[root@master]# cat auto_mysql_masterbak.sh

#!/bin/bash
#Author Danrtsey
#function: 主库备份所有库,并记录master status,用于做主从同步恢复时使用
BACKUP_FOLDERNAME=/data/masterbak
DB_USERNAME="root"
DB_PASSWORD="密码"

LOG_FILE=${BACKUPFOLDERNAME}/mysqllogsdate +%F.log
DATA_FILE=${BACKUP_FOLDERNAME}/mysqlbackupdate +%F.sql.gz

MYSQL_CMD="/bin/mysql -u$DB_USERNAME -p$DB_PASSWORD"
MYSQL_DUMP="/bin/mysqldump --set-gtid-purged=off -u$DB_USERNAME -p$DB_PASSWORD -A -B --flush-logs --single-transaction -e"

#锁表--全库备份--查看主库状态并记录--解琐表
$MYSQL_CMD -e "flush tables with read lock;"
echo "-----show master status result-----" >>$LOG_FILE
$MYSQL_CMD -e "show master status;" >>$LOG_FILE
${MYSQL_DUMP} | gzip > $DATA_FILE
$MYSQL_CMD -e "unlock tables;"
#保留10份备份文件
find ${BACKUP_FOLDERNAME} -mtime +10 -name ".sql.gz" -exec rm -rf {} \;
find ${BACKUP_FOLDERNAME} -mtime +10 -name ".log" -exec rm -rf {} \;
4、从库同步脚本

[root@slave]# cat auto_mysql_slavebak.sh
#!/bin/bash
#Author Danrtsey
#function: 从库使用主库/data/masterbak的备份
#查看/data/masterbak下面的mysqllogs记录的主库master status信息
#从库同步时填写相关信息，实现从库随时同步使用

#注意更改MASTER_LOG_FILE对应的数值及MASTER_LOG_POS的数值，举例如下
#MASTER_LOG_FILE=‘mysql-bin.000002‘,
#MASTER_LOG_POS=342;

BACKUP_FOLDERNAME=/data/slavebak
DB_USERNAME="root"
DB_PASSWORD="密码"

LOG_FILE=${BACKUPFOLDERNAME}/mysqllogsdate +%F.log
DATA_FILE=${BACKUP_FOLDERNAME}/mysqlbackupdate +%F.sql.gz

MYSQL_CMD="/bin/mysql -u$DB_USERNAME -p$DB_PASSWORD"

#recover
cd ${BACKUP_FOLDERNAME}
gzip -d mysqlbackupdate +%F.sql.gz
$MYSQL_CMD < mysqlbackupdate +%F.sql

$MYSQL_CMD -e "stop slave;"
#config slave
$MYSQL_CMD -e "CHANGE MASTER TO MASTER_HOST=‘192.168.8.129‘,MASTER_PORT=3306,MASTER_USER=‘slave‘,MASTER_PASSWORD=‘密码‘,MASTER_LOG_FILE=‘mysql-bin.000002‘,MASTER_LOG_POS=342;"

$MYSQL_CMD -e "start slave;"
$MYSQL_CMD -e "show slave status\G"|egrep "IO_Running|SQL_Running" >$LOG_FILE
cat $LOG_FILE

从库同步时，查看日志显示有两个yes表示从库同步成功
