Gitlab安装

GitLab简介
GitLab 是一个用于仓库管理系统的开源项目。使用Git作为代码管理工具,并在此基础上搭建起来的web服务。可通过Web界面进行访问公开的或者私人项目。它拥有与Github类似的功能,能够浏览源代码,管理权限和注释。可以管理团队对仓库的访问,它非常易于浏览提交过的版本并提供一个文件历史库。团队成员可以利用内置的简单聊天程序(Wall)进行交流。它还提供一个代码片段收集功能可以轻松实现代码复用。
常用的网站:
官网:https://about.gitlab.com/
国内镜像:https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/
安装环境:
1、CentOS 6或者7
2、2G内存(实验)生产(至少4G)
3、安装包:gitlab-ce-10.2.2-ce
4、禁用防火墙,关闭selinux

8. Gitlab备份与恢复

对gitlab进行备份将会创建一个包含所有库和附件的归档文件。对备份的恢复只能恢复到与备份时的gitlab相同的

版本。将gitlab迁移到另一台服务器上的最佳方法就是通过备份和还原。

gitlab提供了一个简单的命令行来备份整个gitlab,并且能灵活的满足需求。

备份文件将保存在配置文件中定义的backup_path中,文件名为TIMESTAMP_gitlab_backup.tar,TIMESTAMP为备份时的时间戳。TIMESTAMP的格式为:EPOCH_YYYY_MM_DD_Gitlab‐version。如果自定义备份目录需要赋予git权限。

01. 备份

#配置文件中加入
[root@git ~/git_data]# vim /etc/gitlab/gitlab.rb
gitlab_rails['manage_backup_path'] = true #开启备份
gitlab_rails['backup_path'] = '/data/backup/gitlab' #备份目录
gitlab_rails['backup_archive_permissions'] = 0644 #生成的备份文件权限
gitlab_rails['backup_keep_time'] = 604800 #备份保留的时间(以秒为单位,这是七天默认值)
[root@git ~/git_data]# mkdir /data/backup/gitlab
[root@git ~/git_data]# chown ‐R git.git /data/backup/gitlab

#完成后执行下面命令进行生效

[root@git ~/git_data]# gitlab‐ctl reconfigure

#手动备份
[root@git ~/git_data]# gitlab-rake gitlab:backup:create

#检查结果
[root@git ~/git_data]# ll /data/opt/gitlab/
total 112
-rw-r--r-- 1 git git 112640 Nov 17 18:22 1573986174_2019_11_17_10.2.2_gitlab_backup.tar

自动备份需要写一个备份脚本及定时任务

#Gitlab恢复操作

Gitlab只能还原到与备份文件相同的gitlab版本。

#误删除数据

[root@git ~/git_test]# rm -rf ./

#提交推送

[root@git ~/git_test]# git commit -am "add 123 "
[master 35ef629] add 123
3 files changed, 8 deletions(-)
