Answer 1

"Couldn't resolve host"这是您的dns或互联网连接的问题。

要测试您的互联网连接，您可以测试您是否收到ping的答案：ping 8.8.8.8

要测试您的dns，您可以使用：ping www.google.com

进行测试

如果是因特网连接问题，您可以检查您是否拥有有效网关：ip route show

如果是dns问题，请检查/etc/resolv.conf是否存在以下有效条目： nameserver 8.8.8.8 nameserver 8.8.4.4

Answer 2

我遇到了同样的问题，DNS条目消失就是问题......

尝试#curl http://www.google.com并查看系统是否抛出一个空的resolv.conf文件......

如果是的话，

vi /etc/resolv.conf

...输入 nameserver 8.8.8.8 nameserver 8.8.4.4

或使用您的isp的名称服务器

用yum安装pgadmin3 centos 6

2 个答案:

vi /etc/resolv.conf
