1. 安装

Use docker、package or source installations to install
第三方仓库 https://pkgs.org/download/haproxy

1.1 use docker

docker run -it --rm haproxy:2.2 haproxy -c -f /usr/local/etc/haproxy/haproxy.cfg
docker run -d --name my-running-haproxy -v /apps/etc/haproxy:/usr/local/etc/haproxy:ro --sysctl net.ipv4.ip_unprivileged_port_start=0 haproxy:2.2
docker run -d --name my-running-haproxy -v /apps/etc/haproxy:/usr/local/etc/haproxy:ro  haproxy:2.2
# Reloading config
docker kill -s HUP my-running-haproxy

1.2 use apt


# apt-get install --no-install-recommends software-properties-common
# add-apt-repository ppa:vbernat/haproxy-2.2
# apt update && apt-cache madison haproxy

# apt-get install haproxy=2.2.\*
# haproxy -v
# haproxy -vv

1.3 source installations

dnf -y install systemd-devel
wget https://www.haproxy.org/download/2.2/src/haproxy-2.2.13.tar.gz
tar xf haproxy-2.2.13.tar.gz -C /usr/local/src
cd /usr/local/src/haproxy-2.2.13/
# less INSTALL
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-5.4.3/src/ LUA_LIB=/usr/local/src/lua-5.4.3/src/
make install PREFIX=/apps/haproxy
ln -s /usr/local/src/haproxy-2.2.13/haproxy /usr/sbin/
# haproxy -v
# haproxy -vv

PS: 升级lua到5.4.3

yum install gcc readline-devel systemd-devel
# apt install gcc iproute2 ntpdate tcpdump telnet traceroute nfs-kernel-server nfs-common lrzsz tree openssl libssl-dev libpcre3 libpcre3-dev zlib1g-dev openssh-server libreadline-dev libsystemd-dev
# apt install lua5.3=5.3.3

curl -R -O http://www.lua.org/ftp/lua-5.4.3.tar.gz
tar zxf lua-5.4.3.tar.gz -C /usr/local/src
cd lua-5.4.3/
make all test

2. 基本服务配置

http://cbonte.github.io/haproxy-dconv/2.2/configuration.html

2.1 使用systemctl配置管理

0 root@centos7:~# cat /usr/lib/systemd/system/haproxy.service
[Unit]
Description=HAProxy Load Balancer
After=syslog.target network.target

[Service]
ExecStart=/usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /var/lib/haproxy/haproxy.pid
ExecReload=/bin/kill -USR2 $MAINPID
KillMode=mixed

[Install]
WantedBy=multi-user.target

# systemctl daemon-reload
# systemctl start haproxy

2.2 haproxy.cfg

#---------------------------------------------------------------------
global
    # to have these messages end up in /var/log/haproxy.log you will
    # need to:
    #
    # 1) configure syslog to accept network log events.  This is done
    #    by adding the ‘-r‘ option to the SYSLOGD_OPTIONS in
    #    /etc/sysconfig/syslog
    #
    # 2) configure local2 events to go to the /var/log/haproxy.log
    #   file. A line like the following can be added to
    #   /etc/sysconfig/syslog
    #
    #    local2.*                       /var/log/haproxy.log
