安装依赖
yum install -y gcc pcre pcre-devel openssl openssl-devel
创建依赖账号，并禁止账号登录
useradd -M -s /sbin/nologin -u 1000 haproxy
编译安装haproxy
cd /usr/local/src/
wget https://www.haproxy.org/download/1.7/src/haproxy-1.7.11.tar.gz
tar xf haproxy-1.7.11.tar.gz
cd haproxy-1.7.11/
make TARGET=linux2628 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 PREFIX=/usr/local/haproxy
make install PREFIX=/usr/local/haproxy
/usr/local/haproxy/sbin/haproxy -v
复制haproxy启动脚本到启动目录下
cp /usr/local/src/haproxy-1.7.11/haproxy /usr/sbin/
cp /usr/local/src/haproxy-1.7.11/haproxy-systemd-wrapper /usr/sbin
配置成systemctl可以管理
