Install Rails 6 stack in OpenAnolis Linux

OpenAnolis released as alternative distribute linux of CentOS. After got a server at Aliyun double 11 sales, I try to install my familiar Rails web framework on it.

I start installing the Linux server by do a system upgrade:

sudo yum update -y && sudo reboot

But install htop in Anolis linux is not as easy as CentOS, it’s require enable epel explicitly.

sudo yum config-manager --set-enabled PowerTools
sudo yum update
sudo yum --disablerepo="*" --enablerepo="epel" list available | grep htop
sudo yum --disablerepo="*" --enablerepo="epel" install htop

Install locale

yum install langpacks-en glibc-all-langpacks -y
localectl set-locale LANG=en_US.UTF-8

Create the deployer user

adduser deployer
sudo su - deployer
mkdir .ssh
chmod 700 .ssh
vi .ssh/authorized_keys # and paste your public key
chmod 600 .ssh/authorized_keys

Enable deployer as sudo

sudo su -
cd /etc/sudoers.d/
echo "deployer ALL=(ALL) NOPASSWD:ALL" > 20-deployer-user

Secure the ssh by turn off root and password

sudo tail /etc/ssh/sshd_config

PermitRootLogin no
PasswordAuthentication no
