1、环境准备：

1mkdir/home/mongodb#创建MongoDB程序存放目录2mkdir/data/mongodata-p#创建数据存放目录3mkdir/data/log/mongolog-p#创建日志存放目录

2、下载：

1curl-Ohttps://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.2.1.tgz

3、安装：

1tarxfmongodb-linux-x86_64-3.2.1.tgz2cdmongodb-linux-x86_64-3.2.13cp-r*/home/mongodb

为了便于命令启动，需要编辑全局变量PATH

1vim/etc/profile.d/mongo.sh2exportPATH=$PATH:/home/mongodb/bin

source/etc/profile.d/mongo.sh

4、启动服务

首先查看mongod的帮助信息

1[root@test~]#mongod--help
启动服务示例：

1mongod--dbpath=/data/mongodata--logpath=/data/log/mongolog/mongodb.log--logappend--fork

查看是否启动：

1netstat-tnlp|grepmongod2tcp000.0.0.0:270170.0.0.0:*LISTEN17909/mongod

以上可看出端口27017已经运行

5、测试

启动mongodb的shell：

1[root@test~]#mongo2MongoDBshellversion:3.2.13connectingto:test4Serverhasstartupwarnings:
