02 备份过程记录

Gitlab服务器与备份服务器进行密钥配对，免密使用scp传输Gitlab备份文件

例如：Gitlab server(Gitlab服务器)：181.137.128.32

Bakcup server(远程备份服务器）: 181.137.128.103

在Gitlab服务器上生成密钥对

ssh-keygen -t rsa

拷贝Gitlab上的公钥上传到备份服务器的指定目录（~/.ssh/authorized_keys）:默认为当前用户的.ssh/authorized_keys文件内，为避免权限问题，直接用root账户

# 在gitlab上执行，如果端口不是默认的22，采用scp的方式拷贝gitlab公钥

ssh-copy-id  root@181.137.128.103

创建Gitlab档案备份脚本（本地备份）

#!/bin/bash

# Script Name: auto-backup-gitlabdata.sh

# Functions: auto backup gitlab data

# backup gitlab config

tar -czvf /secret/gitlab/backups/$(date "+etc-gitlab-\%s.tgz") -C / etc/gitlab

# backup gitlab os

#/opt/gitlab/bin/gitlab-rake gitlab:backup:create

# gitlab本地备份路径

LocalBackDir=/var/opt/gitlab/backups

# 备份时间戳

BackupDate=`date +"%F-%T"`

# 备份日志目录

LogDir=$LocalBackDir/log

[ -d $LogDir ] || mkdir -p $LogDir

# 新建日志文件

LogFile=$LocalBackDir/log/backup_${ BackupDate }.log

touch $LogFile

# 追加日志到日志文件

echo "Gitlab auto backup at local server, start at $(date "+%Y-%m-%d %H:%M:%S")" >>  $LogFile

echo "--------------------------------------------------------------------------" >> $LogFile

# 执行gitlab本地备份功能

/opt/gitlab/bin/gitlab-rake gitlab:backup:create

if [ $? -eq 0 ]

then

echo "--------------------------------Success!-------------------------------" >> $LogFile

echo "Gitlab auto backup at local server, end at $(date "+%Y-%m-%d %H:%M:%S")" >> $LogFile

else

  echo "--------------------------------Failed!----------------------------------" >> $LogFile

  echo "Gitlab auto backup at local server failed at $(date "+%Y-%m-%d %H:%M:%S")" >> $LogFile

fi

创建shell定时备份Gitlab档案到远程脚本（远程备份）

#!/bin/bash

# Script Name: auto-backup-gitlabdata-to-remote.sh

# Gitlab 档案备份路径（本地备份路径）

LocalBackDir=/var/opt/gitlab/backups

# Backup server 存储路径（远程备份路径）

RemoteBackDir=/data/software-data-backup/gitlab

# 远程备份使用用户及端口

RemoteUser=root

RemotePort=22

# 备份服务器IP

RemoteIP=181.137.128.103

# 备份时间戳

BackupDate=` date "+%F-%T" `

# 备份日志文件

LogFile=$LocalBackDir/auto-backup-gitlabdata.log

# 查找本地备份目录下一天以内且后缀为.tar的Gitlab备份文件

Backfile_Send_To_Remote=$(find /var/opt/gitlab/backups -type f -mtime -1 -name '\*.tar')

#Backfile\_Send\_To\_Remote=` find $LocalBackDir -type f -mtime -1 -name '\*.tar' `

# 新建备份日志文件

touch $LogFile

# 记录备份日志

echo "${ BackupDate } Gitlab auto backup to remote server." >> $LogFile

echo "--------------------------------------------" >> $LogFile

# 打印每次备份的档案名

echo "The files need send to remote server is: $Backfile\_Send\_To\_Remote" >> $LogFile

# 本地传输Gitlab备份档案到远程

scp -P $RemotePort  $Backfile_Send_To_Remote $RemoteUser@$RemoteIP:$RemoteBackDir

# 备份结果追加到备份日志

if [ $? -eq 0 ]

then

  echo ""

  echo "$ ${ BackupDate } Gitlab Remote Backup Succeed!" >> $LogFile

else

  echo "$ ${ BackupDate } Gitlab Remote Backup Failed!" >> $LogFile

fi

定时执行脚本（crontab）
