前言

在Centos7默认仓库没有Mongodb下载源，大家可通过Mongodb官网下载源码包自行编译或者下载Mongodb官方yum仓库进行安装。这里要示范的是通过yum源进行安装Mongodb5.0.5。

官方下载地址

安装

下载Mongodb的repo源

Mongodb repo源：https://repo.mongodb.org/yum/redhat/7/mongodb-org/5.0/x86_64/RPMS/

根据自己服务器系统版本，选择对应的RPM包下载。若使用命令行方式下载，可在shell下使用 wget 下载。

安装Mongodb之前需要将对应版本的依赖包也一起下载下来。

wget https://repo.mongodb.org/yum/redhat/7/mongodb-org/5.0/x86_64/RPMS/mongodb-org-5.0.5-1.el7.x86_64.rpm

wget https://repo.mongodb.org/yum/redhat/7/mongodb-org/5.0/x86_64/RPMS/mongodb-org-mongos-5.0.5-1.el7.x86_64.rpm

wget https://repo.mongodb.org/yum/redhat/7/mongodb-org/5.0/x86_64/RPMS/mongodb-org-server-5.0.5-1.el7.x86_64.rpm

wget https://repo.mongodb.org/yum/redhat/7/mongodb-org/5.0/x86_64/RPMS/mongodb-org-shell-5.0.5-1.el7.x86_64.rpm

wget https://repo.mongodb.org/yum/redhat/7/mongodb-org/5.0/x86_64/RPMS/mongodb-org-tools-5.0.5-1.el7.x86_64.rpm

安装Mongodb

下载后先安装依赖，再安装Mongodb

rpm -ivh mongodb-org-mongos-5.0.5-1.el7.x86_64.rpm

rpm -ivh mongodb-org-server-5.0.5-1.el7.x86_64.rpm

rpm -ivh mongodb-org-shell-5.0.5-1.el7.x86_64.rpm

rpm -ivh mongodb-org-tools-5.0.5-1.el7.x86_64.rpm

rpm -ivh mongodb-org-5.0.5-1.el7.x86_64.rpm

启动Mongodb服务

systemctl start mongod

检查其运行状态

systemctl status mongod

输出：

开机启动Mongodb服务

systemctl enable mongod

如果您正在运行防火墙(firewalld)，则还需要打开27017端口：

firewall-cmd --permanent --zone=public --add-port=27017/tcp

firewall-cmd --reload
