将GitHub代码同步到Gitee上，并同步更新

创建Gitee仓库

我本来已经有GitHub仓库了，现在要在Gitee上创建，可以选择直接从GitHub上导入，如下：

这样，Gitee上就有跟GitHub上一样的代码了。

同步更新代码

先查看当前远程的路径是什么：

$ git remote -v
origin  git@github.com:LarryDpk/pkslow-samples.git (fetch)
origin  git@github.com:LarryDpk/pkslow-samples.git (push)

添加Gitee的地址：

$ git remote set-url --add origin git@gitee.com:larrydpk/pkslow-samples.git

再次查看就有两个地址了：

$ git remote -v
origin  git@github.com:LarryDpk/pkslow-samples.git (fetch)
origin  git@github.com:LarryDpk/pkslow-samples.git (push)
origin  git@gitee.com:larrydpk/pkslow-samples.git (push)

我们随便更新一个文件，然后提交：

$ git commit -m "add gitee url"
[master 4982dc5] add gitee url
 1 file changed, 3 insertions(+)

推送代码：

看日志就知道已经成功推送到两个远程的仓库了。

同步更新的另一种配置方式

除了命令行，我们还可以通过配置文件来实现：

$ cat .git/config
[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
        ignorecase = true
        precomposeunicode = true
[remote "origin"]
        url = git@github.com:LarryDpk/pkslow-samples.git
        fetch = +refs/heads/*:refs/remotes/origin/*
        url = git@gitee.com:larrydpk/pkslow-samples.git
[branch "master"]
        remote = origin
        merge = refs/heads/master

我们还可以添加多个remote，这样可以单独推送：

[core]
	repositoryformatversion = 0
	filemode = true
	bare = false
	logallrefupdates = true
	ignorecase = true
	precomposeunicode = true
[remote "origin"]
	url = git@github.com:LarryDpk/pkslow-samples.git
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@gitee.com:larrydpk/pkslow-samples.git
[remote "github"]
	url = git@github.com:LarryDpk/pkslow-samples.git
	fetch = +refs/heads/*:refs/remotes/origin/*
[remote "gitee"]
	url = git@gitee.com:larrydpk/pkslow-samples.git
	fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
	remote = origin
	merge = refs/heads/master

单独推送如下：

$ git remote -v
gitee   git@gitee.com:larrydpk/pkslow-samples.git (fetch)
gitee   git@gitee.com:larrydpk/pkslow-samples.git (push)
github  git@github.com:LarryDpk/pkslow-samples.git (fetch)
github  git@github.com:LarryDpk/pkslow-samples.git (push)
origin  git@github.com:LarryDpk/pkslow-samples.git (fetch)
origin  git@github.com:LarryDpk/pkslow-samples.git (push)
origin  git@gitee.com:larrydpk/pkslow-samples.git (push)

$ git push github
Everything up-to-date

$ git push gitee
Everything up-to-date

当然，上面的操作都基于配置了ssh key，且是同一个Key。
