DevOps-版本控制系统-GitLab部署

使用RPM包部署

这里使用的系统是CentOS8，清华源：mirrors.tuna.tsinghua.edu.cn/gitlab-ce/

## 下载软件包

wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el8/gitlab-ce-13.7.0-ce.0.el8.x86_64.rpm

## 安装

rpm -ivh gitlab-ce-13.7.0-ce.0.el8.x86_64.rpm

## 日志输出

warning: gitlab-ce-13.7.0-ce.0.el8.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID f27eab47: NOKEY

Thank you for installing GitLab!

GitLab was unable to detect a valid hostname for your instance.

Please configure a URL for your GitLab instance by setting `external_url`

configuration in /etc/gitlab/gitlab.rb file.

Then, you can start your GitLab instance by running the following command:

  sudo gitlab-ctl reconfigure

For a comprehensive list of configuration options please see the Omnibus GitLab readme

https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md

Help us improve the installation experience, let us know how we did with a 1 minute survey:

配置

安装完成后可以发现以下信息，需要修改gitlab.rb配置文件。

GitLab was unable to detect a valid hostname for your instance. Please configure a URL for your GitLab instance by setting external_urlconfiguration in /etc/gitlab/gitlab.rb file. Then, you can start your GitLab instance by running the following command: sudo gitlab-ctl reconfigure

编辑 /etc/gitlab/gitlab.rb 可以看到默认的域名配置。如果是学习使用则可以继续使用该域名，不用再做其他配置。

32 external_url 'http://gitlab.example.com'

如果是需要修改该域名，则需要这样做：

## 修改gitlab.rb

external_url 'http://gitlab.devops.com'

## 重新配置

gitlab-ctl reconfigure

服务运行控制

## 启动服务

gitlab-ctl start

## 重启服务

gitlab-ctl restart

## 查看状态

gitlab-ctl status

## 停止

gitlab-ctl stop

访问测试

由于使用的是gitlab.devops.com 这个域名，需要在dns或者本地hosts中添加该解析记录。

vi /etc/hosts

192.168.1.200 gitlab.devops.com

浏览器访问http://gitlab.devops.com/, 设置用户密码。默认用户root。这里设置的密码是devops1234。

能够正常进入首页即可，安装完成。

扩展：使用外部PG数据库

使用docker快速启动PG

You are using PostgreSQL 9.6.16, but PostgreSQL >= 11 is required for this version of GitLab.

mkdir /root/gitlab/pgdata

docker run --name dockerPG11

-e POSTGRES_PASSWORD=postgres

-v /root/gitlab/pgdata:/var/lib/postgresql/data

-p 54322:5432

-d postgres:11.5

## 创建数据库

psql -U postgres -h localhost -p 54322

psql (11.5 (Debian 11.5-3.pgdg90+1))

Type "help" for help.

postgres=# create role gitlab login encrypted password 'gitlab';

CREATE ROLE

postgres=# create database gitlabhq_production owner=gitlab ENCODING = 'UTF8';

CREATE DATABASE

postgres=# c gitlabhq_production

You are now connected to database "gitlabhq_production" as user "postgres".

gitlabhq_production=# CREATE EXTENSION IF NOT EXISTS btree_gist;

CREATE EXTENSION

gitlabhq_production=# CREATE EXTENSION IF NOT EXISTS pg_trgm;

CREATE EXTENSION

postgres=# q

使用postgres用户创建 EXTENSION, btree_gist, pg_trgm。否则会遇到如下错误：

STDOUT: psql:/opt/gitlab/embedded/service/gitlab-rails/db/structure.sql:9: ERROR: permission denied to create extension "btree_gist" HINT: Must be superuser to create this extension.

修改gitlab.rb配置文件

编辑/etc/gitlab/gitlab.rb

654 gitlab_rails['db_adapter'] = "postgresql"

655 gitlab_rails['db_encoding'] = "utf8"

656 # gitlab_rails['db_collation'] = nil

657 gitlab_rails['db_database'] = "gitlabhq_production"

658 gitlab_rails['db_username'] = "gitlab"

659 gitlab_rails['db_password'] = "gitlab"

660 gitlab_rails['db_host'] = "192.168.1.200"

661 gitlab_rails['db_port'] = 54322

1025 postgresql['enable'] = false

## 配置更新

gitlab-ctl reconfigure

验证配置生效

cat /opt/gitlab/embedded/service/gitlab-rails/config/database.yml

# This file is managed by gitlab-ctl. Manual changes will be

# erased! To change the contents below, edit /etc/gitlab/gitlab.rb

# and run `sudo gitlab-ctl reconfigure`.

production:

  adapter: postgresql

  encoding: utf8

  collation:

  database: gitlabhq_production

  username: "gitlab"

  password: "gitlab"

  host: "192.168.1.200"

  port: 54322
