spring云配置ssh连接失败

使用SpringBoot、Java1.8、云配置服务器

我试图使用这个application.yml片段访问git回购。但是找不到主机密钥。

spring:
cloud:
    config:
      allowOverride: true
      failFast: true
      overrideNone: true
      overrideSystemProperties: false
      server:
        git:
          uri: ssh://git@10.4.31.179:7999/project/name.git

地址在我的knowHosts文件中:

10.4.31.179:7999,10.4.31.179 ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEA1UF27s4svxRyc3eQVq67hOhl9szwXy15oaUmo5Ndtk9DP5QEvstSA1MR0JotcKrhEHb4FA8a06oRvkyj55zfvr9t96O/sva+66TegPGjiWZNU75LSEKhA8EZ+/VEKVA2Pk1iUEYbtFZZ+SuTKtikXQt0EjghHpx66mWEJU11911+quCfjOIL74tz96IoXBfTZJmhiUQN+SC4UG3bCnha3mMlCnb1/0BkX+YuAy3GN+UTSxCqeEHuwhN8+DsPhVgTKx/YVbhZUPlGlYEUZjjXk6RnyhQr32Jwzv4WpeVu943e2UzlUFMMorl+usur7bSAZWsQWyz6MfjYUyKZkdZYjQ==

你知道为什么这样不行吗?

我认为在您的knowHosts文件中,应该使用如下格式的[host]:port格式

[10.4.31.179]:7999,10.4.31.179 ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEA1UF27s4svxRyc3eQVq67hOhl9szwXy15oaUmo5Ndtk9DP5QEvstSA1MR0JotcKrhEHb4FA8a06oRvkyj55zfvr9t96O/sva+66TegPGjiWZNU75LSEKhA8EZ+/VEKVA2Pk1iUEYbtFZZ+SuTKtikXQt0EjghHpx66mWEJU11911+quCfjOIL74tz96IoXBfTZJmhiUQN+SC4UG3bCnha3mMlCnb1/0BkX+YuAy3GN+UTSxCqeEHuwhN8+DsPhVgTKx/YVbhZUPlGlYEUZjjXk6RnyhQr32Jwzv4WpeVu943e2UzlUFMMorl+usur7bSAZWsQWyz6MfjYUyKZkdZYjQ==

sshd手册页上写着:

主机名或地址可以选择包含在[和]括号内,然后在后面加上:和非标准端口号。

你可以从命令行ssh

ssh 10.4.31.179 -p 7999

然后接受公钥,然后将正确设置knowHosts文件。

如果仍然不起作用,则显式设置知道主机文件。

 jsch.setKnownHosts(knowHostsFileName)

这就是我的解决方案:

>

  • 创建一个~/. ssh/config如下,不要忘记添加StrictHostKeyChecking到false

    Host git
        HostName 10.4.31.179
        StrictHostKeyChecking no
        Port 7999
        User git
        IdentityFile ~/.ssh/id_rsa
    

    应用程序中。yml通过git:/project/name更改uri。git

    spring:
      cloud:
        config:
          allowOverride: true
          failFast: true
          overrideNone: true
          overrideSystemProperties: false
        server:
          git:
            uri: git:/project/name.git

    这是一个相关的GitHub问题和评论。

    TL; DR在尝试连接到存储库服务器之前,需要使用非散列格式更新~/. ssh/known_hosts

    ssh-keyscan -t rsa {hostname or IP} >> ~/.ssh/known_hosts
