日常常用mysql建庫備份shell

1.不登陸數據庫，批量創建數據庫

#!/bin/bash
PATH="/usr/local/mysql/bin:$PATH"
MYUSER=root
MYPASS=123456
SOCKET=/tmp/mysql.sock
MYCMD="mysql -u$MYUSER -p$MYPASS -S $SOCKET"
for dbname in shunmai langwenke guirentong
  do 
    $MYCMD -e "create dabases dbname"
  done

2.不登錄數據庫備份

#!/bin/bash
PATH="/usr/local/mysql/bin:$PATH"
DAPATH=/data/backup
MYUSER=root
MYPASS=123456
SOCKET=/tmp/mysql.sock
MYCMD="mysql -u$MYUSER -pMYPASS -S $SOCKET"
MYDUMP="mysqldump -u$MYUSER -pMYPASS -S $SOCKET"
[ ! -d "$DAPATH" ] && mkdir $DAPATH
for dbname in `$MYCMD -e "show databases;"|sed '1,2d'`|egrep -v "mysql|test"
  do
    $MYDUMP $dbname |gzip >$DAPATH/${dbname}_$(date +%F).sql.gz
  done

3.不登錄數據庫批量建表，添加數據

#!/bin/bash
PATH="/usr/local/mysql/bin:$PATH"
DBPATH=/data/backup
MYUSER=root
MYPASS=123456
SOCKET=/tmp/mysql.sock
MYCMD="mysql -u$MYUSER -pMYPASS -S $SOCKET"
MYDUMP="mysqldump -u$MYUSER -pMYPASS -S $SOCKET"
for dbname in shunmai langwenke haibei guirentong
  do
    $MYCMD -e "use $dbname;create  table test (id int,name varchar(16)); insert into test values(1,'testdata');"
  done 

4.不登陸數據庫查表

#!/bin/bash
PATH="/usr/local/mysql/bin:$PATH"
MYUSER=root
MYPASS=123456
SOCKET=/tmp/mysql.sock
MYCMD="mysql -u$MYUSER -pMYPASS -S $SOCKET"
for dbname in shunmai langwenke haibei guirentong
  do
    echo =================${dbname}.test================
      $MYCMD -e "use $dbname;select * from ${dbname}.test;"
  done

5.不登陸數據庫，批量備份

#!/bin/bash
PATH="/usr/local/mysql/bin:$PATH"
DBPATH=/data/backup
MYUSER=root
MYPASS=123456
SOCKET=/tmp/mysql.sock
MYCMD="mysql -u$MYUSER -pMYPASS -S $SOCKET"
MYDUMP="mysqldump -u$MYUSER -pMYPASS -S $SOCKET"
  [ ! -d "$DAPATH" ] && mkdir $DBPATH
  for dbname in `$MYCMD -e "show databases;"|sed '1,2d'|egrep -v "mysql|schema"`
    do
      mkdir $DBPATH/${dbname}_$(date +%F) -p
      for table in `$MYCMD -e "show tables from $dbname;"|sed '1d'`
        do
          $MYCMD $dbname $table|gzip >$DBPATH/${dbname}_$(date +%F)/${dbname}_$(table).sql.gz
        done
    done
