Unable to connect to host 127.0.0.1 on port 7056 after 45000 ms by manual create session
我在同一台机器上启动集线器和节点，并在 firefox 浏览器上打开 http://localhost:5555/wd/hub/static/resource/hub.html。我创建了 Firefox 会话，但它提醒我 "Unable to create new session.".
这是我的日志。

我将 firefox 10 与 selenium-server-standalone-2.45 一起使用。0.jar。
我该怎么办？
好吧，我已经解决了这个问题。
在我的日志中它说 "Error: no display specified"
因为 DISPLAY 变量没有值，
因此，当我启动集线器和节点时，我改用以下命令。
export DISPLAY=":1" && java -jar selenium-server-standalone-2.45.0.jar -role hub
和
export DISPLAY=":1" && java -jar selenium-server-standalone-2.45.0.jar -role node -hub http://localhost:4444/grid/register
我在同一台机器上启动集线器和节点，并在 firefox 浏览器上打开 http://localhost:5555/wd/hub/static/resource/hub.html。我创建了 Firefox 会话，但它提醒我 "Unable to create new session.".
