使用
开启 mysqld 服务即可
systemctl start mysqld
初始密码在日志中
grep "A temporary password" /var/log/mysqld.log
示例输出
[root@centos7_vm ~]# grep "A temporary password" /var/log/mysqld.log
2020-04-14T03:02:22.204287Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: f安全
首次安装MySQL之后，执行 mysql_secure_installation 命令以保护MySQL服务器。它会提示您几个问题，我们建议每个问题都回答（y）。
示例
Enter password for user root:
The existing password for the user account root has expired. Please set a new password.
New password:
Re-enter new password:
Change the password for root ? ((Press y|Y for Yes, any other key for No) : n
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
其他
用上面修改后的密码登录即可
mysql -uroot -p
修改密码
ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';
安全问题不能将密码设置得太简单了
Your password does not satisfy the current policy requirements
SHOW VARIABLES LIKE 'validate_password%';
+--------------------------------------+--------+
| Variable_name | Value |
+--------------------------------------+--------+
| validate_password.check_user_name | ON |
| validate_password.dictionary_file | |
| validate_password.length | 8 |
| validate_password.mixed_case_count | 1 |
| validate_password.number_count | 1 |
| validate_password.policy | MEDIUM |
| validate_password.special_char_count | 1 |
+--------------------------------------+--------+
SET GLOBAL validate_password.length = 4;
SET GLOBAL validate_password.number_count = 0;
SET GLOBAL validate_password.special_char_count = 0;
SET GLOBAL validate_password.mixed_case_count = 0;
SET GLOBAL validate_password.policy = LOW;
SET GLOBAL validate_password.check_user_name = OFF;
flush privileges;
改完后就可以用 root 这种简单的密码了，不过不安全
