Brief introduction

MongoDB provides officially supported packages in its own repository. This repository contains the following packages:

(1) mongodb-org: one metapackage, the following four component packages will be installed automatically.

(2) mongodb-org-server: contains the mongod daemon, associated init script and configuration file (/ etc/mongod.conf). You can use the initialization script to start with the mongod configuration file. By default / etc/mongod.conf, the configuration file provided by the package has been set to 127.0.0.1 by bind_ip. Before initializing the replica set, modify this setting according to your environment needs.

(3) mongodb-org-mongos: contains mongos daemons.

(4) mongodb-org-shell: contains mongoshell.

(5) mongodb-org-tools: some extensions

1. System environment:

1. System version

CentOS Linux release 7.4.1708 (Core)

1. Recommended yum source [set source according to version]

Vim / etc/yum.repos.d/mongodb-org-4.0.repo

[mongodb-org-4.0]

Name = MongoDB Repository

Baseurl = https://repo.mongodb.org/yum/redhat/7/mongodb-org/4.0/x86_64/

Gpgcheck = 1

Enabled = 1

Gpgkey = https://www.mongodb.org/static/pgp/server-4.0.asc

The version of MongoDB is earlier than 4.0.

[mongodb-org-3.6]

Name = MongoDB Repository

Baseurl = https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.6/x86_64/

Gpgcheck = 1

Enabled = 1

Gpgkey = https://www.mongodb.org/static/pgp/server-3.6.asc

Keep in mind that odd-numbered versions (e.g. 3.5) are development versions and are not suitable for production

2. Install MongoDB software package

Method 1: install the latest stable version of MongoDB

[root@edu-mycat-01 yum.repos.d] # yum install-y mongodb-org

Method 2: install a specific version of MongoDB, specify each component package separately and append the version number to the package name, as shown in the following example:

[root@edu-mycat-01 yum.repos.d] # yum install-y mongodb-org-3.7.3 mongodb-org-server-3.7.3 mongodb-org-shell-3.7.3 mongodb-org-mongos-3.7.3 mongodb-org-tools-3.7.3

You can specify any available version of MongoDB. However, yum, when a newer version is available, will upgrade the package. In order to prevent accidental upgrade, please nail the package. To fix the wrapper, add the following exclude directive to your / etc/yum.conf file:

Exclude = mongodb-org,mongodb-org-server,mongodb-org-shell,mongodb-org-mongos,mongodb-org-tools

3. SELinux settings (permissive mode is used here)

Permission is required if enabled: semanage port-a-t mongod_port_t-p tcp 27017

The MongoDB instance stores its data file / var/lib/mongo and its log file / var/log/mongodb by default and runs using the mongod user account. You can specify alternate log and data file directories / etc/mongod.conf in

4. Mongodb service

1) start

[root@edu-mycat-01 mongo] # systemctl start mongod

2) restart

[root@edu-mycat-01 mongo] # systemctl restart mongod

3) close

[root@edu-mycat-01 mongo] # systemctl stop mongod

4) View command

5. Use MongoDB

[root@edu-mycat-01 mongo] # mongo-- host 127.0.0.1 purl 27017

6. Uninstall MongoDB Community
