Haproxy TCP数据转发

Posted 2020-09-09 异想天开

   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
