【Linux】Rocky 9.0 Podman服务无法正常启动

news/2024/4/29 16:56:13/文章来源:https://blog.csdn.net/cnskylee/article/details/126623492

Rocky Linux 9.0发布后，我在本地虚拟机对该版本进行了安装和测试，发现Podman服务在某些情况下，无法正常启动。

当/etc/selinux/config配置中，SELINUX=enforcing为默认配置的时候，启动Podman服务，会出现下面的报错。

[root@rocky-9 ~]# systemctl status podman.service

发现此问题后，我第一时间上报问题到社区论坛

从官方技术人员给的回复来看，是selinux导致了上面问题的出现，并且说这个问题可以通过更新container-selinux到2.179版本来解决。

但是，时隔一个多月后，我再次测试，并将container-selinux升级到了2.189版本，此问题仍未能解决。

[root@rocky-9 ~]# rpm -qa container-selinux

目前，此问题只能通过将selinux设置为SELINUX=disabled，并重启系统的方式，才能暂时解决。

这时，在Rocky Linux 9的可视化管理后台中，就可以正常使用Podman来下载镜像和运行容器实例了。
