数据库服务使用的是阿里云的mysql,远程进行定时的全量备份,备份到本地,以防万一。mysql数据库远程备份的数据最好打包压缩:
[root@huanqiuPC crontab]# pwd
/Data/Mysql_Bakup/crontab
[root@huanqiuPC 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
定时进行备份
[root@huanqiuPC Mysql_Bakup]# crontab -l
10 0,6,12,18 * * * /bin/bash /Data/Mysql_Bakup/crontab/backup_db_wangshibo.sh >/dev/null 2>&1
[root@huanqiuPC crontab]# cd /Data/Mysql_Bakup
[root@huanqiuPC Mysql_Bakup]# ls
20161202061001.wangshibo.gz
同步线上数据库到beta环境数据库(覆盖beta数据库):
将上面定时备份的数据包拷贝到beta机器上,然后解压,登陆mysql,source命令进行手动覆盖。
