1、为了解决这个问题，修改varnish配置文件如下:
1.用 root 用户打开:
CentOS 6: /etc/sysconfig/varnish
CentOS 7: /etc/varnish/varnish.params
Ubuntu: /etc/default/varnish
2、搜索 http_resp_hdr_len 参数
3、如果参数不存在增加 thread_pool_max
4、设置 http_resp_hdr_len
示例:-p http_resp_hdr_len=64000 \
代码片段:
# DAEMON_OPTS is used by the init script.
DAEMON_OPTS="-a ${VARNISH_LISTEN_ADDRESS}:${VARNISH_LISTEN_PORT} \
-f ${VARNISH_VCL_CONF} \
-T ${VARNISH_ADMIN_LISTEN_ADDRESS}:${VARNISH_ADMIN_LISTEN_PORT} \
-p thread_pool_min=${VARNISH_MIN_THREADS} \
-p thread_pool_max=${VARNISH_MAX_THREADS} \ -p http_resp_hdr_len=64000 \
-S ${VARNISH_SECRET_FILE} \
-s ${VARNISH_STORAGE}"
