1、下載：https://www.mongodb.org/dl/linux/mongodb-linux-x86_64-rhel62-3.6.21-rc2.tgz
2、解壓：tar -xvf mongodb-linux-x86_64-rhel62-3.6.21-rc2.tgz -C /usr/local/mongodb
3、相關目錄建立：

資料庫：mkdir -p /usr/local/application/mongodb/data

日誌：touch /usr/local/application/mongodb/logs

配置檔案：touch /usr/local/mongodb/mongodb.conf

配置檔案內容如下：

dbpath=/usr/local/application/mongodb/data
logpath=/usr/local/application/mongodb/logs
port=27017
fork=true
logappend=true

4、開機啟動：vim /etc/rc.local，最後新增：/usr/local/mongodb/bin/mongod --dbpath=/usr/local/application/mongodb/data --logpath=/usr/local/application/mongodb/logs --logappend  --auth --port=27017
配置檔案啟動：/usr/local/mongodb/bin/mongod --config /usr/local/mongodb/mongodb.conf
