shell批量增删改查百库百表(mysql)

我的博客已迁移到xdoujiang.com请去那边和我交流
一、基础环境
1、版本
cat /etc/debian_version
7.8

2、内核
uname -r
3.2.0-4-amd64

3、ip(eth0)
10.1.10.117
10.1.10.185

4、2台机器上都设置权限
grant all privileges on `xxx%`.* to 'jimmy'@'10.1.10.%' identified by 'redhat';
flush privileges;

5、要注意数据库必须监听在相应本机IP地址上

二、shell脚本函数说明
redirectlog           #记录日志
createdb              #创建库
createtb              #创建表

三、具体代码
cat createdbtb.sh
#!/bin/bash

currdate=$(date +%Y%m%d)
dbuser="jimmy"
dbpass="redhat"
logdir="/root/log"
tmptb="table.sql"
tmpdb="db.sql"
function redirectlog ()
{
logfile=$logdir/${currdate}log
mkdir -p $logdir
exec 1>$logfile
exec 2>$logfile
}
function createdbsql ()
{
cat <<EOF > $tmpdb
create database $1
EOF
}
function createdb ()
{

while [[ $dbfront -lt $dbend ]]
do
dbx=`printf "%02d" $dbfront`
createdbsql xxx$dbx
cat $tmpdb|mysql -u"$dbuser" -p"$dbpass" -h"$1"
let "dbfront+=1"
done
}
function createtbsql ()
{
cat <<EOF > $tmptb

) ENGINE=innodb, CHARSET=utf8;
EOF
}
function createtb ()
{

dbend=100
tablefront=0
tableend=100
while [[ $dbfront -lt $dbend ]]
do

cat $tmptb|mysql -u"$dbuser" -p"$dbpass" -h"$1" "xxx$dbx"
let "tablefront+=1"
done
let "dbfront+=1"
let "tablefront=0"
done
}
redirectlog
