搭建cacti

1、搭建lamp环境
yum -y install httpd mariadb mariadb-server mariadb-devel php php-mysql php-gd php-pear gd gd-devel
systemctl start httpd && systemctl enable httpd
systemctl start mariadb && systemctl enable mariadb

2、安装绘图工具和snmp组件

yum -y install rrdtool rrdtool-devel rrdtool-perl rrdtool-php net-snmp-*
systemctl start snmpd && systemctl enable snmpd

3、数据库创建cacti用户及库 

mysql -uroot -p
> create database cacti character set utf8 collate utf8_bin;
> grant all on cacti.* to cacti@localhost identified by "1234";
> flush privileges;

为保证cacti用户也可以登录数据库，若出现本地无法登录情况，解决方式如下：

mysql -u root -p  #使用root账户登录数据库；

select user,host from mysql.user;   #有空用户名称占用导致本地无法登录远程可登录

drop user ''@localdrop user;

drop user ''@localhost.localdomain;host;

4、下载安装cacti并修改配置

wget https://www.cacti.net/downloads/cacti-0.8.8h.tar.gz
tar -xf cacti-0.8.8h.tar.gz
mv cacti-0.8.8h /var/www/html/cacti
chown -R root.root /var/www/html/cacti
vim /var/www/html/cacti/include/config.php

mysql -ucacti -p1234 cacti < /var/www/html/cacti/cacti.sql
