环境:
haproxy: https://www.haproxy.org/download/2.0/src/haproxy-2.0.29.tar.gz
OS:Ubuntu1804.3
lua: http://www.lua.org/ftp/lua-5.4.4.tar.gz
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
# cd /usr/local/src/
# cd wget http://www.lua.org/ftp/lua-5.4.4.tar.gz
# tar xf lua-5.4.4.tar.gz
# cd lua-5.4.4/src/
# make all test
2.2 查看编译后的版本
# ./lua -v
Lua 5.4.4Copyright (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-2.0.29.tar.gz
# cd haproxy-2.0.29
# make 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-5.4.4/src/ LUA_LIB=/usr/local/src/lua-5.4.4/src/ PREFIX=/apps/haproxy
3.2 查看编译安装好的版本信息
# ./haproxy -v
HA-Proxy version 2.0.29-5e15b0f 2022/05/13 – https://haproxy.org/
4.编写haproxy启动脚本
# vim /lib/systemd/system/haproxy.service
[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
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 :9999
stats enable
stats uri /status
stats auth admin:123456
6.创建相关目录
# mkdir /var/lib/haproxy
# mkdir /usr/local/haproxy
# mkdir /etc/haproxy
# chown 99.99 /var/lib/haproxy/ -R
# chown 99.99 /usr/local/haproxy -R
7.启动并设为开机自启动和查看haproxy状态
# systemctl daemon-reload
# systemctl enable –now haproxy
# systemctl status haproxy
[root@ubuntu-template ~ ]#systemctl status haproxy
