主要是5.7的很多操作和以前版本不一样,所以踩了很多坑。
my.cnf
里找到参考:https://www.jianshu.com/p/93fa9de59ac1
最终发现 mysql5.7的配置文件的结构是:
.
├── conf.d
│ ├── mysql.cnf
│ └── mysqldump.cnf
├── debian.cnf
├── debian-start
├── my.cnf -> /etc/alternatives/my.cnf
├── my.cnf.fallback
├── mysql.cnf
└── mysql.conf.d
├── mysqld.cnf
└── mysqld_safe_syslog.cnf
在 mysqld.cnf
文件中,有这个 bind-address
配置。
改变
bind-address = 127.0.0.1
为
bind-address = 0.0.0.0
update mysql.user set authentication_string=password(‘123qwe‘) where user=‘root‘;
flush privileges;
quit;
service mysql restart

1、root用户登录到mysql数据库代码示例:
/usr/local/mysql/bin/mysql -u root -p (输入密码进入mysql)
2、进入mysql,输入:
代码示例:
use mysql;
3、查看user表的情况
代码示例:
SELECT Host,User FROM user;
//指明主机名称,“%”表示匹配所有字符串
4、
代码示例:
UPDATE user SET Host = '%' WHERE User= 'root' LIMIT 1;
5、输入如下命令让刚才设置的命令生效
代码示例:
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
注意,在mysql 命令行形式下一定要输入";"
按照前面五个步骤完成之后,通过控制台输入:
代码示例:
[root@linux ~]# mysql -h localhost -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
不让这么连接数据库
原因:是因为host对应的user字段是空的,我们需要将其改为root即可
代码示例:
mysql> select host,user from user;
+-----------+------+
| host | user |
+-----------+------+
| % | root |
| 127.0.0.1 | root |
| linux | |
| linux | root |
| localhost | |
+-----------+------+
5 rows in set (0.00 sec)
解决办法一:
代码示例:
mysql> update user set user='root' where host='localhost';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
解决办法二:
将localhost改为本机的IP地址,则能够识别了。
代码示例:
[root@linux ~]# mysql -h 172.16.42.68 -u root -p
Enter password:
