初始化
root@CICD-node1 timinglee# git init
提示：使用 'master' 作为初始分支的名称。这个默认分支名称可能会更改。要在新仓库中
提示：配置使用初始分支名，并消除这条警告，请执行：
提示：
提示： git config --global init.defaultBranch <名称>
提示：
提示：除了 'master' 之外，通常选定的名字有 'main'、'trunk' 和 'development'。
提示：可以通过以下命令重命名刚创建的分支：
提示：
提示： git branch -m <name>

git对于文件如何忽略
在做软件开发时对源码编译会产生一些临时文件，我们在提交时需要忽略这些临时文
root@CICD-node1 timinglee# mkdir dir1/
root@CICD-node1 timinglee# touch dir1/.file2
root@CICD-node1 timinglee# git status -s
?? .file1
?? dir1/

root@CICD-node1 timinglee# echo ".*" > .gitignore

老师的安装方式
(Index of /gitlab/gitlab-ce/el/9/x86_64/Packages/g/)
需要安装包gitlab-ce-18.9.7-ce.0.el9.x86_64.rpm 已经在
C:\Users\姚永强\Desktop\高级课\自己总结的文件\CICID\software
上传到gitlab主机上的root
#在安装包之前需配置好软件仓库来解决依赖性
root@CICD-node1 \~# dnf install -y curl policycoreutils-python-utils openssh-server perl
#由于版本更新，需要安装对应的包，系统的包有依赖又删不掉，知道匹配系统的包了（执行这条命令就行了）
dnf install policycoreutils-python-utils openssh-server perl --nobest
#安装离线安装包，
root@gitlab \~# rpm -ivh gitlab-ce-18.9.7-ce.0.el9.x86_64.rpm
配置gitlab
root@CICD-node1 gitlab# vim /etc/gitlab/gitlab.rb
32
external_url 'http://172.25.254.10' #自己本地电脑的ip
#修改配置文件后需利用gitlab-crt来生效，
root@CICD-node1 gitlab# gitlab-ctl reconfigure
#执行命令成功后会把所有组件全部启动起来
登陆gitlab
用户名默认为 root 。如果在安装过程中指定了初始密码，则用初始密码登录，如果未指定密码，则系统会随机生成一个密码并存储在 /etc/gitlab/initial_root_password 文件中， 查看随机密码并使用 root 用户名登录。
!WARNING
注意：出于安全原因，24 小时后，/etc/gitlab/initial_root_password 会被第一次 gitlab-ctl reconfigure 自动删除，因此若使用随机密码登录，建议安装成功初始登录成功之后，立即修改初始密
#查看原始密码
root@CICD-node1 gitlab# cat /etc/gitlab/initial_root_password
WARNING: This value is valid only in the following conditions
1. If provided manually (either via `GITLAB_ROOT_PASSWORD` environment variable or via `gitlab_rails'initial_root_password'` setting in `gitlab.rb`, it was provided before database was seeded for the first time (usually, the first reconfigure run).
2. Password hasn't been changed manually, either via UI or via command line.
If the password shown here doesn't work, you must reset the admin password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.
Password: jN9lq6NSP8a2V+4n57djzWlEGP7RZ43DSIse8sXJGTQ= #密码
NOTE: This file will be automatically deleted in the first reconfigure run after 24 hours.
