Install Rancher server

1.pre-requirement:

sudo nmtui

# sudo hostnamectl set-hostname <hostname>
$ sudo hostnamectl set-hostname rancher01
$ sudo systemctl restart systemd-hostnamed

 sudo yum install openssh -y

2.docker:

$ sudo yum install yum-utils -y
$ sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo
$ sudo yum makecache fast

$ sudo yum install docker-ce

$ sudo groupadd docker
$ sudo usermod -aG docker <youruser>

$ getent group docker

$ systemctl start docker

$ sudo systemctl enable docker

注意上面的在centos7里面很简单就完成了，这里装一下*，所以加进去了，万一后面有用呢。

Install Rancher server

$ docker run -d --restart=unless-stopped -p 8080:8080 rancher/server:stable

 

$ docker run -d --name rancher-mysql --restart=unless-stopped -e MYSQL_ROOT_PASSWORD=<password> -e MYSQL_DATABASE=cattle mysql:5.7
$ docker run -d --restart=unless-stopped --link rancher-mysql:rancher-mysql -p 8080:8080 rancher/server:stable --db-host rancher-mysql --db-port 3306 --db-user root --db-pass <password> --db-name cattle

 

$ docker run -d -v <path>:/var/lib/mysql --restart=unless-stopped -p 8080:8080 rancher/server:stable

 

$ sudo firewall-cmd --zone=public --add-port=8080/tcp --permanent
$ sudo firewall-cmd --reload

 

$ sudo firewall-cmd --list-ports

Rancher 要检查ipv6：所以要enable it：

$ sudo sysctl -a | grep net.ipv6.conf.all.forwarding

 

net.ipv6.conf.all.forwarding=1

 

$ sudo reboot

last:
http://<your ip>:8080
