在Linux上安裝Db2 Developer Community Edition的空白屏幕

RHEL 7.3 64位。安裝程序進入安裝屏幕，進度條，我看到的最後一件事是它正在下載一些Docker文件。當我回來的時候檢查就可以了，我看到的是一個空白屏幕：在Linux上安裝Db2 Developer Community Edition的空白屏幕

幫助菜單說，安裝程序版本1.1.2（2017年7月21日）。安裝程序被root身份運行，這裏是控制檯：

# ./ibm-db2-developer_community_edition-1.1.2-x86_64.AppImage

in the prod if statement

它已經掛像這一段時間和過程不使用任何CPU。

編輯：我重新運行安裝程序，並且這次更仔細地觀察它。現在，它停留在18％：

每5秒鐘關於，ibm-db2-develop彈出以相當高的CPU幾秒鐘。我附上strace的與strace -f -tt -o outputfile.txt -p ${PID}，我注意到在讀取系統調用一些HTTP 404和429s：

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

它看起來像大部分請求是某種速度測試中，雖然一些似乎與Docker容器：

編輯：我用的strace的-s參數傾倒更多的響應和容器請求都返回404：

[pid 21477] 14:45:35.713220 read(66, "HTTP/1.1 404 Not Found\r\nContent-Type: text/plain; charset=utf-8\r\nServer: Docker/1.10.2 (linux)\r\nX-Content-Type-Options: nosniff\r\nDate: Tue, 05 Sep 2017 21:45:35 GMT\r\nContent-Length: 23\r\nConnection: close\r\n\r\nNo such container: dsm\n", 65536) = 230 
[pid 21477] 14:45:35.714067 read(67, "HTTP/1.1 404 Not Found\r\nContent-Type: text/plain; charset=utf-8\r\nServer: Docker/1.10.2 (linux)\r\nX-Content-Type-Options: nosniff\r\nDate: Tue, 05 Sep 2017 21:45:35 GMT\r\nContent-Length: 29\r\nConnection: close\r\n\r\nNo such container: db2server\n", 65536) = 236

解決方法是禁用SELinux：

sudo setenforce Permissive

我已經證實了這一點，併成功安裝該產品：

$ docker ps 
CONTAINER ID  IMAGE     COMMAND     CREATED    STATUS    PORTS         NAMES 
a6897b6ff68f  dsm:v2.1.4_2    "/opt/start_dsm.sh"  16 hours ago  Up About an hour 0.0.0.0:11080-11082->11080-11082/tcp dsm

@戈文德 - samrow請解釋爲什麼要刪除有效的答案。 – kgibm

@chunjef請解釋你爲什麼推薦刪除。 – kgibm

'sudo setenforce Permissive'在Centos 7上重新啓動後還能存活嗎？ – mao
