数据库备份到天翼云对象存储OBS
https://blog.csdn.net/qq_34631220/article/details/135755894
1、获得所有数据库
bash
#!/bin/sh
HOSTNAME="ip" #数据库信息
PORT="3306"
USERNAME="root"
PASSWORD=""
DBNAME="yusuan" #数据库名称
# select_sql="select * from dade"
# 获得所有数据库
select_sql="show databases"
data=$(mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${select_sql}")
for list in ${data}
do
if [ "$list" != "Database" ] && [ "$list" != "information_schema" ] && [ "$list" != "mysql" ] && [ "$list" != "performance_schema" ] && [ "$list" != "sys" ];then
if [ "$list" == "yusuan" ]; then
echo "数据库66666----${list}"
else
echo "数据库----${list}"
fi
fi
done
2.单库表级备份
bash
#!/bin/sh
# 获得时间date "+%Y-%m-%d %H:%M:%S"
mkdirYmd=$(date +%Y%m%d)
ymd=$(date +%Y%m%d-%H:%M:%S)
# 判断目录是否存在,不存在创建,压缩存放目录
[ -d /obsfs/obsfs_CentOS7.6_amd64/zip ] || mkdir -p /obsfs/obsfs_CentOS7.6_amd64/zip
HOSTNAME="ip" #数据库信息
PORT="3306"
USERNAME="root"
PASSWORD=""
DBNAME="yusuan" #数据库名称
# select_sql="select * from dade"
# 获得所有数据库
select_sql="show databases"
data=$(mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${select_sql}")
for list in ${data}
do
if [ "$list" != "Database" ] && [ "$list" != "information_schema" ] && [ "$list" != "mysql" ] && [ "$list" != "performance_schema" ] && [ "$list" != "sys" ];then
if [ "$list" == "yusuan" ]; then
echo "数据库66666----${list}"
# 判断目录是否存在,不存在创建,日期+库名创建目录
[ -d /obsfs/obsfs_CentOS7.6_amd64/cdj-file/mysql/${mkdirYmd}/${list} ] || mkdir -p /obsfs/obsfs_CentOS7.6_amd64/cdj-file/mysql/${mkdirYmd}/${list}
# 整库备份
# mysqldump -h${HOSTNAME} -u${USERNAME} -p${PASSWORD} --databases $list >/obsfs/obsfs_CentOS7.6_amd64/sql/${list}.sql
# 按库单表备份
tables_sql="show tables"
Tab=$(mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${list} -e "${tables_sql}")
for it in ${Tab}
do
if [ "$it" != "Tables_in_yusuan" ];then
echo "表-----${it}"
# 单表备份
mysqldump -h${HOSTNAME} -u${USERNAME} -p${PASSWORD} --databases ${list} --tables ${it} > /obsfs/obsfs_CentOS7.6_amd64/sql/${it}_${ymd}.sql
# 单表压缩
zip -r /obsfs/obsfs_CentOS7.6_amd64/zip/${it}_${ymd}.zip /obsfs/obsfs_CentOS7.6_amd64/sql/${it}_${ymd}.sql
# 复制到天翼云对象存储目录OBS(并行文件系统),备份
cp /obsfs/obsfs_CentOS7.6_amd64/zip/${it}_${ymd}.zip /obsfs/obsfs_CentOS7.6_amd64/cdj-file/mysql/${mkdirYmd}/${list}
# 删除两个原文件
rm -rf /obsfs/obsfs_CentOS7.6_amd64/sql/${it}_${ymd}.sql;
rm -rf /obsfs/obsfs_CentOS7.6_amd64/zip/${it}_${ymd}.zip;
fi
done
else
echo "数据库----${list}"
fi
fi
done
3、备份所有库(表级)
bash
#!/bin/sh
# 获得时间date "+%Y-%m-%d %H:%M:%S"
mkdirYmd=$(date +%Y%m%d)
ymd=$(date +%Y%m%d-%H:%M:%S)
# 判断目录是否存在,不存在创建,压缩存放目录
[ -d /obsfs/obsfs_CentOS7.6_amd64/zip ] || mkdir -p /obsfs/obsfs_CentOS7.6_amd64/zip
HOSTNAME="ip" #数据库信息
PORT="3306"
USERNAME="root"
PASSWORD=""
DBNAME="yusuan" #数据库名称
# select_sql="select * from dade"
# 获得所有数据库
select_sql="show databases"
data=$(mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${select_sql}")
for list in ${data}
do
if [ "$list" != "Database" ] && [ "$list" != "information_schema" ] && [ "$list" != "mysql" ] && [ "$list" != "performance_schema" ] && [ "$list" != "sys" ];then
echo "数据库----${list}"
# 判断目录是否存在,不存在创建,日期+库名创建目录
[ -d /obsfs/obsfs_CentOS7.6_amd64/cdj-file/mysql/${mkdirYmd}/${list} ] || mkdir -p /obsfs/obsfs_CentOS7.6_amd64/cdj-file/mysql/${mkdirYmd}/${list}
# 整库备份
# mysqldump -h${HOSTNAME} -u${USERNAME} -p${PASSWORD} --databases $list >/obsfs/obsfs_CentOS7.6_amd64/sql/${list}.sql
# 按库单表备份
tables_sql="show tables"
Tab=$(mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD} ${list} -e "${tables_sql}")
for it in ${Tab}
do
if [ "$it" != "Tables_in_yusuan" ];then
echo "库:${list}---表:${it}"
# 单表备份
mysqldump -h${HOSTNAME} -u${USERNAME} -p${PASSWORD} --databases ${list} --tables ${it} > /obsfs/obsfs_CentOS7.6_amd64/sql/${it}_${ymd}.sql
# 单表压缩
zip -r /obsfs/obsfs_CentOS7.6_amd64/zip/${it}_${ymd}.zip /obsfs/obsfs_CentOS7.6_amd64/sql/${it}_${ymd}.sql
# 复制到天翼云对象存储目录OBS(并行文件系统),备份
cp /obsfs/obsfs_CentOS7.6_amd64/zip/${it}_${ymd}.zip /obsfs/obsfs_CentOS7.6_amd64/cdj-file/mysql/${mkdirYmd}/${list}
# 删除两个原文件
rm -rf /obsfs/obsfs_CentOS7.6_amd64/sql/${it}_${ymd}.sql;
rm -rf /obsfs/obsfs_CentOS7.6_amd64/zip/${it}_${ymd}.zip;
