Hi@ all!

Ich suche für mein Abschlussprojekt zum Fachinformatiker ein cron Script o.ä. was automatisch jeden Tag ein Backup der MySQL Datenbank macht und es auf einem Netzlaufwerk sichert (ist bereits gemountet unter /mnt/sqlbackup). Zusätzlich solltr es auch alte Backups löschen z.B. alle die älter als 30 Tage sind.
Und das script sollte falls ein fehler vorliegt eine mail an einen mail empfänger schicken können.
Wäre echt sehr nett wenn sich jemand mit meinem Problem beschäftigen könnte!

PS: habe Suse 9.1 im Einsatz

thx im Voraus

Hier wird dir erklärt wie du Dateien findest die ein bestimtes Alter überschritten haben:
http://linuxwiki.de/find?highlight=%28find%29
Hier wird dir das Cron Prinzip erklärt:
http://linuxwiki.de/cron?highlight=%28cron%29
So macht man irgenwie Mysqldumps
http://gd.tuwien.ac.at/linuxcommand.org/man_pages/mysqldump1.html

Jetzt musst du es nur noch zusammenfügen, den mysqldump erstellen und fertig ist das Script. Und falls du ein bisschen suchst bei google dann findest du vielleicht ein fertiges Script.

ok danke werd ich gleich mal versuchen wenn ich folgendes problem gelöst habe. Habe mir von http://sourceforge.net/project/showfiles.php?group_id=101066 das automysql backup script gezogen und alle einstellungen gemacht. wenn ich das script nun mit:

"sh automysqlbackup-2.sh.2.2"

ausführen will kommt der Fehler:

Wodran kann das liegen? in z.B. zeile 26 steht doch überhaupt nichts?



@ devilz

Das projek umfasst mehr das ist nur nen bruchteil davon, bin nur mit meinem wissen am ende und brauch Hilfe / unterstützung von jemanden der sich halt besser aus kennt ...

# ================================================== ==========
# === ADVANCED OPTIONS ( Read the doc's below for details )===
#================================================= ============

