解決辦法.
/etc/init.d/mysql stop #停止mysql服務,/etc/init.d/mysqld
stop 現在是這個命令
/usr/bin/mysqld_safe
--skip-grant-tables 跳過命令啓動
再開一個ssh
[root@host-192-168-14-59
~]# mysql
mysql>
use mysql
// mysql>update user set password=password("123456") where user="root"; #在5.7中已經沒有password這個字段了，password字段改成了
authentication_string所以現在是用:
mysql>update
mysql.user set authentication_string=password('123456') where user='root' ; #賬號 root 密碼 123456
mysql>flush privileges;
mysql>exit
然後:
[root@host-192-168-14-59
~]# ps -A | grep mysql
7775 pts/0 00:00:00 mysqld_safe
7913 pts/0 00:00:00 mysqld
[root@host-192-168-14-59 ~]# kill -9 7775 7913
正常啓動
MySQL：/etc/init.d/mysqld start
mysql -u root -p
OK
ps:
在進到mysql裏面後,第一次操作的時候出現:
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
mysql> SET PASSWORD = PASSWORD('123456');
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
這是需要調整一個全局變量:
mysql> set global validate_password_policy=0;
validate_password_policy有以下取值：
Policy Tests Performed
0 or LOW Length
1 or MEDIUM Length; numeric, lowercase/uppercase, and special characters
2 or STRONG Length; numeric, lowercase/uppercase, and special characters; dictionary file
mysql> SET PASSWORD = PASSWORD('12345678');
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> ALTER USER 'root'@'localhost'PASSWORD EXPIRE NEVER;
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> exit
Bye
這樣退出,再進就好了.
