折腾：
【记录】crifan.com的WordPress网站从Linode搬家到腾讯云香港服务器
期间，需要去腾讯云香港CVM服务器中CentOS 7中去解压7z文件：
<pre class="prettyprint lang-bsh">[root@VM_0_11_centos wwwroot]# ls -lh total 8.5G drwxr-xr-x 3 www www 4.0K Dec 25 21:17 default drwxr-xr-x 2 www www 4.0K Dec 25 21:41 www.crifan.com -rw-r--r-- 1 root root 8.5G Dec 26 22:20 www.crifan.com_allFiles_20181225.7z
centos 7z uncompress
tar – Extract 7z files with standard linux tools? – Super User
7zip File: How to Uncompress 7z files on Ubuntu, Debian, Fedora
用e参数
[root@VM_0_11_centos wwwroot]# 7za e www.crifan.com_allFiles_20181225.7z -bash: 7za: command not found
7zip – How can I uncompress a *.7z file? – Ask Ubuntu
用7z x
结果才想起来，还没安装7z呢。。。
参考之前自己的：
去安装
https://sourceforge.net/projects/p7zip/files/p7zip/16.02/p7zip_16.02_src_all.tar.bz2/download
-》
https://nchc.dl.sourceforge.net/project/p7zip/p7zip/16.02/p7zip_16.02_src_all.tar.bz2
去服务器中下载
[root@VM_0_11_centos tool]# tar xvf p7zip_16.02_src_all.tar.bz2 [root@VM_0_11_centos tool]# ll -lh total 4.1M drwx--S--- 11 www ftp 4.0K Jul 14 2016 p7zip_16.02 -rw-r--r-- 1 root root 4.1M Jul 14 2016 p7zip_16.02_src_all.tar.bz2 cd p7zip_16.02 make && make install ...ake[1]: Leaving directory `/data/wwwroot/tool/p7zip_16.02/CPP/7zip/Bundles/Alone' ./install.sh /usr/local/bin /usr/local/lib/p7zip /usr/local/man /usr/local/share/doc/p7zip - installing /usr/local/bin/7za - installing /usr/local/man/man1/7z.1 - installing /usr/local/man/man1/7za.1 - installing /usr/local/man/man1/7zr.1 - installing /usr/local/share/doc/p7zip/README - installing /usr/local/share/doc/p7zip/ChangeLog - installing HTML help in /usr/local/share/doc/p7zip/DOC

去解压：
【总结】
此处去CentOS要解压7z，需要先去安装：
先用浏览器打开：
https://sourceforge.net/projects/p7zip/files/p7zip/16.02/p7zip_16.02_src_all.tar.bz2/download
会自动下载，得到下载地址，然后去服务器中用wget下载：
wget https://nchc.dl.sourceforge.net/project/p7zip/p7zip/16.02/p7zip_16.02_src_all.tar.bz2
解压：
tar xvf p7zip_16.02_src_all.tar.bz2
安装
cd p7zip_16.02 make && make install
确认已安装：
which 7za 7za --help
然后再去解压7z
7za x www.crifan.com_allFiles_20181225.7z
【后记】
How to Extract 7zip files in CentOS 7 | Unzip 7z CentOS
sudo yum install epel-release sudo yum install p7zip 7za x file.7z
有空去试试。

折腾：
【未解决】恢复crifan.com的WordPress到Vultr的CentOS7的OneinStack中
期间，去CentOS7中，突然想到，可以不用从源码中安装，去搜索7z相关的工具：
[root@crifan book.crifan.com]# yum search 7z Loaded plugins: fastestmirror Repodata is over 2 weeks old. Install yum-cron?

可以看到是有：

和之前的7z是一样的用法，核心参数是：

7za x book.crifan.com_allFiles_20190510.7z
即可。
