Ubuntu 16.04
varnishd（清漆-4.1.8修订版d266ac5c6）
我正在读The Varnish书。
我做了这个练习： http://book.varnish-software.com/4.0/chapters/Getting_Started.html#exercise-configure-varnish
即：“请参阅表2并找到安装的Varnish配置文件。打开并编辑该文件以侦听端口80上的客户端请求，并在端口1234上具有管理接口”。
现在我有：
清漆
DAEMON_OPTS="-a :80 \
-T localhost:1234 \
-f /etc/varnish/default.vcl \
-S /etc/varnish/secret \
-s malloc,256m"
default.vcl
vcl 4.0;
backend default {
.host = "127.0.0.1";
.port = "8080";
}
然后我尽我所能在“运动：配置清漆”中做了必要的事。
至少，我已经重新开始了：
service varnish restart
我来到下一个练习： http://book.varnish-software.com/4.0/chapters/Getting_Started.html#vcl-reload
$ sudo service varnish reload
Job for varnish.service failed because the control process exited with error code. See "systemctl status varnish.service" and "journalctl -xe" for details.

好吧，连接失败（localhost：1234）:( null） 但我似乎已经跟着这本书了。
当我手动尝试时：
$ varnishadm -T localhost:1234
Connection failed (localhost:1234): (null)
我检查了端口是否被占用：netstat -nlpt
该端口是免费的。
你能帮我一把吗？
