一、实验环境：

还原新系统后，创建3台docker，开机。

二、修改三台节点的host文件、修改三台节点名称：

Node1主节点，node2\node3工作节点

node01.benet.com

node02.benet.com

node03.benet.com

Vim /etc/hosts
192.168.7.10 node01.benet.com
192.168.7.11 node02.benet.com
192.168.7.12 node03.benet.com

 “live-restore”: false,

[root@node01 ~]# systemctl restart docker 重启docker

三、初始化swarm集群、工作节点加入集群的命令

[root@node01 ~]# docker swarm init			初始化swarm集群
Swarm initialized: current node (0qre8ffdk6pkthiglkpkrqagt) is now a manager.

To add a worker to this swarm, run the following command:

    docker swarm join --token SWMTKN-1-4hxebsjeyisyajtqm1ow8pp9p5rhlv9zs1paq32y78zmacp86                                                                                                              m-5ffv7jf0ns21vzfzmsly4lwg1 192.168.7.10:2377

To add a manager to this swarm, run 'docker swarm join-token manager' and follow the ins                                                                                                              tructions.										工作节点加入集群的命令
[root@node01 ~]#

四、将node02、node03节点加入到集群中

[root@node02 ~]# docker swarm join --token SWMTKN-1-4hxebsjeyisyajtqm1ow8pp9p5rhlv9zs1paq32y78zmacp86m-5ffv7jf0ns21vzfzmsly4lwg1 192.168.7.10:2377                                                                                This node joined a swarm as a worker.				将node2节点加入到集群中
[root@node02 ~]#
[root@node03 ~]# docker swarm join --token SWMTKN-1-4hxebsjeyisyajtqm1ow8pp9p5rhlv9zs1paq32y78zmacp86m-5ffv7jf0ns21vzfzmsly4lwg1 192.168.7.10:2377
This node joined a swarm as a worker.			将node3节点加入到集群中
[root@node03 ~]#

五、在主节点node01上查看集群节点信息

[root@node01 ~]# docker node ls				查看集群节点信息
ID                            HOSTNAME           STATUS    AVAILABILITY   MANAGER STATUS   ENGINE VERSION
0qre8ffdk6pkthiglkpkrqagt *   node01.benet.com   Ready     Active         Leader           28.2.2
4c8s73esc17uq7ftieytj8c6f     node02.benet.com   Ready     Active                          28.2.2
ofqnmn4zfx5b9dmvbh99qvaj4     node03.benet.com   Ready     Active                          28.2.2
[root@node01 ~]#
[root@node01 ~]# docker node ls				查看集群节点信息
ID                            HOSTNAME           STATUS    AVAILABILITY   MANAGER STATUS   ENGINE VERSION
0qre8ffdk6pkthiglkpkrqagt *   node01.benet.com   Ready     Active         Leader           28.2.2
4c8s73esc17uq7ftieytj8c6f     node02.benet.com   Ready     Active                          28.2.2
ofqnmn4zfx5b9dmvbh99qvaj4     node03.benet.com   Ready     Active                          28.2.2
[root@node01 ~]#

六、三台机器做时间同步

[root@node01 ~]# vim Dockerfile				创建dockerfile文件
[root@node01 ~]#
FROM rockylinux:9.2					使用rocky9.2的镜像
MAINTAINER serverworld <admin@srv.world>		作者信息
RUN yum -y install httpd					执行命令安装阿帕奇
RUN echo "node01.benet.com" > /var/www/html/index.html	执行命令安装阿帕奇的测试页面
EXPOSE 80							显示80端口
CMD ["-D", "FOREGROUND"]				该容器启动时在后台运行
ENTRYPOINT ["/usr/sbin/httpd"]			配置容器 启动阿帕奇
[root@node02 ~]# vim Dockerfile				创建dockerfile文件
FROM rockylinux:9.2					使用rocky9.2的镜像
MAINTAINER serverworld <admin@srv.world>	作者信息
RUN yum -y install httpd					执行命令安装阿帕奇
RUN echo "node02.benet.com" > /var/www/html/index.html	执行命令安装阿帕奇的测试页面
EXPOSE 80							显示80端口
CMD ["-D", "FOREGROUND"]				该容器启动时在后台运行
ENTRYPOINT ["/usr/sbin/httpd"]			配置容器 启动阿帕奇
[root@node03 ~]# vim Dockerfile				创建dockerfile文件
FROM rockylinux:9.2					使用rocky9.2的镜像
MAINTAINER serverworld <admin@srv.world>	作者信息
RUN yum -y install httpd				执行命令安装阿帕奇
RUN echo "node03.benet.com" > /var/www/html/index.html	执行命令安装阿帕奇的测试页面
EXPOSE 80						显示80端口
CMD ["-D", "FOREGROUND"]			该容器启动时在后台运行
ENTRYPOINT ["/usr/sbin/httpd"]		配置容器 启动阿帕奇

七、查看三台机器上是否有web_server 镜像、查看正在运行的容器

[root@node01 ~]# docker images					查看docker镜像

八、主节点node01 docker服务创建swarm集群

[root@node01 ~]# docker service create --name swarm_cluster --replicas=2 -p 80:80 web_server:latest  docker服务创建swarm集群
--replicas=2 副本数2 	并建立端口映射，宿主机的80映射到容器的80
[root@node01 ~]# docker service ls				  查看docker服务
ID             NAME            MODE         REPLICAS   IMAGE               PORTS
rd3od6qm3a07   swarm_cluster   replicated   2/2        web_server:latest   *:80->80/tcp

