OpenWrt logo

OpenWrt Project is a Linux operating system targeting embedded devices. Instead
of trying to create a single, static firmware, OpenWrt provides a fully
writable filesystem with package management. This frees you from the
application selection and configuration provided by the vendor and allows you
to customize the device through the use of packages to suit any application.
For developers, OpenWrt is the framework to build an application without having
to build a complete firmware around it; for users this means the ability for
full customization, to use the device in ways never envisioned.

Sunshine!

Development

To build your own firmware you need a GNU/Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack of a
case sensitive file system.

Requirements

You need the following tools to compile OpenWrt, the package names vary between
distributions. A complete list with distribution specific packages is found in
the Build System Setup
documentation.

1
2
binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.6+ rsync subversion unzip which

Quickstart

  1. Run ./scripts/feeds update -a to obtain all the latest package definitions
    defined in feeds.conf / feeds.conf.default

  2. Run ./scripts/feeds install -a to install symlinks for all obtained
    packages into package/feeds/

  3. Run make menuconfig to select your preferred configuration for the
    toolchain, target system & firmware packages.

  4. Run make to build your firmware. This will download all sources, build the
    cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen
    applications for your target system.

The main repository uses multiple sub-repositories to manage packages of
different categories. All packages are installed via the OpenWrt package
manager called opkg. If you’re looking to develop the web interface or port
packages to OpenWrt, please find the fitting repository below.

Ubuntu 16.04 install shadowsocks

1.1更新apt

apt update &&apt upgrade

##1.2安装python pip 

apt install python-pip python-dev

##1.3升级pip到9.0版本

pip install -U pip

###如果pip报错

Traceback (most recent call last):
  File "/usr/lib/python2.7/runpy.py", line 174, in _run_module_as_main
    "__main__", fname, loader, pkg_name)
  File "/usr/lib/python2.7/runpy.py", line 72, in _run_code
    exec code in run_globals
  File "/usr/lib/python2.7/dist-packages/pip/__main__.py", line 19, in 
    sys.exit(pip.main())
  File "/usr/lib/python2.7/dist-packages/pip/__init__.py", line 215, in main
    locale.setlocale(locale.LC_ALL, '')
  File "/usr/lib/python2.7/locale.py", line 581, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting

则需要设置locale环境变量

export LC_ALL=C

如果还报错则需要安装

apt install libssl-dev -y
apt install libffi-dev

##2.1安装shdowsocks

pip install shadowsocks

添加shadowsocks 配置文件

mkdir /config &&
mkdir /config/shadowsocks

echo "{\"server\":\"服务器IP\",\"server_port\":端口号,\"password\":\"密码\",\"timeout\":300,\"method\":\"aes-256-cfb\",\"fast_open\":true,\"workers\":1}" > /config/shadowsocks/shadowsocks.json

添加自启,将

sudo ssserver -c /config/shadowsocks/shadowsocks.json -d start

添加到 /etc/rc.local exit 0 的前面

wget http://people.redhat.com/~rjones/virt-what/files/virt-what-1.18.tar.gz

cd virt-what-1.18/

#centos 6.x 安装nodejs

##1.安装g++ 4.9.4 以上版本

  • 1.1需要安装gcc-c++老版本 

    yum -y install make clang clang++ gcc gcc-c++;

    不然编译时会报错:

    make[2]: *** [all-stage1-target-libgcc] 错误 2
make[2]: Leaving directory '/gcc-4.9.4/gcc-build'
make[1]: *** [stage1-bubble] 错误 2
make[1]: Leaving directory '/gcc-4.9.4/gcc-build'
make: *** [all] 错误 2

  • 1.2下载gcc 4.9.4 

    wget http://ftp.gnu.org/gnu/gcc/gcc-4.9.4/gcc-4.9.4.tar.bz2 &&tar -xf gcc-4.9.4.tar.bz2 &&cd gcc-4.9.4 &&./contrib/download_prerequisites

  • 1.3 生成编译目录

    mkdir gcc-build && cd gcc-build

  • 1.4 生成makefile

    ../configure --enable-checking=release --enable-languages=c,c++ --disable-multilib

  • 1.5 编译（注意：此步骤非常耗时，搬瓦工单核我用了大约30分钟）

    make
//如果是多核服务器请加上 -j4 会快一些

  • 1.6 安装

    make install 
//如果安装失败 请加上sudo权限
//成功后验证版本
gcc -v

##2.安装nodejs最新版本

  • 2.1 下载nodejs code

    wget https://nodejs.org/dist/v8.9.4/node-v8.9.4.tar.gz && tar -xf node-v8.9.4.tar.gz &&cd node-v8.9.4

  • 2.2 开始安装

    ./configure --coverage &&make coverage &&make install
//如果失败 需要加上sudo
