[CentOS] 环境变量设置的三种方法

在CentOS系统中添加环境变量的方法有几种，推荐第三种方法。这里以添加 TexLive 2017 的环境变量为例进行说明。

 

1. 修改  ~/.bash_profile  文档，在文末添加以下代码：

$ vi ~/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

# path for TexLive 2017
export TEXMF=/usr/local/texlive/texmf-local
export PATH=$PATH:$HOME/.local/bin:$HOME/bin:/usr/local/texlive/2017/bin/x86_64-linux
export MANPATH=$MANPATH:/usr/local/texlive/2017/texmf-dist/doc/man
export INFOPATH=$INFOPATH:/usr/local/texlive/2017/texmf-dist/doc/info

$ source ~/.bashrc  # 在终端运行相应的变量更新，即可得到更新后的环境变量

 

 

2. 修改  ~/.bashrc  文档，在文末添加以下内容：

$ vi ~/.bashrc 
# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
    . /etc/bashrc
fi

# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=

# User specific aliases and functions

# path for TexLive 2017
export TEXMF=/usr/local/texlive/texmf-local
export PATH=$PATH:$HOME/.local/bin:$HOME/bin:/usr/local/texlive/2017/bin/x86_64-linux
export MANPATH=$MANPATH:/usr/local/texlive/2017/texmf-dist/doc/man
export INFOPATH=$INFOPATH:/usr/local/texlive/2017/texmf-dist/doc/info

$ source ~/.bashrc  # 在终端运行相应的变量更新，即可得到更新后的环境变量

 

3. 新建一个 shell 文件，命名为 ~/TexLive2017.sh ，它的内容如下，并将它拷贝到目录  /etc/profile.d/  下。

在终端运行相应的变量更新，即可得到更新后的环境变量。

$ vi ~/TexLive2017.sh
#!/bin/bash
# setting for TexLive 2017 environment variables, edit by She
export TEXMF=/usr/local/texlive/texmf-local
export PATH=$PATH:$HOME/.local/bin:$HOME/bin:/usr/local/texlive/2017/bin/x86_64-linux
export MANPATH=$MANPATH:/usr/local/texlive/2017/texmf-dist/doc/man
export INFOPATH=$INFOPATH:/usr/local/texlive/2017/texmf-dist/doc/info

$ source /etc/profile.d/texlive2017.sh
