CentOS7 怎么安装这个内核模块 #10

Closed hzl000 closed 1 year ago

hzl000 commented 1 year ago

你好我的一台X86的服务器打算运行一个ReDroid实例，在docker启动了之后一直无法连上adb，看了issue应该就是缺少binder，ashmem。 我看了一下确实是没有这2个模块。看了文档都是以ubuntu做示例，由于我不太熟linux，翻查了好久也不知道该怎么安装这些内核模块。

try build your own kernel, check https://github.com/remote-android/redroid-doc/blob/master/deploy/centos.md

yes, actually i follow the centos.md to do, and then i successfully to launch the redroid in the docker. but adb didn't found the redroid, i saw a tips Binder driver could not be opened. Terminating. in logcat. that because my env doesn't have binder ashmem kernel modules.

now i found a way to install those modules that by dkms. i follow DKMS step of https://github.com/remote-android/redroid-modules/blob/master/README.md so sad i meet some error when i invoke dkms install redroid-ashmem/1 dkms install redroid-binder/1

i had upgrade kernel gcc my command line history following:

The modules here are out of tree porting, and may not work out of the box. It's created primary for some old kernels (pre 5.0) and public cloud (AWS, Aliyun etc.)

For CentOS, suggest to build your own custom kernel.
