在RedHat5.5上用rpm安装MySQL 5.6装好mysql之后 见 http://www.linuxidc.com/Linux/2011-10/44882.htm用mysqladmin修改密码(mysqladmin –u root password “mysql”)提示mysqladmin:Can"t turn off logging; error: "Access denied; you need the SUPER privilege forthis operation"解决办法:修改mysql登录设置vi /etc/my.cnf (我们发现etc下没有my.cnf文件)通过查询知道,安装完MySQL 后,/etc/my.cnf 文件默认是不存在的,可以在/usr/share/doc/MySQL-servercommunity下找到my-huge.cnf 、my-innodb-heavy-4G.cnf 、my-large.cnf 、mymedium.cnf 、my-small.cnf 等文件,根据内存大小将其中合适你机器配置的文件拷贝到/etc/my.cnf(一般应用选mymedium.cnf即可)编辑my.cnf文件在[mysqld]段中加入 skip-grant-tables保存之后重启mysql服务/etc/rc.d/init.d/mysql restart重启mysql服务之后修改mysql密码[root@shiyue]# mysqlWelcome to the MySQL monitor.

Bye 退出mysql之后把刚修改的配置文件改回来(vi /etc/my.cnf)重启mysql服务mysql-u root -p登录mysql登陆成功! 再通过navicat连接mysql数据库,提示Can"t get hostname for your address 解决方法还是修改my.cnf文件,在[mysqld] 下面添加一行:skip-name-resolve,保存重启mysql(/etc/init.d/mysql restart) 赋权:Mysql –u root –p mysqlShow databasesUse mysqlgrant all on *.* to "root"@"192.168.1.254"identified by "mysql";quit 好重新用navicat进行连接,OK,测试通过!RedHat下MySQL 5.6 安装、维护Ubuntu下单机安装MongoDB并测试相关资讯 MySQL教程 Navicat
