基础设置问题

更换头像镜像源

因为默认的镜像源在国内是无法访问的,会导致浏览器tab页面一直卷圈圈(逼死强迫症啊),所以需要替换一下镜像源
系统/博客设置/Gravatar镜像源/设置为//gravatar.loli.net/avatar/

Halo升级问题

官方升级文档
直接按照官方迁移文档将1.4.3迁移到1.4.8使用docker部署出现如下问题

docker容器无法访问宿主主机问题

• https://bbs.halo.run/?q=docker mysql

• docker容器默认是bridge的适合h2数据库无法访问到宿主主机docker run -it -d --name halo -p 8090:8090 -v ~/.halo:/root/.halo --restart=always halohub/halo

• 改用host网络创建容器即可 docker run -it -d --net host --name halo -p 8090:8090 -v ~/.halo:/root/.halo --restart=always halohub/halo

因为使用本机的端口和ip,那么-P或者-p可能出现如下警告
