Automatic backup of MongoDB database with shell script

First, create a MongoDB backup directory

Used to store data

mkdir -p /data/mongodb_bak/mongodb_bak_now

mkdir-p /data/mongodb_bak/mongodb_bak_list

Ii. Creating a MongoDB database backup script

#!/bin/bash
#

Dump=/usr/local/mongodb/bin/mongodump #mongodump命令路Path

Out_dir=/data/mongodb_bak/mongodb_bak_now #临时备份目录

Tar_dir=/data/mongodb_bak/mongodb_bak_list #备份存放路径

Date= ' Date +%y_%m_%d ' #获取当前系统时间

Db_user=myadmin #数据库账号

db_pass=****** #数据库密码

DAYS=20#DAYS=20代表删除20天前的备份，即只保留近20天的备份

tar_bak= "mongodb_bak_$date.tar.gz" #最终保存的数据库备份文件

CD $OUT _dir

RM-RF $OUT _dir/*

Mkdir-p $OUT _dir/$DATE

$DUMP-H 127.0.0.1:27017-u $DB _user-p $DB _pass--authenticationdatabase "admin"-o $OUT _dir/$DATE #备份全部数据库

TAR-ZCVF $TAR _dir/$TAR _bak $out_dir/$DATE #压缩为. tar.gz format

Find $TAR _dir/-mtime + $DAYS-delete #删除20天前的备份文件

Exit

Execute permissions for scripts

[Email protected] mongodb_bak]# chmod +x mongodb_bak.sh

Third, testing

Run the script

[email protected] mongodb_bak]# sh +x mongodb_bak.sh

View in Directory

To restore data:

[Email protected] mongodb_bak]# mongorestore-h 127.0.0.1:27017-d cara2/data/mongodb_bak/mongodb_bak_now/2018_07_25 /cara

Enter the database to view:

The data is OK, it means the backup is okay!

Iv. Adding timed tasks

[Email protected] ~]# CRONTAB-E

* * * * */data/mongodb_bak/mongodb_bak.sh#每天18：00执行MongoDB数据库备份脚本
