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

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

##安装

rpm-ivhgitlab-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:HeaderV4RSA/SHA256Signature,keyIDf27eab47:NOKEY

ThankyouforinstallingGitLab!

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。

32external_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-ctlreconfigure

服务运行控制

##启动服务

gitlab-ctlstart

##重启服务

gitlab-ctlrestart

##查看状态

gitlab-ctlstatus

##停止

gitlab-ctlstop

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

192.168.1.200gitlab.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

dockerrun–namedockerPG11

-ePOSTGRES_PASSWORD=postgres

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

-p54322:5432

-dpostgres:11.5

##创建数据库

psql-Upostgres-hlocalhost-p54322

psql(11.5(Debian11.5-3.pgdg90+1))

Type"help"forhelp.

postgres=#createrolegitlabloginencryptedpassword'gitlab';

CREATEROLE

postgres=#createdatabasegitlabhq_productionowner=gitlabENCODING='UTF8';

CREATEDATABASE

postgres=#cgitlabhq_production

Youarenowconnectedtodatabase"gitlabhq_production"asuser"postgres".

gitlabhq_production=#CREATEEXTENSIONIFNOTEXISTSbtree_gist;

CREATEEXTENSION

gitlabhq_production=#CREATEEXTENSIONIFNOTEXISTSpg_trgm;

CREATEEXTENSION

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

654gitlab_rails['db_adapter']="postgresql"

655gitlab_rails['db_encoding']="utf8"

656#gitlab_rails['db_collation']=nil

657gitlab_rails['db_database']="gitlabhq_production"

658gitlab_rails['db_username']="gitlab"

659gitlab_rails['db_password']="gitlab"

660gitlab_rails['db_host']="192.168.1.200"

661gitlab_rails['db_port']=54322

1025postgresql['enable']=false

##配置更新

gitlab-ctlreconfigure

验证配置生效

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

#Thisfileismanagedbygitlab-ctl.Manualchangeswillbe
