背景

        我的Linux是CentOS 7，很干净几乎啥都没装的状态。

安装步骤

1. 安装wget

yum install -y wget

2. 进入安装目录

cd /usr/local/

3. 下载安装包

wget https://github.com/ogham/exa/releases/download/v0.9.0/exa-linux-x86_64-0.9.0.zip

4. 解压

unzip exa-linux-x86_64-0.9.0.zip

         4.1 如果提示找不到unzip，所以先安装好unzip再重复第4步

yum install -y unzip

5. 重命名一下

mv exa-linux-x86_64 /usr/local/bin/exa

 6. 执行exa

cd ../bin
exa

提示：exa: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by exa) 

7. 安装glibc-2.18

wget http://mirrors.ustc.edu.cn/gnu/libc/glibc-2.18.tar.gz
tar -zxvf glibc-2.18.tar.gz
cd glibc-2.18
mkdir build
cd build
../configure --prefix=/usr

提示：checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking for gcc... no
checking for cc... no
checking for cl.exe... no
configure: error: in /usr/local/bin/glibc-2.18/build': configure: error: no acceptable C compiler found in $PATH See config.log' for more details

8. 不着急，提示说缺少gcc，咱就去装个gcc先

yum install -y gcc

9. 编译安装（需要耐心等待一段时间 ）

../configure --prefix=/usr
make -j4
sudo make install

10. 试试运行exa 

cd /usr/local/bin
exa -T
