描述
Azure的MSYQL服务器开启在强制SSL,我在执行语句时日志报“ERROR 9002 (28000): SSL connection is required. Please specify SSL options and retry”,--ssl=required参数已经添加过了,请问这个如何解决谢谢。

重现
通过arcerhy执行SQL,选择【备份】

环境

  • 数据库: mysql
  • 版本: 5.6.47.0 MySQL Community Server (GPL)

错误日志:

备份功能是通过MySQL Slave复制协议实现的,以模拟从库的方式读取Binlog.
这个报错应该是Azure MySQL做了自定义,禁止了该行为.和--ssl参数无关的.

感谢您的解答
我尝试在Azure上把强制SSL关闭就可以正常备份,重新打开就会备份失败,所以我觉得这个对MySQL Slave并没有进行限制。另外,我看您的config.toml文件示例中有这[security],这个是做什么用的呢,我在里面加上了这些备份,但是似乎没有效果,依然是SSL connection is required那个错误。
[security]
skip_grant_table = true
#Path of file that contains list of trusted SSL CAs for connection with mysql client.
ssl-ca = "/opt/ca.pem"
#Path of file that contains X509 certificate in PEM format for connection with mysql client.
ssl-cert = "/opt/client-cert.pem"
#Path of file that contains X509 key in PEM format for connection with mysql client.
ssl-key = "/opt/client-key.pem"

既然关闭SSL可以备份, 说明协议是没问题的.
我检查了一下go-mysql包有SSL参数支持, 只是我没有测试环境,需要你提供一下详细的ssl设置.

另外,如果你熟悉golang的话,可以按如下方式测试:
参考 go-mysql 项目首页,该包是用来支持MySQL复制协议的.

  1. 复制项目首页的demo到新文件main.go
  2. import导入包"crypto/tls"
  3. 修改cfg到测试的Azure MySQL数据库
  4. syncer := replication.NewBinlogSyncer(cfg) 上面添加一行:
    cfg.TLSConfig = &tls.Config{InsecureSkipVerify: true}
  5. 之后运行该文件看是否有报错即可.

PS: [security]段可以设置到远程数据库的访问方式,如开启ssl安全访问.
或者开启skip_grant_table打开鉴权功能,goinception默认免密,因为其没有任何数据,只作为中间件存在的.

另外你可以测试--ssl本身,数据库已经开启了ssl的话, 该参数必须要设置的吧,不然应该无法连接到数据库的.
我可以复用该配置到备份功能.

我用上面的方法测试了一下,加上cfg.TLSConfig = &tls.Config{InsecureSkipVerify: true}这一行,即可正常获取到binlog数据,
如果不加的话,会提示显示下面的提示,所以我觉得那一行,还是有效果的。

[2020/12/18 08:04:32] [info] binlogsyncer.go:360 begin to sync binlog from position (mysql-bin.000012, 5524015)

接下来我应该怎么做,才能把tls.Config{InsecureSkipVerify: true应用起来呢?谢谢。

--ssl参数你设置的是什么

我在archery里的sql/engines/goinception.py设置的设置是--ssl=required
像是这样:

        sql_execute = f"""/*--user='{user}';--password='{password}';--host='{host}';--port={port};--execute=1;--ignore-warnings=1;{str_backup};--sleep=200;--sleep_rows=100;--ssl=required*/
                            inception_magic_start;
                            {set_session_sql}
                            use `{workflow.db_name}`;
                            {workflow.sqlworkflowcontent.sql_content.rstrip(';')};
                            inception_magic_commit;"""
        inception_result = self.query(sql=sql_execute)

更新了版本,可以试一下.
改动内容如下:

+       if s.opt.ssl != "" {
+               switch s.opt.ssl {
+               case "preferred", "true", "required":
+                       cfg.TLSConfig = &tls.Config{InsecureSkipVerify: true}
+               }
+       }
+

您好,备份成功了,回滚语句也可以正常下载了。我看日志里还有一些kill connection错误,麻烦看一下是否有影响吧。谢谢

这个可以忽略,只是断开binlog复制,我优化一下.

OK,那暂时没问题了。多谢
