在已有Apache站点的服务器上设置Discourse

[AstonJ]

对于 HTTPS，请查看我最新的配置文件：

global
	#
	# 上传至：/etc/haproxy/
	#
  # 若要让这些消息最终出现在 /var/log/haproxy.log 中，您需要：
  #
  # 1) 配置 syslog 以接受网络日志事件。这可以通过在
  #    /etc/sysconfig/syslog 中的 SYSLOGD_OPTIONS 添加 '-r' 选项来实现
  #
  # 2) 配置 local2 事件输出到 /var/log/haproxy.log 文件。可以在
  #    /etc/sysconfig/syslog 中添加如下行：
  #
  #    local2.*                       /var/log/haproxy.log
  #
  # log         127.0.0.1 local2
