现在RHEL8已经淘汰了，Docker不再是一个可行的选择，所以我试图让集群在Podman中运行，但是遇到了权限错误。无论出于何种原因，无论我尝试什么，我都会得到java.lang.IllegalStateException: Unable to access 'path.data' (/usr/share/elasticsearch/data)
目录设置
mkdir /var/elasticsearch-data
mkdir /var/elasticsearch-data/data01
mkdir /var/elasticsearch-data/data02
mkdir /var/elasticsearch-data/data03
mkdir /var/elasticsearch-data/data04
chmod -R g+rwx /var/elasticsearch-data
chgrp -R 0 /var/elasticsearch-data
我最终只是放弃了，并使用
chmod -R 777 /var/elasticsearch-data设置了目录，错误仍然存在。我尝试将目录所有权更改为非特权用户，并且尝试更改组。Podman撰写文件

还有其他人遇到吗？
最佳答案
这不是这个问题的真正答案，但是如果它可以帮助遇到此问题的其他人，这就是如何在RHEL-8上安装Docker。您必须强制安装容器的最新版本。我无法弄清楚Podman compose的权限出了什么问题。
