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

1 2 3

rpm -qa|grep docker 如果有先卸载 yum remove docker*

2.编辑docker.repo文件，写入如下内容

1 2 3 4 5 6 7

cat >> /etc/yum.repos.d/docker-main.repo << EOF name=Docker main Repository baseurl=https://yum.dockerproject.org/repo/main/centos/7 enabled=1 gpgcheck=1 gpgkey= EOF

3.安装docker

1	yum -y install docker-engine

4.关闭防火墙和selinux

1 2 3 4 5

systemctl stop firewalld.service systemctl disable firewalld.service 关闭selinux sed -i 's/SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config  重启

5.增加tcp监听端口

1 2	修改/lib/systemd/system/docker.service sed -i 's/ExecStart=.*/ExecStart=\/usr\/bin\/dockerd -H unix\:\/\/\/var\/run\/docker.sock -D -H tcp\:\/\/0.0.0.0\:2375/g' /lib/systemd/system/docker.service

6.重启docker

1 2 3 4

systemctl enable docker.service systemctl restart docker ps -ef|grep docker 能看到docker启动及2375端口

7、安装pip及docker api

1 2 3

yum -y install epel-release yum -y install python-pip pip install docker-py docker-compose

二、配置consul cluster

1、创建 consul 用户及组

1 2	groupadd -g 1000 consul useradd -u 100 -g 1000 -s /sbin/nologin consul

2、创建consul 数据存储文件夹

1 2	mkdir -p /opt/consul/{data,conf} chown -R consul: /opt/consul

3、拉取consul镜像

1 2	docker pull progrium/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docker image

4、启动consul server 192.168.1.66

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

8、设置nginx开机启动并启动nginx

1 2 3

chmod +x nginx  chkconfig nginx on service nginx start

六、安装consul-template 实现服务器自动发现

1、下载consul-template

https://releases.hashicorp.com/consul-template/0.16.0/consul-template_0.16.0_linux_amd64.zip

1 2 3 4

2、consul-template  haproxy配置

1 2 3 4 5 6 7 8 9

cat > /opt/consul/conf/haproxy_ctmpl.json << EOF consul = "127.0.0.1:8500"     template {   source = "/opt/haproxy/conf/haproxy.ctmpl"   destination = "/opt/haproxy/conf/haproxy.conf"   command = "/etc/init.d/haproxy reload" } EOF

5、设置开机启动，启动

1 2 3

chmod +x haproxy_ctmpl  chkconfig haproxy_ctmpl on service haproxy_ctmpl start

6、consul-template  nginx配置 /opt/consul/conf/nginx_ctmpl.json

1 2 3 4 5 6 7 8 9

cat > /opt/consul/conf/nginx_ctmpl.json << EOF consul = "127.0.0.1:8500"     template {   source = "/etc/nginx/conf.d/nginx_web.ctmpl"   destination = "/etc/nginx/conf.d/nginx_web.conf"   command = "/usr/sbin/nginx  -s reload" } EOF

7、/etc/nginx/conf.d/nginx_web.ctmpl 配置

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72

8、配置consul-template  nginx启动脚本 /etc/init.d/nginx_ctmpl

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37

#!/bin/bash # chkconfig: 2345 10 90 # description: Start and Stop redis   PATH=/usr/local/bin:/sbin:/usr/bin:/bin EXEC=/usr/bin/consul-template CONF="/opt/consul/conf/nginx_ctmpl.json" case "$1" in         start)                  PID=$(ps -ef | grep -v grep  | grep "$EXEC -config $CONF" | awk '{print $2}')                if [ -n "$PID"   ]                    then                      echo "haproxy_ctmpl is running..."               else                 echo "Starting haproxy_ctmpl server..."                         $EXEC -config $CONF > /tmp/nginx_ctmpl.out 2>&1 &              fi              ;;        stop)             PID=$(ps -ef | grep -v grep  | grep "$EXEC -config $CONF" | awk '{print $2}')             if [  -n "$PID" ]                  then                         echo "Stopping..."                         kill -9 $PID                         sleep 2                else                echo "haproxy_ctmpl exists, process is not running."              fi              ;;        restart|force-reload)                 ${0} stop                 ${0} start                 ;; *)                echo "Usage: /etc/init.d/tmpl {start|stop|restart|force-reload}" >&2                 exit 1 esac

9、设置开机启动

1 2 3

chmod +x nginx_ctmpl  chkconfig nginx_ctmpl on service nginx_ctmpl start

七、测试是否自动发现

1 2	docker run -ti -d -p :80 eboraas/apache-php  docker run -d -ti -p :80 nginx

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
