azure - 在 ubuntu 16.04 中安装 Varnish

尝试使用 2 种不同的方法在 azure 的 ubuntu 16.04 上设置 Varnish ，但不确定安装方法是否正确。

引用不同的网站似乎都是相同的命令集。

上面的安装是否正确，因为它给出了 发送无效 .

方法二

sudo curl http://repo.varnish-cache.org/debian/GPG-key.txt | sudo apt-key add -
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

gpg: no valid OpenPGP data found.


sudo echo "deb http://repo.varnish-cache.org/ubuntu/ precise varnish-3.0" | sudo tee -a /etc/apt/sources.list

sudo apt-get update

进行更新将导致以下错误。

W: The repository 'http://repo.varnish-cache.org/ubuntu precise Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://repo.varnish-cache.org/ubuntu/dists/precise/varnish-3.0/binary-amd64/Packages  410  repo [IP: 176.58.90.154 80]
E: Some index files failed to download. They have been ignored, or old ones used instead.

不确定这两种方法都是正确的，因为两者都给出了一些错误。

Answer 1

Is the above installation is correct since it gives sent invalidate.

这是关于 Ubuntu 16.04 的已知问题。

当我们尝试将用户添加到 Ubuntu 16.04 ，我们将收到此错误消息，如下所示:

root@ubuntu:~# adduser test
Adding user `test' ...
sent invalidate(passwd) request, exiting
sent invalidate(group) request, exiting
Adding new group `test' (1001) ...
sent invalidate(passwd) request, exiting
sent invalidate(group) request, exiting
sent invalidate(group) request, exiting
sent invalidate(passwd) request, exiting
sent invalidate(group) request, exiting
Adding new user `test' (1001) with group `test' ...
sent invalidate(passwd) request, exiting
sent invalidate(group) request, exiting
sent invalidate(passwd) request, exiting
sent invalidate(group) request, exiting
sent invalidate(passwd) request, exiting
sent invalidate(group) request, exiting

Retype new UNIX password: 
passwd: password updated successfully
Changing the user information for test
Enter the new value, or press ENTER for the default
    Full Name []: 
    Room Number []: 

据我所知，错误消息不会影响它。

jason@ubuntu:~$ su - test
Password: 
test@ubuntu:~$
