pssh，暂停，被9号信号杀死

Question

我使用PSSH在其他机器上运行命令来实现使用IPyParallel的parallel compute，但是我遇到了一个问题，我的命令是

pssh -P -h ip.txt -i ipengine --file=~/parallel/test/ipcontroller-engine.json

过了一会儿，它又回来了：

[1] 11:54:41 [FAILURE] 192.168.0.112 Timed out, Killed by signal 9

我认为PSSH有问题，但我不知道如何解决。

Answer 1

在googling之后，我发现如果不输入pssh选项，那么-t命令只会持续60秒。因此，为了解决这个问题，我输入命令

pssh -P -h ip.txt -t 100000000 -i ipengine --file=~/parallel/test/ipcontroller-engine.json

100000000秒后命令就会被杀死

谢谢@Nicolas Thery和@Setzer22，您可以设置-t 0来禁用超时功能，而不是设置任意大的值。

Answer 2

将pssh设置为具有0的超时，以禁用默认的60秒超时。-t 0

pssh -P -t 0 -h host_file <COMMAND>

最上面的答案是一个很长的超时时间，当你只需要禁用它。

Answer 3

-t超时--超时使连接在给定的秒数之后超时。如果值为0，pssh将不会超时任何连接。
