docker 迁移/var/lib/docker/overlay2导致 /tmp Permission denied 问题修复

docker logs -f mysql 日志如下提示  Permission denied 错误.

晚上加班脑袋糊涂，一直以为是主机的 /tmp没权限，主机执行 chmod 1777 /tmp 无效。

 

直接找到 overlay2 目录执行

#chmod 1777 ./{容器Id}/diff/tmp

chmod 1777 ./e284dc4e33b837c00dc256b925599ce2e3c24ec458c044f27051dc82ae5d44cc/diff/tmp

　

重启 docker 服务，重启docker 容器，正常。

 

折腾一晚上，睡觉早上起来头脑清新，半小时搞定。昨晚上折腾一晚上都没搞好，还是不能加班。。。
