dpdk-openresty fork from official openresty-1.13.6.2, and run on the dpdk user space TCP/IP stack(ANS). For detail function, please refer to openresty official website(http://http://openresty.org/).

Build and install

---

• Download latest dpdk version from dpdk website

$ make config T=x86_64-native-linuxapp-gcc
$ make install T=x86_64-native-linuxapp-gcc
$ export RTE_SDK=/home/mytest/dpdk
$ export RTE_TARGET=x86_64-native-linuxapp-gcc

• Build dpdk and ANS following the ANS wiki

$ git clone https://github.com/ansyun/dpdk-ans.git
$ export RTE_ANS=/home/mytest/dpdk-ans
$ ./install_deps.sh
$ cd ans
$ make
$ sudo ./build/ans -c 0x2 -n 1  -- -p 0x1 --config="(0,0,1)"

• Download dpdk-openresty, build dpdk-openresty

$ git clone https://github.com/ansyun/dpdk-openresty.git
$ ./configure  --with-http_dav_module
$ make
$ make install   # default install dir is /usr/local/openresty

Testing

---

• Setup DPDK Environment

Refer to Getting Started Guide for Linux

• Startup ANS TCP/IP stack

$ sudo ./build/ans -c 0x2 -n 1  -- -p 0x1 --config="(0,0,1)"
EAL: Detected lcore 0 as core 0 on socket 0
EAL: Detected lcore 1 as core 1 on socket 0

Notes

• Shall use the same gcc version to compile your application.
• ANS tcp stack support reuseport, so can enable openresty reuseport feature, multi openresty can listen on same port.
• proxy_pass is supported.
• In order to improve ANS performance, you shall isolate ANS'lcore from kernel by isolcpus and isolcate interrupt from ANS's lcore by update /proc/irq/default_smp_affinity file.
• You shall include dpdk libs as below way because mempool lib has attribute((constructor, used)) in dpdk-16.07 version, otherwise your application would coredump.
