GitLab - 安裝並啓動GitLab

1 - GitLab安裝

1.1 信息確認

[Anliven@node102 ~]$ uname -a
Linux node102 3.10.0-957.el7.x86_64 #1 SMP Thu Nov 8 23:39:32 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
[Anliven@node102 ~]$ cat /etc/system-release
CentOS Linux release 7.5.1804 (Core) 
[Anliven@node102 ~]$

1.2 準備步驟

# 安裝依賴
sudo yum install -y curl policycoreutils-python openssh-server postfix

# 啓動SSH和postfix
sudo systemctl enable sshd
sudo systemctl start sshd
sudo systemctl enable postfix
sudo systemctl start postfix

# 開放端口
sudo firewall-cmd --add-service=ssh --permanent
sudo firewall-cmd --add-service=http --permanent
sudo firewall-cmd --reload

1.3 安裝方式1:Yum

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

1.4 安裝方式2:下載並安裝rpm包

清華鏡像:https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/ html

注意:能夠單獨下載RPM包,而後上傳到Server,要節約時間點。node

wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-12.5.0-ce.0.el7.x86_64.rpm
rpm -i gitlab-ce-12.5.0-ce.0.el7.x86_64.rpm

2 - 初始化配置

GitLab默認的配置文件路徑:/etc/gitlab/python

  • /etc/gitlab/gitlab.rb:主配置文件,包含外部URL、倉庫目錄、備份目錄等
  • /etc/gitlab/gitlab-secrets.json:(執行gitlab-ctl reconfigure命令行後生成),包含各種密鑰的加密信息

2.1 初始化配置

  • 配置首頁地址(需將設置的域名DNS解析到服務器IP,或者修改本地host將域名指向服務器IP)
  • 修改服務端口,避免和其餘服務端口衝突
  • 從新配置並啓動,使配置生效,並確認相關組件或進程的狀態
  • 設置帳號密碼和管理員信息

2.2 登陸

http://192.168.16.102   注意:這個地址是「external_url 'http://192.168.16.102'」 首次登陸顯示爲密碼設置界面,設置管理員密碼,管理員帳號默認username是root 設置完成以後,刷新便可使用root帳號登陸,登錄後會進入歡迎界面。  nginx

2.3 更新管理員資料

2.4 查看管理員面板

Admin Area的主面板顯示總體數據,左側導航菜單能夠查看具體的分類信息 git

2.5 建立新用戶

方式1:管理員直接建立用戶

Admin Area ---》New user,根據規則和須要分別設置Account、Access部分,Password部分能夠由本人進行設置。 redis

查看郵箱,點擊郵件中的連接,設置密碼並登錄 sql

方式2:用戶直接註冊新的帳戶

在GitLab登陸界面,直接點擊「Register」,添加用戶相關信息。 shell

3 - GitLab經常使用配置

3.1 配置Git存儲倉庫目錄

默認存儲目錄爲/var/opt/gitlab/git-data/repositoriesjson

[root@test102 ~]# ll /var/opt/gitlab/git-data/
total 0
drwxrws--- 3 git root 45 Nov 27 13:53 
[root@test102 ~]#

若是要更新或增長存儲倉庫目錄,能夠修改/etc/gitlab/gitlab.rb配置文件中git_data_dirs部分的內容,而後執行「gitlab-ctl reconfigure」命令使之生效。 例如:vim

git_data_dirs({
  "default" => {"path" => "/var/opt/gitlab/git-data"}
  "newrepo" => {"path" => "/mnt/nfs-01/git-data"}
})

特別注意:

  • 若是修改倉庫目錄,用戶有權限訪問,不然從新配置時會報錯。
  • 修改倉庫目錄後,必須將舊倉庫的數據遷移到新目錄下,不然相關項目會提示「沒有倉庫」。
sudo gitlab-ctl upgrade  # 組件更新(可選)
sudo gitlab-ctl stop  # 中止服務
sudo rsync -av <old-dir>  <new-dir>/  # 目錄同步(注意斜槓的做用)
ls <new-dir>  # 檢查文件及目錄層級
sudo gitlab-ctl start  # 啓動服務
sudo gitlab-ctl reconfigure  # 重配置

3.2 配置郵件SMTP

GitLab能夠直接發送郵件,但若是內網對網絡訪問有限制,就須要配置內部的SMTP服務來發送郵件。

[root@test102 ~]# cat -n /etc/gitlab/gitlab.rb |grep smtp
   559  ###! Docs: https://docs.gitlab.com/omnibus/settings/smtp.html
   560  ###! **Use smtp instead of sendmail/postfix.**
   562  # gitlab_rails['smtp_enable'] = true
   563  # gitlab_rails['smtp_address'] = "smtp.server"
   564  # gitlab_rails['smtp_port'] = 465
   565  # gitlab_rails['smtp_user_name'] = "smtp user"
   566  # gitlab_rails['smtp_password'] = "smtp password"
   567  # gitlab_rails['smtp_domain'] = "example.com"
   568  # gitlab_rails['smtp_authentication'] = "login"
   569  # gitlab_rails['smtp_enable_starttls_auto'] = true
   570  # gitlab_rails['smtp_tls'] = false
   574  # gitlab_rails['smtp_openssl_verify_mode'] = 'none'
   576  # gitlab_rails['smtp_ca_path'] = "/etc/ssl/certs"
   577  # gitlab_rails['smtp_ca_file'] = "/etc/ssl/certs/ca-certificates.crt"
[root@test102 ~]#

此外,也能夠修改郵件的默認發送地址、顯示名稱等信息。

[root@test102 ~]# cat -n /etc/gitlab/gitlab.rb |grep gitlab_email
    60  # gitlab_rails['gitlab_email_enabled'] = true
    61  # gitlab_rails['gitlab_email_from'] = 'example@example.com'
    62  # gitlab_rails['gitlab_email_display_name'] = 'Example'
    63  # gitlab_rails['gitlab_email_reply_to'] = 'noreply@example.com'
    64  # gitlab_rails['gitlab_email_subject_suffix'] = ''
    65  # gitlab_rails['gitlab_email_smime_enabled'] = false
    66  # gitlab_rails['gitlab_email_smime_key_file'] = '/etc/gitlab/ssl/gitlab_smime.key'
    67  # gitlab_rails['gitlab_email_smime_cert_file'] = '/etc/gitlab/ssl/gitlab_smime.crt'
[root@test102 ~]#

irb(main):003:0> exit
[root@test102 ~]#

3.3 禁用建立組權限

GitLab默認全部的註冊用戶均可以建立組,在實際使用中,一般只會給指定的少部分用戶相關權限。 將/etc/gitlab/gitlab.rb中的gitlab_rails['gitlab_default_can_create_group']參數設爲false,而後重載配置便可。

[root@test102 ~]# cat -n /etc/gitlab/gitlab.rb |grep "create_group"
    70  # gitlab_rails['gitlab_default_can_create_group'] = true
[root@test102 ~]#

3.4 集成OpenLDAP

設置/etc/gitlab/gitlab.rb文件中關於LDAP的內容,並重載配置,而後經過「gitlab-rake gitlab:ldap:check 」命令驗證是不是否能正常獲取用戶列表,最後重啓gitlab服務。

[root@test102 ~]# cat -n /etc/gitlab/gitlab.rb |grep "LDAP Settings"
   296  ### LDAP Settings
[root@test102 ~]#

3.5 GitLab我的中文界面

登陸後,點擊右上角用戶頭像---》Settings---》Preferences---》Localization部分的Language項目---》選擇「簡體中文」並保存更改---》刷新頁面。
