Q1、自建yum仓库，分别为网络源和本地源
[root@Centos7 ~]# cd /etc/yum.repos.d/
[root@Centos7 ~]# mkdir bak
[root@Centos7 ~]# mv *.repo bak/
[root@Centos7 yum.repos.d]# vim base.repo
[cdrom]
name=cdrom base
baseurl=file:///misc/cd
gpgkey=file:///misc/cd/RPM-GPG-KEY-CentOS-$releasever
[aliyun]
name=aliyun base
baseurl=http://mirrors.aliyun.com/centos/$releasever/os/$basearch/
gpgkey=http://mirrors.aliyun.com/centos/$releasever/os/$basearch/RPM-GPG-KEY-CentOS-$releasever
gpgcheck=1
enabled=1
[EPEL]
name=EPEL base
baseurl=http://mirrors.aliyun.com/epel/$releasever/$basearch/
gpgcheck=0
enabled=1
[root@Centos7 yum.repos.d]# yum clean all
Loaded plugins: fastestmirror, langpacks
Cleaning repos: EPEL aliyun cdrom
Cleaning up list of fastest mirrors
Other repos take up 764 M of disk space (use --verbose for details)
[root@Centos7 yum.repos.d]# yum repolist

Q2、编译安装http2.4，实现可以正常访问，并将编译步骤和结果提交。
[root@Centos7 ~]# yum install gcc openssl-devel pcre-devel apr-devel apr-util-devel -y
[root@Centos7 ~]# tar xf httpd-2.4.39.tar.bz2
[root@Centos7 ~]# mkdir /apps
[root@Centos7 ~]# cd httpd-2.4.39/
[root@Centos7 httpd-2.4.39]# ./configure --prefix=/apps/http24 --sysconfdir=/etc/httpd --enable-ssl --enable-so
[root@Centos7 httpd-2.4.39]# make && make install
[root@Centos7 httpd-2.4.39]# /apps/http24/bin/apachectl start
[root@Centos7 httpd-2.4.39]# curl 192.168.139.110
<html><body><h1>It works!</h1></body></html>
Q3、创建一个2G的文件系统，块大小为2048byte，预留1%可用空间,文件系统 ext4，卷标为TEST，要求此分区开机后自动挂载至/test目录，且默认有acl挂载选项
[root@Centos7 ~]# echo -e 'n\n\n+2G\nw\n' | fdisk /dev/sda
Welcome to fdisk (util-linux 2.23.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Command (m for help): Command (m for help): All primary partitions are in use
Adding logical partition 6
First sector (325064704-419430399, default 325064704): Using default value 325064704
Last sector, +sectors or +size{K,M,G} (325064704-419430399, default 419430399): Partition 6 of type Linux and of size 2 GiB is set
Command (m for help): The partition table has been altered!
Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table. The new table will be used at
the next reboot or after you run partprobe(8) or kpartx(8)

[root@Centos7 ~]# partprobe

Q4、创建一个至少有两个PV组成的大小为20G的名为testvg的VG;要求PE大小 为16MB, 而后在卷组中创建大小为5G的逻辑卷testlv;挂载至/users目录
#先创建2个10G的分区
[root@Centos7 ~]# echo -e "\nn\n\n+10G\nt\n\n8e\nw\n" | fdisk /dev/sda
[root@Centos7 ~]# echo -e "\nn\n\n+10G\nt\n\n8e\nw\n" | fdisk /dev/sda
