mysql的本地备份和双机相互备份脚本

先修改脚本进行必要的配置,然后以root用户执行.

  1. 第一执行远程备份时先用 first参数.

  2. 本地备份用local参数

  3. 远程备份不用参数<注意1>

  注意:需要在另一主机上的Mysql用户用添加用户..

  需要配置的地方:

  # define host and mysql password

  REMOTE_HOST="" #远程主机名或IP

  REMOTE_PASSWORD="" #远程主机的mysql中的root@本地主机 密码.

  # define database path

  DB_PATH="/var/lib/mysql" #本地mysql数据库路径

  LOCAL_PASSWORD="" #本地mysql root用户密码

  DB_BACKUP_PATH="/root/db_bk" #本地备份时数据保存的路径

  NO_BACKUP_DB="" 设置本地数据库中不想备份的数据库名,用空格隔开

  直接下载

  #!/bin/sh

  # mysqldump_all.sh

  # this scripts is used to backup MySQL database bettwen tow MySQL SERVER!

  # define host and mysql password

  REMOTE_HOST=""

  REMOTE_PASSWORD=""

  # define database path

  DB_PATH="/var/lib/mysql"

  LOCAL_PASSWORD=""

  DB_BACKUP_PATH="/root/db_bk"

  # define which database no back up, write db anme escap whit space!

  # example;

  # NO_BACKUP_DB="yns test ps_note"

  # this said that if db name is "yns" or "test" or "ps_note", then not backup them!

  NO_BACKUP_DB=""

  # get the database name and process one by one

  echo "Start to Backup...";

  #ls /var/lib/mysql > /tmp/mydb.all

  if [ "$1" != "help" ]; then

  for db in `ls $DB_PATH`; do

  if_backup="1"

  if [ -d $DB_PATH/$db ] ; then

  for noBackDB in $NO_BACKUP_DB ; do

  if ( test "$db" = "$noBackDB" ); then

  #echo -n "...";

  if_backup="";

  fi

  done

  if [ $if_backup ]; then

  echo -n "Crate db [ $db ] on $REMOTE_HOST first!"

  result=`mysqladmin -h $REMOTE_HOST --password=$REMOTE_PASSWORD create $db`

  mysqldump --add-drop-table $db --password=$LOCAL_PASSWORD | mysql -h $REMOTE_HOST --password=$REMOTE_PASSWORD $db

  echo "....[OK]";

  esac
