把认为哪个个分支不想让别人动，就把这个分支设置为保护分支，并且只有授权的用户才可以向这个分支推送代码

在实际使用过程中，我们通常会保持 master 分支稳定，用于生产环境的版本发布， 只有授权的用户 才可以向 master 合并代码。

要实现此功能，我们需要将 master 设置为保护分支，并 授权什么用户 可以向 master 用户推送代码。

使用 root 用户点击 git_test 仓库页面左下角的 Settings

进入设置页面，选择设置菜单栏下面的 Repository 选项

[root@ci- node2 git_test]# git checkout master Switched to branch ' master ' Your branch is up -to- date with ' origin/master '

创建新文件，然后提交，在ci-node2客户端推送

[root@ci-node2 git_test]# touch ci-node2
[root@ci-node2 git_test]# git add .
[root@ci-node2 git_test]# git commit -m "commit ci-node2 on ci-node2"
[master 2bd2e88] commit ci-node2 on ci-node2
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 ci-node2

我们发现此时我们已经不能在 ci-node2 上向 GitLab 上推送 master 分支，因为我们ci-node2 绑定的是 dev 用户，dev 用户属于 developer 角色，

master 分支不允许 developer角色向其推送内容。

[root@ci-node2 git_test]# git push -u origin master

Compressing objects: 100% (2/2), done.
Writing objects: 100% (2/2), 234 bytes | 0 bytes/s, done.

 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@192.168.31.11:test/git_test.git

在dev分支

[root@ci-node2 git_test]# git branch
* dev
  master

[root@ci-node2 git_test]# ll
total 4
-rw-r--r-- 1 root root 21 Mar 30 00:11 a
-rw-r--r-- 1 root root  0 Mar 30 00:34 dev
-rw-r--r-- 1 root root  0 Mar 30 00:11 master
-rw-r--r-- 1 root root  0 Mar 30 00:11 test

创建一个文件然后提交

[root@ci-node2 git_test]# touch ci-node2

[root@ci-node2 git_test]# ll
total 4
-rw-r--r-- 1 root root 21 Mar 30 00:11 a
-rw-r--r-- 1 root root  0 Apr  1 23:05 ci-node2
-rw-r--r-- 1 root root  0 Mar 30 00:34 dev
-rw-r--r-- 1 root root  0 Mar 30 00:11 master
-rw-r--r-- 1 root root  0 Mar 30 00:11 test


[root@ci-node2 git_test]# git add .
[root@ci-node2 git_test]# git commit -m "touch ci-node2 file on dev branch"
[dev be5cdbe] touch ci-node2 file on dev branch
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 ci-node2

推送到dev用户

[root@ci-node2 git_test]# git push -u origin dev
Counting objects: 2, done.
Compressing objects: 100% (2/2), done.
Writing objects: 100% (2/2), 247 bytes | 0 bytes/s, done.

切换到master分支

[root@ci-node2 git_test]# git checkout master
Switched to branch 'master'

把dev分支合并到master 分支

[root@ci-node2 git_test]# git merge dev
Updating cc7da0e..be5cdbe
Fast-forward
 ci-node2 | 0
 dev      | 0
 2 files changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 ci-node2
 create mode 100644 dev

推送到master分支

报错原因因为ci-node2 公钥绑定gitlab dev用户上，gitlab上设置dev用户是开发者，开发者没有权限推送到master

[root@ci-node2 git_test]# git push -u origin master
Total 0 (delta 0), reused 0 (delta 0)
remote: GitLab: You are not allowed to push code to protected branches on this project.
To 192.168.31.11:test/git_test.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@192.168.31.11:test/git_test.git'

回到ci-node1 上推master分支

[root@ci-node1 git_test]# git push -u gitlab master
Branch master set up to track remote branch master from gitlab.
Everything up-to-date

ci-node2 上做了修改推送了仓库内容，ci-node1现在本地仓库和远程仓库内容不一致，导致以上情况

这时候需要用git fetch命令

git fetch 使用

上面我们在 ci-node2 向 gitlab 上的远程仓库推送了新的内容，此时对于 ci-node1 上的 git_test 仓库来说，它的远程仓库已经更新，所以需要将这些更新取回本地，这时就需要用到 git fetch 命令。

fetch到本地，然后合并，再推送

[root@ci-node1 git_test]# git fetch

remote: Compressing objects: 100% (4/4), done.
remote: Total 4 (delta 1), reused 0 (delta 0)

From 192.168.31.11:test/git_test
 * [new branch]      dev        -> gitlab/dev

合并把更新内容合并到本地

[root@ci-node1 git_test]# git merge gitlab/dev
Updating cc7da0e..be5cdbe
Fast-forward
 ci-node2 | 0
 dev      | 0
 2 files changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 ci-node2
 create mode 100644 dev

有ci-node2文件

[root@ci-node1 git_test]# ll
total 4
-rw-r--r-- 1 root root 21 Mar 21 23:53 a
-rw-r--r-- 1 root root  0 Apr  2 23:49 ci-node2
-rw-r--r-- 1 root root  0 Apr  2 23:49 dev
-rw-r--r-- 1 root root  0 Mar 21 18:31 master
-rw-r--r-- 1 root root  0 Mar 18 00:20 test

[root@ci-node1 git_test]# git push -u gitlab master
Total 0 (delta 0), reused 0 (delta 0)
To 192.168.31.11:test/git_test.git
   cc7da0e..be5cdbe  master -> master
Branch master set up to track remote branch master from gitlab.

再看看gitlab 有ci-node2文件

现在ci-node1 客户端上对ci-node2 文件追加内容，提交

[root@ci-node1 git_test]# echo "222" >> ci-node2 
[root@ci-node1 git_test]# git add .
[root@ci-node1 git_test]# git commit -m "modify ci-node2 file on master branch"
[master b5692cb] modify ci-node2 file on master branch
 1 file changed, 1 insertion(+)

[root@ci-node1 git_test]# git push -u gitlab master
Counting objects: 3, done.
Compressing objects: 100% (2/2), done.
Writing objects: 100% (3/3), 273 bytes | 0 bytes/s, done.
Total 3 (delta 1), reused 0 (delta 0)
To 192.168.31.11:test/git_test.git
   be5cdbe..b5692cb  master -> master
Branch master set up to track remote branch master from gitlab

推送成功再去看看 gitlab，推上来了，dev用户推不上来，ci-node1 可以推上来，ci-node1 公钥绑定的是root用户 admin用户，

ci-node2 公钥绑定要dev用户，我们设置master分支只有master角色才能推送

不让dev用户推到master分支，dev用户只能推到dev分支上，做完还可以提个申请，申请把代码合并到master

切换到dev分支

[root@ci-node2 git_test]# git branch
* master
[root@ci-node2 git_test]# git checkout dev
Switched to branch 'dev'
Your branch is up-to-date with 'origin/dev'.
