haproxy 1.8.3 编译安装

1、安装必要的包

yum install gcc gcc-c++ glibc glibc-devel pcre pcre-devel openssl openssl-devel systemd-devel net-tools vim iotop bc zip unzip zlib-devel lrzsz tree screen lsof tcpdump wget ntpdate

2、关闭selinux 和防火墙：

systemctl status firewalld

systemctl stop  firewalld

systemctl disable firewalld

3、tar xf haproxy-1.8.13.tar.gz   -C /usr/local/src/

cd haproxy-1.8.13;

注释：USE_CPU_AFFINITY=1 为开启haproxy 进程与cpu核心绑定，

USE_SYSTEMD=1 为支持使用 -Ws systemd-aware master-worker 模式，启动haproxy

make ARCH=x86_64 TARGET=linux2628 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 USE_SYSTEMD=1 USE_CPU_AFFINITY=1 PREFIX=/usr/local/haproxy

​mkde install  PREFIX=/usr/local/haproxy
