linux非root用戶下安裝軟件，搭建生產環境

以前的用實驗室的服務器，由於某些緣由，使用的用戶沒有root權限。linux的非root用戶不少軟件沒法安裝，很是的不方便。個人方法是使用brew來代替系統的包管理工具。brew是最早用在mac上的包管理工具，能夠將全部的包託管在user本地的環境內。下面的文檔中運行的時候記得將用戶名改爲本身的。

1. 安裝anaconda

下載官方anaconda python安裝包(minicondo也行)，將conda加入~/.bashrc的系統變量中(在安裝中會提示你運行 conda init，點yes就會直接複製到~/.bashrc中了)。這一步的目的是去安裝curl, curl是下載安裝brew必備的工具，此時curl會安裝在/home/username/anaconda3/bin中

conda install curl --use-local

建議這裏裝完再裝一個vim，方便文本編輯

2. 安裝brew

使用curl命令下載安裝brew，中間有一些錯誤不用管他，結束後輸入brew有返回就說明安裝成功

sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"

以後將一下brew加入~/.bashrc中

export HOMEBREW_PREFIX="/home/username/.linuxbrew";
export HOMEBREW_CELLAR="/home/username/.linuxbrew/Cellar";
export HOMEBREW_REPOSITORY="/home/username/.linuxbrew/Homebrew";
export PATH="/home/username/.linuxbrew/bin:/home/username/.linuxbrew/sbin:$PATH";
export MANPATH="/home/username/.linuxbrew/share/man:$MANPATH";
export INFOPATH="/home/username/.linuxbrew/share/info:$INFOPATH";

此時保證brew已是一個能夠在終端被調用, 接下來是關鍵的一步

在/home/username/.linuxbrew/Homebrew/Library/Homebrew/brew.sh#L200上進行加上一行

if [[ -n "$HOMEBREW_FORCE_BREWED_CURL" &&
      -x "$HOMEBREW_PREFIX/opt/curl/bin/curl" ]] &&
         "$HOMEBREW_PREFIX/opt/curl/bin/curl" --version >/dev/null
then
  HOMEBREW_CURL="$HOMEBREW_PREFIX/opt/curl/bin/curl"
elif [[ -n "$HOMEBREW_DEVELOPER" && -x "$HOMEBREW_CURL_PATH" ]]
then
  HOMEBREW_CURL="$HOMEBREW_CURL_PATH"
else
  HOMEBREW_CURL="curl"
fi
HOMEBREW_CURL="/home/username/anaconda/bin/curl" # 加上這一行！

而後輸入 brew install curl

裝完以後brew.sh會自動抹去本身以前的修改 : )，而後brew就正式能用了

好比 brew install tmux, brew install htop，只有brew有的包均可以裝(參考包列表https://formulae.brew.sh/formula/)

3. 手動編譯安裝軟件包

若是brew裏面沒有某個包，須要本身編譯的話，通常的linux軟件包都是make編譯的，通常修改下configure而後再make && make install 就行了，以下三行命令：

./configure --prefix=/home/username/.local
make
make install
# 若是要卸載 運行 make uninstall

最後分享下個人~/.bashrc ，其中 ~/.local/bin 和 ~/.local/lib加到PATH裏面是爲了本身編譯安裝用的。

export PATH=~/.local/bin:$PATH
export C_INCLUDE_PATH=$C_INCLUDE_PATH:~/.local/include
export CPLUS_INCLUDE_PATH=$CPLUS_INCLUDE_PATH:~/.local/include
export LD_LIBRARY_PATH=~/.local/lib:$LD_LIBRARY_PATH


# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/home/username/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/home/username/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/home/username/anaconda3/etc/profile.d/conda.sh"
    else
        export PATH="/home/username/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda initialize <<<

export HOMEBREW_PREFIX="/home/username/.linuxbrew";
export HOMEBREW_CELLAR="/home/username/.linuxbrew/Cellar";
export HOMEBREW_REPOSITORY="/home/username/.linuxbrew/Homebrew";
export PATH="/home/username/.linuxbrew/bin:/home/username/.linuxbrew/sbin:$PATH";
export MANPATH="/home/username/.linuxbrew/share/man:$MANPATH";
export INFOPATH="/home/username/.linuxbrew/share/info:$INFOPATH";
