我的机器上运行着 mysql的无登录变体。所以我只是输入mysql获取 mysql 客户端 shell。

不,当我试图让 SchemaSpy 连接到 mysql 时它失败了:

# try with my user:
java -jar schemaSpy_5.0.0.jar -t mysql -dp /home/bodo/bin/mysql_conn/mysql-connector-java-5.1.49/mysql-connector-java-5.1.49-bin.jar -host localhost -u bodo -db ibo -o /home/bodo/bin/schemaspy/ibo
Using database properties:
  [schemaSpy_5.0.0.jar]/net/sourceforge/schemaspy/dbTypes/mysql.properties
Thu Feb 10 17:01:05 CET 2022 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

# try without user does not work at all
bodo@bodo-work:~/bin/schemaspy$ java -jar schemaSpy_5.0.0.jar -t mysql -dp /home/bodo/bin/mysql_conn/mysql-connector-java-5.1.49/mysql-connector-java-5.1.49-bin.jar -host localhost -db ibo -o /home/bodo/bin/schemaspy/ibo

net.sourceforge.schemaspy.Config$MissingRequiredParameterException: Required parameter '-u' was not specified.

所以重点是Access denied for user 'bodo'@'localhost' (using password: NO)

我该如何调试这个或者我需要如何更改我的 MySQL 设置才能让 SchemaSpy 运行?

我通过授予有问题的用户访问数据库并使用密码解决了连接问题。

当你遇到这种情况时:

mysql -u bodo
ERROR 1045 (28000): Access denied for user 'bodo'@'localhost' (using password: NO)

你没有匿名用户

这可以帮助:

  • ALTER USER 'bodo'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your_pssw';
  • GRANT ALL PRIVILEGES ON *.* TO 'bodo'@'localhost' WITH GRANT OPTION;

不要忘记FLUSH PRIVILEGES;

然后你应该能够使用:

mysql -u bodo -p ibo -h localhost
Enter password:

You can turn off this feature to get a quicker startup with -A
