1：准备编译安装HAProxy的基础环境
1 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
1 wget -P /usr/local/src/ http://www.lua.org/ftp/lua-5.3.5.tar.gz 2 cd /usr/local/src/ 3 tar xf lua-5.3.5.tar.gz 4 cd lua-5.3.5/src/ 5 make linux
2.2 查看编译后的版本
root@template-ubuntu-20200606:/usr/local/src/lua-5.3.5/src# ./lua -v Lua 5.3.5 Copyright (C) 1994-2018 Lua.org, PUC-Rio
3.编译安装haproxy
3.1安装基础环境
1 root@template-ubuntu-20200606:/usr/local/src# apt install iproute2 ntpdate tcpdump telnet traceroute nfs-kernel-server nfs-common lrzsz tree openssl libssl-dev libpcre3 libpcre3-dev zlib1g-dev gcc openssh-server iotop unzip libreadline-dev libsystemd-dev
3.3 解压并安装
1 cd /usr/local/src/ 2 tar xf haproxy-2.0.4.tar.gz 3 cd haproxy-2.0.4 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
3.3 查看编译安装好的版本信息
1 root@template-ubuntu-20200606:/usr/local/src/haproxy-2.0.12# ./haproxy -v 2 HA-Proxy version 2.0.12 2019/12/21 - https://haproxy.org/
4.编写haproxy启动脚本
1 #创建文件 2 vim /lib/systemd/system/haproxy.service 3 4 [Unit] 5 Description=HAProxy Load Balancer 6 After=syslog.target network.target 7 8 [Service] 9 ExecStartPre=/apps/haproxy/sbin/haproxy -f /etc/haproxy/haproxy.cfg -c -q 10 ExecStart=/apps/haproxy/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /var/lib/haproxy/haproxy.pid 11 ExecReload=/bin/kill -USR2 $MAINPID 12 13 [Install] 14 WantedBy=multi-user.target
5：编写配置文件
1 #创建haproxy的配置文件 2 3 vim /etc/haproxy/haproxy.cfg 4 5 global 6 maxconn 100000 7 chroot /apps/haproxy 8 stats socket /var/lib/haproxy/haproxy.sock mode 600 level admin 9 uid 99 10 gid 99 11 daemon 12 pidfile /var/lib/haproxy/haproxy.pid 13 log 127.0.0.1 local3 info 14 15 16 defaults 17 option http-keep-alive 18 option forwardfor 19 maxconn 100000 20 mode http 21 timeout connect 300000ms 22 timeout client 300000ms 23 timeout server 300000ms 24 25 26 listen stats 27 mode http 28 bind 0.0.0.0:9999 29 stats enable 30 log global 31 stats uri /haproxy-status 32 stats auth admin:molson
6:启动haproxy
1 #创建文件并授权 2 mkdir /var/lib/haproxy #相关文件存放位置 3 chown 99.99 /var/lib/haproxy/ -R 4 5 6 #启动Haproxy并设置开机启动及检查Haproxy的状态 7 systemctl start haproxy 8 systemctl enable haproxy 9 systemctl status haproxy
7：打开网页验证状态
看到如上图的信息，说明Haproxy安装成功
