Haproxy TCP数据转发

时间：2025-05-10 09:07:14

在实际项目中需要用到haproxy做TCP转发，下面主要针对haproxy的安装及TCP数据转发配置进行说明

一、安装Haproxy

(1)编译安装Haproxy

mkdir -p /data01/haproxy

tar -zxvf haproxy-1.7.1.tar.gz

cd haproxy-1.7.1

make TARGET=linux26 ARCH=x86_64 PREFIX=/data01/haproxy

make install PREFIX=/data01/haproxy

mkdir /data01/haproxy/conf

mkdir /data01/haproxy/lib

mkdir /data01/haproxy/run

mkdir /data01/haproxy/logs

cp haproxy.cfg /data01/haproxy/conf/

(2)修改Haproxy配置

vi /etc/syslog.conf

local1.*  /data01/haproxy/logs/haproxy.log

local0.*  /data01/haproxy/logs/haproxy.log

vi /etc/rsyslog.d/haproxy.conf

local1.*  /data01/haproxy/logs/haproxy.log

local0.*  /data01/haproxy/logs/haproxy.log

vi /etc/sysconfig/syslog

SYSLOGD_OPTIONS="-r -m 0"

servie rsyslog restart

(3)启动haproxy

sbin/haproxy -f conf/haproxy.cfg
sbin/haproxy -f -d conf/haproxy.cfg   #检查哪些服务启动OK

二、Haproxy TCP数据转发

global

   log  127.0.0.1 local0

   log  127.0.0.1 local1 notice

   ulimit-n  40960

   maxconn 4000

   pidfile /data01/haproxy/run/haproxy.pid

   user XXX

   nbproc 2

   daemon

defaults

    mode   tcp

    option  redispatch

    option  abortonclose

    retries  3

    timeout  http-request  300s

    timeout  queue         1m

    timeout  connect      300s

    timeout client            1m

    timeout server           1m

    timeout http-keep-alive 300s

    timeout check            300s

    maxconn                     4096

listen stats

    bind     *:9093

    balance roundrobin

    mode     tcp

    server s1  XXX:5000   weight 1
