Install mongodb packages

To install the latest stable version of MongoDB, run the following command:

Yum install-y mongodb-org

To install a specific version of MongoDB, specify each package separately and append the version number to the package name, as follows:

Yum install-y mongodb-org-4.2.0 mongodb-org-server-4.2.0 mongodb-org-shell-4.2.0 mongodb-org-mongos-4.2.0 mongodb-org-tools-4.2.0

(note: each version of the .repo file can be found in the repository. Odd releases (such as 3.5) are development versions and are not suitable for production use. )

If the installation is successful, you will see the installed package, as follows:

two。 Install mongodb using the Tar package

MongoDB .tar.gz tarballs requires the following dependencies to be installed:

Yum install libcurl openssl

Download the MongoDB .tar.gz tarball link:

Https://www.mongodb.com/download-center/community?jmp=docs

Select the appropriate version, os, and the package type is shown below:

Extract the package to / usr/local

Tar xf mongodb-linux-x86_64-rhel70-4.2.0.tgz-C / usr/local/

Renamed to mongodb

Mv mongodb-linux-x86_64-rhel70-4.2.0 / usr/local/mongodb

The executable file for MongoDB is located in the bin directory and added to the PATH path:

Export PATH=/bin:$PATH

The installation path for your MongoDB. Mine is / usr/local/mongodb

[root@localhost local] # echo 'export PATH=/usr/local/mongodb/bin:$PATH' > > ~ / .bashrc

[root@localhost local] # source ~ / .bashrc

Create a data directory for mongodb:

MongoDB's data is stored in the db directory of the data directory, but this directory is not automatically created during installation, so you need to manually create the data directory and create the db directory in the data directory. (otherwise an error will be reported at startup)

Note: / data/db is the default startup database path for MongoDB. If you want to modify it, you need to specify the option-dbpath at startup. To see more options, execute mongod-help.

[root@localhost local] # mkdir-p / data/db

Run the mongodb service in the background and specify the log path:

[root@localhost~] # mongod-- fork-- logpath / data/mongodb/logs/mongodb.log

MongoDB backend management Shell:

MongoDB Shell is an interactive Javascript shell that comes with MongoDB, which is used to operate and manage MongoDB.

[root@localhost ~] # mongo

It was built successfully. (use kill-2 to close when closing, otherwise it will cause database corruption or lock release failure)
