起步：Tor源码编译

Tor快速编译脚本：

运行环境：Debian 9/Ubuntu 19.04

1. 安装依赖

安装make

sudo apt-get install make

安装gcc与g++

sudo apt-get install gcc
sudo apt-get install g++

安装 openssl

sudo apt-get install openssl

安装 zlib
首先要先装 ruby

sudo apt-get install ruby
sudo apt-get install zlib1g
sudo apt-get install zlib1g-dev

安装 libevent(异步通信库)

sudo apt-get install libevent-dev

安装 OpenSSL

sudo apt-get install libssl-dev

2. 编译 Tor 源码

进入https://www.torproject.org/download/download.html.en下载 stable 的 tor 源码。

或使用git clone https://git.torproject.org/tor.git获取源码。

tor 官方仓库：[https://gitweb.torproject.org/tor.git]()

wget https://www.torproject.org/dist/tor-0.3.4.8.tar.gz
tar -zxvf tor-0.3.4.8.tar.gz
cd tor-0.3.4.8
./configure
make

此处如果无法运行./configure

阅读根目录的INSTALL：

If you got the source from git, run ./autogen.sh, which will
run the various auto* programs. Then you can run ./configure, and
refer to the above instructions.

./autogen.sh

# 上面命令如果报错
sudo apt-get install automake
sudo apt-get install autoconf

如果有以下报错：

==================================

Building Tor has failed since manpages cannot be built.

You need asciidoc installed to be able to build the manpages.
To build without manpages, use the --disable-asciidoc argument
when calling configure.

==================================

则在configure后添加--disable-asciidoc即可

./configure --disable-asciidoc

其实可以从编译的顺序看出 Tor 的文件调用关系

make install并运行 tor：

root@localhost:~/tor# make install
make[1]: Entering directory '/root/tor'
 /usr/bin/mkdir -p '/usr/local/bin'
  /usr/bin/install -c src/or/tor src/tools/tor-resolve src/tools/tor-gencert '/usr/local/bin'
 /usr/bin/mkdir -p '/usr/local/bin'
 /usr/bin/install -c contrib/client-tools/torify '/usr/local/bin'
 /usr/bin/mkdir -p '/usr/local/etc/tor'
 /usr/bin/install -c -m 644 src/config/torrc.sample '/usr/local/etc/tor'
 /usr/bin/mkdir -p '/usr/local/share/tor'
 /usr/bin/install -c -m 644 src/config/geoip src/config/geoip6 '/usr/local/share/tor'
make[1]: Leaving directory '/root/tor'
# 然后直接运行tor即可
root@localhost:~/tor# tor

从上面的make install过程可以看出，系统会把配置文件torrc.sample拷贝到/usr/local/etc/tor下。

出现如下信息则运行成功：
