centos 9 安装失败

[ck-Coding]

在centos 9 上安装似乎会出触发OOM保护机制，将进程连同sshd杀死，导致安装失败。

上方的这个错误，是因为脚本中，这一段代码的错误 utils/dependencies.sh#L83C9-L87 导致的，但是，它并没有任何影响，因为，我用 CentOS 9 看了下，它的 EPEL 库 默认是启用的。

至于你说的会触发OOM保护机制，这是你的系统内存不足的原因。

[ck-Coding]

你好，脚本我是在aws lightsail centos 9 stream上测试的，之前在同样内存(512M)的centos 7似乎没有出现这个问题，且多次重装机器都是这个错误（ssh连接断开，安装中断失败），检查了系统日志后发现出现了内存不足杀进程的信息。检查了下系统内存还有282MiB的空间:
free -h
total used free shared buff/cache available
Mem: 438Mi 111Mi 282Mi 11Mi 66Mi 327Mi
Swap: 0B 0B 0B

我刚在 Vultr 进行了安装测试，VPS配置： 1 vCPU/1 GB Memory 、 CentOS 9 Stream x64 它是可以安装成功的。至于，最低内存限制是多少，我没测试过，这个可能要你自己测试了。

之前在同样内存(512M)的centos 7似乎没有出现这个问题

至于你的这个问题，会不是，CentOS 9 Stream 比 CentOS 7 更占用内存？

在开启了服务器的swap分区后可以成功安装组件，但安装过程中又出现了shadowsocks 下载失败的错误：
