1. Self-built yum repository, which is the network source and the local source respectively.

1) Mount the CD image

[root@centos7 ~] # mount / dev/sr0 / mnt/

[root@centos7] # df-h

/ dev/mapper/centos-root 60G 5.2G 55G 9% /

Tmpfs 200m 0 200m 0% / run/user/0

2) build local sources

[root@centos7 yum.repos.d] # cat > local.repo name=centos7.6

Baseurl= file:///mnt

> enabled=1

> gpgcheck=0

> EOF

3) install httpd and build network yum source

[root@centos7 yum.repos.d] # yum install httpd-y # successful installation means that the local source takes effect

[root@centos7 html] # cd / var/www/html

[root@centos7 html] # ln-s / mnt centos7.6

[root@centos7 html] # ls centos7.6/

CentOS_BuildTag GPL LiveOS RPM-GPG-KEY-CentOS-7

EFI images Packages RPM-GPG-KEY-CentOS-Testing-7

EULA isolinux repodata TRANS.TBL

4) verify the network yum source (on another centos7)

Configure to use a network yum source:

[root@jumpserver yum.repos.d] # cat local.repo

[local]

Name=centos7.6

Ip/centos7.6 of yum source for baseurl=http:// network

Enabled=1

Gpgcheck=0

[root@jumpserver yum.repos.d] #

Successful installation of httpd indicates that the network yum source is available

[root@jumpserver yum.repos.d] # yum install httpd-y

2, compile and install http2.4, the implementation can be accessed normally, and submit the compilation steps and results.

1) decompression

[root@centos7 bin] # rpm-qi httpd

Package httpd is not installed

[root@centos7 src] # tar-xf httpd-2.4.41.tar.gz

2) Configure

[root@centos7 src] # cd httpd-2.4.41/

[root@centos7 httpd-2.4.41] #. / configure

Install the missing dependency packages:

[root@centos7 httpd-2.4.41] # yum install apr* pcre*-y

[root@centos7 src] # cd httpd-2.4.41/

3) compilation

[root@centos7 httpd-2.4.41] # make

4) installation

[root@centos7 httpd-2.4.41] # make install

5) start and verify

[root@centos7 bin] # pwd

/ usr/local/apache2/bin

[root@centos7 bin] #. / apachectl-k start

[root@centos7 bin] # ps aux | grep apache

[root@centos7 bin] # curl localhost

It works!

[root@centos7 bin] #

3. Create a 2G file system with a block size of 2048byte and reserve 1% free space. The file system ext4 and the volume label are TEST. This partition is required to be automatically mounted to the / test directory when powered on, and there is an acl mount option by default.

1) add a hard disk to the virtual machine and let the system recognize the hard disk immediately

2) create a 2G partition

[root@centos7 ~] # fdisk / dev/sdb

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.

3) create a partition and mount it as required

[root@centos7] # mke2fs-t ext4-b 2048-L 'TEST'-M1 / dev/sdb1

[root@centos7 ~] # echo "/ dev/sdb1 / test ext4 acl 0" > > / etc/fstab

[root@centos7 ~] # mkdir / test

[root@centos7] # mount-a

4. Create a 20G VG; named testvg consisting of at least two PV requires that the PE size be 16MB, and then create a 5G logical volume testlv; in the volume group and mount it to the / users directory 1) create two 10G partitions
