CentOS Linux 下不安装 rpm 包查看其里面的内容

实验平台：CentOS Linux release 7.6.1810

rpm 包：mysql-community-client-5.7.10-1.el7.x86_64.rpm

1.查看 rpm 里有那些文件

• rpm2cpio

$ rpm2cpio mysql-community-client-5.7.10-1.el7.x86_64.rpm |cpio -t
./usr/bin/mysql
./usr/bin/mysql_config
./usr/bin/mysql_config-64
./usr/bin/mysql_config_editor
./usr/bin/mysqladmin
./usr/bin/mysqlbinlog
./usr/bin/mysqlcheck
./usr/bin/mysqldump
./usr/bin/mysqlimport
./usr/bin/mysqlpump
./usr/bin/mysqlshow
./usr/bin/mysqlslap
./usr/share/doc/mysql-community-client-5.7.10
./usr/share/doc/mysql-community-client-5.7.10/COPYING
./usr/share/doc/mysql-community-client-5.7.10/README
./usr/share/man/man1/mysql.1.gz
./usr/share/man/man1/mysql_config_editor.1.gz
./usr/share/man/man1/mysqladmin.1.gz
./usr/share/man/man1/mysqlbinlog.1.gz
./usr/share/man/man1/mysqlcheck.1.gz
./usr/share/man/man1/mysqldump.1.gz
./usr/share/man/man1/mysqlimport.1.gz
./usr/share/man/man1/mysqlpump.1.gz
./usr/share/man/man1/mysqlshow.1.gz
./usr/share/man/man1/mysqlslap.1.gz
222783 blocks

• rpm

$ rpm -qlp mysql-community-client-5.7.10-1.el7.x86_64.rpm 
warning: mysql-community-client-5.7.10-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

/usr/share/man/man1/mysqlpump.1.gz
/usr/share/man/man1/mysqlshow.1.gz
/usr/share/man/man1/mysqlslap.1.gz

2.提取 rpm 包里的文件

$ rpm2cpio mysql-community-client-5.7.10-1.el7.x86_64.rpm | cpio -idmv
#会提取到当前目录下，可以看到会多了一个 usr/ 目录，同前面查看包里的内容一致
$ tree usr/
usr/

            ├── mysqladmin.1.gz

            ├── mysqlcheck.1.gz
            ├── mysql_config_editor.1.gz
            ├── mysqldump.1.gz
            ├── mysqlimport.1.gz
            ├── mysqlpump.1.gz
            ├── mysqlshow.1.gz
            └── mysqlslap.1.gz

6 directories, 24 files

与 -idmv 参数一致，不会输出提取文件列表，相当于静默输出

$ rpm2cpio mysql-community-client-5.7.10-1.el7.x86_64.rpm | cpio --extract --make-directories

或者使用

$ rpm2cpio mysql-community-client-5.7.10-1.el7.x86_64.rpm > mysql.cpio
$ cpio -i --make-directories < mysql.cpio

所得到的结果都是一样，都是将 rpm 包里的文件提取出来，过程略微不同
