Installing Red on CentOS 7
For safety reasons, DO NOT install Red with a root user. If you are unsure how to create a new user on Linux, see DigitalOcean’s tutorial: How To Create a New Sudo-enabled User.
Installing the pre-requirements
Install the pre-requirements with yum:
sudo yum -y groupinstall development sudo yum -y install gcc zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel openssl-devel tk-devel libffi-devel xz-devel java-11-openjdk-headless nano git
In order to install gcc 8, we’ll use SCL repository:
sudo yum -y install centos-release-scl sudo yum -y install devtoolset-8-gcc devtoolset-8-gcc-c++ echo "source scl_source enable devtoolset-8" >> ~/.bashrc source ~/.bashrc
In order to install Git 2.11 or greater, we recommend adding the IUS repository:
sudo yum -y install https://repo.ius.io/ius-release-el7.rpm sudo yum -y swap git git236
Installing Python with pyenv
On distributions where Python 3.9 needs to be compiled from source, we recommend the use of pyenv. This simplifies the compilation process and has the added bonus of simplifying setting up Red in a virtual environment.
To install/update pyenv, run the following command:
command -v pyenv && pyenv update || curl https://pyenv.run | bash
After this command, you will see a warning about ‘pyenv’ not being in the load path. To address this, you should run these commands:
profile=$([ -n "$ZSH_VERSION" ] && echo ~/.zprofile || ([ -f ~/.bash_profile ] && echo ~/.bash_profile || echo ~/.profile)) rcfile=$([ -n "$ZSH_VERSION" ] && echo ~/.zshrc || echo ~/.bashrc) printf '%s\n%s\n%s\n' 'export PYENV_ROOT="$HOME/.pyenv"' 'export PATH="$PYENV_ROOT/bin:$PATH"' "$([ -f "$profile" ] && cat "$profile")" > "$profile" echo 'eval "$(pyenv init --path)"' >> "$profile" echo 'eval "$(pyenv init -)"' >> "$rcfile" echo 'eval "$(pyenv virtualenv-init -)"' >> "$rcfile"
Then log out and log back in and run the following command:
CONFIGURE_OPTS=--enable-optimizations pyenv install 3.9.18 -v
This may take a long time to complete, depending on your hardware. For some machines (such as
Raspberry Pis and micro-tier VPSes), it may take over an hour; in this case, you may wish to remove
CONFIGURE_OPTS=--enable-optimizations part from the front of the command, which will
drastically reduce the install time. However, be aware that this will make Python run about 10%
After that is finished, run:
pyenv global 3.9.18
Pyenv is now installed and your system should be configured to run Python 3.9.
Creating a Virtual Environment
If you want to learn more about virtual environments, see page: About Virtual Environments
We require installing Red into a virtual environment. Don’t be scared, it’s very straightforward.
pyenv virtualenv saves you the headache of remembering where you installed your virtual
environments. This option is only available if you installed Python with pyenv.
First, ensure your pyenv interpreter is set to python 3.8.1 or greater with the following command:
Now, create a virtual environment with the following command:
pyenv virtualenv <name>
<name> with whatever you like. If you ever forget what you named it,
you can always use the command
pyenv versions to list all virtual environments.
Now activate your virtualenv with the following command:
pyenv shell <name>
You must activate the virtual environment with the above command every time you open a new
shell to run, install or update Red. You can check out other commands like
pyenv local and
pyenv global if you wish to keep the virtualenv activated all the time.
Choose one of the following commands to install Red.
To install without additional config backend support:
python -m pip install -U pip wheel python -m pip install -U Red-DiscordBot
Or, to install with PostgreSQL support:
python -m pip install -U pip wheel python -m pip install -U "Red-DiscordBot[postgres]"
Setting Up and Running Red
After installation, set up your instance with the following command:
This will set the location where data will be stored, as well as your storage backend and the name of the instance (which will be used for running the bot).
Once done setting up the instance, run the following command to run Red:
redbot <your instance name>
It will walk through the initial setup, asking for your token and a prefix. You can find out how to obtain a token with this guide.
If it’s the first time you’re using Red, you should check our Getting started guide that will walk you through all essential information on how to interact with Red.
