Varnish 删除 $HTTP_HOST

Varnish 删除 $HTTP_HOST

我遇到了 varnish 的问题,它会删除 HTTP_HOST 变量。我的设置是 nginx ->(5 个服务器中的 1 个:) varnish -> 本地 nginx -> php5-fpm。我正在运行多个网站,但没有Host它,只会显示默认网站。

/etc/varnish/默认.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.

    if (req.url ~ "\.(css|js|png|gif|jp(e)?g)") {
        unset req.http.cookie;

/etc/默认/清漆

# 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# Note: If systemd is installed, this file is obsolete and ignored.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 \

#            -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 \

## Alternative 4, Do It Yourself
#
# DAEMON_OPTS=""

更新:没有清漆一切工作正常,但速度较慢。

答案1

这是有道理的。

如果您有多个站点,则需要定义多个后端,并有条件地连接到每个站点。

目前,您唯一的后端是 127.0.0.1,它通常会访问 Nginx 中的默认站点。

请参阅这个答案以了解如何做到这一点 -https://stackoverflow.com/a/3373251/1463157
