【问题描述】：
我看到与described here 和here 相同的问题。我已经尝试了在这两种情况下有效的所有方法 - 我仍然看到相同的行为。有人可以提供我可以尝试的替代方案吗？
我的设置：
我正在运行 3 个 Centos 7.2 盒子。在所有机器上运行的网络时间协议 (ntpd)。一切都已经 yum 更新了。以下是一些详细信息：
Linux version 3.10.0-327.28.2.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.3 20140911 (Red Hat 4.8.3-9) (GCC) )
Docker 版本：
# docker version
Client:
Version: 1.12.1
API version: 1.24
Go version: go1.6.3
Git commit: 23cf638
Built:

Server:
Version: 1.12.1
API version: 1.24
Go version: go1.6.3
Git commit: 23cf638

OS/Arch: linux/amd64
设置群管理器：
>docker swarm init --advertise-addr 10.1.1.40:2377 --force-new-cluster
// on some retry attempts (after 'docker swarm leave --force') I ran:
>docker swarm init --advertise-addr 10.1.1.40:2377 --force-new-cluster
经理状态：
>docker node inspect self

在工作节点上（我有两个，但它们的行为相同）。
加入 Swarm：
>docker swarm join --token SWMTKN-1-4fjh7kncdpwjvxnxisamhldgenmmnqyvhnx9qdi8d4hkkfuacv-168gs9okd5ck0r4lokdgpef92 10.1.1.40:2377

Docker info 命令的输出：

根据下面的第一个答案进行编辑
所以我尝试使用 stop/start 周围的命令离开。我做到了：
# docker swarm leave --force
Node left the swarm.
# service docker stop
Redirecting to /bin/systemctl stop docker.service
#
# service docker start
Redirecting to /bin/systemctl start docker.service
# docker swarm init --advertise-addr 10.1.1.40:2377
Swarm initialized: current node (0e0y2k2hngnwyeg86ilzbrjmu) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join \
--token SWMTKN-1-2ggj60tnbppgjlg63a58oe5pqtv0vfrpj81hheawanf76x7cjc-7v48qak22wd03y3jyv903a9if \
10.1.1.40:2377
然后在我做的工人身上：
# docker swarm leave
Node left the swarm.
# service docker stop
Redirecting to /bin/systemctl stop docker.service
# service docker start
Redirecting to /bin/systemctl start docker.service
# docker swarm join \
> --token SWMTKN-1-2ggj60tnbppgjlg63a58oe5pqtv0vfrpj81hheawanf76x7cjc- 7v48qak22wd03y3jyv903a9if \
> 10.1.1.40:2377
Error response from daemon: Timeout was reached before node was joined. Attempt to join the cluster will continue in the background. Use "docker info" command to see the current swarm status of your node.
这显然是相同的行为......
更新
我已经尝试了@Miad Abrin 列出的所有步骤。我仍然得到相同的行为。我猜原因与我看到的 CERTS 错误有关：
# journalctl -xe

有谁知道这个问题的原因以及如何纠正？
【问题讨论】：
-
工人能ping通经理的ip吗？
-
尝试简单的“docker swarm init --advertise-addr 10.1.1.40”，不带尾随端口号。最重要的是，工作节点能否看到该 IP 地址？没有防火墙或其他可能阻塞路径的东西
-
我认为您的令牌不正确。检查
uacv-之后的空格 -
@MarkO'Connor 没有防火墙/代理或任何类似的东西。工作人员的“nmap”程序“看到”管理器主机上的开放端口
-
@Alkaline 就是这么剪切和粘贴。我试图纠正，但我执行的实际命令是直接从一个窗口复制并粘贴到另一个窗口。
