一.服务器端命令
可以只使用mongod命令按照默认配置启动（比如：db dir 是/data/db，port是27017）。
介绍命令参数
1 –v，–verbose 显示详细的日志信息
2 –quiet 安静输出日志信息
客户端shell执行命令时，不管正确与否，在服务端不再显示日志信息。
3 –port arg 指定端口，客户端访问时也要指定相同的参数访问。
4 –bind_ip arg 指定绑定的IP地址，其他地址无法访问该服务。默认为all
5 –ipv6 开启IPv6的支持，默认不开启
.
6 –maxConns arg 设置mongodb的最大连接数
默认最大连接数是100万
7 –logpath arg 设置日志的路径
将日志写入到指定的文件(如：out.log)，代替标准输出
8 –syslog 将日志写入到系统的日志设备来代替写入到指定文件的标准输出
.
9 –logappend 将日志追加到日志文件中
.
10 –logRotate arg 设置日志轮转的行为（rename | reopen）
11 –timeStampFormat arg 设置时间格式化（ctime,iso8601-utc,iso8601-local 三选一，不过一般选择iso8601-local符合我们的使用习惯）
12 –pidfilepath arg pidfile的全路径，不设置pidfile不会被创建
.
13 –keyFile arg 集群认证的私有key
.
14 –setParameter arg 设置配置参数
.
15 –httpinterface 开启http访问接口 。使用–rest 更好一些
显示http访问页面结果，
16 –rest 开启简单的rest API
17 –clusterAuthMode arg 集群权限的权限模式，包括keyFile,sendKeyFile,sendX509,x509
18 –nounixsocket 禁用unix socket监听
19 –unixSocketPrefix arg 替换unix domain socket的默认目录(/tmp)
20 –filePermissions arg 设置socket文件权限(默认为0700)
.
21 –fork fork服务进程
.
22 –auth 开启安全运行
23 –noauth 开启非安全运行，与—auth相反
24 –jsonp 允许jsonp通过http访问
.
25 –profile arg 0=off 1=slow, 2=all
.
26 –sysinfo 显示部分诊断系统信息
27 –noIndexBuildRetry 被shutdown中断后，不再进行任何的索引构建重试
28 –noscripting 禁用脚本引擎
.
29 –notablescan 禁止表扫描
.
30 –shutdown 停掉一个运行的服务
