Question

我已经尝试过虚拟盒子和码头工具来安装centos，最新版本，没有＆＃34; mke2fs＆＃34;命令。然后我尝试使用root并输入：

yum install mke2fs*
Loaded plugins: fastestmirror, ovl
Setting up Install Process
Loading mirror speeds from cached hostfile

...... 没有包mke2fs *可用。

这是为什么？它是否在mke2fs以外的另一个包名称中？

Answer 1

您可以使用yum provides。提供 =查找哪个包提供给定值

$ yum provides mke2fs
e2fsprogs-1.42.9-9.el7.x86_64 : Utilities for managing ext2, ext3, and ext4 filesystems
Repo        : base
Matched from:
Filename    : /usr/sbin/mke2fs

所以我安装了e2fsprogs（我在docker中做过）：

FROM centos:7
RUN yum -y update && \
    yum -y install e2fsprogs

构建它并启动我的容器：

$ docker run -it my-centos bash
[root@1ef2a7d930cf /]# mke2fs
Usage: mke2fs [-c|-l filename] [-b block-size] [-C cluster-size]
    [-i bytes-per-inode] [-I inode-size] [-J journal-options]
    [-G flex-group-size] [-N number-of-inodes]
    [-m reserved-blocks-percentage] [-o creator-os]
    [-g blocks-per-group] [-L volume-label] [-M last-mounted-directory]
    [-O feature[,...]] [-r fs-revision] [-E extended-option[,...]]
    [-t fs-type] [-T usage-type ] [-U UUID] [-jnqvDFKSV] device [blocks-count]

如何在centos上安装mke2fs？
