Cacti安装

[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/

添加个用来读写监测数据的用户账号：runct，调整子目录rra/,log/的属主权限

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

导入cacti.sql，建立数据库、表结构

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

mysql> create database cacti default character set utf8;

Query OK, 1 row affected (0.00 sec)

mysql> grant all on cacti.*  to  cactiuser@localhost identified by 'pwd123';

Query OK, 0 rows affected (0.00 sec)

mysql> quit

Bye

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

调整配置文件

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

30 $database_password = "pwd123";

cacti-plugins 插件安装 

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

[runct@localhost cacti]$ crontab -e

[runct@localhost cacti]$ crontab -l

*/5 * * * * /usr/bin/php /var/www/html/cacti/poller.php &> /dev/null

[runct@localhost cacti]$ exit

Cacti 的 web 初始化

在浏览器输入 http://your ip address/cacti/    登陆 cacti

 

Next

 

Next

 

Finish

帐号密码：admin，admin

第一次要改密码  这里改为pwd123

 

如果不出图

 

修改settings-general rrdtool1.2.X 保存

 

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

New password:

Re-type new password:

htpasswd: password verification error（2次输的不一样，在执行一次命令）

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]# 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）

extension=json.so                                                                

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

<?php

phpinfo();

phpinfo(INFO_GENERAL);

phpinfo(1);

?>

 

[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

102 db_name=cacti

111 db_prefix=npc_

120 db_user=cactiuser

121 db_pass=pwd123

163 debug_level=1

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

247 # Uncomment the line below  you're running Nagios 3.x

248 broker_module=/usr/bin/ndomod-3x.o config_file=/usr/local/nagios/etc/ndomod.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

  46 $plugins[] = 'npc';

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

Jul  5 17:30:27 localhost nagios: ndomod: Could not open data sink!  I'll keep trying, but some output may get lost...

Jul  5 17:30:27 localhost nagios: Event broker module '/usr/bin/ndomod-3x.o' initialized successfully.

Jul  5 17:30:27 localhost nagios: Finished daemonizing... (New PID=12009)

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

Jul  5 17:40:52 localhost nagios: ndomod: Successfully connected to data sink.  0 queued items to flush.

Jul  5 17:40:52 localhost nagios: Event broker module '/usr/bin/ndomod-3x.o' initialized successfully.

Jul  5 17:40:52 localhost nagios: Finished daemonizing... (New PID=12381)

Ndo2db启动成功，现在就可以看到NPC的数据了。
