建议用这种办法更加方便第一种我试过更加麻烦

#clone src
git clone https://github.com/docker/swarmkit.git
#不用 cd 进去目录
docker pull golang:1.12

#这一步所有要加入swarmkit集群的节点都要

Initialize the first node

swarmd --state-dir /tmp/node-mgmt-01 --listen-control-api /tmp/mgmt-01.sock --hostname mgmt-01 >/tmp/mmt-01.log 2>&1 &

swarmctl 查看集群信息

加入到环境变量吧

看到有三台机器了

停机维护 swarmctl node drain 节点id
恢复 swarmctl node activate 节点id

得用go1.12(docker) 不然编译有问题还是用docker方便安装文件的老是有问题呢

tatus: Downloaded newer image for golang:1.8
WARNING: IPv4 forwarding is disabled. Networking will not work.

解决办法：
# vi /etc/sysctl.conf
或者
# vi /usr/lib/sysctl.d/00-system.conf
添加如下代码：
net.ipv4.ip_forward=1

重启network服务
# systemctl restart network

查看是否修改成功
# sysctl net.ipv4.ip_forward

如果返回为“net.ipv4.ip_forward = 1”则表示成功了

这时，重启容器即可。