九、测试访问node1管理节点，是否轮询

只有两个节点node1,node3

十、扩展集群：将swarm集群扩展为3台

[root@node01 ~]# docker service scale swarm_cluster=3		将swarm集群扩展为3台
swarm_cluster scaled to 3
overall progress: 2 out of 3 tasks
1/3: running   [==================================================>]
2/3: running   [==================================================>]
3/3: preparing [=================================>                 ]

[root@node01 ~]# curl 192.168.7.10		测试 访问主节点IP
node02.benet.com
[root@node01 ~]# curl 192.168.7.10							轮询（采用）
node03.benet.com
[root@node01 ~]# curl 192.168.7.10
node01.benet.com

十一、测试集群里三台机器是否添加上并且轮询

实验二、如果还有额外节点加入集群的配置

一、实验环境：

再安装一台7.13命名为node04节点4

二、配置思路：

1、修改计算机名

2、修改所有节点的host文件

3、进行时间同步

4、在要加入集群节点的主机上，安装docker；（如：节点04上安装docker，并拍摄快照名为：docker;）

5、在新结点上创建docker文件，根据docker文件，创建web_server的镜像

6、将web_server镜像，在后台生成容器

三、修改计算机名

[root@Server13 ~]# hostnamectl set-hostname node04.benet.com
[root@Server13 ~]# exit
logout

四、安装docker，并拍摄快照名为：docker;

[root@Server13 ~]#yum install -y yum-utils device-mapper-persistent-data lvm2
Rocky Linux 9 - BaseOS                                                           507 kB/s | 2.5 MB     00:04

Dependencies resolved.
[root@Server13 ~]# systemctl enable --now docker
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.servi                               ce.
[root@Server13 ~]# vim /etc/docker/daemon.json		编辑docker进程的配置文件
{
    "registry-mirrors":[								表示dockers不起用实时恢复功能

        "https://mirror.baidubce.com",				守护进程重启时，所有运行的容器会被强制终止
        "https://9cpn8tt6.mirror.aliyuncs.com",

        "https://reg-mirror.qiniu.com",
        "https://registry.docker-cn.com"
    ]
}
[root@Server13 ~]# systemctl restart docker		重启docker
[root@Server13 ~]# shutdown -h now			初始化swarm集群

五、修改所有节点的host文件

[root@node01 ~]# vim /etc/hosts

[root@node02 ~]# vim /etc/hosts

[root@node03 ~]# vim /etc/hosts

[root@node04 ~]# vim /etc/hosts
192.168.7.10 node01.benet.com
192.168.7.11 node02.benet.com
192.168.7.12 node03.benet.com
192.168.7.13 node04.benet.com
[root@node01 ~]# docker swarm join-token manager		查看工作节点加入swarm集群的命令
To add a manager to this swarm, run the following command:

    docker swarm join --token SWMTKN-1-4hxebsjeyisyajtqm1ow8pp9p5rhlv9zs1paq32y78zmacp86m-72azhfad1z3n2rruvcj9s4ng3 192.168.7.10:2377     
This node joined a swarm as a manager.	将新节点加入到集群中
[root@node01 ~]#

六、node01、node02、node03、node04进行时间同步

#pool 2.rocky.pool.ntp.org iburst
pool ntp.aliyun.com iburst
[root@node01 ~]# systemctl enable --now chronyd

七、node1主节点将Docker文件给node04节点

[root@node01 ~]# scp Dockerfile 192.168.7.13:/root 复制Docker文件给node04节点

[root@node01 ~]# ls

anaconda-ks.cfg  Dockerfile

[root@node01 ~]# scp Dockerfile 192.168.7.13:/root

The authenticity of host ‘192.168.7.13 (192.168.7.13)’

ED25519 key fingerprint is SHA256:H7LflkvVNKIcCNphIsXrJ

This key is not known by any other names

Are you sure you want to continue connecting (yes/no/[f

Warning: Permanently added ‘192.168.7.13’ (ED25519) to

[root@node01 ~]#

八、在node04上编辑Dockerfile文件

[root@node04 ~]# vim Dockerfile
[root@node04 ~]#
FROM rockylinux:9.2
MAINTAINER serverworld <admin@srv.world>
RUN yum -y install httpd
RUN echo "node04.benet.com" > /var/www/html/index.html
EXPOSE 80
CMD ["-D", "FOREGROUND"]
ENTRYPOINT ["/usr/sbin/httpd"]

九、docker使用dockerfile文件创建web_server的镜像

[root@node04 ~]# docker build -t web_server:latest .		docker使用dockerfile文件创建web_server的镜像

十、删除节点和集群

[root@node01 ~]# docker node update --availability drain i21ublrvu993qpj8ji2ryuc97		将该节点停用
i21ublrvu993qpj8ji2ryuc97
[root@node01 ~]# docker swarm leave		离开节点
[root@node01 ~]# 

[root@node01 ~]# docker node rm 6whtoqrhkzv3ax4xy9ab20gmy   删除 node节点（在 master 上操作）
添加删除节点
[root@node01 ~]# docker swarm init		初始化swarm集群
Swarm initialized: current node (bvp2xk3ju7wh9bff5kar63rrp) is now a manager.

To add a worker to this swarm, run the following command:

    docker swarm join --token SWMTKN-1-247tqn51drak1zu683haeunra0mqbgidg1xad0l4sjqszbmao7-bda3i3e1ivl1awsbxh3xbfp9k 192.168.7.10:2377

To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
