意思是主机iZwz9cw7m6bmti17iqpt1pZ这个name或service找不到。
解决方法是在/etc目录下修改hosts文件，修改前的hosts文件内容：

127.0.0.1   localhost

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

只需要添加这两行即可：

127.0.1.1   localhost.localdomain   localhost
127.0.0.1 iZwz9cw7m6bmti17iqpt1pZ

修改后的hosts文件内容：

127.0.0.1   localhost
127.0.1.1   localhost.localdomain   localhost
127.0.0.1 iZwz9cw7m6bmti17iqpt1pZ

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
