Linux安裝mongoDB__Linux

環境：viretualBox Redhat7.0   mongoDb3.6

步驟：

1.安裝虛擬機器：詳細請查看Linux安裝ReaHat  基本是下一步下一步即可

2.安裝MongoDb

需要工具Xshell，如果自己沒有請聯絡我給你發送

       mongoDB的tar包下載地址：https://www.mongodb.com/download-center#atlas

      使用xshell工具將安裝包拷貝到虛擬機器中

      解壓安裝包    tar -zxvf     xxxxxxxxxx.tar

      移動到安裝目錄    mv mongodb-linux-x86_64-xxx     /usr/local/mongodb

       添加環境變數    echo "export PATH=\$PATH:/usr/local/mongodb/bin【解壓後移動過去會存在一個目錄，所以需要配置】" > /etc/profile.d/mongodb.sh    （這個裡面要小心了。）

      使環境變數生效    source /etc/profile.d/mongodb.sh

      建立Mongodb使用者和組  useradd -r -M -s /sbin/nologin mongod

     ***建立啟動資料庫和開機記錄  mkdir -p /data/mongodb/{db,log}/   【為什麼是這個請查看指令碼中配置的使用者和組】

     修改許可權        chown -R mongod:mongod /data/mongodb/

    配置mongoDB設定檔：    vi /etc/mongod.conf

   

# mongod.conf# for documentation of all options, see:#   http://docs.mongodb.org/manual/reference/configuration-options/# where to write logging data.systemLog:  destination: file  logAppend: true  path: /data/mongodb/log/mongod.log# Where and how to store data.storage:  dbPath: /data/mongodb/db  journal:    enabled: true#  engine:#  mmapv1:#  wiredTiger:# how the process runsprocessManagement:  fork: true  # fork and run in background  pidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile# network interfacesnet:  port: 27017  bindIp: 127.0.0.1  # Listen to local interface only, comment to listen on all interfaces.#security:#operationProfiling:#replication:#sharding:## Enterprise-Only Options#auditLog:#snmp:

備忘：


如果MongoDB連接埠不在27017-27019, 28017-28019之間，需要執行以下步驟：


# yum -y install policycoreutils-python


# semanage port -a -t mongod_port_t -p tcp <port_number>   27017

建立MongoDB自啟動指令碼     vi /etc/init.d/mongod

設定MongoDB服務開機自啟動

chmod +x /etc/init.d/mongod chkconfig mongod on 啟動MongoDB服務 service mongod start

如果啟動不成功：

   主要查看     啟動指令碼 .sh 檔案中的配置的環境變數是否正確，  同時查看db  log的許可權是否是指令碼中配置的使用者和組，同時可執行，我給的777

驗證啟動成功：

service mongod status

Mongodb編輯：

輸入mongo:

> db.foo.find();{ "_id" : ObjectId("5a34a3de8420293d5f46b0ee"), "name" : "xiaonanhai", "age" : "23" }> show dbs;admin   0.000GBconfig  0.000GBlocal   0.000GBtest    0.000GB>
