mysql> set PASSWORD = PASSWORD(‘111111’);
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
添加远程访问权限
mysql> use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> update user set host=’%’ where user=‘root’;
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> select host,user from user;
±----------±----------+
| host | user |

| % | root |
| localhost | mysql.sys |

2 rows in set (0.00 sec)
create user ‘xxx’@’%’ identified by ‘123’; 这里 @‘%’ 表示在任何主机都可以登录
log_timestamps=SYSTEM #此设置解决mysql日志时间和实际系统时间相差8小时，因为默认使用的是美国时间
default-time-zone = “+08:00” 修改时区为东八区
log-error=/var/log/mysqld.log 设置Mysql日志文件位置，
设置一下时间 然后重启数据库
为了安全一般不给root远程访问权限 可以再创建一个别的用户，并给他远程访问权限
grant all privileges on . to anycfs@’%’ identified by ‘anycfs123’;
flush privileges;
