在SHH或者終端下輸入:yum –y install p7zip（如果提示找不到資源,則要自己下載編譯安裝,命令如:）

wget http://nchc.dl.sourceforge.net/sourceforge/p7zip/p7zip_4.65_src_all.tar.bz2
tar -xjvf p7zip_4.65_src_all.tar.bz2
cd p7zip_4.65
make && make install

看到如下資訊就說明你安裝成功了:

./install.sh /usr/local/bin /usr/local/lib/p7zip /usr/local/man /usr/local/share/doc/p7zip

- installing /usr/local/bin/7

- installing /usr/local/man/man1/7z.1

- installing /usr/local/man/man1/7za.1

- installing /usr/local/share/doc/p7zip/README

- installing /usr/local/share/doc/p7zip/ChangeLog

- installing HTML help in /usr/local/share/doc/p7zip/DOCS
