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：
1 curl -O https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.2.1.tgz
3、安装：
1tar xf mongodb-linux-x86_64-3.2.1.tgz 2 cd mongodb-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
1 vim /etc/profile.d/mongo.sh2 export PATH=$PATH:/home/mongodb/bin
source /etc/profile.d/mongo.sh4、启动服务
首先查看mongod的帮助信息

启动服务示例：
1 mongod --dbpath=/data/mongodata --logpath=/data/log/mongolog/mongodb.log --logappend --fork查看是否启动：
1 netstat -tnlp | grep mongod 2 tcp 000.0.0.0:270170.0.0.0:* LISTEN 17909/mongod
以上可看出端口27017已经运行
5、测试
启动mongodb的shell：
1 [root@test ~]# mongo 2 MongoDB shell version: 3.2.1 3connecting to: test 4Server has startup warnings: 52016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] ** WARNING: You are running this process as the root user, which is not recommended. 62016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] 72016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] 82016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/enabled is 'always'. 92016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] ** We suggest setting it to 'never'102016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] 112016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is 'always'. 122016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] ** We suggest setting it to 'never'132016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] 14 > help 15 db.help() help on db methods 16 db.mycoll.help() help on collection methods 17sh.help() sharding helpers 18 rs.help() replica set helpers 19 help admin administrative help 20 help connect connecting to a db help 21 help keys key shortcuts 22 help misc misc things to know 23 help mr mapreduce 2425 show dbs show database names 26 show collections show collections in current database 27 show users show users in current database 28 show profile show most recent system.profile entries with time >= 1ms 29 show logs show the accessible logger names 30 show log [name] prints out the last segment of log in memory, 'global' is default 31 use <db_name> set current database 32 db.foo.find() list objects in collection foo 33 db.foo.find( { a : 1 } ) list objects in foo where a == 134 it result of the last line evaluated; use to further iterate 35 DBQuery.shellBatchSize = x set default number of items to display on shell 36 exit quit the mongo shell 37 > show dbs 38 local 0.000GB 39 >
至此，MongoDB3.2.1安装完毕。
