系列文章總目錄：Python數(shù)據(jù)分析及可視化實(shí)例目錄

---

我不是程序員，也不是設(shè)計(jì)師，我只是碰巧有一些想法和一臺電腦。
I am not a designer nor a coder. I'm just a guy with a point-of-view and a computer.

Step1.配置 yum

vim /etc/yum.repos.d/MongoDB-org-3.4.repo

在其中輸入

[mongodb-org-3.4] name=MongoDB Repository baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/testing/x86_64/ gpgcheck=1 enabled=1 gpgkey=https://www.mongodb.org/static/pgp/server-3.4.asc

然后輸入如下命令進(jìn)行安裝

sudo yum install -y mongodb-org

如果想要安裝其他版本的Mongodb可以點(diǎn)開參考鏈接里面有更詳細(xì)的安裝指南。

服務(wù)管理

service mongod start #啟動 service mongod stop #停止 service mongod restart #重啟

Step2.配置Mongodb

配置文件路徑: /etc/mongod.conf。

若要自己指定數(shù)據(jù)存儲位置和日志的存儲位置，我們可以修改MongoDB的配置文件。

舉個(gè)例子:

若要將數(shù)據(jù)文件存儲在 /home/data/mongo

日志文件存儲在 /home/data/log/mongodb.log

注意: 這兩個(gè)存儲的位置要給MongoDB足夠的權(quán)限來操作，否則會報(bào)錯(cuò)

則將配置文件對應(yīng)部分修改，其他不變

# where to write logging data. systemLog: destination: file logAppend: true path: /home/data/log/mongod.log # Where and how to store data. storage: dbPath: /home/data/mongo journal: enabled: true

然后，通過指定配置文件啟動MongoDB。

mongod -f /etc/mongod.conf

默認(rèn)會在后臺運(yùn)行，出現(xiàn)信息

about to fork child process, waiting until server is ready for connections.

forked process: 10286

child process started successfully, parent exiting

如果沒有后臺運(yùn)行，可以檢查配置文件中

# how the process runs

processManagement:

fork: true # 這里是不是 true

直接使用命令來后臺運(yùn)行MongoDB

mongod –fork –dbpath [dbpath] –logpath [logpath]

這里 [dbpath] 是數(shù)據(jù)文件夾的路徑，[logpath] 是日志文件的路徑。
例如，還是上面的存儲位置，
數(shù)據(jù)文件存儲在 /home/data/mongo
日志文件存儲在 /home/data/log/mongodb.log
mongod –fork –dbpath /home/data/mongo –logpath /home/data/log/mongodb.log
關(guān)閉后臺運(yùn)行

Step3.終端運(yùn)行

mongo use admin db.shutdownServer()

提示：

啟動服務(wù)前，先查看一下端口是否被占用，若被占用可以添加 –port 參數(shù)來指定端口。

netstat -ap | grep [port]

關(guān)閉后臺運(yùn)行的指定了其他端口的MongoDB，連接數(shù)據(jù)庫時(shí)也要加端口號。

mongo localhost:port

Step4.消除警告
