NoSQL Mongodb--ubuntu Installation

MongoDB only offers a 64-bit lts (long-term support) version of Ubuntu packages. For example, 12.04 lts,14.04 lts,16.04 LTS and so on.

1. Import the public key used by the package management system

Ubuntu Package management Tools (for example: dpkg and apt) require resellers to use GPG keys to sign packages to ensure the consistency and authenticity of the scenario. Use the following command to import the MongoDB public GPG key.

sudo apt-key adv--keyserver HKP://keyserver.ubuntu.com:80--recv EA312927

2. Create a MongoDB list file

Select the following command for different versions to create the/etc/apt/sources.list.d/mongodb-org-3.2.list listfile:

Ubuntu 12.04:

" Deb Http://repo.mongodb.org/apt/ubuntu precise/mongodb-org/3.2 Multiverse " | sudo tee/etc/apt/sources.list.d/mongodb-org-3.2. List

Ubuntu 14.04:

" Deb Http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.2 Multiverse " | sudo tee/etc/apt/sources.list.d/mongodb-org-3.2. List

Ubuntu 16.04:

" Deb Http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 Multiverse " | sudo tee/etc/apt/sources.list.d/mongodb-org-3.2. List

3. Reload the package database

Issue the following command to reload the local package database:

sudo apt-get update

4. Install MongoDB Package Packages

You can install the latest stable version of MongoDB or a specific version of MongoDB.

4.1 Installing MongoDB Latest stable version

sudo apt-get install-y mongodb-org

4.2 Installing MongoDB Specific Version

To install a specific version, you must specify each component package separately with the version number, as an example:

sudo apt-get install-y mongodb-org=3.2. 9 mongodb-org-server=3.2. 9 mongodb-org-shell=3.2. 9 mongodb-org-mongos=3.2. 9 mongodb-org-tools=3.2. 9

If you only install mongodb-org = 3.2.9, do not include component packages, regardless of the version you specify will install the latest version of each MongoDB package.

Although you can specify any version that is available for MongoDB, Apt-get will upgrade the package when a new version of the package is available. To prevent accidental escalation of packages, a fixed (Pin) package is required. The following commands are implemented:

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

5. Create a system service file (for Ubuntu 16.04)

Under/lib/systemd/system/mongod.service, create a Mongod.service file with the following content:

 
[Unit]
Description=High-performance, schema-free document-oriented database
After=network.target
Documentation=https://docs.mongodb.org/manual  [Service]
User=mongodb
Group=mongodb
ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf

[Install]
WantedBy=multi-user.target

To use root permissions here, you can first create a mongod.service file with the above content on the desktop and then use the console's MV command to move to the specified folder:

mv/home/wangchao/Desktop/mongod.service/lib/systemd/system

6. Running MongoDB

The MongoDB instance is stored by default in its data file/var/lib/mongodb and log file/var/log/mongodb, using MongoDB user account to run MongoDB. You can specify the replacement log and data file directory through the/etc/mongod.conf file. If you want to switch users to run MongoDB processes, you must enable these users to gain access to the/var/lib/mongodband/var/log/mongodb directories.

6.1Start MongoDB

sudo service Mongod start

6.2Stop MongoDB

sudo service Mongod stop

6.3Restart MongoDB

sudo service mongod restart

7. Uninstall Mongodb7.1stop MongoDB

sudo service Mongod stop

7.2Remove Packages

sudo apt-get purge mongodb-org*

7.3Remove Data Directories

sudo rm-r/var/log/-R/var/lib/mongodb
