编辑:重启后,什么都不起作用,

我正在尝试在 ubuntu 16.04 上安装 varnish,

我读了几篇文章,但都不起作用。从我读到的内容来看,从 ubuntu 15.04 开始,配置 varnish 的方式已经改变(因为 systemd)。

现在我遇到了一个真正混乱的情况,无法工作:


在/etc/default/varnish中:

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

/etc/varnish/default.vcl(通常它指向指向 127.0.0 和端口 8080 的主机,但出于调试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 'ExecStart=/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,user=vcache -F -a :80 -T localhost:6082 -f /etc/varnish/default.vcl -S /etc/varnish/secret -s malloc,256m

/lib/systemd/system/varnish.service:

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

[Install]
WantedBy=multi-user.target

service --status-all | grep varnish

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

之后

sudo service varnish stop
sudo service varnish start

清漆服务没有监听http://127.0.0.1:80/,在重新启动之前,它监听了http://127.0.0.1:6081/但不再工作...我不知道该做什么......




编辑:重启后,什么都不起作用,

如果我做 : systemctl status varnish

如果我 sudo : varnishd -d -f /etc/varnish/default.vcl,那么start一切都会正常……直到我退出 cli


感谢@Gerald Schneider 的回复,问题已解决。我发布了我必须执行的步骤:

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!魔法就在/lib/systemd/system/varnish.service文件中,我发现的其他在线资源让我误以为它在别处,所以要小心在线(过时的)教程!

您还需要更改 systemd 服务定义中的 varnish 启动参数。您可以ExecStart在服务定义文件中编辑以以下内容开头的行:

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

但是,修改此文件的缺点是,它不会在软件包的未来更新中更新。或者,如评论中所建议的,您可以创建一个systemd 放入文件,这是向 systemd 定义添加设置的首选方式。

# 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

在这里您只需添加您想要更改的设置,其他所有内容都将从默认定义文件中加载。

例子:

[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

这是默认线路,请根据需要进行更改

之后,告诉 systemctl 重新加载其配置文件并重新启动服务

sudo systemctl daemon-reload
sudo service varnish restart

Varnish 现在应该监听端口 80。

答案2

请注意,插件应该有一个空的 ExecStart=,否则启动服务时会出错(重复的 ExecStart)

sudo mkdir /etc/systemd/system/varnish.service.d
sudo nano /etc/systemd/system/varnish.service.d/varnishd.conf

[Service]
ExecStart=
ExecStart=/usr/sbin/varnishd -j unix,user=vcache -F -a :80 -T <YOUR WEBSERVER IP>:8081 -f /etc/varnish/default.vcl -S /etc/varnish/secret -s malloc,256m
