brew link --overwrite --force node@14

• 安装软件 #

  1、官网旧版本Formula

  gdb example

  # ref from: https://stackoverflow.com/questions/62785290/installing-previous-versions-of-a-formula-with-brew-extract
  
  # TAP=...     # <org>/<repo>, for example "my-org/homebrew-old"
  # MODULE=...  # name of module you want to install, e.g. "hugo"
  # VERS=...    # version of $MODULE you want to install, e.g., "0.80.0"
  
  brew tap-new 12302/gdb
  # 在最新的仓库中提取原来的版本到新建的tap.
  brew extract --version 13.1 gdb 12302/gdb
  # 运行安装命令（其实这个时候已经可以通过 brew search gdb 搜索到需要安装版本的软件了）
  brew install 12302/gdb/gdb@13.1
  

  

  2、自定义仓库

  brew安装

  # 修改了 max-connection-per-server from 16 to 128,
  # 参考： https://ntsd.dev/aria2-max-connections-per-server/
  brew tap xhsgg12302/aria2 https://github.com/xhsgg12302/aria2.git
  brew extract --version 1.36.0 aria2 xhsgg12302/aria2
  # tar -czvf aria2.tar.gz aria2
  # readlink -f aria2.tar.gz
  # 计算sha256值
  shasum -a 256 aria2-1.36.0.tar.xz
  brew install xhsgg12302/aria2/aria2@1.36.0 --verbose --debug --build-from-source
  
  # 使用原生的下载,即使使用128个单机并发，最多16个连接数
  /usr/local/Cellar/aria2/1.36.0_2/bin/aria2c -s128 -k20M https://releases.ubuntu.com/22.04/ubuntu-22.04.2-desktop-amd64.iso
  # 但是使用重新编译过后的,最大连接数可以达到128，至于速度问题，可能和当前网络环境，以及服务器带宽有关系。
  # 这种针对服务器网络单个连接差的很有效。多起线程，聚少成多。
  aria2c -s128 -k20M https://releases.ubuntu.com/22.04/ubuntu-22.04.2-desktop-amd64.iso
  

  ubuntu安装

  # Ubuntu20.04 install aria2c from source code
  git clone https://github.com/aria2/aria2.git
  cd aria2
  vim src/OptionHandlerFactory.cc
      OptionHandler* op(new NumberOptionHandler(PREF_MAX_CONNECTION_PER_SERVER,
                                              TEXT_MAX_CONNECTION_PER_SERVER,
                                              "1", 1, 128, 'x'));
  mkdir build && cd build
  autoreconf -i
  sudo apt-get install libssl-dev libssh2-1-dev
  ../configure --disable-dependency-tracking  --prefix=/usr/local --with-libssh2 --without-gnutls --without-libgmp --without-libnettle --without-libgcrypt --without-appletls --with-openssl
  aria2c -h
