解决linux-mysql 登录时,报异常:Access denied for user 'root'@'localhost'
第一步:停服务/etc/init.d/mysql stop
或者
service mysqld stop
第二步:跳过密码验证执行命令行:# /usr/bin/mysqld_safe --skip-grant-tables报:151104 09:07:56 mysqld_safe Logging to '/var/lib/mysql/iZ23dq2wm0jZ.err'.151104 09:07:56 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql第三步:无密码登录
执行命令行:mysql -u root第四步:授权
mysql>
grant all privileges on *.* to 'root'@'localhost' identified by 'root' with grant option;
关键词解释:root'@'localhost:是用户root:是密码问题一:发现无密码条件下,没有授权的写权限
The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
解决方法:mysql> set global read_only=0;//(关掉新主库的只读属性)mysql>flush privileges;再次执行第四步授权语句:grant all privileges on *.* to 'root'@'localhost' identified by 'root' with grant option;
mysql>set global read_only=1;//(读写属性)
mysql>flush privileges;(注意刷新是必须项)
第五步:重启数据库
/etc/init.d/mysql restart或者
service mysqld restart
