mongodb的参数说明：
--dbpath 数据库路径(数据文件)
--logpath 日志文件路径
--master 指定为主机器
--slave 指定为从机器
--source 指定主机器的IP地址
--pologSize 指定日志文件大小不超过64M.因为resync是非常操作量大且耗时，最好通过设置一个足够大的oplogSize来避免resync(默认的 oplog大小是空闲磁盘大小的5%)。
--logappend 日志文件末尾添加
--port 启用端口号
--fork 在后台运行
--only 指定只复制哪一个数据库
--slavedelay 指从复制检测的时间间隔
--auth 是否需要验证权限登录(用户名和密码)
