根据mongodb官网提供的教程安装：
1.创建mongdb-org-3.4.repo
2.使得selinux的config为disabled
3.yum -y install mongodbxxxxxx
4.配置/etc/mongod.conf
5.service mongod start
[root@bogon yum.repos.d]# touch mongodb-org-3.4.repo
[root@bogon yum.repos.d]# ls
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo
CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo mongodb-org-3.4.repo
[root@bogon yum.repos.d]# vi mongodb-org-3.4.repo
[root@bogon yum.repos.d]# yum install -y mongodb-org
