Rancher安装

1.防火墙设置

firewall-cmd --add-port 80/tcp --permanent
firewall-cmd --add-port 443/tcp --permanent
firewall-cmd --reload

2. 安装Docker

yum install docker -y
systemctl start docker

3. 安装Rancker

docker pull rancher/rancher:stable
hostnamectl set-hostname rancher
mkdir -p /home/rancher/rancher
mkdir -p /home/rancher/auditlog
docker run -d --privileged --restart=unless-stopped -p 80:80 -p 443:443 -v /home/rancher/rancher:/var/lib/rancher -v /home/rancher/auditlog:/var/log/auditlog --name rancher rancher/rancher:stable

4. 在RockyLinux9上通过docker安装Rancher一直不成功，日志显式反复启动，一直在等待这个接口可用：

Waiting for server to become available: Get "https://127.0.0.1:6444/version?

原因是RockyLinux9上得iptable没配置好，通过下列命令可解决：

sudo modprobe iptable_filter
sudo modprobe iptable_nat
sudo modprobe iptable_mangle
