       NOPASSWD:/etc/init.d/nagios

//修改nconf配置文件
#cat /var/www/html/nconf/config/deployment.ini
[extract config]
type        = local
source_file = "/var/www/html/nconf/output/NagiosConfig.tgz"
target_file = "/var/www/html/nconf/temp/"
action      = extract

[copy collector config]
type        = local
source_file = "/var/www/html/nconf/temp/Default_collector/"
target_file = "/usr/local/nagios/etc/Default_collector/"
action      = copy

[copy global config]
type        = local
source_file = "/var/www/html/nconf/temp/global/"
target_file = "/usr/local/nagios/etc/global/"
action      = copy
reload_command = "sudo /etc/rc.d/init.d/nagios reload"

四、nconf生成配置文件的流程

點擊 Generate Nagios config后會檢測Nagios配置文件是否有問題

無問題后點擊 Deploy,就會安裝下面的流程和上面配置文件中配置的路徑去執(zhí)行相關操作。

（1）在 [extract config]配置的source_file下生成壓縮文件同時備份之前的壓縮文件，之后解壓到target_file下面

（2）按照[copy collector config]和 [copy global config]的配置，將source_file的文件復制到target_file下。

（3）執(zhí)行 sudo /etc/init.d/nagios reload

五、將現(xiàn)有配置導入Nconf中

（1）注意事項
按以下方式導入可避免配置文件之間的沖突：
1. timeperiods
2. misccommands & check_commands
3. contacts
4. contactgroups (considering that some contactgroups might be linked to others)
5. host-templates
6. parent-hosts, then remaining hosts
7. hostgroups (considering that some hostgroups might be linked to others)
8. host-dependencies（主機依賴）
9. service-templates
10. services
11. advanced-services
12. servicegroups (considering that some servicegroups might be linked to others)
13. service-dependencies

現(xiàn)有配置文件按屬性做更精細的分離，確保每個配置文件里面只有對應的配置屬性

（2）語法
Usage:
/var/www/html/nconf/bin/add_items_from_nagios.pl -c class -f /path/to/file [-x (1-5)] [-s]

Help:

 required

 -c  Specify the class of items that you wish to import. Must correspond to an NConf class
     (e.g. "host", "service, "hostgroup", "checkcommand", "contact", "timeperiod"...)

 -f  The path to the file which is to be imported. CAUTION: Make sure you have
     only items of one class in the same file (e.g. "hosts.cfg", "services.cfg"...)
     Also make sure you import host- or service-templates separately ("host" or
     "service" items containing a "name" attribute)

 optional

 -x  Set a custom loglevel (1 = lowest, 5 = most verbose)

 -s  Simulate only. Do not make any actual modifications to the database.
 
 #-s為測試模式，不會往數(shù)據(jù)庫插入任何數(shù)據(jù)
 /var/www/html/nconf/bin/add_items_from_nagios.pl -c timeperiod -f /usr/local/nagios/etc/objects/timeperiods.cfg -s
 
 （3）實戰(zhàn)
/var/www/html/nconf/bin/add_items_from_nagios.pl -c timeperiod -f /usr/local/nagios/etc/objects/timeperiods.cfg -s
/var/www/html/nconf/bin/add_items_from_nagios.pl -c misccommand  -f /usr/local/nagios/etc/objects/misccommands.cfg -s
/var/www/html/nconf/bin/add_items_from_nagios.pl -c checkcommand -f /usr/local/nagios/etc/objects/checkcommands.cfg -s
/var/www/html/nconf/bin/add_items_from_nagios.pl -c contact -f /usr/local/nagios/etc/objects/contacts.cfg -s
/var/www/html/nconf/bin/add_items_from_nagios.pl -c contactgroup -f /usr/local/nagios/etc/objects/contactgroup.cfg -s
/var/www/html/nconf/bin/add_items_from_nagios.pl -c host-template -f /usr/local/nagios/etc/objects/host-template.cfg -s
/var/www/html/nconf/bin/add_items_from_nagios.pl -c host -f /usr/local/nagios/etc/objects/hosts.cfg -s
/var/www/html/nconf/bin/add_items_from_nagios.pl -c service-template -f /usr/local/nagios/etc/objects/service-template.cfg -s
/var/www/html/nconf/bin/add_items_from_nagios.pl -c service -f /usr/local/nagios/etc/objects/services.cfg -s
/var/www/html/nconf/bin/add_items_from_nagios.pl -c service -f /usr/local/nagios/etc/objects/localhost.cfg -s

六、靜態(tài)文件修改功能

static_cfg默認路徑為/var/www/html/nconf/static_cfg

//創(chuàng)建一個測試文件

#echo "您好kjklsj111" >>/var/www/html/nconf/static_cfg/test.txt 

頁面點擊Administration->Edit static config files，你會發(fā)現(xiàn)有保存和下載按鈕，直接編輯文件后點擊保存就可
