在ansible中，如何在同一台远程计算机上同步2个文件夹？

标签： ansible rsync ansible-playbook ansible-2.x

我有以下简单的任务：

将文件夹A中的所有内容复制到文件夹B.由于组中有很多主机，因此我使用以下yaml任务定义：

- name: Sync /etc/spark/conf to $SPARK_HOME/conf
  synchronize: src=/etc/spark/conf dest={{spark_home}}/conf
  delegate_to: "{{item}}"
  with_items: "{{play_hosts}}"
  tags: spark

然而，运行ansible-playbook给了我以下错误：

显然，似乎ansible试图在我的所有3个主机之间创建交换对并在每对之间进行同步（因此执行了9个rsync），如何避免这种情况并命令ansible仅在本地执行rsync？

更新：我已将任务定义更改为使用delegate.host：

- name: Sync /etc/spark/conf to $SPARK_HOME/conf
  synchronize: src=/etc/spark/conf dest={{spark_home}}/conf
  delegate_to: delegate.host
  tags: spark

但是ansible引擎显然没有正确解释它，调试日志显示它没有被主机IP地址替代：

  

为用户建立SSH连接：无

     

SSH：EXEC ssh -C -q -o ControlMaster = auto -o   ControlPersist = 60s -o KbdInteractiveAuthentication = no -o   PreferredAuthentications = GSSAPI与 - 麦克风，GSSAPI-keyex，基于主机的，公钥   -o PasswordAuthentication = no -o ConnectTimeout = 10 -o ControlPath = / home / peng / .ansible / cp / ansible-ssh-％h-％p-％r    delegate.host ＆＃39; / bin / sh -c＆＃39;＆＃34;＆＃39;＆＃34;＆＃39;（umask 77＆amp;＆amp; mkdir -p ＆＃34; echo $HOME/.ansible/tmp/ansible-tmp-1470667606.38-157157938048153＆＃34;＆amp;＆amp;   echo ansible-tmp-1470667606.38-157157938048153 =＆＃34; echo $HOME/.ansible/tmp/ansible-tmp-1470667606.38-157157938048153＆＃34; ）＆amp;＆amp;   睡0＆＃39;＆＃39;＆＃39;＆＃39;＆＃39;

这看起来像是一个已弃用的功能，我使用的是ansible 2.1.0.0

答案 0 :(得分：2)

解决：

var gridView1Control = document.getElementById('<%= GridView1.ClientID %>');

$('#<%= btnGetData.ClientID %>').click(function(e) {
    //To uncheck the header checkbox when there are no selected checkboxes in itemtemplate
    $('input:checkbox[id$=CheckSelect]:checked', gridView1Control).each(function(item, index) {

        var id = $(this).next('input:hidden[id$=hdID]').val();
        alert(id);
    });
    return false;

});

可能会删除delegate.host以支持新变量
