pssh可以在控制机上并行执行命令吗？
现在我有三台机器。
这是我的
hostpssh文件。它们对应于druidcluster1,druidcluster2,druidcluster4。

ssh互信都建立了，包括ssh对每台机器本身的信任：
[root@druidcluster1 generalsoftware]# ssh druidcluster1 date
Sun May 12 02:02:49 CDT 2019
[root@druidcluster1 generalsoftware]# ssh druidcluster2 date
Sun May 12 02:02:55 CDT 2019
[root@druidcluster1 generalsoftware]# ssh druidcluster4 date
Sun May 12 02:03:01 CDT 2019
[root@druidcluster2 .ssh]# ssh druidcluster2 date
Sun May 12 02:02:19 CDT 2019
[root@druidcluster2 .ssh]# ssh druidcluster1 date
Sun May 12 02:02:25 CDT 2019
[root@druidcluster2 .ssh]# ssh druidcluster4 date
Sun May 12 02:02:31 CDT 2019
[root@druidcluster4 .ssh]# ssh druidcluster4 date
Sun May 12 02:02:01 CDT 2019
[root@druidcluster4 .ssh]# ssh druidcluster1 date
Sun May 12 02:02:08 CDT 2019
[root@druidcluster4 .ssh]# ssh druidcluster2 date
Sun May 12 02:02:14 CDT 2019
然后我执行pssh -h hostpssh -P date并druidcluster1得到：
[root@druidcluster1 generalsoftware]# pssh -h hostpssh -P date

只是控制机上的命令失败了。
