关闭防火墙selinux
systemctl stop firewalld && setenforce 0
RS安装httpd启动服务，修改index网页内容方便验证
[root@RS1 ~]# yum -y install httpd
[root@RS1 ~]# systemctl enable --now httpd
[root@RS1 ~]# echo RS1> /var/www/html/index.html
[root@RS2 ~]# yum -y install httpd
[root@RS2 ~]# systemctl enable --now httpd
[root@RS2 ~]# echo RS2> /var/www/html/index.html
[root@DR ~]# tar xf haproxy-2.3.0.tar.gz
[root@DR ~]# cd haproxy-2.3.0/
[root@DR haproxy-2.3.0]# yum -y install gcc pcre-devel bzip2-devel openssl-devel systemd-devel
[root@DR haproxy-2.3.0]# useradd -r -M -s /sbin/nologin haproxy
查看安装相关配置的文档
[root@DR haproxy-2.3.0]# less INSTALL
编译并安装
//确保环境纯净
[root@DR haproxy-2.3.0]# make clean
//-j 多核加速编译
[root@DR haproxy-2.3.0]# make -j $(nproc) TARGET=linux-glibc USE_OPENSSL=1 USE_ZLIB=1 USE_PCRE=1 USE_SYSTEMD=1
//make install指定安装目录
[root@DR haproxy-2.3.0]# make install PREFIX=/usr/local/haproxy
//复制命令到sbin下
[root@DR haproxy]# cp sbin/haproxy /usr/sbin/
内核参数配置
//启用ip转发和非本地ip绑定（不在网卡配置文件，直接在配置文件写入修改）
[root@DR haproxy]# echo ‘net.ipv4.ip_forward = 1‘>> /etc/sysctl.conf
[root@DR haproxy]# echo ‘net.ipv4.ip_nonlocal_bind = 1‘>> /etc/sysctl.conf
[root@DR haproxy]# sysctl -p
net.ipv4.ip_forward = 1
net.ipv4.ip_nonlocal_bind = 1
生成haproxy配置文件
//生成配置保存目录
[root@DR haproxy]# mkdir /etc/haproxy
//查看配置说明文档
[root@DR haproxy-2.3.0]# less doc/configuration.txt
//写入配置文件
[root@DR haproxy-2.3.0]# vim /etc/haproxy/haproxy.cfg
[root@DR ~]# cat /etc/haproxy/haproxy.cfg
