Gitlab 定时备份

要求
1.为了能够备份和恢复，请确保你的系统上安装了Rsync

#Debian/Ubauntu
sudo apt-get install rsync
#  RHEL/Centos
sudo yum install rsync

配置与备份目标机器之间的免密认证

修改gitlab配置文件

vim /etc/gitlab/gitlab.rb

gitlab_rails['manage_backup_path'] = true
gitlab_rails['backup_path'] = "/var/opt/gitlab/backups"    //gitlab默认备份目录，如有需要可更改
gitlab_rails['backup_archive_permissions'] = 0644       //生成的备份文件权限
gitlab_rails['backup_keep_time'] = 604800               //默认备份保留天数为7天（这里是604800秒）

使配置生效

gitlab-ctl reconfigure

创建备份目录并授权

mkdir /var/opt/gitlab/backups && chown -R git.git /var/opt/gitlab/backups/

重新生效Gitlabb配置

gitlab-ctl reconfigure

手动备份：

gitlab-rake gitlab:backup:create

查看备份

ll -sh /opt/gitlab_backups/

编写备份脚本

#!/usr/bin/bash

#获取当前时间
locale_date=`date +%Y-%m-%d.%H.%M.%S`

#远端IP备份主机ip
backup_host=10.10.111.223

#本地备份路径
backup_path=/var/opt/gitlab/backups

#日志路径
backup_log=/var/opt/gitlab/backups/logs/gitlab_back.log

#判断/var/opt/gitlab/backups目录是否存在，否则创建
if [ ! -d ${backup_path} ]; then
        mkdir ${backup_path}
fi

#删除30天之前的备份数据
find ${backup_path} -mtime +5 -name "*" -exec rm -rf {} \;

#CRON=1 环境变量CRON=1的作用是如果没有任何错误发生时， 抑制备份脚本的所有进度输出
#BACKUP=${locale_date}改变backup文件名称 例: 2022-06-15_11:22:52_gitlab_backup.tar

/opt/gitlab/bin/gitlab-backup create BACKUP=${locale_date} CRON=1
if [ $? -eq 0 ];then
        echo "${locale_date} ${backup_path}_gitlab_backup.tar 备份创建成功." >> ${backup_log}
else
        echo "${locale_date} ${backup_path}_gitlab_backup.tar 备份创建失败." >>  ${backup_log}
        exit 1
fi

#拷贝配置文件至本地备份目录/var/opt/gitlab/backups 
cp  /etc/gitlab/gitlab-secrets.json ${backup_path}/${locale_date}_gitlab-secrets.json >> ${backup_log}
cp  /etc/gitlab/gitlab.rb ${backup_path}/${locale_date}_gitlab.rb >> ${backup_log}

# 设置本地备份目录和远程目录
LOCAL_BACKUP_DIR="/var/opt/gitlab/backups/"
REMOTE_SERVER="[email protected]"
REMOTE_DIR="/opt/gitlab_backup/"

# 使用rsync同步目录
rsync -avz --progress $LOCAL_BACKUP_DIR $REMOTE_SERVER:$REMOTE_DIR

GItlab只能还原到与备份文件相同的gitlab版本

​[root@gitlabdev ~]# chmod +x /var/opt/gitlab/gitlab_backup.sh

加入定时任务：

结合crontab实施自动定时备份，比如每天0点、6点、12点、18点各备份一次
crontab -e #添加定时任务

crontab -l #查看已添加定时任务

[root@gitlabdev ~]# crontab -l
0 0,6,12,18 * * * /bin/bash /home/mulan/gitlab-backup.sh > /dev/null 2>&1

GItlab只能还原到与备份文件相同的gitlab版本。

备份恢复脚本（暂未试验）

#!/bin/bash

local_ip=`/sbin/ifconfig -a|grep inet|grep -v 127.0.0.1|grep -v inet6|awk '{print $2}'|tr -d "addr:"`
echo -e "本机IP:${local_ip} \n"

echo -e  "\033[36m发现以下下备份文件:\n \033[0m"
ls  -lt /var/opt/gitlab/backups/*.tar|awk -F '/' '{print $4}'
echo -e "\n\033[36m请输入要恢复的文件或时间节点:\033[0m"
read input

echo "/var/opt/gitlab/backups/${gitlab_backup}_gitlab_backup.tar"
