Linux under Installation configuration cacti monitoring

Cacti is a set of graphical analysis tools for network traffic monitoring based on PHP,MYSQL,SNMP and RRDtool development.

Environment Construction:

Cacti Service side: 192.168.20.20

Cacti Client: 192.168.20.30

The steps for cacti installation configuration are as follows:

1. First to install the Epel extension source

Yum Install Epel-release

2. (Install lamp environment) install httpd, PHP, MySQL

Yum install-y httpd php php-mysql mysql mysql-server mysql-devel php-gd libjpeg libjpeg-devel libpng libpng-devel

3. Install cacti, NET-SNMP, RRDtool

Yum install-y cacti Net-snmp net-snmp-utils rrdtool

4. Start the service:

/etc/init.d/mysqld start/etc/init.d/httpd start/etc/init.d/snmpd Start

5. Edit the httpd configuration file

Vi/etc/httpd/conf.d/cacti.conf

Change "Deny from all" to "Allow from all"

/ETC/INIT.D/HTTPD restart

6. Import data Create cacti Library

# mysql-uroot-e "CREATE database Cacti"

Create cacti User

# MYSQL-UROOT-E "Grant all on cacti.* to ' cacti ' @ ' 127.0.0.1 ' identified by ' cacti ';"

Import SQL file

# Mysql-uroot Cacti </usr/share/doc/cacti-0.8.8b/cacti.sql

7. Edit the cacti configuration file

vi/usr/share/cacti/include/config.php changes as follows:

$database _type = "MySQL"; $database _default = "cacti"; $database _hostname = "127.0.0.1"; $database _username = "cacti"; $ Database_password = "cacti"; $database _port = "3306"; $database _ssl = false;

8. Web Access cacti and installation

Click "Next" and "Finish" at two.

Enter Admin Admin login, reset the new password;

9. Execute poller.php, generate graphics, join scheduled Tasks

/usr/bin/php/usr/share/cacti/poller.php

Add Cron Task

CRONTAB-E Increase:

*/5 * * * */usr/bin/php/usr/share/cacti/poller.php

The following steps 10-12 need to be done on the client that needs to be monitored:

10. Install SNMP

Yum Install-y Net-snmp

11. Modify Snmpd.conf

# vi/etc/snmp/snmpd.conf

Modify Syslocation and Syscontact, where syslocation can write the ip,syscontact of the monitoring client to write the admin mailbox

Syslocation 192.168.20.30syscontact Root [email protected]

12. Start SNMP

Service SNMPD Start

13. Login to the Cacti management background, click Console, then click Device, in the upper right corner, click "Add"

Description Write monitoring client IP or customize a name

Hostname Write monitoring Client IP

Host Template Select Ucd/net SNMP Host

Version 2 of SNMP version selected

Click Create in the lower right corner

Finished installing Cacti Monitor, do not see the network card information, the workaround:

Editing a monitored client/etc/snmp/snmpd.conf file

View SystemView included. 1.3.6.1.2.1.1

Modified to:

View SystemView included. 1.3.6.1.2.1

Then restart the SNMPD service;

#/ETC/INIT.D/SNMPD Restart
