準(zhǔn)備工作：
創(chuàng)建mysql備份賬號：
GRANT SELECT, RELOAD, PROCESS, SUPER, LOCK TABLES, REPLICATION CLIENT ON *.* TO 'backup'@'localhost' IDENTIFIED BY 'XXX';
FLUSH PRIVILEGES
1翎卓， 全備腳本（backup.sh）
#!/usr/bin/env sh
#
# full backup
################################################################################
################################################################################
BINLOG_HOME=/export/mysql/logs

# make one backup
innobackupex --defaults-file=/etc/mysql/my.cnf --user='backup' \
--password='XXX' --slave-info? --safe-slave-backup \
--compress --compress-threads=4 $BACKUP_DEST
2, 備份log ( backup_log.py）
#!/usr/bin/python
#
# log backup
import os
import os.path
import shutil
import time,? datetime
import re
binlog_home = '/export/mysql/logs/'
backup_home = '/export/mysql_backup/log'
basename = 'mysql-bin.[0-9]'
def copyFiles(sourceDir, targetDir):
if not os.access(sourceDir, os.F_OK):
print '%s does not exist' %(sourceDir)
return
if sourceDir.find(".svn") > 0:
return
for file in os.listdir(sourceDir):
sourceFile = os.path.join(sourceDir, file)
targetFile = os.path.join(targetDir, file)
if os.path.isfile(sourceFile) and re.compile(basename).match(file):
if not os.path.exists(targetDir):
os.makedirs(targetDir)
if not os.path.exists(targetFile) or (os.path.exists(targetFile) and (os.path.getsize(targetFile) != os.path.getsize(sourceFile))):
open(targetFile, "wb").write(open(sourceFile, "rb").read())
if? __name__ =="__main__":
print "Start binlog Copying..."
copyFiles(binlog_home, backup_home)
print "End Copying!"
3桩砰，清理歷史文件（cleanoldfile.sh）
#!/bin/sh
#
#? clean up history backup data/log files
echo "begin cleaning..."
find /export/mysql_backup/full -type d -ctime +10 | xargs rm -rf
find /export/mysql_backup/log -type f -ctime +7 | xargs rm -rf
echo "end cleaning!"
4，crontab設(shè)置：
0 1 * * * /export/mysql_backup/cleanoldfile.sh
0 2 * * * /export/mysql_backup/backup.sh
*/30 * * * * /export/mysql_backup/backup_log.py
