Ubuntu系统安装和运行n2n

(使用root权限)

下载git

apt install git

下载n2n源码

git clone /meyerd/n2n.git

下载完成之后，当前目录下会出现名为n2n的文件夹：

root@VM-0-15-ubuntu:~# ll n2ntotal 28drwxr-xr-x 5 root root 4096 Jun 23 15:33 ./drwxrwxrwx 21 ubuntu ubuntu 4096 Jun 23 15:33 ../drwxr-xr-x 8 root root 4096 Jun 23 15:33 .git/-rw-r--r-- 1 root root 189 Jun 23 15:33 .gitignoredrwxr-xr-x 6 root root 4096 Jun 23 15:33 n2n_v1/drwxr-xr-x 9 root root 4096 Jun 23 15:33 n2n_v2/-rw-r--r-- 1 root root 783 Jun 23 15:33 README.md

n2n文件夹中同时包含了n2n_v1和n2n_v2两个文件夹。使用cmake编译n2n_v2。

编译安装n2n

安装cmake

n2n_v2的CMakeLists.txt指明cmake最低版本要求是2.6：

root@VM-0-15-ubuntu:~/n2n# more ./n2n_v2/CMakeLists.txtproject(n2n)cmake_minimum_required(VERSION 2.6)# N2n informationset(N2N_VERSION 2.1.0)set(N2N_OSNAME ${CMAKE_SYSTEM})（以下省略）

安装cmake，指定版本不低于2.6

apt install cmake>=2.6

查看cmake版本

root@VM-0-15-ubuntu:~/n2n# cmake --versioncmake version 3.10.2CMake suite maintained and supported by Kitware (/cmake).

编译、安装

cd n2nmkdir -p build_n2n_v2 #创建一个build文件夹，专门用于存放编译生成的文件和目录，#如Makefile、CMakeCache.txt、CMakeFiles#cmake_install.cmake、可执行文件等cd build_n2n_v2cmake ../n2n_v2 #cmakemake && make install #编译、安装
