1. gitlab and generate the ssh key github

ssh-keygen -t rsa -C "[email protected]" -b 4096

 

The first generation of gitlab ssh key way to enter to generate a ssh key second github should pay attention to what the name of ssh key needs to be modified a bit, otherwise it will cover gitlab front of key generation, and here I modified id_rsa_github

This time you can see the ~ / .ssh / directory created under the following files

 

- id_rsa
- id_rsa.pub 
- id_rsa_github
- id_rsa_github.pub

2. Copy the contents of each public key, add the ssh key in gitlab and in github

cat ~/.ssh/id_rsa.pub

3. Add the config file

Create a config file in the .ssh / directory

vim config

Add the configuration, content

# gitlab
Host gitlab
    User git
    HostName gitlab.cheanjiait.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa

# github
Host github
    User git
    HostName github.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa_github

4. Test connector

$ ssh -T gitlab
Welcome to GitLab, Ethan Chen!

$ ssh -T github
Hi azumia! You've successfully authenticated, but GitHub does not provide shell access.

If the above occurs, it means the connection is successful, then you can git out the happy

 

Precautions

When using github, git in the project initialization time to remember the definition of good user.name and user.email

git config --local user.name 'aaa'
git config --local user.email '[email protected]'

 

If the test connection failed, Permission denied (publickey). The reason is that they have customized id_rsa_github key name, by default, the connection will search id_rsa key name, so here fail

 

Specific reasons for the failure may be connected by understanding the following

ssh -T -v [email protected] 

 

Solutions to this problem are as follows

Open ssh-agent

# Enable Agent 
eval $ ( SSH-Agent - S) ← ┘ 
Agent pid 8428

# Add key name
 SSH-the Add ~ /. SSH / id_rsa_github ← ┘ 
the Identity added: / c / the Users / the User /. SSH / id_rsa_github (/ c / the Users / the User /. SSH / id_rsa_github)

 

# Agent can be closed when not in use 
eval $ ( SSH-agent - k) ← ┘ 
Agent pid 8428 killed

 

If the initialization time to report the following error warehouse

ssh: Could not resolve hostname https: nodename nor servname provided, or not known
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

 

Then look at your git configuration

$ git remote -v

The address by the git ssh mode to https way to
