1、环境准备：
1 mkdir /home/mongodb #创建MongoDB程序存放目录 2 mkdir /data/mongodata -p #创建数据存放目录 3 mkdir /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：
1 tar xf mongodb-linux-x86_64-3.2.1.tgz 2 cd mongodb-linux-x86_64-3.2.1 3 cp -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.sh 2 export PATH=$PATH:/home/mongodb/bin
source /etc/profile.d/mongo.sh
4、启动服务

When set to "sccc" keeps server 96 in legacy SyncClusterConnection mode 97 even when the service is running as a 98 replSet 99 --shardsvr declare this is a shard db of a 100 cluster; default port 27018 101 102 Storage options: 103 --storageEngine arg what storage engine to use - defaults 104 to wiredTiger if no data files present 105 --dbpath arg #指定数据目录路径
107 --directoryperdb each database will be stored in a 108 separate directory 109 --noprealloc disable data file preallocation - will 110 often hurt performance 111 --nssize arg (=16) .ns file size (in MB) for new databases 112 --quota limits each database to a certain 113 number of files (8 default) 114 --quotaFiles arg number of files allowed per db, implies 115 --quota 116 --smallfiles use a smaller default file size 117 --syncdelay arg (=60) seconds between disk syncs (0=never, 118 but not recommended) 119 --upgrade upgrade db if needed 120 --repair run repair on all dbs 121 --repairpath arg root directory for repair files - 122 defaults to dbpath 123 --journal enable journaling 124 --nojournal disable journaling (journaling is on by 125 default for 64 bit) 126 --journalOptions arg journal diagnostic options 127 --journalCommitInterval arg how often to group/batch commit (ms) 128 129 WiredTiger options: 130 --wiredTigerCacheSizeGB arg maximum amount of memory to allocate 131 for cache; defaults to 1/2 of physical 132 RAM 133 --wiredTigerStatisticsLogDelaySecs arg (=0) 134 seconds to wait between each write to a 135 statistics file in the dbpath; 0 means 136 do not log statistics 137 --wiredTigerJournalCompressor arg (=snappy) 138 use a compressor for log records 139 [none|snappy|zlib] 140 --wiredTigerDirectoryForIndexes Put indexes and data in different 141 directories 142 --wiredTigerCollectionBlockCompressor arg (=snappy) 143 block compression algorithm for 144 collection data [none|snappy|zlib] 145 --wiredTigerIndexPrefixCompression arg (=1) 146 use prefix compression on row-store 147 leaf pages
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 0 0 0.0.0.0:27017 0.0.0.0:* 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 3 connecting to: test 4 Server has startup warnings: 5 2016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] ** WARNING: You are running this process as the root user, which is not recommended. 6 2016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] 7 2016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] 8 2016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/enabled is 'always'. 9 2016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] ** We suggest setting it to 'never' 10 2016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] 11 2016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is 'always'. 12 2016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] ** We suggest setting it to 'never' 13 2016-01-25T16:12:52.960+0800 I CONTROL [initandlisten] 14 > help 15 db.help() help on db methods 16 db.mycoll.help() help on collection methods 17 sh.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 24 25 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 == 1 34 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。
