首先從官網(wǎng)下載mongodb的安裝包http://www.mongodb.org/downloads我的系統(tǒng)是redhat5.8所有選擇相應(yīng)的版本包就ok現(xiàn)在最新版是3.0.3
解壓mongodb-linux-x86_64-rhel55-3.0.3.tgz
[root@mongodb ~]# tar zxvf mongodb-linux-x86_64-rhel55-3.0.3.tgz -C /opt/ mongodb-linux-x86_64-rhel55-3.0.3/README mongodb-linux-x86_64-rhel55-3.0.3/THIRD-PARTY-NOTICES mongodb-linux-x86_64-rhel55-3.0.3/GNU-AGPL-3.0 mongodb-linux-x86_64-rhel55-3.0.3/bin/mongodump mongodb-linux-x86_64-rhel55-3.0.3/bin/mongorestore mongodb-linux-x86_64-rhel55-3.0.3/bin/mongoexport mongodb-linux-x86_64-rhel55-3.0.3/bin/mongoimport mongodb-linux-x86_64-rhel55-3.0.3/bin/mongostat mongodb-linux-x86_64-rhel55-3.0.3/bin/mongotop mongodb-linux-x86_64-rhel55-3.0.3/bin/bsondump mongodb-linux-x86_64-rhel55-3.0.3/bin/mongofiles mongodb-linux-x86_64-rhel55-3.0.3/bin/mongooplog mongodb-linux-x86_64-rhel55-3.0.3/bin/mongoperf mongodb-linux-x86_64-rhel55-3.0.3/bin/mongod mongodb-linux-x86_64-rhel55-3.0.3/bin/mongos mongodb-linux-x86_64-rhel55-3.0.3/bin/mongo [root@mongodb opt]# ln -sv mongodb-linux-x86_64-rhel55-3.0.3/ mongodb create symbolic link `mongodb' to `mongodb-linux-x86_64-rhel55-3.0.3/'
3.創(chuàng)建mongodb用戶
[root@mongodb /]# useradd mongodb
4.創(chuàng)建相應(yīng)文件目錄并修改權(quán)限
[root@mongodb /]# mkdir /data/db -p [root@mongodb /]# chown mongodb:mongodb /data/ -R [root@mongodb opt]# chown -R mongodb:mongodb /opt/*
5.添加PATH環(huán)境變量在shell下正常訪問mongodb的應(yīng)用工具
[root@mongodb bin]# vim /etc/profile.d/mongodb.sh export PATH=$PATH:/opt/mongodb/bin [root@mongodb bin]# source /etc/profile.d/mongodb.sh [root@mongodb bin]# echo $PATH /usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/opt/mongodb/bin
6.創(chuàng)建mongodb的PID存放目錄
[root@mongodb run]# mkdir /var/run/mongodb [root@mongodb run]# chown mongodb:mongodb /var/run/mongodb/ -R [root@mongodb opt]# mongod --dbpath /data/db/ --logpath /var/log/mongodb.log --logappend --port 27017 --pidfilepath /var/run/mongodb/mongodb.pid --maxConns 250 --rest --httpinterface --fork about to fork child process, waiting until server is ready for connections. forked process: 4060 child process started successfully, parent exiting --maxConns 250 ：表示最大連接數(shù)是250個(gè) --rest --httpinterface : web接口，指定這項(xiàng)28017端口才能啟用 --fork ：后臺(tái)運(yùn)行
7.安裝過程中遇見的問題
裝好之后連接出現(xiàn)以下警告
(1).[root@mongodb ~]# mongo MongoDB shell version: 3.0.3 connecting to: test Server has startup warnings: 2015-06-15T20:27:49.892+0800 I CONTROL [initandlisten] ** WARNING: You are running this process as the root user, which is not recommended. 2015-06-15T20:27:49.892+0800 I CONTROL [initandlisten]
出現(xiàn)這個(gè)問題就查看關(guān)于mongodb的文件權(quán)限，主要是/opt /data/db/ /var/run/mongodb/ /var/log/mongodb.log的權(quán)限因?yàn)閱?dòng)初始化時(shí)以root用戶的權(quán)限在運(yùn)行，所以這些目錄下的權(quán)限可能會(huì)變成root root
(2).[mongodb@mongodb db]$ mongod --dbpath /data/db/ --logpath /var/log/mongodb.log --logappend --port 27017 --pidfilepath /var/run/mongodb/mongodb.pid --maxConns 250 --rest --httpinterface --fork 2015-06-15T17:41:25.721+0800 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/enabled is 'always'. 2015-06-15T17:41:25.721+0800 I CONTROL [initandlisten] ** We suggest setting it to 'never' 2015-06-15T17:41:25.721+0800 I CONTROL [initandlisten] 2015-06-15T17:41:25.721+0800 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is 'always'. 2015-06-15T17:41:25.721+0800 I CONTROL [initandlisten] ** We suggest setting it to 'never'
修改兩個(gè)參數(shù)即可
echo "never" > /sys/kernel/mm/transparent_hugepage/enabled echo "never" > /sys/kernel/mm/transparent_hugepage/defrag
8.安裝成功并登錄
[root@mongodb ~]# ss -tanlp | grep mongod
0 0 *:27017 *:* users:(("mongod",4095,6))
0 0 *:28017 *:* users:(("mongod",4095,8))

show dbs show database names

show users show users in current database
show profile show most recent system.profile entries with time >= 1ms
show logs show the accessible logger names
show log [name] prints out the last segment of log in memory, 'global' is default
use <db_name> set current database
db.foo.find() list objects in collection foo
db.foo.find( { a : 1 } ) list objects in foo where a == 1
it result of the last line evaluated; use to further iterate
DBQuery.shellBatchSize = x set default number of items to display on shell
exit quit the mongo shell登錄web接口 28017端口
9.關(guān)閉服務(wù)器
(1).[root@mongodb ~]# mongod --shutdown killing process with pid: 3936 (2).[root@mongodb ~]# killall mongod
10.給mongodb編寫配置文件/etc/mongodb.conf
[root@mongodb ~]# grep -v ^# /etc/mongodb.conf logpath=/var/log/mongodb.log logappend=true fork = true dbpath=/data/db pidfilepath = /var/run/mongodb/mongodb.pid rest = true httpinterface = true
啟動(dòng)
[root@mongodb ~]# mongod -f /etc/mongodb.conf
about to fork child process, waiting until server is ready for connections.
forked process: 4169
child process started successfully, parent exiting
[root@mongodb ~]# ss -tanlp | grep mongod
0 0 *:27017 *:* users:(("mongod",4169,6))
0 0 *:28017 *:* users:(("mongod",4169,8))11.用service mongodb * 來啟動(dòng)mongodb
