# Prerequisites
|
|
|
|
To install Matrix services using this Ansible playbook, you need:
|
|
|
|
- (Recommended) An **x86** server ([What kind of server specs do I need?](faq.md#what-kind-of-server-specs-do-i-need)) running one of these operating systems:
|
|
- **CentOS** (7 only for now; [8 is not yet supported](https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/300))
|
|
- **Debian** (9/Stretch or newer)
|
|
- **Ubuntu** (18.04 or newer, although [20.04 may be problematic](ansible.md#supported-ansible-versions))
|
|
- **Archlinux**
|
|
|
|
Generally, newer is better. We only strive to support released stable versions of distributions, not betas or pre-releases. This playbook can take over your whole server or co-exist with other services that you have there.
|
|
|
|
This playbook somewhat supports running on non-`amd64` architectures like ARM. See [Alternative Architectures](alternative-architectures.md).
|
|
|
|
If your distro runs within an [LXC container](https://linuxcontainers.org/), you may hit [this issue](https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/703). It can be worked around, if absolutely necessary, but we suggest that you avoid running from within an LXC container.
|
|
|
|
- `root` access to your server (or a user capable of elevating to `root` via `sudo`).
|
|
|
|
- [Python](https://www.python.org/) being installed on the server. Most distributions install Python by default, but some don't (e.g. Ubuntu 18.04) and require manual installation (something like `apt-get install python3`). On some distros, Ansible may incorrectly [detect the Python version](https://docs.ansible.com/ansible/latest/reference_appendices/interpreter_discovery.html) (2 vs 3) and you may need to explicitly specify the interpreter path in `inventory/hosts` during installation (e.g. `ansible_python_interpreter=/usr/bin/python3`)
|
|
|
|
- The [Ansible](http://ansible.com/) program being installed on your own computer. It's used to run this playbook and configures your server for you. Take a look at [our guide about Ansible](ansible.md) for more information, as well as [version requirements](ansible.md#supported-ansible-versions) and alternative ways to run Ansible.
|
|
|
|
- An HTTPS-capable web server at the base domain name (`<your-domain>`) which is capable of serving static files. Unless you decide to [Serve the base domain from the Matrix server](configuring-playbook-base-domain-serving.md) or alternatively, to use DNS SRV records for [Server Delegation](howto-server-delegation.md).
|
|
|
|
- Properly configured DNS records for `<your-domain>` (details in [Configuring DNS](configuring-dns.md)).
|
|
|
|
- Some TCP/UDP ports open. This playbook configures the server's internal firewall for you. In most cases, you don't need to do anything special. But **if your server is running behind another firewall**, you'd need to open these ports:
|
|
|
|
- `80/tcp`: HTTP webserver
|
|
- `443/tcp`: HTTPS webserver
|
|
- `3478/tcp`: TURN over TCP (used by Coturn)
|
|
- `3478/udp`: TURN over UDP (used by Coturn)
|
|
- `5349/tcp`: TURN over TCP (used by Coturn)
|
|
- `5349/udp`: TURN over UDP (used by Coturn)
|
|
- `8448/tcp`: Matrix Federation API HTTPS webserver. In some cases, this **may necessary even with federation disabled**. Integration Servers (like Dimension) and Identity Servers (like ma1sd) may need to access `openid` APIs on the federation port.
|
|
- the range `49152-49172/udp`: TURN over UDP
|
|
- potentially some other ports, depending on the additional (non-default) services that you enable in the **configuring the playbook** step (later on). Consult each service's documentation page in `docs/` for that.

When ready to proceed, continue with [Configuring DNS](configuring-dns.md).
