20220211 seafile客户端部分资料库无法同步
解决方法：
- 找找找，抓到api错误，但还是找不到原因；
- 将seafile由8.0升级到9.0；
- 升级后报mysql无权限->进入mysql容器，use db后，通过报错，采用chmod + R，解决权限问题；
- seafile-mc依然无法启动，修改启动脚本，寻找问题，发现优点懵逼，遂屏蔽报错代码，暂启动seafile。
20181106 seafile docker无法启动问题
Centos7重启后seafile docker容易无法启动。docker logs seafile错误如下：

解决方法：
找了很久，没有找到解决方法。
暂时用以下方法，假装解决了这个问题。
/home/tools/seafile.sh docker stop seafile docker pull seafileltd/seafile:latest docker rm -f seafile docker run -d --name seafile -e SEAFILE_SERVER_HOSTNAME=seafile.abc.com --restart always -v /mnt/vdb/opt/seafile-data:/shared -p 9001:80 seafileltd/seafile:latest
