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|grep docker 如果有先卸载 yum remove docker*
2.编辑docker.repo文件，写入如下内容
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
yum -y install docker-engine
4.关闭防火墙和selinux
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
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
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
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
groupadd -g 1000 consul useradd -u 100 -g 1000 -s /sbin/nologin consul
2、创建consul 数据存储文件夹
mkdir -p /opt/consul/{data,conf}
chown -R consul: /opt/consul3、拉取consul镜像
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
docker run -d -p 8300:8300 -p 8301:8301 -p 8301:8301/udp -p 8302:8302 -p 8302:8302/udp -p 8400:8400 -p 8500:8500 -p 8600:53 -p 8600:53/udp -v /opt/consul/data:/data -h consul-s1 --restart=always --name=consul-s1 progrium/consul -server -bootstrap-expect=1 -ui-dir=/ui -client 0.0.0.0 -advertise 192.168.1.66
5、启动consul server 192.168.1.65
docker run -d -p 8300:8300 -p 8301:8301 -p 8301:8301/udp -p 8302:8302 -p 8302:8302/udp -p 8400:8400 -p 8500:8500 -p 8600:53 -p 8600:53/udp -v /opt/consul/data:/data -h consul-s2 --restart=always --name=consul-s2 progrium/consul -server -ui-dir=/ui -client 0.0.0.0 -advertise 192.168.1.65 -join 192.168.1.66
6、启动consul server 192.168.1.45
docker run -d -p 8300:8300 -p 8301:8301 -p 8301:8301/udp -p 8302:8302 -p 8302:8302/udp -p 8400:8400 -p 8500:8500 -p 8600:53 -p 8600:53/udp -v /opt/consul/data:/data -h consul-s3 --restart=always --name=consul-s3 progrium/consul -server -ui-dir=/ui -client 0.0.0.0 -advertise 192.168.1.45 -join 192.168.1.66
7、启动consul Client 192.168.1.23
docker run -d -h consul-c1 -p 8300:8300 -p 8301:8301 -p 8301:8301/udp -p 8302:8302 -p 8302:8302/udp -p 8400:8400 -p 8500:8500 -p 8600:53 -p 8600:53/udp -v /opt/consul/data:/data --restart=always --name=consul-c1 progrium/consul -advertise 192.168.1.23 -join 192.168.1.66
8、启动consul Client 192.168.1.70
docker run -d -h consul-c2 -p 8300:8300 -p 8301:8301 -p 8301:8301/udp -p 8302:8302 -p 8302:8302/udp -p 8400:8400 -p 8500:8500 -p 8600:53 -p 8600:53/udp -v /opt/consul/data:/data --restart=always --name=consul-c2 progrium/consul -advertise 192.168.1.70 -join 192.168.1.66
9、启动consul Client 192.168.1.71
docker run -d -h consul-c3 -p 8300:8300 -p 8301:8301 -p 8301:8301/udp -p 8302:8302 -p 8302:8302/udp -p 8400:8400 -p 8500:8500 -p 8600:53 -p 8600:53/udp -v /opt/consul/data:/data --restart=always --name=consul-c3 progrium/consul -advertise 192.168.1.71 -join 192.168.1.66
10、关闭consul-s1并删除容器
docker rm -rf consul-s1 重新启动一个新容器 docker run -d -p 8300:8300 -p 8301:8301 -p 8301:8301/udp -p 8302:8302 -p 8302:8302/udp -p 8400:8400 -p 8500:8500 -p 8600:53 -p 8600:53/udp -v /opt/consul/data:/data -h consul-s2 --restart=always --name=consul-s2 progrium/consul -server -ui-dir=/ui -client 0.0.0.0 -advertise 192.168.1.66 -join 192.168.1.65 进入容器运行 consul info 查询是否实现自动选举Leader
三、registrator状态获取
依次启动 docker run -d --restart=always --name=registrator --net=host -v /var/run/docker.sock:/tmp/docker.sock gliderlabs/registrator -ip 192.168.1.66 consul://192.168.1.66:8500 docker run -d --restart=always --name=registrator --net=host -v /var/run/docker.sock:/tmp/docker.sock gliderlabs/registrator -ip 192.168.1.65 consul://192.168.1.65:8500 docker run -d --restart=always --name=registrator --net=host -v /var/run/docker.sock:/tmp/docker.sock gliderlabs/registrator -ip 192.168.1.45 consul://192.168.1.45:8500 docker run -d --restart=always --name=registrator --net=host -v /var/run/docker.sock:/tmp/docker.sock gliderlabs/registrator -ip 192.168.1.23 consul://192.168.1.23:8500 docker run -d --restart=always --name=registrator --net=host -v /var/run/docker.sock:/tmp/docker.sock gliderlabs/registrator -ip 192.168.1.70 consul://192.168.1.70:8500 docker run -d --restart=always --name=registrator --net=host -v /var/run/docker.sock:/tmp/docker.sock gliderlabs/registrator -ip 192.168.1.71 consul://192.168.1.71:8500
四、安装 Shipyard+Swarm

exit 1
;;
esac
exit 04、启动 haproxy 并加入开机启动
chmod +x haproxy chkconfig haproxy on service haproxy start
5、安装nginx 并支支持数字证书

添加nginx默认web配置文件
/etc/nginx/conf.d/default.conf
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root /usr/local/nginx/html;
index index.php index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

include fastcgi_params;
}
location ~* ^.+\.(jpg|jpeg|gif|png|bmp)$ {
access_log off;
root opencart;
expires 30d;
break;
}
}7、创建nginx 启动脚本 /etc/init.d/nginx
# chkconfig: 2345 10 90

proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_headers_hash_max_size 51200;
proxy_headers_hash_bucket_size 6400;
proxy_pass http://nginx/;
}
}8、配置consul-template nginx启动脚本 /etc/init.d/nginx_ctmpl
#!/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
esac9、设置开机启动
chmod +x nginx_ctmpl chkconfig nginx_ctmpl on service nginx_ctmpl start
七、测试是否自动发现
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 映射端口80 对外发现的服务名称nginx-80
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
