拆解 cacti的数据包
将cacti 搬移致/var/www/html
tar -zxvf cacti-0.8.7g.tar.gz -C /var/www/htmlcd /var/www/htmlmv cacti-0.8.7g/ cacti# mysqld_safe --user=mysql &# mysqladmin –u root -p password
配置mysql
CREATE DATABASE cacti;
//若只监控本机，这句就够了
grant all privileges on cacti.* to cacti@localhost identified by 'cacti';
#grant all privileges on cacti.* to cacti@127.0.0.1 identified by 'cacti';
//否则，要在那台服务器上的mysql中授权允许cacti主机的连接
grant Process,Super on *.* to 'cacti'@'172.16.1.6' identified by 'cacti';#grant Process,Super on *.* to 'cacti'@'monitor.cactimon.com' identified by 'cacti';flush privileges;
实验过程中，很多人出现graps下为空表，或无表，大多是因为这里未正确授权，导致无法连接到数据库造成的，可以用以下命令测试是否可以正常连接
mysql -h 192.168.0.1 -ucacti -pcacti
# use mysql;# 直接插入# insert into user(Host,User,Password) values ('172.16.1.6','cacti','cacti');# 更新# update user set host='monitor.cactimon.com' where host='172.16.1.6';# update user set password=password('cacti') where host='monitor.cactimon.com';# 删除# delete from user where user='cacti'; cacti 网页默认登陆密码：admin admin
无法登陆：
mysql>use cacti；mysql>update user_auth set password=md5("新密码") where username='admin'; ################################
