1. Install varnish stable version 6.0.0 under Debian 9.4:

http://varnish-cache.org/_downloads/varnish-6.0.0.tgz
2. Source installation:
refer to:
http://varnish-cache.org/docs/6.0/installation/install.html#debian-ubuntu
apt-get install \
make \
automake \
autotools-dev \
libedit-dev \
libjemalloc-dev \
libncurses-dev \
libpcre3-dev \
libtool \

CentOS/RedHat :
yum install make automake autoconf libtool libedit-devel jemalloc-devel ncurses-devel python-docutils pcre-devel openssl-devel zlib-devel bzip2-devel
tar xf varnish-6.0.0.tgz
cd varnish-6.0.0/
sh autogen.sh
sh configure
make
make install
Or it can be installed with apt-get:
apt-get install varnish
3. Configuration
Nginx is used as the http server, and the http port is port 80
Copy all the *.vcl files under varnish-6.0.0/etc/ to the /etc/varnish/ directory:
cp -rf ./varnish-6.0.0/etc/* /etc/varnish/
Then copy example.vcl to default.vcl
cp example.vcl default.vcl
Modify default.vcl as follows:
backend default {
.host = "192.168.0.112";
#.host = "127.0.0.1";
.port = "80";
}
Direct .host = "127.0.0.1"; also works
Run the following command to view varnishd help information:
varnishd -?
run:
varnishd -a :6801 -f /etc/varnish/default.vcl -s malloc -l 512M
