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;**
