使用pssh

简要范例

  • pssh 在多个主机上并行地运行命令。
    • pssh -h hosts.txt -l irb2 -o /tmp/foo uptime
  • pscp 传输文件到多个主机，类似scp。
    • pscp -h hosts.txt -l irb2 foo.txt /home/irb2/foo.txt
  • pslurp 从多个主机拷贝到本地。
    • Example: pslurp -h hosts.txt -L /tmp/outdir -l irb2 /home/irb2/foo.txt foo.txt
  • pnuke 在多个主机并行地杀进程。
    • pnuke -h hosts.txt -l irb2 java
  • prsync 使用rsync协议从本地同步到远程主机。
    • prsync -r -h hosts.txt -l irb2 foo /home/irb2/foo
  • 避免ssh检查host keys：
    1
    2
    3
    pssh -i -H host1 -H host2 \
    -x "-O StrictHostKeyChecking=no -O UserKnownHostsFile=/dev/null -O GlobalKnownHostsFile=/dev/null" \
    echo hi
    • 也可以加到.ssh/config
      1
      2
      3
      4
      5
      cat >>~/.ssh/config <<EOF
      StrictHostKeyChecking=no
      UserKnownHostsFile=/dev/null
      GlobalKnownHostsFile=/dev/null
      EOF
  • host文件格式

    # 每行一个主机，格式： [user@]host[:port]
