树莓派安装mongodb

安装

sudo apt-get install mongodb

错误处理

用以上命令安装完成后，执行 mongo 命令，并没有连接成功

MongoDB shell version: 2.4.14
connecting to: test
Wed Jul 17 22:40:55.765 Error: couldn't connect to server 127.0.0.1:27017 at src/mongo/shell/mongo.js:145
exception: connect failed

查看安装打印的信息中，有这么一条 无法创建主目录"/var/lib/mongodb", 说明 mongodb 缺少权限

sudo service mongodb stop
sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo service mongodb start

修改目录权限后再次执行 mongo 命令，显示连接成功
