Linux下安裝MongoDB的實(shí)現(xiàn)步驟
Mongo DB 是目前在IT行業(yè)非常流行的一種非關(guān)系型數(shù)據(jù)庫(kù)(NoSql),其靈活的數(shù)據(jù)存儲(chǔ)方式備受當(dāng)前IT從業(yè)人員的青睞。Mongo DB很好的實(shí)現(xiàn)了面向?qū)ο蟮乃枷?OO思想),在Mongo DB中 每一條記錄都是一個(gè)Document對(duì)象。Mongo DB最大的優(yōu)勢(shì)在于所有的數(shù)據(jù)持久操作都無需開發(fā)人員手動(dòng)編寫SQL語句,直接調(diào)用方法就可以輕松的實(shí)現(xiàn)CRUD操作。本文介紹了如何快速安裝mongodb供大家參考。
一、安裝配置mongodb
Step 1: 設(shè)置系統(tǒng)環(huán)境及確保缺省端口27107可用
###當(dāng)前環(huán)境 # cat /etc/issue Red Hat Enterprise Linux Server release 6.5 (Santiago) # vi /etc/selinux/config SELINUX=disabled
Step 2: 下載安裝文件
下載地址： https://www.mongodb.org/downloads. 或者直接在命令提示符下使用curl命令下載 curl -O https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.0.6.tgz
Step 3: 解壓下載的文件
# pwd /usr/local/src # tar -xvf mongodb-linux-x86_64-rhel62-3.0.6.gz ###注，本文直接從網(wǎng)站下載，所以文件為.gz
Step 4: 復(fù)制解壓文件到運(yùn)行目錄
# mkdir -p /var/lib/mongodb # cp -R -n /usr/local/src/mongodb-linux-x86_64-rhel62-3.0.6/. /var/lib/mongodb/
Step 5: 設(shè)置環(huán)境變量
e.g. export PATH=<mongodb-install-directory>/bin:$PATH # vi ~/.bash_profile export PATH=/var/lib/mongodb/bin:$PATH # source ~/.bash_profile
Step 6: 創(chuàng)建數(shù)據(jù)目錄
# mkdir -p /data/mongodata
二、啟動(dòng)及驗(yàn)證mongodb
###啟動(dòng)mongo
# mongod --dbpath /data/mongodata
###以下內(nèi)容為啟動(dòng)后輸出的相關(guān)信息

###停止mongo，直接使用ctrl + c

###修復(fù)啟動(dòng)過程中的兩個(gè)警告，關(guān)于使用root用戶啟動(dòng)mongo的警告先忽略
# echo "never" > /sys/kernel/mm/transparent_hugepage/enabled
# echo "never" > /sys/kernel/mm/transparent_hugepage/defrag
###再次重啟，后置于后臺(tái)進(jìn)程，
# mongod --dbpath /data/mongodata &
###查看啟動(dòng)后的進(jìn)程
# ps -ef|grep mongo |grep -v grep
root 11115 27956 0 10:11 pts/2 00:00:00 mongod --dbpath /data/mongodata
# lsof -i:27017
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
mongod 11115 root 5u IPv4 50567119 0t0 TCP *:27017 (LISTEN)
###使用mongo連接到mongod
# mongo
