system version

cat /etc/system-release

AlmaLinux release 9.1 (Lime Lynx)

disabled SELinux

sudo vim /etc/selinux/config

修改为

SELINUX=disabled

AlmaLinux dnf source

aliyun mirror

sudo sed -e 's|^mirrorlist=|#mirrorlist=|g' \-e 's|^# baseurl=https://repo.almalinux.org|baseurl=https://mirrors.aliyun.com|g' \-i.bak \/etc/yum.repos.d/almalinux*.reposudo dnf makecache
sudo dnf update -y

xrdp

1.推荐安装xrdp

sudo dnf install -y epel-release && sudo dnf install -y xrdp

echo gnome-session > ~/.xsessionsudo systemctl start xrdp && sudo systemctl enable xrdp
sudo systemctl status xrdpsudo firewall-cmd --permanent --add-port=3389/tcp
sudo firewall-cmd --reloadsudo netstat -antup | grep xrdp

2.参考
注意：启动xrdp服务和系统防火墙放行监听端口后，需要注销（Log Out）当前用户登录才能在另一台机器上通过xrdp登录，实在不行的话，直接重启，然后用xrdp方式登录

Install docker

docker docs

sudo dnf remove docker \docker-client \docker-client-latest \docker-common \docker-latest \docker-latest-logrotate \docker-logrotate \docker-engine \podman \runc

sudo dnf config-manager \--add-repo \https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo # docker-ce mirrorssudo dnf makecache

sudo dnf install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin

还需设置docker 国内镜像 (images) 源

sudo systemctl start docker && sudo systemctl enable docker
sudo systemctl status docker
