如何通过主站登录DC-OS从站 [英] How to login into DC-OS slave through Master
问题描述
我在azure上创建了DC-OS集群,使用ssh公钥创建后,我可以使用以下命令访问master, 须藤ssh -v -A -p 2200 user @ master-ip -i/root/.ssh/id_rsa
I created DC-OS cluster on azure, after creating with ssh public key I can access to master with the following commands, sudo ssh -v -A -p 2200 user@master-ip -i /root/.ssh/id_rsa
进入主服务器后,我想访问代理,因此我将id_rsa和id_rsa.pub密钥从主机复制到了主节点. 并运行以下命令.
After getting into Master I want to access agents so I copied id_rsa and id_rsa.pub key from host to master node. and run the following command.
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(公钥)
ssh -p 22 10.32.0.4 debug1: No more authentication methods to try. Permission denied (public key)
但是不幸的是,它会产生以下错误,我已经尝试了很多方法,但是没有屈从于此.
but unfortunately it will give following error, I have tried so many ways but didn't ssh into the salve.
推荐答案
我们可以按照以下步骤操作SSH代理:
1. 上传私钥到主密钥,我将私钥(222222)上载到此目录:
We can follow those steps to SSH agent:
1.Upload private key to master, I upload private key(222222) to this directory:
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.对该私有密钥的更改权限,更改为 600 :
2.change permission for this private key, change to 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.使用此密钥连接SSH代理:
3.Use this key to SSH agent:
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)

注意:
1.我们可以使用CLI 2.0查找VMSS的实例管理员用户名,与您的主管理员用户名:
Note:
1.We can use CLI 2.0 to find the VMSS' instance admin user name, the name same as your master admin user:
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.此外,我们还应该检查私钥许可,我们应该将其设置为 600 .
3.确保.ssh
目录权限为 700 或 755 .
2.Also we should check the private key permission, we should set it to 600.
3.Make sure .ssh
directory permission is 700 or 755.
