前期准备 (需要安装git、jdk1.8，在此略过)

1、安装Docker CE

删除老版本,如果有或者不确定的话；
sudo yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-engine
使用repository安装
先设置
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager
–add-repo
https://download.docker.com/linux/centos/docker-ce.repo
安装DOCKER CE
sudo yum install docker-ce
启动
systemctl start docker
测试，如果需要的话
sudo docker run hello-world

配置监听Docker守护程序 监听TCP 2375
vi /lib/systemd/system/docker.service
增加加黑部分
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

重启服务
sudo systemctl daemon-reload
sudo systemctl restart docker
测试一下成功与否
curl http://localhost:2375/version
{“Platform”:{“Name”:""},“Components”:[{“Name”:“Engine”,“Version”:“18.06.1-ce”,“Details”:{“ApiVersion”:“1.38”,“Arch”:“amd64”,“BuildTime”:“2018-08-21T17:25:29.000000000+00:00”,“Experimental”:“false”,“GitCommit”:“e68fc7a”,“GoVersion”:“go1.10.3”,“KernelVersion”:“3.10.0-123.el7.x86_64”,“MinAPIVersion”:“1.12”,“Os”:“linux”}}],“Version”:“18.06.1-ce”,“ApiVersion”:“1.38”,“MinAPIVersion”:“1.12”,“GitCommit”:“e68fc7a”,“GoVersion”:“go1.10.3”,“Os”:“linux”,“Arch”:“amd64”,“KernelVersion”:“3.10.0-123.el7.x86_64”,“BuildTime”:“2018-08-21T17:25:29.000000000+00:00”}

2、安装Docker Compose

下载
sudo curl -L “https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname-s)-$(uname -m)” -o /usr/local/bin/docker-compose
修改权限
sudo chmod +x /usr/local/bin/docker-compose
测试安装成功否
docker-compose --version
docker-compose version 1.22.0, build f46880fe

3、启用Swarm mode

docker swarm init

4、构建

安装gradle
cd /usr/local/
wget https://services.gradle.org/distributions/gradle-4.10.2-bin.zip
unzip gradle-4.10.2-bin.zip
vi /etc/profile
将如下代码追加到 profile 文件末尾：

GRADLE_HOME=/usr/local/gradle-4.10.2
export PATH=$GRADL{E}_{H}OME/bin:${PATH}

重载/etc/profile这个文件
source /etc/profile
测试
gradle -version
生成gradlew
cd /usr/local/gradle-4.10.2
gradle wrapper
ln -s gradlew ./bin/gradlew

下载sitewhere
git clone https://github.com/sitewhere/sitewhere.git
cd sitewhere
git checkout --force sitewhere-2.0.rc2
执行Gradle构建脚本前先编辑gradle.properties，根据自己设置修改
dockerProtocol=tcp
dockerHostname=localhost (在本机所以不用ip或域名)
dockerPort=2375
dockerRepository=docker.io
registryUrl=https://index.docker.io/v1/
registryUsername=用户名
registryPassword=密码
registryEmail=邮箱

开始构建镜像
gradlew clean dockerImage
如果遇到Could not find tools.jar. Please check that /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.171-8.b10.el7_5.x86_64/jre contains a valid JDK installation

找下看有没
find / -name tools.jar
好吧，可能是阉割过的卸了重新安装
yum -y remove java-1.8.0-openjdk*
yum -y install java-1.8.0-openjdk*

没问题的话完工
docker images
应该可以看到构建镜像清单

5、部署

下载
git clone https://github.com/sitewhere/sitewhere-recipes.git
先构建启动基础服务镜像
cd sitewhere-recipes/docker-compose/infrastructure_default
docker-compose up
再启用默认微服务
cd sitewhere-recipes/docker-compose/default
docker-compose up

全部做完没报错的话，下载sitewhere-admin-ui
输入用户名admin密码password ，IP地址然后登录
