棋牌类游戏框架

技术基于node.js，写这个东西是因为最近接触了一部分棋牌的代码，过程实在是不那么让人愉快，代码规范性，可读性，稳定性，扩展性都不好。于是想用一个能够快速开发的工具来实现一个自己的框架。

center_svr  目前只做监控和服务器间的列表维护
gate_svr    用户请求转发到服务器
login_svr   用户帐号及登录授权
hall_svr    游戏信息及游戏服务器信息
game_svr    游戏服务器

除了center_svr以外，其它的服务器都可以水平扩展，可以多台分布式布署。center_svr是设计中的单点。
客户端与网关间应该只有一个连接，在开发阶段客户端可直连游戏服务器，不通过网关，降低调试复杂度。
对于多个同类服务器，使用随机访问的方式进行负载均衡。
服务器间通信协议都使用json，因为简单，好调试，易扩展。
服务间通信是自己模拟的rpc通信，需要严格的稳定性的话，要使用专门的rpc组件来实现。包括leader选举，广播等。目前的实现方式的问题在于，服务宕机了，不能及时通知到所有的服务。服务在调用时还需要自行判定被调者是否存活。

游戏服务器包含多个房间，每个房间参数可配置，每个房间里有一个桌子，每个桌子有玩家。由于node.js的天性，它是io处理强，cpu计算弱的。所以不要在游戏服务器中添加大量的计算类任务。

数据库使用SQL拼接的方式来写的。练手，练手。正确的做法是使用orm组件，避免大量重复的代码。

第三方游戏支付：
骏付通
爱贝

没想到这个项目有了这么多star……………………由于身体健康原因，项目停止了两年多了。

中央服务器

功能：服务注册，服务查询
每一类服务器都有一个单独编号，编号是递增的。如果服务停掉了，这个编号可能会被下一个启动的服务使用。
每个服务都可以带有扩展信息，但是不建议使用，因为一旦添加了扩展信息就意味着中央服务器要修改，中央服务器修改后就需要重启。而中央服务器是单点，一重启就会导致客户端全部掉线。这个编号是给客户端用的，但同一个游戏有多个服务器的时候，用户连上网关以后，网关需要根据这个编号去找对应的服务器。否则就要保证服务端端口永不重复。

游戏服务器可以水平扩展。
游戏通过插件方式写在plugin目录下，同时将插件信息配置到config/sys-config中。
每个游戏一到多个游戏服务器，但不支持一个游戏服务器跑多个游戏。
每个游戏服务器有多个房间列表，房间相关配置信息在数据库中。玩家也可以自定义房间配置，覆盖默认的数据库中的配置。
游戏服务器启动后会自动往center服务器上报自己的信息。
游戏服务器会调用插件中的方法，如果插件不实现某个方法将会导致整个服务崩溃。
每个服务可开启的房间数是有上限的，现在限制为2000个房间。

gate服务的设计原则

gate服务按固定时间间隔上报状态到center服务器
gate服务按固定时间间隔获取所有类型服务器列表（列表不能过超过1M大小，超过了redis会有卡顿现象）
gate服务器在玩家登陆请求时转发请求到登陆服务器
登录成功后，gate服务器在收到客户端连接游戏服务器请求时，在指定的游戏服务器建立连接，打通客户端和游戏服务器
gate服务器在玩家游戏时，将请求转发到固定的游戏服务器，带上一个玩家序号，这个序号可以是固定的玩家ID，没有玩家ID可以是一个伪ID，类似于socket fd这样的东西。（伪ID在被攻击时会产生严重的问题，就是ID耗尽溢出，回绕的时候怎么和正常ID不冲突，这个问题现在是没处理的）
游戏服务器回包以后，gate服务器通过包内的玩家序号找到对应的玩家（注意不是请求序号，如果是请求序号一个玩家可能对应多个请求）

为了解耦模块间的关联，gate服务器对消息的处理应该统一化，尽量不要有特殊处理。或者说是做成插件化，特殊的业务都在插件中完成
