切换到root用户

apt-get update更新源，源使用的是阿里云的源，感觉速度快，好用。

apt-get mongodb

查看进程是否启动

mongo查看版本

mongodb安装到哪里了呢？

【1】 mongodb的主程序目录在 /usr/bin/下面 mongod

【2】 mongo的log日志的位置/var/log/mongodb/mongodb.log

【3】mongo 配置文件位置 /etc/mongodb.conf

需要创建data/db在/var/lib/mongdb/下面
dbpath 位置 /var/lib/mongdb/data/db

logpath 位置 /var/log/mongdb/mongdb.log

启动mongdb

/usr/bin/mongod -dbpath=/var/lib/mongodb/data/db --auth --port 27017

 --logpath=/var/log/mongodb/mogodb.log --logappend 

cd /usr/bin

./mongod --dbpath=/var/lib/mongodb/data/db --port=27017 --auth --logpath=/var/log/mongodb/mogodb.log --logappend

关闭启动mongodb服务

sudo service mongodb stop
sudo service mongodb start

mongodb启动起来后，需要重新开一个窗口来进行操作

exit退出

重新验证用户权限

报错，没有认证
