一、以docker方式部署RPA服务端

1. 拷贝资源文件

通过scp 或者其他方式把docker 目录和server 目录传输到部署服务器上的/root根目录下。
（docker和server目录，请联系阿里云RPA同学获取）

scp -r docker root@server_ip:/root
scp -r server root@server_ip:/root

docker资源文件：

├── docker│ ├── docker-ce # docker离线安装包及其依赖
│ │ ├── audit-2.8.4-4.el7.x86_64.rpm│ │ ├── audit-libs-2.8.4-4.el7.x86_64.rpm│ │ ├── audit-libs-python-2.8.4-4.el7.x86_64.rpm│ │ ├── checkpolicy-2.5-8.el7.x86_64.rpm│ │ ├── container-selinux-2.74-1.el7.noarch.rpm│ │ ├── docker-ce-18.03.1.ce-1.el7.centos.x86_64.rpm│ │ ├── libcgroup-0.41-20.el7.x86_64.rpm│ │ ├── libselinux-2.5-14.1.el7.x86_64.rpm│ │ ├── libselinux-python-2.5-14.1.el7.x86_64.rpm│ │ ├── libselinux-utils-2.5-14.1.el7.x86_64.rpm│ │ ├── libsemanage-2.5-14.el7.x86_64.rpm│ │ ├── libsemanage-python-2.5-14.el7.x86_64.rpm│ │ ├── libsepol-2.5-10.el7.x86_64.rpm│ │ ├── libtool-ltdl-2.4.2-22.el7_3.x86_64.rpm│ │ ├── pigz-2.3.4-1.el7.x86_64.rpm│ │ ├── policycoreutils-2.5-29.el7.x86_64.rpm│ │ ├── policycoreutils-python-2.5-29.el7.x86_64.rpm│ │ ├── python-IPy-0.75-6.el7.noarch.rpm│ │ ├── selinux-policy-3.13.1-229.el7_6.6.noarch.rpm│ │ ├── selinux-policy-targeted-3.13.1-229.el7_6.6.noarch.rpm│ │ └── setools-libs-3.3.8-4.el7.x86_64.rpm│ └── docker-compose└── server
├── cs-docker.tar # RPA服务端镜像文件
└── docker-compose.yml # docker启动脚本

默认docker是针对centos 7.4版本，如果安装的centos 是其他版本如7.3，在安装过程中缺少相应的依赖包，需要联网下载对应版本的docker-ce里面的离线安装包。

2. 安装和启动docker

进入docker-ce目录，执行

yum localinstall *.rpm # 如果提示选择选Y

安装完成后执行

systemctl start docker

3. 部署阿里云RPA

（1）将编排文件docker-compose拷贝到用户bin目录，并提权

sudo cp -f ~/docker/docker-compose /usr/bin/
sudo chmod +x /usr/bin/docker-compose

(2) 进入到server目录执行

cd ~/serversudo docker load -i cs-docker.tar

(3) 查看导入的docker镜像

[root@rpa ~]# docker images
REPOSITORY **TAG** **IMAGE** ID CREATED SIZE`
registry.cn-hangzhou.aliyuncs.com/codestore/rpa-mysql V3.3.11 b3cd3de42e96 2 weeks ago 372MB

registry.cn-hangzhou.aliyuncs.com/codestore/rpa-redis V3.3.11 3ecb7a463946 3 weeks ago 107MB

（4）修改docker-compose.yml文件。
先登陆登陆k8s的 master 节点，查看 mysql 和 redis 配置文件 values.yaml ，找到数据库的密码，然后将写到 docker-compose.yml 文件的对应位置

（5）启动docker镜像

sudo docker-compose -f docker-compose.yml up -d

二.拷贝k8s方式部署的RPA服务端数据

1、打包RPA服务端的所有数据

RPA服务端的所有数据都保存在 work 节点的 /rpadata/ 目录下，备份整个/rpadata/目录即可。

[root@linux ~]# tar -czvf ~/rpadata.tar.gz /rpadata/ # 备份数据到home目录下

2、将打包好的RPA服务端数据拷贝到新的服务器上

scp ~/rpadata.tar.gz root@server_ip:/root # 将数据拷贝到新的服务器root目录下

3、将备份的文件解压到/rpadata/目录下

[root@linux ~]# cd /[root@linux ~]# tar -xzvf ~/rpadata.tar.gz

三、启动阿里云RPA服务

（1）启动docker镜像

sudo docker-compose -f docker-compose.yml up -d

（2）设置docker-compose开机启动

vim /etc/rc.d/rc.****local**** # 编辑启动脚本，在末尾添加一行，加入下面的脚本systemctl start docker/usr/bin/docker-compose -f /root/server/docker-compose.yml up -d # 注意修改成自己的docker-compose.yml文件位置sudo chmod +x /etc/rc.d/rc.**local**

四、查看结果

在服务器上执行，需要把IP改成自己的服务器IP

[root@rpa ~]# curl -H "Host:rpa.aliyun.net" http://106.15.137.252/login # 注意把**ip**换成自己服务器的**IP**<!DOCTYPE html><html><head>
