const char *p 和char * const p

1、下载地址 http://www.mongodb.org/ 2、安装前准备
2.1、创建数据目录和日志目录
[root@gflinux4 mongodb]# mkdir -p/opt/mongo/{data,logs}
2.1、创建用户和组
[root@gflinux mongodb]# useradd mongo
[root@gflinux mongodb]# groupadd mongo
groupadd: group mongo exists
2.3更改目录属组
[root@gflinux mongodb]# chown -Rmongo:mongo /opt/mongo/
[root@gflinux mongodb]# ll
total 112244
3、解压
[root@gflinuxmongodb]# tar -zxvf mongodb-linux-i686-2.6.5.tgz
[root@gflinux mongodb]# cd mongodb-linux-i686-2.6.5
[root@gflinux mongodb-linux-i686-2.6.5]# ll
cdtotal 64

4、迁移数据至/usr/local/mongo目录中
4.1拷贝文件至/usr/local/mongo
[root@gflinux4 mongodb]# cp -Rmongodb-linux-i686-2.6.5 /usr/local/mongo
[root@gflinux4 mongodb]# cd/usr/local/mongo/
[root@gflinux4 mongo]# ll
total 64

-rwxr-xr-x 1 root root 23265828 Dec 2503:39 mongotop
4.2、拷贝mongo、mongod到/usr/bin/中
[root@gflinux4 bin]# cp mongo /usr/bin/
[root@gflinux4 bin]# cp mongod /usr/bin/
5、初始化数据和日志目录
[root@gflinux4 ~]# mongod --port 10001--dbpath /opt/mongo/data --logpath /opt/mongo/logs/mongodb.log
2014-12-25T03:45:35.518+0800

2014-12-25T03:45:35.520+0800
[root@gflinux4 data]# pwd
/opt/mongo/data
[root@gflinux4 data]# ll
total 82016

[root@gflinux4 logs]# pwd
/opt/mongo/logs
[root@gflinux4 logs]# ll
total 4
-rw-r--r-- 1 root root 2300 Dec 25 03:45mongodb.log
[root@gflinux4 logs]#
6、连接mongo
[root@gflinux4 logs]# mongo localhost:10001
MongoDB shell version: 2.6.5
connecting to: localhost:10001/test
Welcome to the MongoDB shell.
For interactive help, type"help".

7、测试
http://192.168.88.101:10001/ It looks like you are trying to access MongoDBover HTTP on the native driver port.
8、客户端连接
使用MongoVUE连接。
