python生成1000w的mysql测试数据

支持参数，可以不加参数

-p 存储路径 （默认/root/t100w.sql）

-n 生成多少条数据 (默认 1000001)

        '''
        path = option.path if option.path else '/root/t100w.sql'
        num = int(option.num) if option.num else 1000001
        return path,num

if __name__ == '__main__':
    op = optparse.OptionParser()
    op.add_option('-p','--path',dest="path",help="目标路径")
    op.add_option('-n', '--num', dest="num", help="生成数量")
    option,argv = op.parse_args()
    path,num = verify_argv(option)
    createinsert(path,num)

 使用方法

python s.py  -p /data/t1.sql -n 100000

生成后，登录mysql

source /data/t1.sql
