So I switched to searching for the ip address by referencing the Mac address. The best solution so far is to use nmap and parse the results. My

阅读更多关于使用ansible批量修改主机名后/etc/hosts文件不能被正确修改的修复方法

我前面一篇文章讲述了如何这ansible中批量修改主机名，但是上面没有经过严格的测试。使用hostname模块修改主机名之后，/etc/hosts里的内容是并没有修改的这里会造成一个问题，如果hosts里的的主机名没有被绑定，那么我们SSH的时候会造成问题，出现主机名无法解析的现象解决办法。我这里是ubuntu的机器 centos的还没测试过 jastme@jastme2:~$ more /etc/nsswitch.conf # /etc/nsswitch.conf # # Example configuration of GNU Name Service Switch functionality. # If you have the `glibc-doc-reference' and `info' packages installed, try: # `info libc "Name Service Switch"' for information about this file. passwd: compat group: compat shadow: compat #hosts: files dns 换成下面的，取消DNS的解析 hosts: files networks: files protocols: db files services: db files
