本篇內容介紹了“DevOps版本控制系統GitLab部署方法是什么”的有關知識,在實際案例的操作過程中,不少人都會遇到這樣的困境,接下來就讓小編帶領大家學習一下如何處理這些情況吧!希望大家仔細閱讀,能夠學有所成!
使用RPM包部署
這里使用的系統是CentOS8
## 下載軟件包 wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el8/gitlab-ce-13.7.0-ce.0.el8.x86_64.rpm ## 安裝 rpm -ivh gitlab-ce-13.7.0-ce.0.el8.x86_64.rpm ## 日志輸出 warning: gitlab-ce-13.7.0-ce.0.el8.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID f27eab47: NOKEY Verifying... ################################# [100%] Preparing... ################################# [100%] Updating / installing... 1:gitlab-ce-13.7.0-ce.0.el8 ################################# [100%] It looks like GitLab has not been configured yet; skipping the upgrade script. *. *. *** *** ***** ***** .****** ******* ******** ******** ,,,,,,,,,***********,,,,,,,,, ,,,,,,,,,,,*********,,,,,,,,,,, .,,,,,,,,,,,*******,,,,,,,,,,,, ,,,,,,,,,*****,,,,,,,,,. ,,,,,,,****,,,,,, .,,,***,,,, ,*,. _______ __ __ __ / ____(_) /_/ / ____ _/ /_ / / __/ / __/ / / __ `/ __ \ / /_/ / / /_/ /___/ /_/ / /_/ / \____/_/\__/_____/\__,_/_.___/ 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: https://gitlab.fra1.qualtrics.com/jfe/form/SV_6kVqZANThUQ1bZb?installation=omnibus&release=13-7
配置
安裝完成后可以發現以下信息,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
編輯 /etc/gitlab/gitlab.rb 可以看到默認的域名配置。如果是學習使用則可以繼續使用該域名,不用再做其他配置。
32 external_url 'http://gitlab.example.com'
如果是需要修改該域名,則需要這樣做:
## 修改gitlab.rb external_url 'http://gitlab.devops.com' ## 重新配置 gitlab-ctl reconfigure
服務運行控制
## 啟動服務 gitlab-ctl start ## 重啟服務 gitlab-ctl restart ## 查看狀態 gitlab-ctl status ## 停止 gitlab-ctl stop
訪問測試
由于使用的是gitlab.devops.com 這個域名,需要在dns或者本地hosts中添加該解析記錄。
vi /etc/hosts 192.168.1.200 gitlab.devops.com
瀏覽器訪問http://gitlab.devops.com/, 設置用戶密碼。默認用戶root。這里設置的密碼是devops1234。
能夠正常進入首頁即可,安裝完成。
擴展:使用外部PG數據庫
使用docker快速啟動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 ## 創建數據庫 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用戶創建 EXTENSION, btree_gist, pg_trgm。否則會遇到如下錯誤:
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
編輯/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
驗證配置生效
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
