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.rbgitlab_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="root@10.10.111.223"
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>&1GItlab只能还原到与备份文件相同的gitlab版本。
