Yesterday, Chiang helped a friend of the website relocation server, because the entire site's data has more than 10GB size, the friend is also ready to upload files via FTP file, according to the fact that with Aliyun bandwidth 1M calculation, it is estimated that a lot of time to pass through. So I let it pack after the compression package direct transmission, this can also save a little time, wait until spread to about half of the time to see its practical is the RAR compression method, so I know the back to use the RAR decompression mode.
So so We use a zip or tar.gz compression mode in a Linux environment, only our previous win environment used to use RAR only, but it does not matter in Linux we can also operate, but the default environment is not the need for our own to install support RAR and Unrar format compression and decompression, the old Chiang before also Have shared the WDCP panel when the RAR decompression article (here).
First, install RAR compression and decompression environment
1, yum install unrar-y
According to the custom we generally will be tempted to see if the current environment has RAR, Unrar source package, if any can be directly installed. But generally not, so we use the following compilation method.
2. Download according to the version
The code is as follows |
Copy Code |
32 digits: http://soft.itbulu.com/php/rarlinux-5.3.0.tar.gz
64 digits: http://soft.itbulu.com/php/rarlinux-x64-5.4.b2.tar.gz
|
We have to choose according to their VPS environment is 64 or 32 bits, and then downloaded to the current machine through the wget to the following compilation. For example, I am here to use the 64-bit environment.
The code is as follows |
Copy Code |
wget http://soft.itbulu.com/php/rarlinux-x64-5.4.b2.tar.gz
TAR-ZXVF rarlinux-x64-5.4.b2.tar.gz
CD rar
Make
|
After compiling, we can use to extract or compress the file.
Second, RAR compression and decompression files
1, Extract files
The code is as follows |
Copy Code |
RAR x Itbulu.com.rar
|
The red section represents the name of the file that we need to unzip to compress the package.
2, compressed files
The code is as follows |
Copy Code |
RAR a Itbulu.com.rar file
|
The
Compresses the file folder into a Itbulu.com.rar compressed package.
Summary, the above is a RAR compression and decompression files of the general application, later if you encounter other uses to supplement. However, our general purpose is to compress and decompress, such as adding notes and other operations are rarely used.
