创建用户并安装依赖包
# selinux会影响haproxy启动,会有'cannot bind UNIX socket (Permission denied)'的报错，请关闭它除非你知道设置selinux规则
sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config
setenforce 0
groupadd -r haproxy
useradd -r -g haproxy -s /sbin/nologin -d /var/lib/haproxy -c "haproxy" haproxy
mkdir /var/lib/haproxy
chown -Rf haproxy:haproxy /var/lib/haproxy
yum install make gcc gcc-c++ openssl openssl-devel pcre pcre-devel systemd systemd-devel -y
下载安装包并安装
curl -LO https://www.haproxy.org/download/2.6/src/haproxy-2.6.6.tar.gz
tar -zxf haproxy-2.6.6.tar.gz && cd haproxy-2.6.6
# 编译以及安装参数请查看'haproxy-2.6.6/Makefile'
make TARGET=linux-glic USE_OPENSSL=1 USE_EPOLL=1 USE_PROMEX=1 USE_SYSTEMD=1
make install PREFIX=/etc/haproxy SBINDIR=/sbin MANDIR=/usr/share/man DOCDIR=/usr/share/doc
- USE_PROMEX=1： 开启 Prometheus exporter
- USE_SYSTEMD=1: 使用systemd管理服务
