centos 之7zip

首先，我得说几句，我第一次进行了实验。

压缩文件夹html

rar压缩   成绩5.18M

zip压缩  成绩5.06M

7z压缩   成绩870K

第一种，源代码编译安装
官网下载地址：http://www.7-zip.org/download.html
源文件项目地址：http://sourceforge.net/projects/p7zip/，眼下最新版为9.20.1。

运行下面命令下载安装：

wget http://nchc.dl.sourceforge.net/project/p7zip/p7zip/9.20.1/p7zip_9.20.1_src_all.tar.bz2
tar -jxvf p7zip_9.20.1_src_all.tar.bz2
cd p7zip_9.20.1
make
make install

最后一步make install后出现下面信息。即为安装完成

./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/DOCS

另外一种，rpm安装
下载地址：http://pkgs.repoforge.org/p7zip/，请以最新版为准。

在 CentOS 5.x 32位下安装7ZIP

wget http://pkgs.repoforge.org/p7zip/p7zip-9.20.1-1.el5.rf.i386.rpm
rpm -ivh p7zip-9.20.1-1.el5.rf.i386.rpm

在 CentOS 5.x 64位下安装7ZIP

wget http://pkgs.repoforge.org/p7zip/p7zip-9.20.1-1.el5.rf.x86_64.rpm
rpm -ivh p7zip-9.20.1-1.el5.rf.x86_64.rpm

在 CentOS 6.x 32位下安装7ZIP

wget http://pkgs.repoforge.org/p7zip/p7zip-9.20.1-1.el6.rf.i686.rpm
rpm -ivh p7zip-9.20.1-1.el6.rf.i686.rpm

在 CentOS 6.x 64位下安装7ZIP

wget http://pkgs.repoforge.org/p7zip/p7zip-9.20.1-1.el6.rf.x86_64.rpm
rpm -ivh p7zip-9.20.1-1.el6.rf.x86_64.rpm

第三种，yum安装
通过《在Centos 5.x或6.x上安装RHEL EPEL Repo》一文，安装RHEL EPEL Repo后，就可以使用yum安装7ZIP。

命令例如以下：

yum install -y p7zip
