MySQL的本地备份和双机相互备份脚本: 首先,我们需要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用户里添加用户。 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 case "$1" in first) echo -n "Crate db [ $db ] on $REMOTE_HOST first!" result=`mysqladmin -h $REMOTE_HOST --password=$REMOTE_PASSWORD create $db` if [ ! $result ]; then echo "...Done!"; else echo "...Fialed! check your configure plz!"; echo "Remote host said: $result"; exit fi ;; local) # back up to localhost dir. if [ ! -d $DB_BACKUP_PATH ]; then mkdir $DB_BACKUP_PATH fi echo -n "[ $db ]....Backup to local$DB_BACKUP_PATH with gzip"; if [ -e "$DB_BACKUP_PATH/$db.gz" ]; then mv $DB_BACKUP_PATH/$db.gz $DB_BACKUP_PATH/$db.1.gz; fi mysqldump --password=Walte#Ming $db | gzip > $DB_BACKUP_PATH/$db.gz echo "...[OK]" ;; *) # Do common Backup! echo -n "[ $db ]...Do Backup! ====>> $REMOTE_HOST/$db"; mysqldump --add-drop-table $db --password=$LOCAL_PASSWORD | mysql -h $REMOTE_HOST --password=$REMOTE_PASSWORD $db echo "....[OK]"; esac else echo "[ $db ]"; echo "***This database set to Not backup!...Operation CANCELED!"; fi else echo "[ $db ]"; echo "***Warning!
