HAProxy安装及haproxy.cfg配置项说明

一、源码编译安装haproxy 2.x，配置服务启动脚本。

1、下载Haproxy源码包

wget -c https://repo.huaweicloud.com/haproxy/2.4/src/haproxy-2.4.8.tar.gz

2、下载源码编译工具

yum install -y gcc gcc-c++ make

3、下载Haproxy依赖包lua并编译安装

curl -R -O http://www.lua.org/ftp/lua-5.4.4.tar.gz
tar zxf lua-5.4.4.tar.gz -C /usr/local/src/
cd /usr/local/src/lua-5.4.4
make linux test

4、解压Haproxy源码包

tar xf haproxy-2.4.8.tar.gz -C /usr/local/src/
cd /usr/local/src/haproxy-2.4.8

5、安装编译时需要的依赖包

yum install openssl-devel pcre-devel systemd-devel -y

6、编译安装Haproxy

make ARCH=x86_64 TARGET=linux-glibc USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 USE_SYSTEMD=1 USE_LUA=1 LUA_INC=/usr/local/src/lua-5.4.4/src/ LUA_LIB=/usr/local/src/lua-5.4.4/src/
make install PREFIX=/usr/local/haproxy
