用 apt-get 安装

安装 步骤

1.导入包管理系统使用的公钥

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4

2. /etc/apt/sources.list.d/mongodb-enterprise.list 为MongoDB 创建一个文件 。版本-- ubuntu18.04

echo "deb [ arch=amd64 ] http://repo.mongodb.com/apt/ubuntu bionic/mongodb-enterprise/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-enterprise.list

3.重新加载本地包数据库

sudo apt-get update

4.安装MongoDB Enterprise软件包

sudo apt-get install -y mongodb-enterprise

5.安装MongoDB Enterprise的特定版本

sudo apt-get install -y mongodb-enterprise=4.0.3 mongodb-enterprise-server=4.0.3 mongodb-enterprise-shell=4.0.3 mongodb-enterprise-mongos=4.0.3 mongodb-enterprise-tools=4.0.3

6.固定特定版本的MongoDB Enterprise

echo "mongodb-enterprise hold" | sudo dpkg --set-selections
echo "mongodb-enterprise-server hold" | sudo dpkg --set-selections
echo "mongodb-enterprise-shell hold" | sudo dpkg --set-selections
echo "mongodb-enterprise-mongos hold" | sudo dpkg --set-selections
echo "mongodb-enterprise-tools hold" | sudo dpkg --set-selections

运行

默认情况下，MongoDB实例存储

• 它的数据文件 /var/lib/mongodb
• 它的日志文件 /var/log/mongodb

----- 验证MongoDB是否已成功启动:
mongod通过检查日志文件的内容以/var/log/mongodb/mongod.log 获取行读数，验证进程是否已成功启动

sudo service mongod start
sudo service mongod stop
sudo service mongod restart

配置文件：

/etc/mongod.conf

shell 链接

mongodb 的 默认端口 27017

which mongod
which mongo
mongo --port 27017
mongo

客户端连接

mongodb 默认 本地连接
