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 mysql restart
