通过以上图,我要解决两个问题:
1.默认登录数据库,不需要密码,看到上述表得知,原因是root用户没有设置密码;
2.Cacti程序连接数据库对用的是cactiuser用户账号,在这里做出修改,提升数据库安全性。
mysql> update user set password=password("****") where user="root"; #更改root用户密码
Query OK, 3 rows affected (0.00 sec)
Rows matched: 3 Changed: 3 Warnings: 0
mysql>select host,user,password from user;

#请注意,cacti程序的host主机是localhost,对用此项修改密码才有效果;

数据库中修改了用户的密码,所以程序配置文件也要修改对应的账号。
# vi /var/www/html/include/config.php
$database_type = "mysql";
$database_default = "数据库名";
$database_hostname = "localhost";
$database_username = "用户名";
$database_password ="密码";
$database_port = "3306";
到此步为止,所有配置成功。
一个建议,root用户用于整个数据库系统管理,业务系统另建账户。