# List of DBBNAMES for Monthly Backups.
MDBNAMES="mysql $DBNAMES"

# List of DBNAMES to EXLUCDE if DBNAMES are set to all (must be in " quotes)
DBEXCLUDE=""

# Include CREATE DATABASE in backup?

# Separate backup directory and file for each DB? (yes or no)
SEPDIR=yes

# Which day do you want weekly backups? (1 to 7 where 1 is Monday)
DOWEEKLY=6

# Choose Compression type. (gzip or bzip2)
COMP=gzip

# Command to run before backups (uncomment to use)
#PREBACKUP="/etc/mysql-backup-pre"

# Command run after backups (uncomment to use)
#POSTBACKUP="/etc/mysql-backup-post"

#================================================= ====================
# Options documantation
#================================================= ====================
# Set USERNAME and PASSWORD of a user that has at least SELECT permission
# to ALL databases.
#
# Set the DBHOST option to the server you wish to backup, leave the
# default to backup "this server".(to backup multiple servers make
# copies of this file and set the options for that server)
#
# Put in the list of DBNAMES(Databases)to be backed up. If you would like
# to backup ALL DBs on the server set DBNAMES="all".(if set to "all" then
# any new DBs will automatically be backed up without needing to modify
# this backup script when a new DB is created).
#
# If the DB you want to backup has a space in the name replace the space
# with a % e.g. "data base" will become "data%base"
# NOTE: Spaces in DB names may not work correctly when SEPDIR=no.
#
# You can change the backup storage location from /backups to anything
# you like by using the BACKUPDIR setting..
#
# The MAILCONTENT and MAILADDR options and pretty self explanitory, use
# these to have the backup log mailed to you at any email address or multiple
# email addresses in a space seperated list.
# (If you set mail content to "log" you will require access to the "mail" program
# on your server. If you set this to "files" you will have to have mutt installed
# on your server. If you set it sto stdout it will log to the screen if run from
# the console or to the cron job owner if run through cron)
#
# MAXATTSIZE sets the largest allowed email attachments total (all backup files) you
# want the script to send. This is the size before it is encoded to be sent as an email
# so if your mail server will allow a maximum mail size of 5MB I would suggest setting
# MAXATTSIZE to be 25% smaller than that so a setting of 4000 would probably be fine.
#
# Finally copy automysqlbackup.sh to anywhere on your server and make sure
# to set executable permission. You can also copy the script to
# /etc/cron.daily to have it execute automatically every night or simply
# place a symlink in /etc/cron.daily to the file if you wish to keep it
# somwhere else.
# NOTE:On Debian copy the file with no extention for it to be run
# by cron e.g just name the file "automysqlbackup"
#
# Thats it..
#
#
# === Advanced options doc's ===
#
# The list of MDBNAMES is the DB's to be backed up only monthly. You should
# always include "mysql" in this list to backup your user/password
# information along with any other DBs that you only feel need to
# be backed up monthly. (if using a hosted server then you should
# probably remove "mysql" as your provider will be backing this up)
# NOTE: If DBNAMES="all" then MDBNAMES has no effect as all DBs will be backed
# up anyway.
#
# If you set DBNAMES="all" you can configure the option DBEXCLUDE. Other
# wise this option will not be used.
# This option can be used if you want to backup all dbs, but you want
# exclude some of them. (eg. a db is to big).
#
# Set CREATE_DATABASE to "yes" (the default) if you want your SQL-Dump to create
# a database with the same name as the original database when restoring.
# Saying "no" here will allow your to specify the database name you want to
# restore your dump into, making a copy of the database by using the dump
# created with automysqlbackup.
# NOTE: Not used if SEPDIR=no
#
# The SEPDIR option allows you to choose to have all DBs backed up to
# a single file (fast restore of entire server in case of crash) or to
# seperate directories for each DB (each DB can be restored seperately
# in case of single DB corruption or loss).
#
# To set the day of the week that you would like the weekly backup to happen
# set the DOWEEKLY setting, this can be a value from 1 to 7 where 1 is Monday,
# The default is 6 which means that weekly backups are done on a Saturday.
#
# COMP is used to choose the copmression used, options are gzip or bzip2.
# bzip2 will produce slightly smaller files but is more processor intensive so
# may take longer to complete.
#
# Use PREBACKUP and POSTBACKUP to specify Per and Post backup commands
# or scripts to perform tasks either before or after the backup process.
#
#
#================================================= ====================
# Backup Rotation..
#================================================= ====================
#
# Daily Backups are rotated weekly..
# Weekly Backups are run by default on Saturday Morning when
# cron.daily scripts are run...Can be changed with DOWEEKLY setting..
# Weekly Backups are rotated on a 5 week cycle..
# Monthly Backups are run on the 1st of the month..
# Monthly Backups are NOT rotated automatically...
# It may be a good idea to copy Monthly backups offline or to another
# server..
#
#================================================= ====================
# Please Note!!
#================================================= ====================
#
# I take no resposibility for any data loss or corruption when using
# this script..
# This script will not help in the event of a hard drive crash. If a
# copy of the backup has not be stored offline or on another PC..
# You should copy your backups offline regularly for best protection.
#
# Happy backing up...
#
#================================================= ====================
# Restoring
#================================================= ====================
# Firstly you will need to uncompress the backup file.
# eg.
# gunzip file.gz (or bunzip2 file.bz2)
#
# Next you will need to use the mysql client to restore the DB from the
# sql file.
# eg.
# mysql --user=username --pass=password --host=dbserver database < /path/file.sql
# or
# mysql --user=username --pass=password --host=dbserver -e "source /path/file.sql" database
#
# NOTE: Make sure you use "<" and not ">" in the above command because
# you are piping the file.sql to mysql and not the other way around.
#
# Lets hope you never have to use this.. :)
#
#================================================= ====================

ich kann das script doch normal mit sh dateiname.sh aufrufen oder mach ich da schon was falsch?

keiner mehr eine idee? kann es sein das irgendwas nicht installiert ist was das script brauch? hatte das selbe problem schon bei anderen scripten dieser art immer kommt command not found :(

DaMutz
26.03.2005, 16:13
hast du passwort und so verändert?
was kommt wenn du date in der Konsole eingibst?
und beim /backup hast du schreibrechte?

probier es doch selber mit dem mysqldump befehl es ist nicht so schwer denke ich. du kannst ja die ideen vom script nehmen und selber ein script basteln das nicht so allgemein gehalten ist, wie dieses hier.

TimoW
26.03.2005, 17:42
so hab mir jetzt nen script gebastelt was mir die Sicherung macht.



#!/bin/sh
#
# Datum Zuweisen
datum=$(date +"%d-%m-%y_%M-%H")
#
# Dump erzeugen

rm $datum.sql


die dump file soll auf einem netzlaufwerk gespeichert werden welches unter /mnt/sicherung gemountet ist. Nur mein problem ist falls das Netzlaufwerk aus irgend nem grund nicht gemountet wird, dann würde er das script im Ordner /mnt/sicherung ablegen. Wie kann ich das verhindern bzw. wie kann ich da ne Kontroloption herein bringen ob sicherung gemountet ist?

danke

Ich hab zwar keine Ahnung von Programmierung, aber "mount" gibt doch die derzeit gemounteten devices aus, einfach mit ner if-schleife rückchecken, if <mountname> ist in output von mount, mach weiter ansonsten mounte mir und mach dann weiter.. Erschiene mir als logische Lösung.

Da ich aber nicht mal weis was cron is und von Programmierung keine Ahnung hab, seid mir nicht böse wenn ich gerade Blödsinn schwafle.

jaja, wenn man sich Scripte zieht, die man nicht versteht :think:

Ich hätte das ja etwas anders angefasst. KISS sollte dir was sagen (Keep it stupid simple)

Warum eigentlich ein gemountetes Laufwerk? Du kannst doch die Dateien auch per FTP übertragen. Und das lässt sich hervorragend scripten. Das kannst du ein ein sogenanntes Here Document packen. ( Info (http://www.unixboard.de/vb3/archive/index.php/t-11399.html))

Und der Rest ist dann nur noch Routine. Für das Löschen der Altdateien würde ich ein kleines Script auf dem Zielserver schreiben.

Geht also alles ohne abgekupferter Scripte.

P.S. Du würdest bei der Prüfung eh wie ein begossener Pudel dastehen, wenn du ein super Script hast, welches du nicht erklären kannst.
