解决Cannot resolve unit name的错误
根据引用的信息,当你在搭建集群过程中使用ssh连接主机时,可能会遇到"ssh: Could not resolve hostname master: Name or service not known"的报错。这个错误通常是由于主机名解析问题引起的。在你的情况下,你已经修改了主机名为"node1",但是还需要配置/etc/hosts文件才能解决这个问题。你需要将/etc/hosts文件中的"localhost.localdomain"替换为"node1",然后重启机器。这样,ssh连接应该就能成功了。
在引用中,提到了使用松弛应用来运行SSH命令的相关要求。在这个问题中,你遇到的错误与这个引用中提到的松弛应用的配置无关,所以你可以忽略这个引用。
总结来说,你遇到的"ssh: Could not resolve hostname master: Name or service not known"的错误是由于主机名解析问题引起的。通过修改/etc/hosts文件,将"localhost.localdomain"替换为"node1",然后重启机器,你应该能够成功连接到主机了。<span class="em">1</span><span class="em">2</span>
