/e/ Cloud Services installation on CentOS 7
The installation instructions for ecloud-selfhosting refer to installation on Ubuntu. My laptop runs Fedora and my server OS of choice is CentOS, which are closely related RPM based distros. So I decided to try installing the services on CentOS and see how it goes. It was reasonably straight forward, here are the steps I took:
# Step 1: set up DNS records on your chosen domain per the standard installation instructions, and PTR for reverse DNS resolution
# bootstrap script uses a git argument not present in the old version of git in the CentOS repo. We'll use this 3rd party repo to install git 2.
yum -y install https://centos7.iuscommunity.org/ius-release.rpm
# EPEL repo has certbot, among other useful packages
yum -y install epel-release
# Install Docker yum repo to get the newest version of Docker
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
# Install dependencies
yum -y install git2u-all salt-minion bind-utils certbot
# bootstrap script expects these to be in place. NextCloud seems to have UID 33 hard-coded for the www-data user/group, so we have to set that explicitly.
mkdir /etc/salt/minion.d
groupadd -g 33 www-data
adduser -u 33 -g 33 www-data
# Install and start Docker
yum -y install docker-ce docker-compose
systemctl enable docker
systemctl start docker
# Disable and stop Postfix SMTP server which is running by default
systemctl disable postfix
systemctl stop postfix
# Check that ports 25, 80, 110, 143, 443, 587, 993, 995 are open in the firewall (HTTP ports required for Let's Encrypt SSL cert domain control validation!). Set in /etc/sysconfig/iptables or use firewall-cmd depending on the firewall you have enabled.
# Grab bootstrap-generic.sh and run it
wget https://gitlab.e.foundation/e/infra/bootstrap/raw/master/bootstrap-generic.sh
bash bootstrap-generic.sh https://gitlab.e.foundation/e/infra/ecloud-selfhosting
# Ignore the apt-get command not found warning, we already installed required deps from yum.
Once you have completed the bootstrap script, you should receive a welcome email with instructions to finish setting up your first mailbox, along with admin logins for nextcloud, rspamd and Postfix.Admin. Setup of my /e/ phone, Thunderbird and Nextcloud account in Fedora worked flawlessly first time.
