gitlab搭建

背景

学习devops，需要搭建一个仓库。

版本选择

云上资源较小，选用旧版本的gitlab7，实测搭建后内存占用为800M左右。发现还有其他的仓库应用Gitea，后面尝试下。

搭建

# 依赖安装
sudo yum install -y curl policycoreutils openssh-server openssh-clients postfix
sudo systemctl enable sshd
sudo systemctl start sshd
sudo systemctl enable postfix
sudo systemctl start postfi

# 添加GitLab存储库并安装GitLab
curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
sudo yum install gitlab-ce-7.14.3-ce.1.el7.x86_64

# 修改配置
vi /etc/gitlab/gitlab.rb

gitlab 占用那些端口

HTTP/S端口：80/443

GitLab通过HTTP/S协议进行通信，因此需要开放HTTP（端口号80）和HTTPS（端口号443）端口。HTTP端口用于GitLab未启用HTTPS的情况，而HTTPS端口则用于启动了HTTPS的情况。如果您还没有自己的SSL证书，可以使用GitLab提供的自签名证书。

SSH端口：22

GitLab使用SSH协议进行代码提交、合并等操作，因此需要开放SSH端口号（22）。您可以使用OpenSSH等工具连接到服务器，进行相关操作。

SMTP端口：25

GitLab支持SMTP邮件服务，在注册、密码重置等过程中会用到。SMTP端口号默认为25。

Git端口：9418

GitLab通过Git协议进行代码的传输和管理。Git客户端可以通过此端口连接到GitLab服务器进行代码推送和拉取操作。Git端口号默认为9418。

NFS端口：2049

GitLab可以使用NFS（Network File System）来管理开发者之间的代码共享，而NFS协议默认使用2049端口进行通信。

Redis端口：6379

GitLab使用Redis来缓存会话数据等信息。Redis端口号默认为6379。

PostgreSQL端口：5432

GitLab使用PostgreSQL来存储代码库和其他相关数据，如用户、项目、组等。PostgreSQL端口号默认为5432。

sudo yum install -y --nogpgcheck gitlab-ce-7.14.3-ce.1.el7.x86_64 # nogpgcheck解决证书问题

# 开机启动
sudo systemctl enable gitlab-runsvdir.service
# 取消开机启动
sudo systemctl disable gitlab-runsvdir.service

# 启动
sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart

# 查看状态
sudo gitlab-ctl status

# 关闭
sudo gitlab-ctl stop

# 初始用户和密码
cat /etc/gitlab/initial_root_password #先尝试这个看看有没有
gitlab-rake "gitlab:setup[force-init=admin]" # 创建一个用户，画面会打印账号密码
gitlab-rake "gitlab:setup[password=admin]" # 若上面命令失败，重置admin用户的密码
