下载mongodb和系统对应的二进制文件

wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.4.9.tgz

解压文件：

tar -xvzf mongodb-linux-x86_64-rhel62-3.4.9.tgz

拷贝到安装目录：

sudo cp -a mongodb-linux-x86_64-rhel62-3.4.9 /usr/local/mongodb

新建数据文件夹：

mkdir -p data/db
mkdir -p data/log
touch /usr/local/mongodb/data/log/mongodb.log

先启动试试：

bin/mongod --dbpath data/db

写mongdb的配置文件：

vim /usr/local/mongodb/mongodb.conf
