debian varnish service is masked 解决办法

https://www.yangshengliang.com/kaiyuan-shijie/linux-shijie/1133.html

不要使用 sudo 进行 install varnish，使用普通用户权限即可

ubuntu 18.04下安装 Varnish 4.0.3-5 版本

参考如下设置，先配置 deb 的软件仓库

https://packagecloud.io/varnishcache/varnish40/install#manual-deb

如果是按照如下脚本后的执行配置可能不对

curl -s https://packagecloud.io/install/repositories/varnishcache/varnish40/script.deb.sh | sudo bash

需要修改在/etc/apt/sources.list.d/varnishcache_varnish40.list下的配置如下，区别主要在于 ubuntu 的软件版本号设置的不对，不应该设置为当前的ubuntu版本(bionic)，否则会出现找不到安装包的问题，设置为trusty就可以

12.04 LTS Precise Pangolin	ubuntu/precise
14.04 LTS Trusty  Tahr	    ubuntu/trusty
16.04 LTS Xenial Xerus	    ubuntu/xenial
18.04 LTS Bionic Beaver	    ubuntu/bionic

注意如下的ubuntu 和 trusty
