（如果報錯：configure: error: Please fix the library issues listed above and try again.

[root@localhost rrdtool-1.4.5]# yum -y install pango*后在安裝）

Cacti安裝

[root@localhost soft]# tar zxvf cacti-0.8.7e.tar.gz

[root@localhost soft]# mv cacti-0.8.7e /var/www/html/cacti

[root@localhost soft]# chown -R root.root /var/www/html/cacti/

添加個用來讀寫監(jiān)測數(shù)據(jù)的用戶賬號：runct，調整子目錄rra/,log/的屬主權限

[root@localhost soft]# chown -R runct.runct /var/www/html/cacti/rra /var/www/html/cacti/log

導入cacti.sql，建立數(shù)據(jù)庫、表結構

[root@localhost soft]# mysql -uroot -p123456

[root@localhost soft]# mysql -ucactiuser -ppwd123 cacti < /var/www/html/cacti/cacti.sql

調整配置文件

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

cacti-plugins 插件安裝 

[root@localhost soft]# unzip cacti-plugin-0.8.7e-PA-v2.6.zip

[root@localhost soft]# cd /var/www/html/cacti/

[root@localhost cacti]# patch -p1 -N < /soft/cacti-plugin-arch/cacti-plugin-0.8.7e-PA-v2.6.diff

[root@localhost cacti]# mysql -ucactiuser -ppwd123 cacti < /soft/cacti-plugin-arch/pa.sql

[root@localhost cacti]# vi include/global.php

建立任務調度

[root@localhost cacti]# su runct

[runct@localhost cacti]$ crontab -e

[runct@localhost cacti]$ crontab -l

[runct@localhost cacti]$ exit

Cacti 的 web 初始化

在瀏覽器輸入 http://your ip address/cacti/    登陸 cacti

Next

Next

Finish

帳號密碼：admin，admin

第一次要改密碼  這里改為pwd123

如果不出圖

修改settings-general rrdtool1.2.X 保存

好了，有圖了

Nagios安裝

準備帳號，目錄

[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/

開始安裝

[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頁面

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

生成 nagios 頁面訪問賬號

[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

帳號：admin                   密碼：123

Nagios 的 CGI 配置文件

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

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

測試 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

漢化（選做）

[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 插件安裝

[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

插件裝好，監(jiān)控的localhost正常了

PHP 支持 JSON 擴展

[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]# phpize

Configuring for:

PHP Api Version:         20041225

Zend Module Api No:      20050922

Zend Extension Api No:   220051025

[root@localhost php-json-ext-1.2.1]# ./configure ;make ;make install

[root@localhost php-json-ext-1.2.1]# vi /etc/php.d/json.ini（新建）

[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

查看網(wǎng)頁，出來json成功

ndoutils 安裝

[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安裝

[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 界面設置

登陸cacti

找到UserManagement

進去把勾plugin Management勾上，保存

點 settings下面的plugin management ，在點INSTALL，然后enable

裝好了

返回（console）菜單欄，點擊 configuration-------settings----NPC，修改一下三個參數(shù)（如下圖，cmd填寫上就行，命令會自動生成）

點擊NPC為OFF

啟動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

第一行報錯：是因為沒給ndo2db文件權限

[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''

這次是，數(shù)據(jù)庫有問題

[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;

執(zhí)行這些語句，在重啟nagios

[root@localhost soft]# service nagios restart

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

Ndo2db啟動成功，現(xiàn)在就可以看到NPC的數(shù)據(jù)了。
