Dependent Package Installation:

Yum install-y cairo-devellibxml2-devel pango-devel pango libpng-devel freetype freetype-devellibart_lgpl-devel Pear Pear-devel

"Install configuration SNMP"

Cacti uses SNMP to fetch data from the remote host. As a result, all hosts with SNMP services enabled can be cacti monitored

Yum-y Install NET-SNMP net-snmp-utils net-snmp-devel #安装

Cp/etc/snmp/snmpd.conf/etc/snmp/snmp.conf

Edit File Modification vi/etc/snmp/snmp.conf

Modify 41st Line default to 127.0.0.1

Com2sec notconfiguser 127.0.0.1 Public

Change line 62nd SystemView to all

Access Notconfiggroup "" Any noauth exact none none

Uncomment 85th Line

View all included. 1 80

/ETC/INIT.D/SNMPD Start #启动服务

Chkconfig snmpd on #开机自启动

"Install RRDtool"

 

Cacti uses RRDtool to store data, one of the most admirable features is its drawing capabilities

Yum-y install NTP vim-enhanced gcc gcc-c++gcc-g77 Flex bison autoconf automake bzip2-devel ncurses-devel zlib-devellibjpe G-devel libpng-devel libtiff-devel freetype-devel libxpm-develgettext-devel pam-devel libxml2-devel glib pango-devel Pango Cairo-devellibart_lgpl-devel

"Install the polling spine(not required)"

For efficiency reasons, it is slower to use the cmd.php polling device when collecting data in large quantities, and the acquisition frequency of 1 minutes and 1 times may not complete polling of all machines. In order to optimize, we use the officially recommended spine for efficient polling.

Yum Install Openssl-devel Mysql-develnet-snmp-devel

Db_database cacti
Db_user cacti
Db_pass cacti

Db_port 3306
Db_preg 0

#设置mysql中用于cacti的数据库的户登录名. The following is again created

"Install Cactid"

Cactid is written in C to replace the cmd.php to produce pictures, the performance is stronger, but need to compile the installation. First install several devel packages required for compiling Cactid:

Yum-y Install net-snmp-devel mysql-devel OPENSSL-DEVELGCC Libtool

Download Cacti,cacit official website: http://www.cacti.net/downloads/

cd/var/www/html/

Configuration Database

create cacti users and databases in MySQL (previously spine.conf configured as cacti users):

Mysql-uroot-p

mysql> Insert Intomysql.user (Host,user,password) VALUES (' localhost ', ' cacti ', password (' cacti '));

mysql> Insert Intomysql.user (Host,user,password) VALUES (' 127.0.0.1 ', ' Cacti ', password (' cacti '));

mysql> CREATE database cacti;

mysql> use cacti;

Mysql> Source/var/www/html/cacti/cacti.sql;

mysql> flush Privileges;

Mysql> grant all privileges on Cacti.*to cacti@localhost identified by ' cacti ';

Mysql> grant all privileges on Cacti.*to cacti@127.0.0.1 identified by ' cacti ';

mysql> flush Privileges;

Mysql> exit

Add cacti Users:

Useradd cacti

echo "cacti" |passwd--stdin cacti

Chgrp-r cacti/var/www/html/cacti/

Chown-r Cacti/var/www/html/cacti/rra

Chown-r Cacti/var/www/html/cacti/log

let cacti's poller fetch data at a fixed time:

Vi/etc/crontab

*/1 * * * */usr/bin/php/var/www/html/cacti/poller.php >/dev/null 2>&1

Service Crond Restart

#cat/var/spool/cron/root

Edit the configuration file (if you use cacti users instead cacti users):

vi/var/www/html/cacti/include/config.php

$database _type = "MySQL";

$database _default = "cacti";

$database _hostname = "localhost";

$database _username = "cacti";

$database _password = "cacti";

$database _port = "3306";

Vi/etc/selinux/config

Change the selinux=enforcing into a permissive.
