$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "redhat";
$database_port = "3306";
$database_ssl = false;
安装rrdtool以生成图像
[[email protected] src]# yum -y install rrdtool rrdtool-devel rrdtool-php rrdtool-perl
[[email protected] src]# yum -y install gd gd-devel php-gd ---rrdtool绘制图像需要的图形库
安装snmp服务
[[email protected] cacti]# yum -y install net-snmp net-snmp-utils php-snmp net-snmp-libs

报错
MySQL TimeZone Support ERROR: Your Cacti database login account does not have access to the MySQL TimeZone database. Please provide the Cacti database account "select" access to the "time_zone_name" table in the "mysql" database, and populate MySQL‘s TimeZone information before proceeding
**bash环境下执行 mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql
mysql环境下
mysql> use mysql;
mysql> GRANT SELECT ON mysql.time_zone_name TO [email protected];
mysql> flush privileges;**
