Install Mikrotik CHR on CentOS 7

Guide to installing Mikrotik CHR on CentOS 7. In this tutorial using Mikrotik CHR 6.48.7.

1. You must install CentOS 7 first.

2. Login SSH as root.

5. If it's correct, we continue.

vi /mnt/rw/autorun.scr

Then fill it in with this:

$ ADDRESS=`ip addr show eth0 | grep global | cut -d' ' -f 6 | head -n 1` && \
GATEWAY=`ip route list | grep default | cut -d' ' -f 3` && \
echo "/ip address add address=$ADDRESS interface=[/interface ethernet find where name=ether1]
/ip route add gateway=$GATEWAY
/ip dns set servers=,"

6. Make sure this autorun.scr is correct as we have typed it before.

cat /mnt/rw/autorun.scr

echo u > /proc/sysrq-trigger
dd if=chr-6.48.7.img bs=1024 of=/dev/vda
