如何通过Master登录DC-OS slave

Question

我在 azure 上创建了 DC-OS 集群，在使用 ssh public 密钥创建后，我可以使用以下命令访问 master， sudo ssh -v -A -p 2200 user@master-ip -i /root/.ssh/id_rsa

进入主节点后我想访问代理，所以我将 id_rsa 和 id_rsa.pub 密钥从主机复制到主节点。和运行以下命令。

ssh -p 22 10.32.0.4 debug1：没有更多的身份验证方法可以尝试。权限被拒绝（public 键）

但不幸的是它会给出以下错误，我尝试了很多方法但没有ssh进入药膏。

Answer 1

我们可以按照以下步骤访问 SSH 代理：
1.上传私钥给master，我上传私钥(222222)到这个目录：

root@dcos-master-B9E522B-0:/home/jason/.ssh# pwd
/home/jason/.ssh
root@dcos-master-B9E522B-0:/home/jason/.ssh# ls
222222  authorized_keys  known_hosts
root@dcos-master-B9E522B-0:/home/jason/.ssh#

2.更改此私钥的权限，更改为600:

jason@dcos-master-B9E522B-0:~/.ssh$ ll -a
total 20
drwx------ 2 jason jason 4096 Apr 27 02:39 ./
drwxr-xr-x 4 jason jason 4096 Apr 27 02:39 ../
-rw-rw-r-- 1 jason jason 1675 Apr 27 02:38 222222
-rw------- 1 jason jason  381 Apr 27 02:17 authorized_keys
-rw-r--r-- 1 jason jason  222 Apr 27 02:35 known_hosts
jason@dcos-master-B9E522B-0:~/.ssh$ chmod 600 222222

3.Use SSH 代理的密钥：

jason@dcos-master-B9E522B-0:~/.ssh$ ssh jason@10.32.0.4 -i /home/jason/.ssh/222222 
ssh: /opt/mesosphere/lib/libcrypto.so.1.0.0: no version information available (required by ssh)
ssh: /opt/mesosphere/lib/libcrypto.so.1.0.0: no version information available (required by ssh)

注:
1.We 可以使用 CLI 2.0 找到 VMSS 的实例管理员用户名，与您的主管理员用户相同的名称:

C:\Users>az vmss list-instances -n "dcos-agent-private-B9E522B-vmss0" -g dcos
"osProfile": {
      "adminPassword": null,
      "adminUsername": "jason",
      "computerName": "dcos-agent-private-B9E522B000000",

2.Also我们应该检查私钥权限，我们应该将其设置为600.
3.Make确定.ssh目录权限为700或755.
