摘要:
1、部署
系统时centos7上
关闭防火墙 systemctl stop firewalld.service
关闭selinux vi /etc/selinux/comfig
192.168.10.140 swarm manager
192.168.10.141 swarm node
192.168.10.142 swarm mode
2、分别在manager节点和node节点上安装docker
安装方式参照我的另一篇文章docker安装http://galengao.github.io/docker/2016/06/03/mydocker-use.html
yum update tee /etc/yum.repos.d/docker.repo<<EOF [dockerrepo] name=Docker Repository baseurl=https://yum.dockerproject.org/repo/main/centos/7/ enabled=1 gpgcheck=1 gpgkey=https://yum.dockerproject.org/gpg EOF yum install docker-engine
3、分别在manager节点和node节点上配置docker
vi /lib/systemd/system/docker.service # 修改ExecStart项为如下： ExecStart=/usr/bin/docker daemon -H 0.0.0.0:2375 -H unix:///var/run/docker.sock # 重新载入配置，使修改生效。 systemctl daemon-reload # 重启docker。 systemctl restart docker
4、在manager节点和node节点上push swarm镜像
[root@swarm1 ~]# docker pull swarm Using default tag: latest latest: Pulling from library/swarm 1e61bbec5d24: Pull complete 8c7b2f6b74da: Pull complete 245a8db4f1e1: Pull complete Digest: sha256:661f2e4c9470e7f6238cebf603bcf5700c8b948894ac9e35f2cf6f63dcda723a Status: Downloaded newer image for swarm:latest
5、创建集群token，获取全球唯一的 token，作为集群唯一标识
# 在任何节点都可以，但是要记住该值，以后要用到 [root@swarm1 ~]# docker run --rm swarm create eca9b4ab85feb53f8a9676c72dd01b1a
6、加入集群
# 在manager也就是节点node1 [root@swarm1 ~]# docker run -d swarm join -addr=192.168.10.140:2375 token://eca9b4ab85feb53f8a9676c72dd01b1a 109da11914295c588c6afe5f83ab731bd0d0012897c39c311de89534e2f5bc13 # node2上 [root@swarm1 ~]# docker run -d swarm join -addr=192.168.10.141:2375 token://eca9b4ab85feb53f8a9676c72dd01b1a 1da02eb6a00a8860eefe965a0aded446aebff8b502962c717dd3f494b546841a # node3上 [root@swarm1 ~]# docker run -d swarm join -addr=192.168.10.142:2375 token://eca9b4ab85feb53f8a9676c72dd01b1a b5483c91bff0ad21e19700af51990d631e991f9d67188c7419f147652d494972
7、启动管理机
# 在管理机上执行: [root@swarm1 ~]# docker run -d -p 2376:2375 swarm manage token://eca9b4ab85feb53f8a9676c72dd01b1a 3073a3dd59a5782f706d6481cfd1a36e8090f21764dfec2532899450bd719456
8、查看节点信息
# 本机上查看节点信息 [root@swarm1 ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 1da02eb6a00a swarm "/swarm join -addr=19" 27 minutes ago Up 27 minutes 2375/tcp sick_bose # 查看集群所有节点信息，在任何一台机器上执行 [root@swarm1 ~]# docker run --rm swarm list token://eca9b4ab85feb53f8a9676c72dd01b1a 192.168.10.142:2375 192.168.10.141:2375 192.168.10.140:2375 # 查看集群详细信息。在任何一台机器上执行: # 该IP地址是manager的地址 [root@swarm1 ~]# docker -H 192.168.10.140:2376 info Containers: 0 Running: 0 Paused: 0 Stopped: 0 Images: 0 Server Version: swarm/1.2.3 Role: primary Strategy: spread Filters: health, port, containerslots, dependency, affinity, constraint Nodes: 3 (unknown): 192.168.10.142:2375 └ ID: └ Status: Pending └ Containers: 0 └ Reserved CPUs: 0 / 0 └ Reserved Memory: 0 B / 0 B └ Labels: └ UpdatedAt: 2016-07-28T07:54:39Z └ ServerVersion: (unknown): 192.168.10.141:2375 └ ID: └ Status: Pending └ Containers: 0 └ Reserved CPUs: 0 / 0 └ Reserved Memory: 0 B / 0 B └ Labels: └ UpdatedAt: 2016-07-28T07:54:39Z └ ServerVersion: (unknown): 192.168.10.140:2375 └ ID: └ Status: Pending └ Containers: 0 └ Reserved CPUs: 0 / 0 └ Reserved Memory: 0 B / 0 B └ Labels: └ UpdatedAt: 2016-07-28T07:54:39Z └ ServerVersion: Plugins: Volume: Network: Kernel Version: 3.10.0-229.el7.x86_64 Operating System: linux Architecture: amd64 CPUs: 0 Total Memory: 0 B Name: 3073a3dd59a5 Docker Root Dir: Debug mode (client): false Debug mode (server): false WARNING: No kernel memory limit support
