前言
本文介紹如何在centos 7.5上安裝Rancher
設(shè)置主機(jī)名
hostnamectl set-hostname node1
如果有多臺主機(jī)，可根據(jù)自己的情況設(shè)置
操作步驟
- 安裝docker
yum install -y wget
wget https://download.docker.com/linux/static/stable/x86_64/docker-17.03.2-ce.tgz
chmod +x docker/*
cp docker/* /usr/local/bin
- 設(shè)置開機(jī)啟動
cd /usr/lib/systemd/system
cat > docker.service <<"EOF"

EOF
systemctl restart docker
systemctl enable docker
- 設(shè)置國內(nèi)鏡像
mkdir /etc/docker/
cat > /etc/docker/daemon.json <<"EOF"
{
"registry-mirrors": ["https://registry.docker-cn.com"]
}
EOF
systemctl daemon-reload
systemctl restart docker
- 啟動rancher ui
docker run -d --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher
-
