curl不下载所需的文件

Question

我无法下载GitLab的bash脚本。不过，我可以在浏览器中打开链接。

我怎么才能解决这个问题？

[root@localhost ~]# curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.rpm.sh | sudo bash
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

是网络相关的问题吗？

Answer 1

所确定的问题与MSS/MTU有关。我需要在路由器上将mss值调整为1452来修复这个问题。现在所有的用户/服务器都没有这个问题。

Answer 2

重点是Gitlab不支持sslv2和sslv3 anymoe (参见配置>协议下的Gitlab的Qualys检查器报告 )。您的curl、openssl和wget版本试图用过时的协议连接到服务器。

在发生curl的情况下，您可能会强迫客户端使用TLS。尝试以下选项：

--tlsv1
--tlsv1.1
--tlsv1.2
--sslv2 # this will not work on Gitlab
--sslv3 # this will not work on Gitlab

我想你的操作系统是旧的还是过时的。你应该更新你的系统。
