创建docker 容器，映射到home/mysql 目录下
sudo docker run -d -v /home/mysql:/var/lib/mysql -p 3306:3306 --name mysql -e MYSQL_ROOT_PASSWORD="h123456" mysql:5.6
进入mysql
docker exec -it mysql bash
mysql -uroot -p
mysql 创建用户
create user 'hyp'@‘localhost’ IDENTIFIED By ‘123456’；
给用户授权(blog_Core库的所有表)
GRANT SELECT, INSERT,CREATE ON Blog_Core.* TO 'hyp'@‘localhost’;
Mysql 自动备份
因为MySQL 映射在/home/mysql 文件夹下面，所以在 mysql 文件夹下面创建目录
mkdir -p /data/mysqlbak/data
mkdir -p /data/mysqlbak/scripts
mkdir -p /data/mysqlbak/logs
创建备份脚本
cd /home/mysql/data/mysqlbak/scripts
vim backup.sh
# !/bin/bash
# 备份目录
BACKUP_ROOT=/home/mysql/data/mysqlbak
BACKUP_FILEDIR=$BACKUP_ROOT/data
# 当前日期
DATE=$(date +%y%m%d)
###### 备份 #####
# 查询所有数据库
# -uroot -ph123456
DATABASES=$(mysql -uroot -ph123456 - e "show databases" | grep -Ev "Database|sys|information_schema|performance_schema|mysql")
#循环数据库备份
for db in $DATABASES
do echo
echo ----------------$BACKUP_FILEDIR/${db}_$DATE.sql.gz BEGIN ----------------------
mysqldump -uroot -ph123456 --default-character-set=utf8 -q --lock-all-tables --flush-logs -E -R --triggers -B ${db} | gzip > $BACKUP_FILEDIR/${db}_$DATE.sql.gz
echo -------------------$BACKUP_FILEDIR/${db}_$DATE.sql.gz COMPLETE -----
echo
done
echo "done"
创建删除脚本（七天前的备份数据）
vi backup_clean.sh
#!/bin/bash
echo ----------CLEAN BEGIN----------
find /home/mysql/data/mysqlbak/data -mtime +7 -name "*.gz" -exec rm -rf {} \;
echo ----------CLEAN COMPLETE----------
设置脚本执行权限
chmod 777 backup.sh
chmod 777 backup_clean.sh
创建备份操作的定时任务
crontab -e
将下面命令加入进去
## 凌晨2点备份
00 2 * * * /home/mysql/data/mysqlbak/scripts/backup.sh > /home/mysql/data/mysqlbak/logs/backup.log 2>&1
## 凌晨1点清除
00 1 * * * /home/mysq/data/mysqlbak/scripts/backup_clean.sh > /home/mysql/data/mysqlbak/logs/backup_full_clean.log 2>&1
查看定时任务
crontab -l
