将Amazon Linux 2
保存为AMI (Amazon Machine Images)
后,恢复成EC2 Instance
(实例)后,VNC
服务以及Chrome
浏览器无法启动,进行了解决。
问题及解决
如果要将一个EC2 Instance
(实例)从一个VPC
(Virtual Private Cloud)中迁移到另一个 VPC
中,需要将EC2 Instance
(实例)保存为AMI (Amazon Machine Images)
,再从另一个 VPC
恢复这个实例。进行了此操作后,恢复后的大部分功能直接使用,但是碰到了VNC
服务以及Chrome
浏览器无法启动的问题。
VNC服务无法启动
报以下错误:
[ec2-user@ip-100-92-28-119 ~]$ sudo systemctl status vncserver@:1

解决办法,删除旧有的导致服务锁定的一些文件,例如使用以下办法解决了问题:
[ec2-user@ip-100-92-28-119 ~]$ sudo rm -rf /tmp/.X11-unix/X2
[ec2-user@ip-100-92-28-119 ~]$ sudo systemctl start vncserver@:1

Chrome
浏览器无法启动
由于旧有的AMI (Amazon Machine Images)
里面遗留的用户信息,Chrome
浏览器无法启动,报以下错误:

进行以下操作删除旧有用户信息也就是Singleton*
相关文件,可以解决问题:
[ec2-user@ip-100-92-28-119 chromium]$ pwd
/home/ec2-user/.config/chromium

可以正常启动chromium-browser
