1：準(zhǔn)備編譯安裝HAProxy的基礎(chǔ)環(huán)境
apt install make gcc build-essential libssl-dev zlib1g-dev libpcre3 libpcre3-dev libsystemd-dev libreadline-dev -y
2：編譯安裝lua，為HAProxy支持基于其實(shí)現(xiàn)功能擴(kuò)展。
注：HAProxy要求的lua最低版本為5.3
2.1 下載并且安裝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 查看編譯后的版本
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.編譯安裝haproxy
3.1安裝基礎(chǔ)環(huán)境
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
3.2 解壓并安裝
20210622的下載地址? ?wget? https://www.haproxy.org/download/2.3/src/haproxy-2.3.10.tar.gz
cd /usr/local/src/
tar xf haproxy-2.3.10.tar.gz
cd haproxy-2.3.10
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
注意路徑 /apps/haproxy

3.3 查看編譯安裝好的版本信息
4.編寫haproxy啟動(dòng)腳本
#創(chuàng)建文件
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 -q
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：編寫配置文件
mkdir /etc/haproxy
#創(chuàng)建haproxy的配置文件
vim? /etc/haproxy/haproxy.cfg
global
? ? maxconn 100000
? ? chroot /apps/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 300000ms
? ? timeout client 300000ms
? ? timeout server 300000ms
listen stats
? ? mode http
? ? bind 0.0.0.0:9999
? ? stats enable
? ? log global
? ? stats uri? /haproxy-status
? ? stats auth admin:molson
6:啟動(dòng)haproxy
groupadd haproxy
useradd -g haproxy haproxy
#創(chuàng)建文件并授權(quán)
mkdir? /var/lib/haproxy? ? #相關(guān)文件存放位置
chown? 99.99 /var/lib/haproxy/ -R
#啟動(dòng)Haproxy并設(shè)置開機(jī)啟動(dòng)及檢查Haproxy的狀態(tài)
systemctl?unmask haproxy
systemctl? start haproxy
systemctl? enable haproxy
systemctl? status? haproxy
7：打開網(wǎng)頁驗(yàn)證狀態(tài)
