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！！

3.编辑配置文件

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)

#代码中有错的，
#第16行第三十一个光标位置 ~符号改为英文
