2.3安裝gitlab-ceyum?makecache

yum?install?gitlab-ce

2.4查看安裝gitlab的版本head?-1?/opt/gitlab/version-manifest.txt

gitlab-ce?9.1.2

2.5重新配置并啟動Gitlab#?gitlab-ctl?reconfigure會把一些過去的config還原，導致修改的端口以及域名等都沒有了

gitlab-ctl?reconfigure

#重啟gitlab-ce

gitlab-ctl?restart

第3章 安裝mysql5.6.36

3.1添加mysql源vi?/etc/yum.repo.d/mysql.repo

第4章 配置Gitlab連接mysql

4.1修改/etc/gitlab/gitlab.rbpostgresql[‘enable‘]?=?false

gitlab_rails[‘db_adapter‘]?=?‘mysql2‘

gitlab_rails[‘db_encoding‘]?=?‘utf8‘

gitlab_rails[‘db_host‘]?=?‘127.0.0.1‘

gitlab_rails[‘db_port‘]?=?‘3306‘

gitlab_rails[‘db_username‘]?=?‘git‘

gitlab_rails[‘db_password‘]?=?‘123456‘

按官方文檔重新配置gitlab

gitlab-ctl?reconfigure

遷移數據庫時出現以下錯誤

第5章 排錯步驟

5.1更換gem源#查看gem源

/opt/gitlab/embedded/bin/gem?source

***?CURRENT?SOURCES?***

https://rubygems.org/

#更換開源中國的gem源,否則使用時會出現錯誤

/opt/gitlab/embedded/bin/gem?sources?--addhttps://gems.ruby-china.org/?--remove?https://rubygems.org/

#查看更好后的gem源

/opt/gitlab/embedded/bin/gem?sources

***?CURRENT?SOURCES?***

https://gems.ruby-china.org/

#更改配置Gemfile文件的gem源

vi?/opt/gitlab/embedded/service/gitlab-rails/?Gemfile

source?‘https://gems.ruby-china.org‘

5.2bundle install安裝更新#此命令會嘗試更新系統中已存在的gem包

/opt/gitlab/embedded/bin/bundle install

#執行該命令需要切換到Gemfile上一級目錄才可以運行

cd /opt/gitlab/embedded/service/gitlab-rails/

/opt/gitlab/embedded/bin/bundle install

5.3bundle禁止使用postgresqlvi/opt/gitlab/embedded/service/gitlab-rails/.bundle/config

5.4 安裝mysql2 “0.3.20”gitlab-rake?gitlab:check

#安裝mysql2?0.3.20版本

/opt/gitlab/embedded/bin/gem?install?mysql2?-v‘0.3.20‘

出錯

查看文件后發現沒有安裝gcc軟件，導致不能編譯文件。

故需要yum安裝gcc

yum?install?gcc?–y

/opt/gitlab/embedded/bin/gem?install?mysql2?-v‘0.3.20‘

Building?native?extensions.??This?could?take?a?while...
