先压缩原始文件

[root@laofuxi.com tmp]# zip -r mariadb.zip /root/src/mariadb-10.2.11-linux-x86_64.tar.gz

adding: root/src/mariadb-10.2.11-linux-x86_64.tar.gz (deflated 2%)

要看文件列表

[root@laofuxi.com tmp]# ls -l

total 439952

-rw-r--r-- 1 root root 450510649 Sep 7 15:53 mariadb.zip

分卷为100M一个文件

[root@laofuxi.com tmp]# zip -s 100M mariadb.zip --out mariadb_test

copying: root/src/mariadb-10.2.11-linux-x86_64.tar.gz

要看文件列表

[root@laofuxi.com tmp]# ls -l

-rw-r--r-- 1 root root 104857600 Sep 7 15:54 mariadb_test.z01

-rw-r--r-- 1 root root 104857600 Sep 7 15:54 mariadb_test.z02

-rw-r--r-- 1 root root 104857600 Sep 7 15:54 mariadb_test.z03

-rw-r--r-- 1 root root 450510649 Sep 7 15:53 mariadb.zip

合并所有分卷

[root@laofuxi.com tmp]# cat mariadb_test.z* > all.zip

-rw-r--r-- 1 root root 450510649 Sep 7 15:53 mariadb.zip

解压合并后的zip文件

[root@laofuxi.com tmp]# unzip all.zip

Archive: all.zip

warning [all.zip]: zipfile claims to be last disk of a multi-part archive;

attempting to process anyway, assuming all parts have been concatenated

together in order. Expect "errors" and warnings...true multi-part support

doesn't exist yet (coming soon).

warning [all.zip]: 419430400 extra bytes at beginning or within zipfile

(attempting to process anyway)

file #1: bad zipfile offset (local header sig): 419430404

(attempting to re-compensate)

inflating: root/src/mariadb-10.2.11-linux-x86_64.tar.gz

要看文件列表

[root@laofuxi.com tmp]# ls -l

total 1319856

-rw-r--r-- 1 root root 450510653 Sep 7 15:54 all.zip

-rw-r--r-- 1 root root 104857600 Sep 7 15:54 mariadb_test.z01

-rw-r--r-- 1 root root 104857600 Sep 7 15:54 mariadb_test.z02

-rw-r--r-- 1 root root 104857600 Sep 7 15:54 mariadb_test.z03

-rw-r--r-- 1 root root 104857600 Sep 7 15:54 mariadb_test.z04

-rw-r--r-- 1 root root 31080253 Sep 7 15:54 mariadb_test.zip

-rw-r--r-- 1 root root 450510649 Sep 7 15:53 mariadb.zip

drwxr-xr-x 3 root root 17 Sep 7 15:55 root

查看解压后的文件的md5值

[root@laofuxi.com tmp]# md5sum root/src/mariadb-10.2.11-linux-x86_64.tar.gz

463992783249787d4d00f26e3f51306b root/src/mariadb-10.2.11-linux-x86_64.tar.gz

查看原始文件md5值

[root@laofuxi.com tmp]# md5sum /root/src/mariadb-10.2.11-linux-x86_64.tar.gz

463992783249787d4d00f26e3f51306b /root/src/mariadb-10.2.11-linux-x86_64.tar.gz

通过对比md5值，发现md5值是一样的，说明压缩及解压是正常的。
