版本信息：
Ubuntu16.04
gcc version 5.4.0
pcre-8.31
1.安装pcre
1）下载并解压(cd /usr/local/)
wget https://jaist.dl.sourceforge.net/project/pcre/pcre/8.31/pcre-8.31.tar.gz
tar -xzvf pcre-8.31.tar.gz
2）编译安装
cd pcre-8.31
./configure --prefix=/usr/local/pcre-8.31 #预编译
make && make install
注：这样会提示一大堆东西，没有错就好不要太紧张o_O
2.varnishi编译安装
1）下载解压（cd /usr/local/）
wget http://varnish-cache.org/_downloads/varnish-3.0.2.tgz
/usr/local# gzip -dv varnish-3.0.2.tgz
varnish-3.0.2.tgz: 77.5% -- replaced with varnish-3.0.2.tar
/usr/local# tar xvf varnish-3.0.2.tar
2）编译安装
cd varnish-3.0.2
./autogen.sh #不知道这个是个蛇，不管了，就写上吧O_o
./autogen.sh: 1: ./autogen.sh: automake: not found
WARNING: unable to determine automake version
+ aclocal -I m4
./autogen.sh: 41: ./autogen.sh: aclocal: not found
预编译
./configure --prefix=/usr/local/varnish PKG_CONFIG_PATH=/usr/lib/pkgconfig
编译
make #喔嘈 又是一大堆东西滋滋滋～冒出来，淡定淡定，告诉旁边扫地的阿姨，“坐下，不要慌，正常操作！！”～～
安装
make install
3）查看版本
/usr/local/varnish-3.0.2/sbin# ./varnishd -V
注：这是大写的V喔！
这样就安装成功了！！

以上便是varnish的配置文件的内容！！
4.运行varnish
root@dss:/usr/local/varnish-3.0.2/sbin# ./varnishd -f /usr/local/varnish-3.0.2/etc/default.vcl -T 127.0.0.1:2000 -a 0.0.0.0:80 -s file,/tmp,200M
root@dss:/usr/local/varnish-3.0.2/sbin# ps -ef | grep varnish
root 29572 1523 0 17:22 ? 00:00:00 ./varnishd -f /usr/local/varnish-3.0.2/etc/default.vcl -T 127.0.0.1:2000 -a 0.0.0.0:80 -s file,/tmp,200M
nobody 29573 29572 0 17:22 ? 00:00:00 ./varnishd -f /usr/local/varnish-3.0.2/etc/default.vcl -T 127.0.0.1:2000 -a 0.0.0.0:80 -s file,/tmp,200M
root 29597 7572 0 17:22 pts/2 00:00:00 grep --color=auto varnis
下面是运行时很有可能出现的错误了！！
配置文件参考：http://www.bubuko.com/infodetail-1434528.html(写的很详细了)
注：在配置好varnish的配置文件后，运行失败报下面的错，就是标点符号是中文的缘故把
#代码中有错的，
#第16行第三十一个光标位置 ~符号改为英文
#(‘input‘ Line 22 Pos 26)
# if (req.http.host ～ "^(e)?.nent.com$") {

人人为我，我为人人！！
