GitLab在Debian上的集群部署方法

在Debian上部署GitLab集群是一个复杂的过程，需要仔细规划和执行。以下是一个基本的指南，帮助你在Debian系统上部署GitLab集群。

准备工作

1. 更新系统：

   sudo apt-get update
   sudo apt-get upgrade
   

2. 安装必要的依赖包：

   sudo apt-get install curl openssh-server ca-certificates postfix
   

安装GitLab

1. 添加GitLab软件仓库：

   curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash
   

2. 安装GitLab社区版：

   sudo apt-get install gitlab-ce
   

3. 配置GitLab：

   • 找到 /etc/gitlab/gitlab.rb 文件，更改对外访问的域名或IP地址。

   sudo nano /etc/gitlab/gitlab.rb
   

   • 修改以下内容：

     external_url 'http://your-domain-name'
     

   • 保存并退出编辑器，然后重新配置GitLab：

     sudo gitlab-ctl reconfigure
     

4. 启动GitLab服务：

   sudo gitlab-ctl start
   

集群部署

1. 部署Redis：

   • 创建 redis.yaml 文件：

     apiVersion: v1
     kind: Service
     metadata:
       name: redis
       namespace: devops
     labels:
       name: redis
     spec:
       type: ClusterIP
       ports:
         - name: redis
           protocol: TCP
           port: 6379
           targetPort: 6379
       selector:
         name: redis
     ---
     apiVersion: v1
     kind: PersistentVolumeClaim
     metadata:
       name: redis-data
       namespace: devops
     labels:
       app: redis
     spec:
       storageClassName: nfs-storage
       accessModes:
         - ReadWriteOnce
       resources:
         requests:
           storage: 5Gi
     ---
     apiVersion: apps/v1
     kind: Deployment
     metadata:
       name: redis
       namespace: devops
     labels:
       name: redis
     spec:
       replicas: 1
       selector:
         matchLabels:
           name: redis
       template:
         metadata:
           labels:
             name: redis
         spec:
           containers:
             - name: redis
               image: 'redis:6.2'
               ports:
                 - name: redis
                   containerPort: 6379
               volumeMounts:
                 - name: redis-persistent-storage
                   mountPath: /var/lib/redis
           livenessProbe:
             exec:
               command:
                 - redis-cli
                 - ping
               initialDelaySeconds: 5
               timeoutSeconds: 5
               periodSeconds: 10
               successThreshold: 1
               failureThreshold: 3
           readinessProbe:
             exec:
               command:
                 - redis-cli
                 - ping
               initialDelaySeconds: 5
               timeoutSeconds: 5
               periodSeconds: 10
               successThreshold: 1
               failureThreshold: 3
           volumes:
             - name: redis-persistent-storage
               persistentVolumeClaim:
                 claimName: redis-data
     

2. 部署PostgreSQL：

   • 创建 postgresql.yaml 文件：

     apiVersion: v1
     kind: PersistentVolumeClaim
     metadata:
       name: postgresql-data
       namespace: devops
     labels:
       app: postgresql
     spec:
       storageClassName: nfs-storage
       accessModes:
         - ReadWriteOnce
       resources:
         requests:
           storage: 20Gi
     ---
     apiVersion: v1
     kind: Service
     metadata:
       name: postgresql
       namespace: devops
     labels:
       name: postgresql
     spec:
       ports:
         - name: postgres
           protocol: TCP
           port: 5432
           targetPort: 5432
       selector:
         name: postgresql
     ---
     apiVersion: apps/v1
     kind: Deployment
     metadata:
       name: postgresql
       namespace: devops
     labels:
       name: postgresql
     spec:
       replicas: 1
       selector:
         matchLabels:
           name: postgresql
       template:
         metadata:
           labels:
             name: postgresql
         spec:
           containers:
             - name: postgresql
               image: postgres:14
               ports:
                 - name: postgres
                   containerPort: 5432
               volumeMounts:
                 - name: postgresql-persistent-storage
                   mountPath: /var/lib/postgresql
           livenessProbe:
             exec:
               command:
                 - psql
                 - -U
                 - postgres
                 - -c
                 - 'SELECT 1'
               initialDelaySeconds: 5
               timeoutSeconds: 5
               periodSeconds: 10
               successThreshold: 1
               failureThreshold: 3
           readinessProbe:
             exec:
               command:
                 - psql
                 - -U
                 - postgres
                 - -c
                 - 'SELECT 1'
               initialDelaySeconds: 5
               timeoutSeconds: 5
               periodSeconds: 10
               successThreshold: 1
               failureThreshold: 3
           volumes:
             - name: postgresql-persistent-storage
               persistentVolumeClaim:
                 claimName: postgresql-data
     

3. 部署GitLab：

   • 参考 GitLab官方文档 进行Kubernetes环境下的GitLab部署。

访问GitLab

配置完成后，你可以通过浏览器访问你的域名或IP地址，登录GitLab进行管理。

请注意，这只是一个基本的指南，实际部署过程中可能需要更多的配置和优化。建议参考GitLab官方文档和相关的技术社区获取更详细的指导。
