Centos7安装部署MongoDB教程

安装方式：

RPM包安装

安装步骤：

一.下载RPM包

下图是须要注意的事项。其一选择MongoDB的社区版本，默认是企业版本。其二，选中版本后，在下方会出现下载地址，直接复制下载便可

 

 二.安装并查看是否安装成功

 

[root@localhost ~]# rpm -ivh https://repo.mongodb.org/yum/redhat/7/mongodb-org/4.2/x86_64/RPMS/mongodb-org-server-4.2.1-1.el7.x86_64.rpm

三.启动MongoDB

[root@localhost ~]# systemctl start mongod
[root@localhost ~]# systemctl status mongod
