机器节点准备：
|
|||
|
|
需要一台manager机器，内存和硬盘大一点，多台worker机器。
|
|||
|
|
1、安装alma Linux 9.3，设置主机名、静态IP。
|
|||
|
|
2、设置主机名。sudo hostnamectl status
|
|||
|
|
sudo hostnamectl set-hostname [swarm-manager01、swarm-worker01等等]
|
|||
|
|
3、设置静态IP，swarm mode需要使用静态IP，不能使用动态IP。
|
|||
|
|
sudo vim /etc/NetworkManager/system-connections/ens160.nmconnection
|
|||
|
|
...
|
|||
|
|
[ipv4]
|
|||
|
|
address1=92.168.31.251/24,192.168.31.1 （ip自己替换）
|
|||
|
|
dns=114.114.114.114;
|
|||
|
|
method=manual
|
|||
|
|
...
|
|||
|
|
|
|||
|
|
nmcli c reload # 重新加载配置文件
|
|||
|
|
nmcli c up ens160
|
|||
|
|
4、关闭防火墙，sudo systemctl stop firewalld
|
|||
|
|
sudo systemctl disable firewalld
|
|||
|
|
sudo systemctl disable --now firewalld
|
|||
|
|
sudo firewall-cmd --state
|
|||
|
|
5、关闭SELinux，sudo setenforce 0
|
|||
|
|
sudo sed -ri 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
|
|||
|
|
sudo sestatus
|
|||
|
|
6、主机系统时间同步配置，
|
|||
|
|
sudo yum install -y chrony
|
|||
|
|
sudo vim /etc/chrony.conf
|
|||
|
|
注释掉第三行原有的时间服务器地址，设置为阿里云的时间服务地址:
|
|||
|
|
# pool 2.almalinux.pool.ntp.org iburst
|
|||
|
|
pool ntp1.aliyun.com iburst
|
|||
|
|
....
|
|||
|
|
sudo systemctl enable --now chronyd
|
|||
|
|
sudo chronyc -a makestep
|
|||
|
|
|
|||
|
|
|
|||
|
|
Docker install
|
|||
|
|
|
|||
|
|
1、 sudo yum install -y yum-utils
|
|||
|
|
2、 sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
|
|||
|
|
3、 sudo yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
|
|||
|
|
4、 sudo usermod -aG docker $USER
|
|||
|
|
5、 newgrp docker
|
|||
|
|
6、 sudo systemctl enable docker.service
|
|||
|
|
7、 sudo systemctl enable containerd.service
|
|||
|
|
8、 sudo systemctl start docker
|
|||
|
|
9、 docker run hello-world
|
|||
|
|
|
|||
|
|
delete swarm
|
|||
|
|
On manager机器上，执行：docker swarm leave --force
|
|||
|
|
|
|||
|
|
Create a swarm
|
|||
|
|
On manager机器上
|
|||
|
|
1、 docker swarm init --advertise-addr 192.168.3.188
|
|||
|
|
记住输出的命令
|
|||
|
|
2、 docker info
|
|||
|
|
3、 docker node ls
|
|||
|
|
|
|||
|
|
On worker机器上
|
|||
|
|
在manager机器上执行docker swarm join-token worker可以再次获取token
|
|||
|
|
|
|||
|
|
1、docker swarm join --token xxx【刚才输出的命令】
|
|||
|
|
2、在manager机器上执行：docker node ls
