我已经与 Apache 一起设置了 Varnish，我没有使用 Hitch 或 Pound，只是使用了 Apache mods 的简单代理配置。
Apache 在 8080 上监听
我的 Varnish 配置：
# Configuration file for varnish
#
# /etc/init.d/varnish expects the variables $DAEMON_OPTS, $NFILES and $MEMLOCK
# to be set from this shell script fragment.
#
# Note: If systemd is installed, this file is obsolete and ignored. Please see
# /usr/share/doc/varnish/examples/varnish.systemd-drop-in.conf
# Should we start varnishd at boot? Set to "no" to disable.
START=yes
# Maximum number of open files (for ulimit -n)
NFILES=131072
# Maximum locked memory size (for ulimit -l)
# Used for locking the shared memory log in memory. If you increase log size,
# you need to increase this number as well
MEMLOCK=82000
# Default varnish instance name is the local nodename. Can be overridden with
# the -n switch, to have more instances on a single server.
# You may need to uncomment this variable for alternatives 1 and 3 below.
# INSTANCE=$(uname -n)
# This file contains 4 alternatives, please use only one.
## Alternative 1, Minimal configuration, no VCL
#
# Listen on port 6081, administration on localhost:6082, and forward to
# content server on localhost:8080. Use a 1GB fixed-size cache file.
#
# This example uses the INSTANCE variable above, which you need to uncomment.
#
# DAEMON_OPTS="-a :80 \
# -T localhost:6082 \
# -b localhost:8080 \
# -u varnish -g varnish \
# -S /etc/varnish/secret \
# -s file,/var/lib/varnish/$INSTANCE/varnish_storage.bin,1G"
f
## Alternative 2, Configuration with VCL
#
# Listen on port 6081, administration on localhost:6082, and forward to
# one content server selected by the vcl file, based on the request.
#
DAEMON_OPTS="-a :80 \
-T localhost:6082 \
-f /etc/varnish/default.vcl \
-S /etc/varnish/secret \
-s malloc,256m"
## Alternative 3, Advanced configuration
#
# This example uses the INSTANCE variable above, which you need to uncomment.
#
# See varnishd(1) for more information.
#
# # Main configuration file. You probably want to change it :)
# VARNISH_VCL_CONF=/etc/varnish/default.vcl
#
# # Default address and port to bind to
# # Blank address means all IPv4 and IPv6 interfaces, otherwise specify
# # a host name, an IPv4 dotted quad, or an IPv6 address in brackets.

#
# # Telnet admin interface listen address and port
# VARNISH_ADMIN_LISTEN_ADDRESS=127.0.0.1

#
# # Cache file location
# VARNISH_STORAGE_FILE=/var/lib/varnish/$INSTANCE/varnish_storage.bin
#
# # Cache file size: in bytes, optionally using k / M / G / T suffix,
# # or in percentage of available disk space using the % suffix.
# VARNISH_STORAGE_SIZE=1G
#
# # File containing administration secret
# VARNISH_SECRET_FILE=/etc/varnish/secret
#
# # Backend storage specification
# VARNISH_STORAGE="file,${VARNISH_STORAGE_FILE},${VARNISH_STORAGE_SIZE}"
#
# # Default TTL used when the backend does not specify one
# VARNISH_TTL=120
#
# # DAEMON_OPTS is used by the init script. If you add or remove options, make
# # sure you update this section, too.
# DAEMON_OPTS="-a ${VARNISH_LISTEN_ADDRESS}:${VARNISH_LISTEN_PORT} \
# -f ${VARNISH_VCL_CONF} \

# -t ${VARNISH_TTL} \
# -S ${VARNISH_SECRET_FILE} \
# -s ${VARNISH_STORAGE}"
#
## Alternative 4, Do It Yourself
#
# DAEMON_OPTS=""
DAEMON_OPTS="-a :80 \
-T localhost:6082 \
-f /etc/varnish/default.vcl \
-S /etc/varnish/secret \

我努力了好几天都没能让它工作，试过 Hitch 但没有用，我也在使用带有 HTTPS 模式的 Cloudflare。
当我通过 cURL 访问端口为 80 的 IP 时，我发现了 Varnish 标头，但除此之外什么也没有。
答案1
我通过让 Apache 专门监听 Varnish 监听的 IP（127.0.0.1:8080）而不仅仅是端口来解决这个问题。
