CentOS7下使用yum安装Mongodb3.4

实验环境

操作系统：CentOS Linux release 7.3.1611 (Core)

数据库系统： Mongodb 3.4.9-1.el7

IP： 192.168.230.134

创建mongodb3.4的yum源文件

再yum源文件目录中创建mongodb-org-3.4.repo

[root@localhost ~]# vim /etc/yum.repos.d/mongodb-org-3.4.repo

写入仓库文件

[mongodb-org-3.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-3.4.asc

验证yum源文件是否有效

查看mongodb所需安装文件

[root@localhost ~]# sudo yum search mongodb-org
Loaded plugins: fastestmirror, langpacks
mongodb-org-3.4                                                                                             | 2.5 kB  00:00:00

正好就是安装mongodb所需的5个包

安装mongodb所需包

• MongoDB提供的官方安装文件包含以下软件包：

需要注意的是，mongodb-org-server包提供了一个使用/etc/mongod.conf配置文件启动mongod的初始化脚本。

执行yum安装

直接使用快速安装

[root@localhost ~]# sudo yum install -y mongodb-org
