ubuntu – varnish守护程序不监听已配置的端口

我正在尝试在ubuntu 16.04上安装varnish,

我看过几篇文章都没有.
从我读到的,自ubuntu 15.04以来,配置清漆的方式已经改变(因为systemd).

现在,我有一个真正的混乱,不起作用：

/ etc / default / varnish：

DAEMON_OPTS="-a :80 \
             -T localhost:6082 \
             -f /etc/varnish/default.vcl \
             -S /etc/varnish/secret \
             -s malloc,256m"

/etc/varnish/default.vcl(通常它指向一个指向127.0.0和端口8080的主机,但出于debuging目的我将其修改为外部域)
vcl 4.0;

# Default backend deFinition. Set this to point to your content server.
backend default {
    .host = "www.varnish-cache.org"; 
    .port = "80";
}

/etc/apache2/ports.conf

Listen 8080

grep -R’ExcStart = /usr/sbin / varnishd’/ etc /

/etc/systemd/system/varnish.service:ExecStart=/usr/sbin/varnishd -j unix,user=vcache -F -a :80 -T localhost:6082 -f /etc/varnish/default.vcl -S /etc/varnish/secret -s malloc,256m
/etc/systemd/system/varnish.service.d/customexec.conf:ExecStart=/usr/sbin/varnishd -a :80 -T localhost:6082 -f /etc/varnish/default.vcl -S /etc/varnish/secret -s malloc,256m
/etc/systemd/system/multi-user.target.wants/varnish.service:ExecStart=/usr/sbin/varnishd -j unix,256m

/lib/systemd/system/varnish.service：

GNU nano 2.5.3                                                Fichier: /lib/systemd/system/varnish.service

服务–status-all | grep清漆

[ - ]  varnish
 [ + ]  varnishlog
 [ + ]  varnishncsa

之后

sudo service varnish stop
sudo service varnish start

清漆服务没有在http://127.0.0.1:80/上监听,在重新启动之前,它会在http://127.0.0.1:6081/上收听,但它不再工作……我不知道知道该做些什么……

编辑：重启后,没有任何作用,

如果我做 ：
systemctl状态清漆

如果我sudo：varnishd -d -f /etc/varnish/default.vcl,然后开始,一切正常……直到我退出cli

感谢@Gerald Schneider的回应.我发布了我必须做的步骤：

sudo apt remove varnish
sudo apt-get purge varnish
# I manually remove the 3 files in created in /etc/systemd/system/*
sudo apt install varnish
sudo nano /lib/systemd/system/varnish.service # put the rigth conf
sudo nano /etc/varnish/default.vcl #put the rigth conf
sudo systemctl daemon-reload
sudo service varnish restart

一切正常！
魔术在/lib/systemd/system/varnish.service文件中,我发现的其他在线资源让我认为它在其他地方,所以要小心在线(过时的)教程！

sudo vi /lib/systemd/system/varnish.service

# create the drop in directory
sudo mkdir /etc/systemd/system/varnish.service.d
# create the drop in file. The name is irrelevant,as long as it ends in .conf
sudo vi /etc/systemd/system/varnish.service.d/mysettings.conf

[Service]
ExecStart=/usr/sbin/varnishd -j unix,256m

sudo systemctl daemon-reload
sudo service varnish restart
