我注意到题主提到：
从1开始这样太不好看了
这是万万不可的！电商平台的订单绝对不能给别人看出规律，更不能按顺序增加。因为对手可能通过订单号的规律就能知道你的日销量这些商业信息，这是非常危险的。
我的方案是：
时间+随机数
建议结合实际情况，充分利用时间，随机数，商家ID,会员ID,自增ID这些来组合，根据自身运营特点来制定。
我一般用时间加随机数
当前时间，可以加一串后缀
不仅不好看，别人看你订单号就知道你们网站有多少订单
时间戳加上随机几位数字就可以了
可以网上找一个，时间戳加随机数生成的订单号还是有可能相同的，要杜绝这个
你在建订单表的时候可以指定AUTO_INCREMENT为你想取得一个数，比如10000000，不知道符不符合楼主的意思。
有的是用年月日+订单序号补零，比如2015120600001
订单号基本的原则就是不能重复。
我们公司的后台也有订单号，和前面说的差不多，时间精确到毫秒，然后加一个随机数，基本不会重复的。这是一个订单号，2015120320550551513给你参考下。^_^
关于生成电商订单号，我觉得需要考虑：
订单时间
订单类型
唯一性
不暴露信息
长度适中
可参考开源电商框架生成订单号的源码。
简单讲一楼所说，时间戳+随机。
其实，用uuid是一劳永逸的。

连时间戳都没有，猜去吧。
用时间或者商品类型做出有规则的订单号，这样方便后台管理，前台显示时hash一下，生成散列等长的字串就可以了
