MongoDB在Linux下安裝

mongodb安裝方式

1.下載安裝包並解壓

2.規劃數據庫安裝目錄

shell> mkdir -p /db/mongo/data
shell> mkdir -p /db/mongo/bin
shell> mv mongodb-linux-i686-2.4.10/bin/* /db/mongo/bin/
shell> touch /db/mongo/logs

將/db/mongo/bin加入環境變量,方便直接使用

3.啓動mongodb

shell> mongod --logpath=/db/mongo/logs --logappend --journal --dbpath=/db/mongo/data --port=27017 --fork

4.測試mongodb是否安裝成功

shell> mongo
MongoDB shell version: 2.4.10
connecting to: test

> show dbs                   --列出所有db
local        0.03125GB

> db                         --顯示當前db
test

5.將MongoDB服務加入開機啓動
vi /etc/rc.local在最後追加
mongod --logpath=/db/mongo/logs --logappend --dbpath=/db/mongo/data --port=27017 --fork

mongodb啓動方式

• 命令行方式啓動
• 配置文件方式啓動
  與命令行方式相同，指定語法“選項=值” 區分大小寫
  命令行中如--fork的開關選項其值設置爲true

mongodb停止方式

• 向mongodb服務器發送一個SIGINT或者SIGTERM 信號
• 使用shutdown命令

[1]
使用kill -2|-15  pid
等到當前運行的操作或者文件預分配完成，關閉所有打開的連接，將緩存的數據刷新到磁盤，最後停止
不能使用(kill -9) 導致數據庫直接關閉，使數據文件損壞

[2]
>use admin
> db.shutdownServer()
