Ubuntu服务器上的MySQL自动备份

Question

After months of trying to get this to happen I found a shell script that will get the job done.

Heres the code I'm working with

#!/bin/bash
### MySQL Server Login Info ###
MUSER="root"
MPASS="MYSQL-ROOT-PASSWORD"
MHOST="localhost"
MYSQL="$(which mysql)"
MYSQLDUMP="$(which mysqldump)"
BAK="/backup/mysql"
GZIP="$(which gzip)"
### FTP SERVER Login info ###
FTPU="FTP-SERVER-USER-NAME"
FTPP="FTP-SERVER-PASSWORD"
FTPS="FTP-SERVER-IP-ADDRESS"
NOW=$(date +"%d-%m-%Y")

### See comments below ###
### [ ! -d $BAK ] && mkdir -p $BAK || /bin/rm -f $BAK/* ###
[ ! -d "$BAK" ] && mkdir -p "$BAK"

DBS="$($MYSQL -u $MUSER -h $MHOST -p$MPASS -Bse 'show databases')"
for db in $DBS
do
 FILE=$BAK/$db.$NOW-$(date +"%T").gz
 $MYSQLDUMP -u $MUSER -h $MHOST -p$MPASS $db | $GZIP -9 > $FILE
done

lftp -u $FTPU,$FTPP -e "mkdir /mysql/$NOW;cd /mysql/$NOW; mput /backup/mysql/*; quit" $FTPS

Everything is running great, however there are a few things I'd like to fix but am clueless when it comes to shell scripts. I'm not asking anyone to write it. Just some pointers. First of all the /backup/mysql directory on my server stacks the files everytime it backs up. Not to big of a deal. But after a year of nightly backups it might get a little full. So id like it to clear that directory after uploading. Also I don't want to overload my hosting service with files so id like it to clear the remote servers dir before uploading. Lastly I would like it to upload to a subdirectory on the remote server such as /mysql

Why reinvent the wheel? You can just use Debian 's automysqlbackup package (should be available on Ubuntu as well).

As for cleaning old files the following command might be of help:

find /mysql -type f -mtime +16 -delete

Uploading to remote server can be done using scp (1) command;
To avoid password prompt read about SSH public key authentication

Take a look at Backup , it allows you to model your backup jobs using a Ruby DSL, very powerful.

Support multiple DBs and most popular online storages, and lots of cool features.
