本地資料庫mysql，有多個數據庫要備份到遠端伺服器上，遠端伺服器提供vsftp服務

1 - 建立一個shell指令碼，寫入以下內容並儲存

vi.mysql_back.sh

寫入

#!/bin/bash

BIN_DIR="/usr/bin"
BACKUP_DIR="/var/mysql_dump/data"
DATE=`date +%Y%m%d`
mkdir -p $BACKUP_DIR

MYSQL=mysql
HOST="10.XXX.XX.XX"
USER="user"
PASSWORD="password"




# 獲取本地伺服器IP地址

local_ip=$(ifconfig | grep "inet addr" | grep -v 127.0.0.1 | awk '{print $2}' | awk -F ':' '{print $2}')




# 檢視mysql裡面所有資料庫名

command="show databases"
declare DBS=`$MYSQL -h${HOST} -u${USER} -p${PASSWORD} -e "${command}" --skip-column-name`
for DB_NAME in $DBS
do
        if [ "$DB_NAME" != "information_schema" ] && [ "$DB_NAME" != "mysql" ] && [ "$DB_NAME" != "performance_schema" ] && [ "$DB_NAME" != "tower_debug21" ]
        then
        #echo "$DB_NAME"

        # mysqldump出每個資料庫的備份，並壓縮
        $BIN_DIR/mysqldump --opt -u$USER -p$PASSWORD $DB_NAME | gzip > $BACKUP_DIR/$DB_NAME.dump_$DATE.sql.gz
        fi
done




# 上傳到遠端ftp 

ftp -n<<!
open 10.XXX.XX.XXX    
user ftpuser ******           
binary
hash
cd backups/database/$local_ip/
lcd $BACKUP_DIR                     
prompt
mput *.sql.gz

close
bye
!

rm -rf $BACKUP_DIR/*
 

2 - 修改屬性為可執行

chmod 755 mysql_back.sh

3 - crond定時任務每天00：00：00定時執行

0 0 * * * /var/mysql_dump/mysql_back.sh > /dev/null 2>&1
