一、下载软件
[root@db1 opt]# ls
mongodb-linux-x86_64-rhel70-4.0.14.tgz 二、解压
[root@db1 opt]# tar xf mongodb-linux-x86_64-rhel70-4.0.14.tgz三、下载依赖软件
[root@db1 mongodb]# yum install -y openssl libcurl四、创建目录
[root@db1 mongodb]# mkdir /opt/mongo_27017/{conf,log,pid} -p
[root@db1 mongodb]# mkdir /data/mongo_27017五、编写配置文件
[root@db1 mongo_27017]# cat >/opt/mongo_27017/conf/mongodb.conf<<EOF
> systemLog:
> destination: file
> logAppend: true
> path: /opt/mongo_27017/log/mongodb.log

> EOF六、启动
[root@db1 mongo_27017]# /opt/mongodb/bin/mongod -f /opt/mongo_27017/conf/mongodb.conf
about to fork child process, waiting until server is ready for connections.
forked process: 13407
child process started successfully, parent exiting七、编写环境变量
[root@db1 mongo_27017]# echo 'export PATH=/opt/mongodb/bin:$PATH' >> /etc/profile
[root@db1 mongo_27017]# source /etc/profile八、进入mongo
[root@db1 mongo_27017]# mongo

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).
The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.
To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

test十七、切换库(创建)
> use wang
switched to db wang
> db
wangmongo默认库在test库下，不需要新建库，直接use，此时库是虚的，只要插入数据才会真正创建
十八、shell命令行查看
[root@db1 ~]# echo "show dbs"|mongo
