最近启动了一个容器,容器外联同服务器内其他容器的 mysql,结果提示无法连接
因为没有 mysql,直接用 python 脚本测试连接的
报错提示
pymysql.err.OperationalError: (2003, "Can't connect to MySQL server on '172.17.0.1' ([Errno 113] Host is unreachable)")
目前已经排除错误
1.mysql 防火墙已开,可以从部分容器内访问 mysql,也可以本地用 Navicat 访问 mysql,但是新启动的容器就是不行
2.无法访问 mysql 的容器是可以 ping 到 mysql 容器端口的
求各位大神给个解决思路.....
