I. Basic concepts

Package Management on Operating Systems

Debian/Ubuntu Package Management

Advanced Packaging Tool – APT

apt-get is a command line tool for interacting with the Advanced Package Tool (APT) library (a package management system for Linux distributions). It allows you to search for, install, manage, update, and remove software.

Configuration of the APT system repositories is stored in the /etc/apt/sources.list file and the /etc/apt/sources.list.d directory. You can add additional repositories in a separate file in the /etc/apt/sources.list.d directory, for example, redis.list, docker.list.

dpkg

dpkg is a package manager for Debian-based systems. It can install, remove, and build packages, but unlike other package management systems, it cannot automatically download and install packages – or their dependencies. APT and Aptitude are newer, and layer additional features on top of dpkg.

# install
sudo dpkg -i package_file.deb
# uninstall
sudo apt-get remove package_name

CentOS/RHEL Package Management

Yellow Dog Updater, Modified (YUM)

YUM is the primary package management tool for installing, updating, removing, and managing software packages in Red Hat Enterprise Linux. YUM performs dependency resolution when installing, updating, and removing software packages. YUM can manage packages from installed repositories in the system or from .rpm packages. The main configuration file for YUM is at /etc/yum.conf, and all the repos are at /etc/yum.repos.d.

# add repos config to /etc/yum.repos.d
...
# clear repo cache
yum clean all
# create repo cache
yum makecache

# search package
yum search {package_name}

# upgrade package
yum update

# install package
yum install {package_name}

# uninstall package
yum remove {package_name}

RPM (RPM Package Manager)

RPM is a popular package management tool in Red Hat Enterprise Linux-based distros. Using RPM, you can install, uninstall, and query individual software packages. Still, it cannot manage dependency resolution like YUM. RPM does provide you useful output, including a list of required packages. An RPM package consists of an archive of files and metadata. Metadata includes helper scripts, file attributes, and information about packages.

# install
sudo rpm -i package_file.rpm
sudo rpm --install package_file.rpm
# reinstall
sudo rpm --reinstall package_file.rpm
# uninstall
sudo rpm -e package_name
sudo rpm --erase package_name

Redis

Linux

Install from Snapcraft

The Snapcraft store provides Redis packages that can be installed on platforms that support snap. Snap is supported and available on most major Linux distributions.

1	sudo snap install redis

If your Linux does not currently have snap installed, install it using the instructions described in Installing snapd.

Debian/Ubuntu/Deepin

Install from the official APT repositories

1 2	sudo apt-get update sudo apt-get install redis-server

Update config

1	sudo vim /etc/redis/redis.conf

Uncomment the following line

1	# supervised auto

1	supervised auto

Enable and restart Redis service

1 2	sudo systemctl enable redis.service sudo systemctl restart redis.service

Verify

1 2	systemctl status redis redis-cli ping

Install from the Redis APT repository

Most major Linux distributions provide packages for Redis.

1 2	# prerequisites sudo apt install lsb-release curl gpg

# add the repository to the apt index, update it. and then install redis. 

curl -fsSL https://packages.redis.io/gpg | sudo gpg --dearmor -o /usr/share/keyrings/redis-archive-keyring.gpg

echo "deb [signed-by=/usr/share/keyrings/redis-archive-keyring.gpg] https://packages.redis.io/deb $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/redis.list

sudo apt-get update
sudo apt-get install redis

# verify
systemctl status redis
redis-cli ping

1
sudo yum install redis
Start Redis:
1
sudo systemctl start redis
Optional: To automatically start Redis on boot:
1
sudo systemctl enable redis

Verify the Installation

If Redis is running, it will return:

PONG

Windows

Redis is not officially supported on Windows.

Install from Source

Supported Operating Systems

All Linux distros (distributions)
MacOS

You can compile and install Redis from source on variety of platforms and operating systems including Linux and macOS. Redis has no dependencies other than a C compiler and libc.

# Download source files
wget https://download.redis.io/redis-stable.tar.gz
# Compiling
tar -xzvf redis-stable.tar.gz
cd redis-stable
make
# make sure the build is correct
make test

If the compile succeeds, you’ll find several Redis binaries in the src directory, including:

redis-server: the Redis Server itself
redis-cli is the command line interface utility to talk with Redis.

Starting and stopping Redis

cd redis-stable
# starting redis server
./src/redis-server &
# starting redis server with config
./src/redis-server redis.conf &
# stopping redis server
ps -ef | grep redis-server | awk '{print $2}' | head -1 | xargs kill -9
# connect to redis
./src/redis-cli
# auth
127.0.0.1:6379> auth YOUR_PASSWORD

update password in redis.conf

1	# requirepass foobared

1	requirepass YOUR_STRONG_PASSWORD

Manage Redis service using systemd

Create the /etc/systemd/system/redis.service file, and add the following line to the file

[Unit]
Description=Redis
After=network.target

[Service]
ExecStart=/usr/local/bin/redis-server /etc/redis/redis.conf
ExecStop=/usr/local/bin/redis-cli shutdown
Restart=always

[Install]
WantedBy=multi-user.target

copy the files

cd /path/to/redis/source/dir
sudo mkdir /etc/redis
sudo cp redis.conf /etc/redis/
sudo cp src/redis-server /usr/local/bin/
sudo cp src/redis-cli /usr/local/bin/

Edit config

1	sudo vim /etc/redis/redis.conf

Uncomment the following line

1	# supervised auto

1	supervised auto

Enable and start Redis service

1
2
3

systemctl enable redis
systemctl start redis
systemctl status redis

To verify Redis is up and running, run the following command:

1	redis-cli PING

MySQL

Linux

Windows

Elasticsearch

Kibana

CentOS/RHEL

Install from the elastic YUM repository

Download and install the public signing key:

1	rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch

Create a file called kibana.repo in the /etc/yum.repos.d/ directory for RedHat based distributions, or in the /etc/zypp/repos.d/ directory for OpenSuSE based distributions, containing:

[kibana-8.x]
name=Kibana repository for 8.x packages
baseurl=https://artifacts.elastic.co/packages/8.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

You can now install Kibana with one of the following commands:

# older Red Hat based distributions
sudo yum install kibana
# Fedora and other newer Red Hat distributions
sudo dnf install kibana
# OpenSUSE based distributions
sudo zypper install kibana

Install by downloading RPM file

Downloading the Kibana RPM file

wget https://artifacts.elastic.co/downloads/kibana/kibana-8.8.2-x86_64.rpm
wget https://artifacts.elastic.co/downloads/kibana/kibana-8.8.2-x86_64.rpm.sha512
shasum -a 512 -c kibana-8.8.2-x86_64.rpm.sha512 
sudo rpm --install kibana-8.8.2-x86_64.rpm

Start Elasticsearch and generate an enrollment token for Kibana

When you start Elasticsearch for the first time, the following security configuration occurs automatically:

Authentication and authorization are enabled, and a password is generated for the elastic built-in superuser.
Certificates and keys for TLS are generated for the transport and HTTP layer, and TLS is enabled and configured with these keys and certificates.

The password and certificate and keys are output to your terminal.

Run Kibana with systemd

To configure Kibana to start automatically when the system starts, run the following commands:

1 2	sudo /bin/systemctl daemon-reload sudo /bin/systemctl enable kibana.service

Kibana can be started and stopped as follows:

1 2	sudo systemctl start kibana.service sudo systemctl stop kibana.service

Log information can be accessed via journalctl -u kibana.service.

Configure Kibana via the config file

Kibana loads its configuration from the /etc/kibana/kibana.yml file by default. The format of this config file is explained in Configuring Kibana.
