前置检查
-
以root用户进入上传软件包节点appctl.sh文件所在目录。
cd /data/docker-service
-
执行以下命令，进行安装前检查。未配置节点互信的情况下，请根据提示输入root密码。
如果是SUSE操作系统，在执行前置检查的命令前，需要执行以下命令替换前置检查脚本。
\cp -af /data/docker-service**/action/mainAction/precheck.sh.suse** /data/docker-service**/action/mainAction/precheck.sh**
sh appctl.sh precheck
回显如下，说明前置检查通过。

ERROR信息处理可参考前置检查报错处理。
