docker swarm 集群及可视化界面的安装及配置

本文是swarm docker集群的实施文档 环境： centos 7 192.168.1.23 swarm-manager rethinkdb controller swarm-agent consul-c1 registrator 192.168.1.45 registrator swarm-agent consul-s3 192.168.1.65 registrator swarm-agent consul-s2 192.168.1.66 registrator swarm-agent consul-s2 192.168.1.70 registrator consul-c2 consul-template (nginx、haproxy) 192.168.1.71 registrator consul-c2 consul-template (nginx、haproxy) docker-engine 1.12.4 一、安装docker-engine 1.12.4 1、先检查是否安装旧版本docker rpm-qa|grepdocker 如果有先卸载 yumremovedocker* 2.编辑docker.repo文件，写入如下内容 cat>>/etc/yum.repos.d/docker-main.repo<<EOF name=DockermainRepository baseurl=https://yum.dockerproject.org/repo/main/centos/7 enabled=1 gpgcheck=1 gpgkey= EOF 3.安装docker yum-yinstalldocker-engine 4.关闭防火墙和selinux systemctlstopfirewalld.service systemctldisablefirewalld.service 关闭selinux sed-i's/SELINUX=.*/SELINUX=disabled/g'/etc/selinux/config 重启 5.增加tcp监听端口 修改/lib/systemd/system/docker.service sed-i's/ExecStart=.*/ExecStart=\/usr\/bin\/dockerd-Hunix\:\/\/\/var\/run\/docker.sock-D-Htcp\:\/\/0.0.0.0\:2375/g'/lib/systemd/system/docker.service 6.重启docker systemctlenabledocker.service systemctlrestartdocker ps-ef|grepdocker 能看到docker启动及2375端口 7、安装pip及docker api yum-yinstallepel-release yum-yinstallpython-pip pipinstalldocker-pydocker-compose 二、配置consul cluster 1、创建consul 用户及组 groupadd-g1000consul useradd-u100-g1000-s/sbin/nologinconsul 2、创建consul 数据存储文件夹 mkdir-p/opt/consul/{data,conf} chown-Rconsul:/opt/consul 3、拉取consul镜像 dockerpullprogrium/consul 提示:目录没有官方出consul镜像，以上consul镜像是星数最高的，也是consul官方推荐的第三方dockerp_w_picpath 4、启动consul server 192.168.1.66 dockerrun-d\ -p8300:8300\ -p8301:8301\ -p8301:8301/udp\ -p8302:8302\ -p8302:8302/udp\ -p8400:8400\

dockerrun-d\ -p8300:8300\ -p8301:8301\ -p8301:8301/udp\ -p8302:8302\ -p8302:8302/udp\ -p8400:8400\ -p8500:8500\ -p8600:53\ -p8600:53/udp\ -v/opt/consul/data:/data\ -hconsul-s3\ --restart=always\ --name=consul-s3\ progrium/consul\ -server\ -ui-dir=/ui\ -client0.0.0.0\ -advertise192.168.1.45-join192.168.1.66 7、启动consul Client192.168.1.23 dockerrun-d-hconsul-c1\ -p8300:8300\ -p8301:8301\

progrium/consul-advertise192.168.1.23-join192.168.1.66 8、启动consulClient192.168.1.70 dockerrun-d-hconsul-c2\ -p8300:8300\ -p8301:8301\ -p8301:8301/udp\ -p8302:8302\ -p8302:8302/udp\ -p8400:8400\ -p8500:8500\ -p8600:53\ -p8600:53/udp\ -v/opt/consul/data:/data\ --restart=always\ --name=consul-c2\ progrium/consul-advertise192.168.1.70-join192.168.1.66 9、启动consulClient192.168.1.71 dockerrun-d-hconsul-c3\ -p8300:8300\ -p8301:8301\ -p8301:8301/udp\ -p8302:8302\ -p8302:8302/udp\ -p8400:8400\ -p8500:8500\ -p8600:53\ -p8600:53/udp\ -v/opt/consul/data:/data\ --restart=always\ --name=consul-c3\ progrium/consul-advertise192.168.1.71-join192.168.1.66 10、关闭consul-s1并删除容器 dockerrm-fconsul-s1 重新启动一个新容器 dockerrun-d\ -p8300:8300\ -p8301:8301\ -p8301:8301/udp\ -p8302:8302\

9、设置开机启动 chmod+xnginx_ctmpl chkconfignginx_ctmplon servicenginx_ctmplstart 七、测试是否自动发现 dockerrun-ti-d-p:80eboraas/apache-php dockerrun-d-ti-p:80nginx 1、打开http://192.168.1.66:8500/ui/#/dc1/services 2、http://192.168.1.23:8080/#/containers 查看shipyard 管理平台 账号admin密码shipyard 3、haproxy http://192.168.1.70:8888/admin?stats http://192.168.1.71:8888/admin?stats 账号：admin 密码admin 最后：注意事项：consul registrator 是基于端口发现的不映射端口是发现不了的 consul 服务挂了整个宿主机运行应用将不可见。registrator 是基于镜像名加端口服务 镜像名称为nginx 多端口暴露 对外发现的服务名称nginx-80 单个端口暴露就是镜像名称为服务名 像集群添加宿主机 consul registrator swarm-agent registrator 链接consul 端口请使用宿主机的consul 端口 使用其它机器端口如果其它机器挂了这台宿主机的应用不可被发现
