总结一句话:权限问题。那怎么授权?
第一步:停服务
命令行:
/etc/init.d/MysqL stop
如果不行,就执行下一行:
service MysqLd stop
报:
Stopping MysqLd: [ OK ]
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
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;
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
service MysqLd stop
报:
Stopping MysqLd: [ OK ]
service MysqLd start
报:
Starting MysqLd: [ OK ]
或者
service MysqLd restart
