Ich habe ein Problem mit Varnish, das die HTTP_HOST-Variable entfernt. Mein Setup ist nginx -> (1 von 5 Servern mit:) Varnish -> lokales nginx -> php5-fpm. Ich betreibe mehrere Sites, aber ohne HostVarnish wird nur die Standardsite angezeigt.
/etc/varnish/default.vcl
# This is a basic VCL configuration file for varnish. See the vcl(7)
# man page for details on VCL syntax and semantics.

# server.

.host = "127.0.0.1";
.port = "81";
}

# redefine any of these subroutines, the built-in logic will be
# appended to your code.

# set req.http.x-host = req.http.host;
# set req.http.x-url = req.url;

/etc/Standard/Lack
# Configuration file for varnish
#
# /etc/init.d/varnish expects the variables $DAEMON_OPTS, $NFILES and $MEMLOCK
# to be set from this shell script fragment.
#
# Note: If systemd is installed, this file is obsolete and ignored. You will
# need to copy /lib/systemd/system/varnish.service to /etc/systemd/system/ and
# edit that file.
# Should we start varnishd at boot? Set to "no" to disable.
START=yes
# Maximum number of open files (for ulimit -n)
NFILES=131072
# Maximum locked memory size (for ulimit -l)
# Used for locking the shared memory log in memory. If you increase log size,
# you need to increase this number as well
MEMLOCK=82000
# Default varnish instance name is the local nodename. Can be overridden with
# the -n switch, to have more instances on a single server.
# You may need to uncomment this variable for alternatives 1 and 3 below.
# INSTANCE=$(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 :6081 \
# -T localhost:6082 \
# -b localhost:8080 \
# -u varnish -g varnish \
# -S /etc/varnish/secret \
# -s file,/var/lib/varnish/$INSTANCE/varnish_storage.bin,1G"
## 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 \
-t 120 \
-w 8,36,120 \
-f /etc/varnish/default.vcl \
-S /etc/varnish/secret \
-s malloc,2048m"
## 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.

# VARNISH_THREAD_TIMEOUT=120
#
# # Cache file location

#
# # 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 ${VARNISH_ADMIN_LISTEN_ADDRESS}:${VARNISH_ADMIN_LISTEN_PORT} \
# -t ${VARNISH_TTL} \
# -w ${VARNISH_MIN_THREADS},${VARNISH_MAX_THREADS},${VARNISH_THREAD_TIMEOUT} \
# -S ${VARNISH_SECRET_FILE} \
# -s ${VARNISH_STORAGE}"
#
## Alternative 4, Do It Yourself
#
# DAEMON_OPTS=""
UPD: Ohne Lack funktioniert alles richtig, aber langsam.
Antwort1
Das macht Sinn.
Wenn Sie mehrere Sites haben, müssen Sie mehrere Backends definieren und bedingt eine Verbindung zu jedem herstellen.
Im Moment ist Ihr einziges Backend 127.0.0.1, das im Allgemeinen Ihre Standardsite in Nginx erreicht.
