mydpdkdns

dns server with high performance, based on dpdk.

Documentation

Please refer to http://dpdk.org/doc.

Install dpdk

tar xf dpdk-17.02.1.tar.xz -C /root
cd /root
mv dpdk-17.02.1 dpdk
cd dpdk

make config T=x86_64-native-linuxapp-gcc
make
make install T=x86_64-native-linuxapp-gcc

Set environment

edit .profile or .bashrc, add the following:

export RTE_SDK=/root/dpdk
export RTE_TARGET=x86_64-native-linuxapp-gcc

Usage

# git clone https://github.com/alandtsang/mydpdkdns.git
# cd mydpdkdns/tools

record eth info

# ./recordeth.sh eth0

It will record the eth0 information to ethinfo file.

If recordeth.sh fails to execute, you need to manually create ethinfo.

e.g.

DEV=eth0
IPADDR=192.168.44.129
NETMADK=255.255.255.0
MAC=08:00:27:cf:bb:76
GATEWAY=192.168.44.2

insert modules and mount hugetlbfs

# ./preparedpdk.sh eth0

It will bind eth0 to DPDK.

start program

# ./start.sh

configure IP and MAC addresses

upeth.sh will read the nic information in the ethinfo, and then configure IP and MAC address for vEth0.

# ./upeth.sh
APP: Configure network interface of 0 up

Now, you can test the dns server.

stop program

# ./stop.sh

unbind dpdk

# ./unbind.sh
