First, import the package-managed public key.

Ubuntu package management tools (i.e. dpkg and apt) require publishers to sign packages with GPG keys to ensure package consistency and authenticity.

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

Then, create MongoDB data source files

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

Update data sources.

sudo apt-get update

Some of the addresses in the update are disconnected.

install MongoDB

deb [ arch=amd64 ] http://mirrors.aliyun.com/mongodb/apt/ubuntu bionic/mongodb-org/4.0 multiverse

Error: Unable to locate package mongodb-org, package not found. It may be caused by a previously updated data source not connecting.

Change the data source address of mongdb to Ali's

deb [ arch=amd64 ] http://mirrors.aliyun.com/mongodb/apt/ubuntu bionic/mongodb-org/4.0 multiverse

Re-update the data source

Install mongodb again and wait for installation to complete.

Start mongodb

sudo service mongod start

Check if startup is successful

ps aux | grep mongod

MongoDB installation startup complete.
