流量回放goreplay

本文主要是介绍流量回放goreplay，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1.网关权重\mirror旁路 (生产)

2.goreplay编译测试

<==============================
/usr/local/go/pkg/tool/linux_amd64/link: running gcc failed: exit status 1
/bin/ld: cannot find -lpthread
/bin/ld: cannot find -lc
===============================>
yum install glibc-static.x86_64 -y
<==============================
# github.com/google/gopacket/pcap
vendor/github.com/google/gopacket/pcap/pcap_unix.go:34:18: fatal error: pcap.h: No such file or directory
===============================>
https://www.tcpdump.org/#source
libpcap-1.10.1.tar.gz
./configure
make
make install
<==============================
git clone https://github.com/buger/goreplay.git
cd goreplay
make build
======================================

1.libpcap数据包
https://www.cnblogs.com/10087622blog/p/8320234.html 2.goreplay
--input-raw-engine "libpcap"
如果http request数据包大于一定值，丢弃--input-raw-override-snaplen 
65536+200nohup ./gor --input-raw :4438  --output-http "" --http-allow-header host:.*xxx.*  --input-raw-override-snaplen  --output-http-elasticsearch http://username:123456@xxx:9200/goreplay_record  > gor.log.80 2>&1 &
