Purpose

We'll install an OpenVPN client in Linux Ubuntu 18 server. So this server can use OpenVPN client to connect to a vpn network.
Make sure we already have an ovpn file that created in OpenVPN server. Please refer to this page Setup OpenVPN Server in AWS VPC.

Preparation

root@gejoreuy:~# wget -O - https://swupdate.openvpn.net/repos/repo-public.gpg%7C sudo apt-key add -
root@gejoreuy:~# echo "deb http://build.openvpn.net/debian/openvpn/stable $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/openvpn-aptrepo.list
root@gejoreuy:~# apt update

Install OpenVPN Client

Install OpenVPN client : 

root@gejoreuy:~# apt install openvpn

Check and make sure OpenVPN client already installed : 

root@gejoreuy:~# openvpn --version

Start and enable OpenVPN client : 

root@gejoreuy:~# systemctl start openvpn
root@gejoreuy:~# systemctl enable openvpn

Set Client Configuration

We can put the ovpn file in this path (change the source address) : 

root@gejoreuy:~# mv /source/client-name.ovpn /etc/openvpn/client/client-name.ovpn

We also can set secret file to make our vpn client can connect to vpn network automatically without asking password : 

root@gejoreuy:~# vi /etc/openvpn/client/client-secret.scrt

Insert this file with two rows that contain user and password value : 

username
password

Set the file to make only user and root can read it : 

root@gejoreuy:~# chmod go-rw /etc/openvpn/client/client-secret.scrt

Try to Connect to VPN Network

Connect to VON network : 

root@gejoreuy:~# openvpn --config /etc/openvpn/client/client-name.ovpn

Test the conection (change some-vpn-node-address with the real address) : 

root@gejoreuy:~# ping some-vpn-node-address
PING 10.22.73.23 (10.22.73.23) 56(84) bytes of data.

64 bytes from 10.22.73.23: icmp_seq=3 ttl=63 time=272 ms
