Instructions

将以下条目添加到 SCG 虚拟机上的文件 /etc/init.d/after.local ，然后重新启动 SCG 虚拟机。
这将在每次重新启动后将 SCG 基础架构 IP 地址添加到 esrsde-app 容器内的主机文件。

步骤：

  1. cd /etc/init.d
  2. vi after.local
  3. 按“i”（插入模式）
  4. 将以下部分复制并粘贴到 vi 编辑器中
  5. 按 ESC 键，然后键入“：wq！”（冒号、WQ、感叹号，不带引号）
  6. 键入“reboot”，然后按 回车键

Additional Information

此过程不适用于 SCG 5.28 新安装。  可以遵循该过程，但在每次引导后执行 after.local 之前，需要升级到 5.30+。  可以手动运行一次命令，以便能够完成升级过程。
