容器部署时报warning

服务器问题
1

使用docker-compose.yml通过docker-compose部署，启动时报错：

seafile-docs-mysql | 2019-06-04  9:30:57 159 [Warning] Access denied for user 'root'@'172.18.0.4' (using password: YES)

但是172.18.0.4是容器：seafileltd/seafile-docs:latest的IP，非常不解的是，数据库在seafile-docs-mysql (172.18.0.3)容器中，为啥要去连seafileltd/seafile-docs:latest容器的数据库IP？

这个报错不是链接docs上得mysql，而是mysql拒绝来自docs得链接请求，你没有理解报错的意思。

了解了。没有问题了，谢谢

记录个吧：这个好像是由于默认设置的数据库连接时间超级短，如果数据库没初始完成seafile就去连接的话，就会报错；解决方法：增加超时时间 7~30s即可
在 seafile:environment:- DB_ROOT_PASSWD=db_dev 一行下面增加如下：

  • DB_CONNECT_TIMEOUT=30000
