安装sqli-labs时，mysql 8 报错解决-Toy模板网

这篇具有很好参考价值的文章主要介绍了安装sqli-labs时，mysql 8 报错解决。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

首先执行命令Setup/reset Database for labs时，mysqlsql时报错：

SETTING UP THE DATABASE SCHEMA AND POPULATING DATA IN TABLES:

Warning: mysql_connect(): Server sent charset (255) unknown to the client. Please, report to the developers in D:\develop\networkSecurity\phpStudy\PHPTutorial\WWW\sqli-labs\sql-connections\setup-db.php on line 29

Warning: mysql_connect(): Server sent charset unknown to the client. Please, report to the developers in D:\develop\networkSecurity\phpStudy\PHPTutorial\WWW\sqli-labs\sql-connections\setup-db.php on line 29
[*]...................Could not connect to DB, check the creds in db-creds.inc: Server sent charset unknown to the client. Please, report to the developers

由错误可知是mysql 8的编码问题。

解决为修改mysql编码为utf8：

1、打卡mysql 8安装目录下的data文件夹，找到my.ini

2、修改两处my.ini中的配置：

character-set-server= utf8

default-character-set=utf8

重启mysql，然后再次执行Setup/reset Database for labs，还是报错：

SETTING UP THE DATABASE SCHEMA AND POPULATING DATA IN TABLES:

Warning: mysql_connect(): The server requested authentication method unknown to the client [caching_sha2_password] in D:\develop\networkSecurity\phpStudy\PHPTutorial\WWW\sqli-labs\sql-connections\setup-db.php on line 29

Warning: mysql_query(): MySQL server has gone away in D:\develop\networkSecurity\phpStudy\PHPTutorial\WWW\sqli-labs\sql-connections\setup-db.php on line 42

Warning: mysql_query(): Error reading result set's header in D:\develop\networkSecurity\phpStudy\PHPTutorial\WWW\sqli-labs\sql-connections\setup-db.php on line 42

着重看标红的地方，授权有问题。

解决办法还是修改my.ini配置文件：

default_authentication_plugin=mysql_native_password

再次重启mysql8并执行Setup/reset Database for labs，可以看到数据库已经创建成功了：

[*]...................Old database 'SECURITY' purged if exists

[*]...................Creating New database 'SECURITY' successfully

[*]...................Creating New Table 'USERS' successfully
