--合服逻辑

--[=[
    0.一般在跨服上进行合服, 所以需要把merge目录下所有文件更新到跨服上

    1.更新MergeServerDefine.MERGE_DB_TB中要合并的数据库, 并备份数据库, 方法见 MergeServerDefine

    2.[可选] 先执行一次start.sh, 再杀掉所有游戏服的进程。因为重启游戏服时会根据条件删除一些数据, 这样合服时要处理的数据就少了一些。
        比较前面的游戏服的邮件数据可能有异常, 可先执行/server/cleanExpireMail.sh清理下异常的邮件(需要修改脚本中数据库范围)

    3.将跨服的bin*文件 的/script 目录下的启动文件Main.lua暂时改为其他名字, MainMerger改为Main.lua，合服完毕后再改回来。

    4.检查MergeServerDefine中的MERGE_DB_TB数据库名是否正确, 如果正确则和正常启动游戏一样启动游戏服, 开始进行合服

    5.查看日志oss_merge, 是否有报错, 如果有报错则还原数据, 恢复见方法见 MergeServerDefine

    6.修改mysql区服列表的 port, dbName, megre_server字段, 被合服的 port 和 dbname 要改为目标服一样, 被合服的 megre_server字段更新为1。
        sql见sdk数据库下查询中的updateMergeServerData(需要修改数据库范围)

    7.修改linux上被合服的bin*文件名, 防止 start.sh 启动时会把被合服也启动起来。脚本见/server/changebinName.sh  (需要修改脚本中范围)

    8.合服完毕, 将步骤3修过的文件名改回原来的名字, 执行start.sh 启动游戏服。
