myweb连接mysql失败 #7

Closed Jacarlianda closed 1 month ago

Jacarlianda commented 4 years ago

1.3.3 myweb-rc.yaml 镜像用的mysql-connector-java-5.1.37.jar，不兼容1.3.2 mysql-rc.yaml默认镜像 mysql 8，导致连接失败，需要将1.3.2 mysql-rc.yaml 指定mysql5.7版本。

我也遇到这个问题了，改成5.7解决。

我在有3个公网IP的ECS搭建了集群，也采用了mysql 5.7版本。myweb pod在node2, mysql pod在node1. 只能在node2节点访问web才有效，访问时出现错误，好像是不能识别mysql服务。 Error:com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

请使用 mysql 5.7版本测试，谢谢
