MongoDB社区版本和企业版本差异主要体现在安全认证、系统认证等方面，具体信息参考下表：
这里使用的是企业版，版本是2.6，新版3.2还在开发中。。。
1.添加仓库
[root@VM-248 ~]# vim /etc/yum.repos.d/mongodb-enterprise.repo [mongodb-enterprise-2.6] name=MongoDB Enterprise 2.6 Repository baseurl=https://repo.mongodb.com/yum/redhat/$releasever/mongodb-enterprise/2.6/$basearch/ gpgcheck=0 enabled=1
2.yum安装
[root@VM-248 ~]# yum install -y mongodb-enterprise [root@VM-248 ~]# rpm -qa |grep mongodb mongodb-enterprise-server-2.6.11-1.el6.x86_64 mongodb-enterprise-tools-2.6.11-1.el6.x86_64 mongodb-enterprise-2.6.11-1.el6.x86_64 mongodb-enterprise-sh-2.6.11-1.el6.x86_64 mongodb-enterprise-mongos-2.6.11-1.el6.x86_64
3.修改配置
[root@VM-248 ~]# egrep -v '^$|^#' /etc/mongod.conf logpath=/var/log/mongodb/mongod.log logappend=true fork=true dbpath=/var/lib/mongo pidfilepath=/var/run/mongodb/mongod.pid bind_ip=0.0.0.0 auth=true
4.启动服务
[root@VM-248 ~]# /etc/init.d/mongod start [root@VM-248 ~]# chkconfig mongod on
5.添加密码
[root@VM-248 ~]# mongo
MongoDB sh version: 2.6.11
connecting to: test
> use admin
switched to db admin
> db.addUser('root','password')
WARNING: The 'addUser' sh helper is DEPRECATED. Please use 'createUser' instead
Successfully added user: { "user" : "root", "roles" : [ "root" ] }
> db.system.users.find()
{ "_id" : "admin.root", "user" : "root", "db" : "admin", "credentials" : { "MONGODB-CR" : "29e87d0a8716c4ae20efbcdd9d252f5b" }, "roles" : [ { "role" : "root", "db" : "admin" } ] }
> exit
bye
6.删除密码
> db.system.users.find()
{ "_id" : "test.root", "user" : "root", "db" : "test", "credentials" : { "MONGODB-CR" : "29e87d0a8716c4ae20efbcdd9d252f5b" }, "roles" : [ { "role" : "dbOwner", "db" : "test" } ] }
> db.system.users.remove({user:"root"})
WriteResult({ "nRemoved" : 1 })
> db.system.users.find()
> exit
bye
7.远程连接
cenhuqing@cenhuqingdeMacBook-Pro ~$mongo vm248/admin -u root -p password
MongoDB sh version: 3.0.4
connecting to: vm248/admin
> show dbs;
admin 0.078GB
local 0.078GB
> exit
bye
