环境

OS:Ubuntu1804
haproxy: http://www.haproxy.org/download/2.0/src/haproxy-2.0.4.tar.gz
lua:http://www.lua.org/ftp/lua-5.3.5.tar.gz
IP:192.168.7.182

安装步骤

1.准备编译安装HAProxy的基础环境
# apt install make gcc build-essential libssl-dev zlib1g-dev libpcre3 libpcre3-dev libsystemd-dev libreadline-dev -y

2.编译安装lua，为HAProxy支持基于其实现功能扩展。
注：HAProxy要求的lua最低版本为5.3
2.1 下载并且安装lua
# wget -P /usr/local/src/ http://www.lua.org/ftp/lua-5.3.5.tar.gz
# cd /usr/local/src/
# tar xf lua-5.3.5.tar.gz
# cd lua-5.3.5/src/
# make linux
2.2 查看编译后的版本
# ./lua -v
Lua 5.3.5  Copyright (C) 1994-2018 Lua.org, PUC-Rio

3.编译安装haproxy
3.1 解压并安装
# cd /usr/local/src/
# tar xf haproxy-2.0.4.tar.gz
# cd haproxy-2.0.4
# make -j `lscpu |awk 'NR==4{print $2}'` ARCH=x86_64 TARGET=linux-glibc USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 USE_SYSTEMD=1 USE_CPU_AFFINITY=1 USE_LUA=1 LUA_INC=/usr/local/src/lua-5.3.5/src/ LUA_LIB=/usr/local/src/lua-5.3.5/src/ PREFIX=/apps/haproxy && make install PREFIX=/apps/haproxy
3.2 查看编译安装好的版本信息
# ./haproxy -v
HA-Proxy version 2.0.4 2019/08/06 - https://haproxy.org/

4.编写haproxy启动脚本
# cat > /lib/systemd/system/haproxy.service << EOF                
[Unit]
Description=HAProxy Load Balancer
After=syslog.target network.target

[Service]
ExecStartPre=/apps/haproxy/sbin/haproxy -f /etc/haproxy/haproxy.cfg -c
ExecStart=/apps/haproxy/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /var/lib/haproxy/haproxy.pid
ExecReload=/bin/kill -USR2 \$MAINPID

[Install]
WantedBy=multi-user.target
EOF

5.编写配置文件/etc/haproxy/haproxy.cfg
# mkdir /etc/haproxy
# cat > /etc/haproxy/haproxy.cfg << EOF
global
    maxconn 100000
    chroot /usr/local/haproxy
    stats socket /var/lib/haproxy/haproxy.sock mode 600 level admin
    uid 99
    gid 99
    daemon
    pidfile /var/lib/haproxy/haproxy.pid
    log 127.0.0.1 local3 info

defaults
    option http-keep-alive
    option forwardfor
    maxconn 100000
    mode http
    timeout connect 300s
    timeout client  300s
    timeout server  300s

listen stats
    bind  :9009
    stats enable
    stats uri /status
    stats auth admin:123456
    stats realm HAPorxy\ Stats\ Page
EOF

6.创建相关目录
# mkdir /var/lib/haproxy
# mkdir /usr/local/haproxy
# chown 99.99 /var/lib/haproxy/ -R

7.启动并设为开机自启动和查看haproxy状态
# systemctl enable --now haproxy
# systemctl status haproxy
