pssh，超时，被信号 9 杀死

Question

我在其他机器上使用PSSH到运行命令来实现parallel compute使用IPyParallel，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，它返回：

[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

谷歌搜索后，我发现如果不输入-t选项，pssh命令只会持续60秒。所以，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

并且该命令将在 100000000 秒后被终止

感谢@Nicolas Thery and @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

-t timeout
--timeout timeout
Make connections time out after the given number of seconds. With a value of 0, pssh will not timeout any connections.

Answer 3

将 pssh 的超时设置为 0 以禁用默认的 60 秒超时。 -t 0

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

最上面的答案表明超时非常长，您可以将其禁用。

pssh，超时，被信号 9 杀死

pssh, Time out, killed by signal 9
