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
