如果未提供服务器配置文件，mongodb使用默认的数据库路径/data/db启动，并使用默认端口27017(mongodb)和28017(管理界面）连接到所有的网络IP
重新配置服务器
mongoDB提供3中方式用于配置服务
- 结合mongod守护进程，使用命令行选项。
- 使用setParameter修改设置
- 加载一个配置文件
一般打包的安装包都是用加载一个配置文件，Unix/Linux该配置文件通常位于/etc/mongod.conf
systemLog:

#设置为false,mongodb每次启动都会清空日志，设置为true，所有日志都追加到现有日志后面。

logpath = /var/log/mongodb/mongod.log

}在输出的信息中，可以找到两个最重要的部分：opcounters和asserts。
- opcounters:显示了服务器上已经执行的每种类型的操作数目。对于特定的服务器，计数器的正常值应该在一定范围。
- asserts:显示服务器与客户端抛出异常或警告的数目。如果异常数目迅速增加，应该查看服务器的日志文件以检查服务器是否异常。
