好了，有图了

Nagios安装

准备帐号，目录

[root@localhost cacti]# cd /soft/

[root@localhost soft]# useradd nagios

[root@localhost soft]# mkdir /usr/local/nagios

[root@localhost soft]# chown -R nagios.nagios /usr/local/nagios/

开始安装

[root@localhost soft]# tar zxvf nagios-3.2.0.tar.gz

[root@localhost soft]# cd nagios-3.2.0

[root@localhost nagios-3.2.0]# ./configure --prefix=/usr/local/nagios ;make all;make install;make install-init;make install-commandmode;make install-config;make install-webconf

修改nagios页面

[root@localhost nagios-3.2.0]# cp /etc/httpd/conf.d/nagios.conf /var/www/html/

生成 nagios页面访问账号

[root@localhost nagios-3.2.0]# touch /usr/local/nagios/etc/htpasswd.users

[root@localhost nagios-3.2.0]# htpasswd -c /usr/local/nagios/etc/htpasswd.users admin

帐号：admin                  密码：123

Nagios的 CGI配置文件

[root@localhost nagios-3.2.0]# vi /usr/local/nagios/etc/cgi.cfg（如下图）

[root@localhost nagios-3.2.0]# grep -v ^# /usr/local/nagios/etc/cgi.cfg |grep -v ^$

测试 nagios是否成功

[root@localhost nagios-3.2.0]# service nagios start

Starting nagios: done.

[root@localhost nagios-3.2.0]# chkconfig nagios on

[root@localhost nagios-3.2.0]# service httpd restart

汉化（选做）

[root@localhost nagios-3.2.0]# cd /soft/

[root@localhost soft]# tar jxvf nagios-cn-3.2.0.tar.bz2

[root@localhost soft]# cd nagios-cn-3.2.0

[root@localhost nagios-cn-3.2.0]# ./configure;make all;make install

[root@localhost nagios-cn-3.2.0]# service httpd restart

nagios-plugins插件安装

[root@localhost nagios-cn-3.2.0]# cd /soft/

[root@localhost soft]# tar zxvf nagios-plugins-1.4.14.tar.gz

[root@localhost soft]# cd nagios-plugins-1.4.14

[root@localhost nagios-plugins-1.4.14]# ./configure --prefix=/usr/local/nagios ;make ;make install

插件装好，监控的localhost正常了

PHP支持 JSON扩展

[root@localhost nagios-plugins-1.4.14]# cd /soft/

[root@localhost soft]# tar jxvf php-json-ext-1.2.1.tar.bz2

[root@localhost soft]# cd php-json-ext-1.2.1

[root@localhost php-json-ext-1.2.1]# vi /var/www/html/test.php

[root@localhost php-json-ext-1.2.1]# service httpd restart

[root@localhost php-json-ext-1.2.1]# service httpd restart

查看网页，出来json成功

ndoutils安装

[root@localhost php-json-ext-1.2.1]# cd /soft/

[root@localhost soft]# tar zxvf ndoutils-1.4b9.tar.gz

[root@localhost ndoutils-1.4b9]#./configure --with-mysql-inc=/usr/include/mysql --with-mysql-lib=/usr/lib/mysql --enable-mysql --with-ndo2db-user=nagios --with-ndo2db-group=nagios

[root@localhost ndoutils-1.4b9]# make (不make install)

[root@localhost ndoutils-1.4b9]# cd src/

[root@localhost src]# cp ndomod-3x.o ndo2db-3x log2ndo file2sock /usr/bin

[root@localhost src]# cd ../config

[root@localhost config]# cp ndo2db.cfg-sample ndo2db.cfg

[root@localhost config]# cp ndomod.cfg-sample ndomod.cfg

[root@localhost config]# cp ndo2db.cfg ndomod.cfg /usr/local/nagios/etc/

[root@localhost config]# cd /usr/local/nagios/etc/

[root@localhost etc]# vi ndo2db.cfg

[root@localhost etc]# vi /usr/local/nagios/etc/nagios.cfg

NPC安装

[root@localhost etc]# cd /soft/

[root@localhost soft]# tar zxvf npc-2.0.4.tar.gz

[root@localhost soft]# mv npc/ /var/www/html/cacti/plugins/

[root@localhost soft]# vi /var/www/html/cacti/include/global.php

NPC界面设置

登陆cacti

找到UserManagement

进去把勾plugin Management勾上，保存

点 settings下面的plugin management，在点INSTALL，然后enable

装好了

返回（console）菜单栏，点击 configuration-------settings----NPC，修改一下三个参数（如下图，cmd填写上就行，命令会自动生成）

点击NPC为OFF

启动ndo2db

[root@localhost soft]# ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg

[root@localhost soft]# service nagios restart

[root@localhost soft]# cat /var/log/messages

第一行报错：是因为没给ndo2db文件权限

[root@localhost soft]#chown nagios.nagios /usr/local/nagios/etc/ndo*

[root@localhost soft]# service nagios restart

[root@localhost soft]# cat /var/log/messages

Jul  5 17:37:46 localhost ndo2db-3x: mysql_error: 'Unknown column 'long_output' in 'field list''

这次是，数据库有问题

[root@localhost soft]# mysql -ucactiuser -ppwd123

mysql> use cacti;

alter table npc_eventhandlers add long_output TEXT NOT NULL default '' after output;

alter table npc_hostchecks add long_output TEXT NOT NULL default '' after output;

alter table npc_hoststatus add long_output TEXT NOT NULL default '' after output;

alter table npc_notifications add long_output TEXT NOT NULL default '' after output;

alter table npc_servicechecks add long_output TEXT NOT NULL default '' after output;

alter table npc_servicestatus add long_output TEXT NOT NULL default '' after output;

alter table npc_statehistory add long_output TEXT NOT NULL default '' after output;

alter table npc_systemcommands add long_output TEXT NOT NULL default '' after output;

执行这些语句，在重启nagios

[root@localhost soft]# service nagios restart

[root@localhost soft]# cat /var/log/messages

Ndo2db启动成功，现在就可以看到NPC的数据了。
