Copy files with rsync – Ingo's Blog

I have to setup and configure a DEV server and afterwards the QA/staging and PROD servers.

I will download required software with my laptop and upload to DEV server into folder /app/files. For other servers I just want to copy this folder from the DEV server.

Setup server

DEV

# install software
yum install rsync -y

# create user
adduser myUser

# create folder
mkdir /app/files
chown myUser:myUser /app/files

# switch to myUser
su myUser

# Create Private & Public keys
ssh-keygen -t rsa -b 4096            # generates id_rsa & id_rsa.pub in  /home/myUser/.ssh/

# authorize yourself
cat /home/myUser/.ssh/id_rsa.pub >> /home/myUser/.ssh/authorized_keys
chmod 0600 ~/.ssh/authorized_keys

QA / others

nearly the same setup, but we copy the keys from the DEV user, as he is the same as on the other servers.

# install software
yum install rsync -y

# create user
adduser myUser

# create folder
mkdir /app/files
chown myUser:myUser /app/files

# switch to myUser
su myUser

# create .ssh folder
mkdir ~/.ssh
chmod 0700 ~/.ssh

# create files, copy content from DEV server!
vi ~/.ssh/id_rsa
chmod 0600 ~/.ssh/id_rsa
vi ~/.ssh/id_rsa.pub
chmod 0600 ~/.ssh/id_rsa.pub
vi ~/.ssh/authorized_keys
chmod 0600 ~/.ssh/authorized_keys

Test SSH login

# login from DEV to QA
[myUser@DEV] ssh QA
# login from QA to DEV
[myUser@QA] ssh DEV

# loggin with explicit port
[myUser@DEV] ssh QA -p 22
