1. Download the installation package

Download the installation file for mongoDB

Address: https://www.mongodb.org/downloads#production

Select the Linux 64-bit legacy version and download it to the target server.

Extract the file

Tar-zxvf mongodb-linux-x86_64-3.0.2.tgz

Mv mongodb-linux-x86_64-3.0.2 / workspace/app/mongodb

Enter the extracted directory and set all the files in the bin folder to executable permissions

Chmod-R 755 bin

2, create the data file path

Here, I want to put the data files and log files in the data directory and create the data directory anywhere

Mkdir data

Go to data and create a data file directory

Mkdir db

Assign writeable permissions to the data directory

Chmod-R 755 data

3, write the configuration file

To make it easier for us to start mongoDB, write a configuration file first

I put the configuration file directly into the bin directory here.

Vi mongodb.conf

The contents are as follows:

Port=27017

Dbpath=/workspace/data/mongodb/db

Logappend=true

Fork=true

Logpath=/workspace/log/mongodb/logs

Note that when you turn on the daemon mode fork, be sure to set the log log

When setting up log logs, it is important to note that the path to logpath must be a file path, not a folder path.

4, test start

Enter the bin directory and enter the command

. / mongod-f. / mongodb.conf

At this time, it will show that the database started successfully.

Test it locally on the server and use the command

. / mongo 127.0.0.1

MongoDB shell version: 2.6.4

Connecting to: 127.0.0.1/test

This indicates that the database started successfully

Use tool connections to test other machines in the local area network.

Some partners may find that they cannot connect, usually because the port of the firewall is not open.

Use the command to open the port

Open the port

Firewall-cmd-zone=public-add-port=27017/tcp-permanent

View Port

Firewall-cmd-permanent-query-port=27017/tcp

Restart the firewall

Firewall-cmd-reload

Note:

A, add-- permanent to ensure that it can be opened after reboot.

B, it's better to restart the firewall here. Sometimes opening the port doesn't take effect immediately. I don't know why.

Well, now other machines in the local area network can also connect to the database.

5, register to boot the system

The startup of centos 7 is very different from previous versions of centos. Now replace the previous chkconfig and service commands with the systemctl command

The method to register to boot is as follows:

Create a new startup service for mongodb under the system service directory, and give 754 permissions

Cd / lib/systemd/system

Vi mongodb.service

Chmod 754 mongodb.service

The contents are as follows

[Unit]

Description=mongodb

After=network.target remote-fs.target nss-lookup.target

[Service]

Type=forking

ExecStart=/workspace/app/mongodb/bin/mongod-f / workspace/app/mongodb/bin/mongodb.conf

ExecReload=/bin/kill-s HUP $MAINPID

ExecStop=/workspace/app/mongodb/bin/mongod-- shutdown-f / workspace/app/mongodb/bin/mongodb.conf

PrivateTmp=true

[Install]

WantedBy=multi-user.target

The path must write the absolute path.

Start

Systemctl start mongodb.service

Close

Systemctl stop mongodb.service

Register to boot

Systemctl enable mongodb.service

6. Restart the machine to verify

Reboot
