Linux下簡單安裝MongoDB
阿新 • • 發佈：2018-12-24
在linux環境下安裝mongoDB，安裝步驟備忘一下。
- 下載完成之後，將包mongodb-linux-i686-3.2.4.tgz上傳到linux系統的/usr/local目錄下；並解壓
[root@centOS-1 local]# tar zxvf mongodb-linux-i686-3.2.4.tgz - 將解壓後的mongoDB的目錄重新命名為mongoDB
[root@centOS-1 local]# mv mongodb-linux-i686-3.2.4 mongoDB- 然後為mongodb建立資料庫存放的位置和日誌檔案,預設是在/data/db下面,為了方便管理，就在mongodb下面建立了相應的目錄；我們在mongodb目錄下新建一個data目錄存放資料、新建一個log目錄存放日誌，然後在該目錄下新建一個日誌檔案，例如我們命名為mongodb.log
[root@centOS-1 local]# cd mongoDB/
[root@centOS-1 mongoDB]# mkdir data
[root@centOS-1 mongoDB]# mkdir log
[root@centOS-1 mongoDB]# touch mongodb.log
[root@centOS-1 mongoDB]#- 進到mongodb下面的bin目錄下檢視mongodb的幫助文件和我們用到的啟動引數
[root@centOS-1 bin]# ./mongod -h- 使用mongod命令建立一個mongodb資料庫連結，資料庫的路徑為/mongodb/data，日誌路徑為/mongodb/log/mongodb.log
；由於我們是32位的linux系統，32bit版本的mongodb預設不開journal記錄，需要在執行時得加上–journal引數，同時mongodb自3.0版本後新增了wiredTiger的資料儲存引擎，而我們的系統採用的是centos版本，預設的wiredTiger不能用,
那麼採用指定引擎為mmapv1；為了在後臺開啟服務程序，需加上–fork引數。
啟動命令如下：
[[email protected]1 bin]# ./mongod --dbpath ../data/ --logpath ../log/mongodb.log --journal --storageEngine=mmapv1 --fork
about to fork child process, waiting until server is ready for connections.
forked process: 1823
child process started successfully, parent exiting
[[email protected] 由此可見mongoDB已經啟動成功。
- 驗證mongoDB是否啟動成功，mongoDB資料庫預設監聽的埠是27017，因此使用netstat命令檢視此埠是否開啟
[root@centOS-1 mongoDB]# netstat -apn|grep 27017
tcp 0 0 0.0.0.0:27017 0.0.0.0:* LISTEN 1823/./mongod
unix 2 [ ACC ] STREAM LISTENING 14442 1823/./mongod /tmp/mongodb-27017.sock
[root@centOS-1 mongoDB]# 可以看到mongoDB已經正確開啟
- 關閉mongDB的方式
也可以進入到mongo資料庫裡面進行操作
./mongo
use admin
db.shutdownServer();
[[email protected]1 bin]# ./mongo

> 設定mongDB開機自啟動
編輯/etc/rc.local檔案，將mongDB的啟動命令寫入到此檔案中即可
/usr/local/mongoDB/bin/mongod –dbpath /usr/local/mongoDB/data/ –logpath /usr/local/mongoDB/log/mongodb.log –journal –storageEngine=mmapv1 –fork[[email protected] ~]# vim /etc/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
#start mongoDB
/usr/local/mongoDB/bin/mongod --dbpath /usr/local/mongoDB/data/ --logpath /usr/local/mongoDB/log/mongodb.log --journal --storageEngine=mmapv1 --fork
