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.
3. Start installing the required package:
yum install wget unzip -y
wget https://download.mikrotik.com/routeros/6.48.7/chr-6.48.7.img.zip -O chr.img.zip
unzip chr.img.zip
mount -o loop,offset=512 chr-6.48.7.img /mnt
4. Check /mnt if it is mounted correctly.
ls /mnt
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=8.8.8.8,1.1.1.1"
6. Make sure this autorun.scr is correct as we have typed it before.
cat /mnt/rw/autorun.scr
7. The final process is triger, write to disk, and reboot.
echo u > /proc/sysrq-trigger
dd if=chr-6.48.7.img bs=1024 of=/dev/vda
reboot
8. For the final verification step, you can download WInBox on the official Mikrotik page: https://mikrotik.com/download
