定時備份指令碼分享（網站資料和資料庫資料）
阿新 • • 發佈：2018-12-03
1）網站資料備份
將網站資料/var/www/vhost/www.hqsb.com和/var/www/vhost/www.huanqiu.com分別備份到：
/Data/code-backup/www.hqsb.com和/Data/code-backup/www.huanqiu.com下。
[[email protected]_web5 code-backup]# cat web_code_backup.sh #!/bin/bash #備份網站資料 /bin/tar -zvcf /Data/code-backup/www.kevin.com/www.kevin.com_`date +%Y%m%d_%H%M%S`.tar.gz /var/www/vhosts/www.kevin.com /bin/tar -zvcf /Data/code-backup/www.grace.com/www.grace.com_`date +%Y%m%d_%H%M%S`.tar.gz /var/www/vhosts/www.grace.com #刪除一週之前的備份檔案 find /Data/code-backup/www.kevin.com -type f -mtime +7 -exec rm -f {} \; find /Data/code-backup/www.grace.com -type f -mtime +7 -exec rm -f {} \; [[email protected]_web5 ~]# crontab -l #每天凌晨5點備份網站資料 0 5 * * * /bin/bash -x /Data/code-backup/web_code_backup.sh > /dev/null 2>&1 備份後的效果如下： [[email protected]_web5 ~]# ls /Data/code-backup/www.kevin.com/ www.kevin.com_20170322_174328.tar.gz [[email protected]_web5 ~]# ls /Data/code-backup/www.grace.com/ www.grace.com_20170322_174409.tar.gz
2）資料庫備份（自動刪除10天前的備份檔案）
資料庫服務使用的是阿里雲的mysql，遠端進行定時的全量備份，備份到本地，以防萬一。mysql資料庫遠端備份的資料最好打包壓縮
[[email protected] crontab]# pwd /Data/Mysql_Bakup/crontab [[email protected] crontab]# cat backup_db_wangshibo.sh #!/bin/bash MYSQL="/usr/bin/mysql" MYSQLDUMP="/usr/bin/mysqldump" BACKUP_DIR="/Data/Mysql_Bakup" #DB_SOCKET="/var/lib/mysql/mysql.sock" DB_hostname="110.120.11.9" DBNAME="wangshibo" DB_USER="db_wangshibo" DB_PASS="mhxzk3rfzh" TIME=`date +%Y%m%d%H%M%S` LOCK_FILE="${BACKUP_DIR}/lock_file.tmp" BKUP_LOG="/Data/Mysql_Backup/${TIME}_bkup.log" DEL_BAK=`date -d '10 days ago' '+%Y%m%d'` ##To judge lock_file if [[ -f $LOCK_FILE ]];then exit 255 else echo $$ > $LOCK_FILE fi ##dump databases## echo ${TIME} >> ${BKUP_LOG} echo "=======Start Bakup============" >>${BKUP_LOG} #${MYSQLDUMP} -h ${DB_hostname} -u${DB_USER} -p${DB_PASS} --databases ${DBNAME} | gzip -9 > ${BACKUP_DIR}/${TIME}.${DBNAME}.gz ${MYSQLDUMP} -h ${DB_hostname} -u${DB_USER} -p${DB_PASS} --databases ${DBNAME} |gzip -9 > ${BACKUP_DIR}/${TIME}.${DBNAME}.gz echo "=======Finished Bakup============" >>${BKUP_LOG} /bin/rm -f ${LOCK_FILE} ##del back 10 days before## /bin/rm -f ${BACKUP_DIR}/${DEL_BAK}*.gz
定時進行備份
[[email protected] Mysql_Bakup]# crontab -l
10 0,6,12,18 * * * /bin/bash /Data/Mysql_Bakup/crontab/backup_db_wangshibo.sh >/dev/null 2>&1指令碼執行後的備份效果如下
[[email protected] crontab]# cd /Data/Mysql_Bakup
[[email protected] Mysql_Bakup]# ls
20161202061001.wangshibo.gz同步線上資料庫到beta環境資料庫（覆蓋beta資料庫）：
將上面定時備份的資料包拷貝到beta機器上，然後解壓，登陸mysql，source命令進行手動覆蓋。
