1. Offline installation: (in two batches, with and without linux foundation)

Comrades who have the foundation of linux can read:

Install the package:

Installation process

Install the pstree gadget and its use

Close mongodb

Set up boot boot:

Comrades without linux foundation:

First, go to the official to download the offline installation package:

Ftp connects to the server and uploads the offline package

Xshell connection:

Extract the file (you can press the tab key if you type a bit, and it will be completed automatically): tar-xzf mongo*

If the decompression command is not clear, you can go to the document library to see the basic command.

Switch to the root user, copy the folder to the / usr/local directory (where software is usually installed), and rename the folder

Cp-r mongodb-. / usr/local/mv mongodb..../ mongodb

For those who do not understand the command, please see:

Change to the / usr/local/mongodb directory, create a database directory and journal files, and run mongod (. / represents the current directory) in the background.

Mkdir dbstouch logs./mongod-dbpath=/usr/local/mongodb/dbs/-logpath/usr/local/mongodb/logs-fork

View the process and end the process

Pstree-p | grep mongodpkill mongod

If the prompt does not have the pstree command, it means that you are also the smallest installation. Don't panic, just install it.

Yum install-y psmisc (for rest assured applications, you can do-y, fully automated installation, do not rest assured to read one by one)

Is it too troublesome to start? Can be simplified as shown in the figure

If you are using vi for the first time, press I first to enter edit mode. After typing, press esc and enter: wq enter. If you find that you can't get back no matter what you do, don't be afraid, force to withdraw: Q!

Enter. / mongod-f mongod.conf to start

Generally speaking, it is OK to add startup items, and it is also done when playing kali against the sky. The last time ssh can't be started, it is also done the same way. For some reason, centos can't do this, so skip this step.

Change to this directory first: cd / lib/systemd/system

Then create a service for mongodb: vi mongodb.service

Enter the following:

[unit] description=mongodb after=network.target remote-fs.target nss- lookup.target [service] type=forkingexecstart=/usr/local/mongodb/bin/mongod-- config / usr/local/mongodb/bin/mongod.confexecreload=/bin/kill-s hup $mainpidexecstop=/usr/local/mongodb/bin/mongod-- shutdown-- config / usr/local/mongodb/bin/mongod.confprivatetmp= truth [install] wantedby=multi-user.target

Start the service:

Systemctl start mongodb.service

Stop the service:

Systemctl stop mongodb.service

Boot:

Systemctl enable mongodb.service

For those who are not clear, you can read the commonly used linux documents:

After rebooting, I found that mongodb has been booted and self-started!

Now you can delete the initial files.
