问题：socket模块获取ip失败报错
In [64]: import socket In [71]: socket.gethostname() Out[71]: ‘web01‘ In [72]: host_name = socket.gethostname() In [73]: socket.gethostbyname(host_name) --------------------------------------------------------------------------- gaierror Traceback (most recent call last) <ipython-input-73-52ba2e5a9213> in <module>() ----> 1 socket.gethostbyname(host_name) gaierror: [Errno -2] Name or service not known
解决办法：
修改配置文件/etc/hosts，增加主机名与IP解析，如下：10.0.0.22 web01
(venv1) [root@web01 bin]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.0.0.22 web01
即可解决！！！！！
In [74]: socket.gethostbyname(host_name) Out[74]: ‘10.0.0.22‘
