Make sure you've read ["Prepare Your System"](https://mailcow.github.io/mailcow-dockerized-docs/prerequisite-system) before proceeding!
|
|
|
|
|
|
You need Docker and Docker Compose.
|
|
|
|
**1\.** Learn how to install [Docker](https://docs.docker.com/engine/installation/linux/) and [Docker Compose](https://docs.docker.com/compose/install/).
|
|
|
|
Quick installation for most operation systems:
|
|
|
|
- Docker
|
|
```
|
|
curl -sSL https://get.docker.com/ | CHANNEL=stable sh
|
|
# After the installation process is finished, you may need to enable the service and make sure it is started (e.g. CentOS 7)
|
|
systemctl enable docker.service
|
|
systemctl start docker.service
|
|
```
|
|
|
|
- Docker-Compose
|
|
```
|
|
curl -L https://github.com/docker/compose/releases/download/$(curl -Ls https://www.servercow.de/docker-compose/latest.php)/docker-compose-$(uname -s)-$(uname -m) > /usr/local/bin/docker-compose
|
|
chmod +x /usr/local/bin/docker-compose
|
|
```
|
|
|
|
Please use the latest Docker engine available and do not use the engine that ships with your distros repository.
|
|
|
|
**2\.** Clone the master branch of the repository, make sure your umask equals 0022.
|
|
```
|
|
# umask
|
|
0022
|
|
# cd /opt
|
|
# git clone https://github.com/mailcow/mailcow-dockerized
|
|
# cd mailcow-dockerized
|
|
```
|
|
|
|
**3\.** Generate a configuration file. Use a FQDN (`host.domain.tld`) as hostname when asked.
|
|
```
|
|
./generate_config.sh
|
|
```
|
|
|
|
**4\.** Change configuration if you want or need to.
|
|
```
|
|
nano mailcow.conf
|
|
```
|
|
If you plan to use a reverse proxy, you can, for example, bind HTTPS to 127.0.0.1 on port 8443 and HTTP to 127.0.0.1 on port 8080.
|
|
|
|
You may need to stop an existing pre-installed MTA which blocks port 25/tcp. See [this chapter](https://mailcow.github.io/mailcow-dockerized-docs/firststeps-local_mta/) to learn how to reconfigure Postfix to run besides mailcow after a successful installation.
|
|
|
|
**4\.1\.** OpenStack users and users with a MTU not equal to 1500:
|
|
|
|
Edit `docker-compose.yml` and change the network settings according to your MTU.
|
|
Add the new driver_opts parameter like this:
|
|
```
|
|
networks:
|
|
mailcow-network:
|
|
...
|
|
driver_opts:
|
|
com.docker.network.driver.mtu: 1450
|
|
...
|
|
```
|
|
|
|
**5\.** Pull the images and run the composer file. The parameter `-d` will start mailcow: dockerized detached:
|
|
```
|
|
docker-compose pull
|
|
docker-compose up -d
|
|
```
|
|
|
|
Done!
|
|
|
|
You can now access **https://${MAILCOW_HOSTNAME}** with the default credentials `admin` + password `moohoo`.
|
|
|
|
The database will be initialized right after a connection to MySQL can be established.
