CentOS（linux下）安装7-Zip（7za压缩软件）以及解压命令，只打包不压缩，加密的方法

小樱

1. wget --no-check-certificate https://downloads.sourceforge.net/project/p7zip/p7zip/16.02/p7zip_16.02_src_all.tar.bz2
   
2. tar -xjvf p7zip_16.02_src_all.tar.bz2
   
3. cd p7zip_16.02
   
4. make -j 4
   
5. make install
   

复制代码

看到如下信息就说明你安装成功了:

1. ./install.sh /usr/local/bin /usr/local/lib/p7zip /usr/local/man /usr/local/share/doc/p7zip
   
2. - installing /usr/local/bin/7za
   
3. - installing /usr/local/man/man1/7z.1
   
4. - installing /usr/local/man/man1/7za.1
   
5. - installing /usr/local/man/man1/7zr.1
   
6. - installing /usr/local/share/doc/p7zip/README
   
7. - installing /usr/local/share/doc/p7zip/ChangeLog
   
8. - installing HTML help in /usr/local/share/doc/p7zip/DOC

复制代码

这时如果发现乱码,请执行命令

1. export LANG=zh_CN.GBK

复制代码

7zip命令使用方法：
7zip命令7za

具体路径/usr/local/bin/7za，shell脚本记得写全，不然计划任务无法调用提示命令未找到

7za {a|d|l|e|u|x} 压缩包文件名 {文件列表或目录，可选}
a 向压缩包里添加文件或创建压缩包，如向vpser.7z添加vpser001.jpg，执行：7za a vpser.7z vpser001.jpg；将vpser目录压缩打包执行：7za a vpser.7z vpser；
d 从压缩里删除文件，如将vpser.7z里的test.jpg删除，执行：7za d vpser.7z test.jpg
l 列出压缩包里的文件，如列出vpser.7z里的文件，执行：7za l vpser.7z
e 解压到当前目录，目录结构会被破坏，如vpser.rar内有如下目录及文件123/456/789.html，执行：7za e vpser.rar，目录123和456及文件789.html都会存放在当前目录下。
x 以完整路径解压。
-p 指定密码。
7za x archive.zip -psecret ：将设有密码“secret”的压缩档案 archive.zip 中所有文件释放。


打包111.sql文件为111.7z，并且设置密码为123456

打包方法：7za a 111.7z 111.sql -mx=0 -p123456

解包方法：7za x 111.7z -p123456

解包方法（文件已存在时直接覆盖）：7za -y x 111.7z -p123456

进行分卷，第一个分卷为10MB；第二个为15MB，剩下全部为20 MB。
7za a 111.7z 111.sql -mx=0 -p123456 -v10m -v15m -v20m
