此方法不是傳統的導出數據，而是直接從mysql的數據目錄對數據庫進行壓縮、備份。同時還會將所備份數據傳到你的遠端FTP備份服務器上。恢復時只需將要恢復的數據解壓回mysql數據目錄並重啓mysql服務即可。因此你必須要有服務器的root權限。
首先，進入/usr/sbin目錄下，用root權限新建一個文件backupmysql，代碼如下：

mysqldbpath="/var/lib/mysql" #Change it to your mysql datas path
mysqldbname=("aa" "bb" "cc") #Change it to your every mysql databases' name you want to backup
dbbackuppath="/home/databasebackup" #Change it to your local mysql backup path
backupftpserver="192.168.0.1" #Change it to the IP address of your remote FTP backup server

cd $dbbackuppath
mkdir $filename
cd $mysqldbpath
for i in ${mysqldbname[*]}
do
tar zcvf $dbbackuppath/$filename/$i.tar.gz $i
done

rmdir $oldfilename

然後根據藍色的注釋修改下前面的變量或語句。為了照顧某些英文不好的，我再用中文說一下：把變量mysqldbpath的值修改為你的mysql數據目錄；把變量mysqldbname的值修改為你每個需要備份的數據庫名；把變量dbbackuppath的值修改為你本地備份mysql數據庫的目錄；把變量backupftpserver的值修改為你想要上傳備份的遠端FTP服務器IP；把變量ftpusername的值修改為遠端FTP服務器用戶名；把變量ftppassword的值修改為遠端FTP服務器密碼；把變量remotedbbackuppath的值修改為遠端FTP服務器的備份路徑（注意格式要按照原有樣例的格式）然後根據你服務器的系統和mysql、apache的安裝情況修改下「/etc/init.d/apache stop」、「/etc/init.d/mysql stop」、「/etc/init.d/mysql start」、「/etc/init.d/apache start」這四個語句，就是改為你服務器上關閉、開啓mysql、apache的命令即可，如果你服務器上關閉、開啓mysql、apache的命令與之相同則不用修改。
然後保存該文件，並賦予755權限，所屬用戶和用戶組均設為root。
以後只要使用root權限執行/usr/sbin/backupmysql就會實現mysql數據庫的備份並上傳到遠端FTP服務器上。
如果需要每天自動備份的話，只需將其加入到cron裡面即可~~
