空白屏幕在Linux上安装Db2开发人员社区版

Question

RHEL 7.3 64位。安装程序进入带有进度条的安装屏幕，我看到的最后一件事是它正在下载一些Docker文件。当我回来检查时，我看到的只是一个空白屏幕：

帮助菜单说安装程序是版本1.1.2（7/21/2017）。安装程序以root身份运行，这是控制台：

# ./ibm-db2-developer_community_edition-1.1.2-x86_64.AppImage 
installed: X-AppImage-BuildId=0d7243c0-6e2f-11a7-104f-052bf6805623 image: X-AppImage-BuildId=0d7243c0-6e2f-11a7-104f-052bf6805623
in the prod if statement

它已经暂停了一段时间，并且该过程没有使用任何CPU。

编辑：我重新运行了安装程序，并且这次更密切地关注了它。现在，它停留在18％：

大约每5秒钟，ibm-db2-develop会弹出相当高的CPU几秒钟。我用strace -f -tt -o outputfile.txt -p ${PID}附加了strace，我在read syscalls中注意到了一些HTTP 404和429：

21477 13:45:17.682583 read(42, "HTTP/1.1 200 OK\r\nDate: Tue, 05 S"..., 65536) = 200
21477 13:45:19.700105 read(43, "HTTP/1.1 404 Not Found\r\nContent-"..., 65536) = 230
21477 13:45:19.700717 read(59, "HTTP/1.1 404 Not Found\r\nContent-"..., 65536) = 236
21477 13:45:19.731156 read(42, "HTTP/1.1 429 Too Many Requests\r\n"..., 65536) = 763

看起来大多数请求都是针对某种速度测试的，尽管有些似乎与Docker容器有关：

编辑：我使用-s的{​​{1}}参数转储更多响应，容器请求返回404：

strace

Answer 1

解决方法是禁用SELinux：

sudo setenforce Permissive

我已经确认并成功安装了产品：

$ docker ps
