3：配置本地yum源
[root@vhost2 ~]# cat /etc/yum.repos.d/rhel7.repo
[rhel-yum]
name=rhel7
baseurl=file:///mnt
enabled=1

4：创建mongodb-enterprise.repo源
Create an /etc/yum.repos.d/mongodb-enterprise.repo file so that you can install MongoDB enterprise directly, using yum.
[mongodb-enterprise]
name=MongoDB Enterprise Repository
baseurl=https://repo.mongodb.com/yum/redhat/$releasever/mongodb-enterprise/3.4/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-3.4.asc
5：安装企业版 install -y mongodb-enterprise
WARNING
On RHEL 7.0, if you change the data path, the default SELinux policies will prevent mongod from having write access on the new data path if you do not change the security context.
The MongoDB instance stores its data files in /var/lib/mongo and its log files in /var/log/mongodb by default, and runs using the mongod user account. You can specify alternate log and data file directories in /etc/mongod.conf. See systemLog.path and storage.dbPath for additional information.
If you change the user that runs the MongoDB process, you must modify the access control rights to the /var/lib/mongo and /var/log/mongodb directories to give this user access to these directories.
[root@vhost2 ~]# ls /var/log/mongodb/
mongod.log
[root@vhost2 ~]# ls /var/lib/mongo/
collection-0--2337306620506737398.wt diagnostic.data index-3--2337306620506737398.wt journal mongod.lock storage.bson WiredTigerLAS.wt WiredTiger.turtle

6：启动服务
[root@vhost2 ~]# systemctl start mongod
You can verify that the mongod process has started successfully by checking the contents of the log file at /var/log/mongodb/mongod.log for a line reading
[root@vhost2 ~]# tail -f /var/log/mongodb/mongod.log

MongoDB Enterprise >
Begin using MongoDB.
To help you start using MongoDB, MongoDB provides Getting Started Guides in various driver editions. See Getting Started for the available editions.
Before deploying MongoDB in a production environment, consider the Production Notes document.
Later, to stop MongoDB, press Control+C in the terminal where the mongod instance is running.
最后，Uninstall MongoDB
Uninstall MongoDB To completely remove MongoDB from a system, you must remove the MongoDB applications themselves, the configuration files, and any directories containing data and logs. The following section guides you through the necessary steps. WARNING This process will completely remove MongoDB, its configuration, and all databases. This process is not reversible, so ensure that all of your configuration and data is backed up before proceeding. 1 Stop MongoDB. Stop the mongod process by issuing the following command: sudo service mongod stop 2 Remove Packages. Remove any MongoDB packages that you had previously installed. sudo yum erase $(rpm -qa | grep mongodb-enterprise) 3 Remove Data Directories. Remove MongoDB databases and log files. sudo rm -r /var/log/mongodb sudo rm -r /var/lib/mongo
