1、自建yum仓库，分别为网络源和本地源
①光盘搭建本地yum仓库
挂载光盘（前提示虚拟机上已加载光盘镜像）
[root@centos7 ~]#mount /dev/sr0 /mnt
[root@centos7 ~]#lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 200G 0 disk
├─sda1 8:1 0 1G 0 part /boot
├─sda2 8:2 0 100G 0 part /
├─sda3 8:3 0 50G 0 part /data
└─sda4 8:4 0 4G 0 part [SWAP]
sr0 11:0 1 10G 0 rom /mnt
在此目录下建立yum源文件
[root@centos7 ~]#cd /etc/yum.repos.d/
[root@centos7 yum.repos.d]#vim base.repo
[base]
name=cdrom base
baseurl=file:///mnt
gpgcheck=0
gpgkey=file:///mnt/RPM-GPG-KEY-CentOS-7
enabled=1
②利用阿里云搭建网络源
在上述文件中追加配置，如下
[epel]
name=aliyun epel
baseurl=https://mirrors.aliyun.com/epel/$releasever/$basearch/
gpgcheck=0
enabled=1
更新yum源配置
[root@centos7 yum.repos.d]#yum clean all
Loaded plugins: fastestmirror, langpacks
Repository base is listed more than once in the configuration
Cleaning repos: base epel extras updates
Cleaning up list of fastest mirrors
至此yum源就可以被正常使用
2、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
①将下载好的文件复制到系统中
②解压包并查看
[root@centos7 data]#tar xvf httpd-2.4.25.tar.bz2
[root@centos7 data]#ls
httpd-2.4.25 httpd-2.4.25.tar.bz2
[root@centos7 data]#cd httpd-2.4.25/
[root@centos7 httpd-2.4.25]#ls
ABOUT_APACHE ap.d CHANGES docs httpd.spec libhttpd.dep Makefile.win
acinclude.m4 build CMakeLists.txt emacs-style include libhttpd.dsp modules

Apache.dsw BuildBin.dsp configure httpd.dsp InstallBin.dsp LICENSE
apache_probes.d buildconf configure.in httpd.mak LAYOUT Makefile.in
③安装
[root@centos7 httpd-2.4.25]#./configure --prefix=/apps/httpd66 --sysconfdir=/etc/httpd --enable-ssl --enable-so
checking for chosen layout... Apache
checking for working mkdir -p... yes
checking for grep that handles long lines and -e... /usr/bin/grep
checking for egrep... /usr/bin/grep -E
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
configure:
configure: Configuring Apache Portable Runtime library...
configure:
checking for APR... no
configure: error: APR not found. Please read the documentation.
但有错误，APR未被找到，yum补安装
[root@centos7 httpd-2.4.25]#yum install apr-devel
[root@centos7 httpd-2.4.25]#yum install apr-util-devel
继续运行，提示错误
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/
再继续安装pcre
[root@centos7 httpd-2.4.25]#yum install pcre-devel
再运行，提示错误
checking whether to enable mod_ssl... configure: error: mod_ssl has been requested but can not be built due to prerequisite failures
再继续安装mod_ssl
[root@centos7 httpd-2.4.25]#yum install mod_ssl
提示
configure: WARNING: OpenSSL version is too old
再将新的openssl安装
[root@centos7 httpd-2.4.25]#yum install openssl-devel
再次运行，安装成功
configure: summary of build options:
Server Version: 2.4.25
Install prefix: /apps/httpd66
C compiler: gcc -std=gnu99
CFLAGS: -pthread
LDFLAGS:
LIBS:
CPPFLAGS: -DLINUX -D_REENTRANT -D_GNU_SOURCE
C preprocessor: gcc -E
④make
[root@centos7 httpd-2.4.25]#make
⑤make install
[root@centos7 httpd-2.4.25]#make install
⑥添加路径至配置文件
[root@centos7 httpd-2.4.25]#cd /apps/httpd66/
[root@centos7 httpd66]#ls
bin build cgi-bin error htdocs icons include logs man manual modules
[root@centos7 httpd66]#vim /etc/profile.d/env.sh
PATH="/apps/httpd66/bin:$PATH" #添加此行
⑦生效此配置文件并查看变量
[root@centos7 httpd66]#. /etc/profile.d/env.sh
[root@centos7 httpd66]#echo $PATH
/apps/httpd66/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
⑧执行程序
[root@centos7 ~]#apachectl start
⑨查看执行效果

3、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
以我的sdb硬盘为例说明
①创建2G大小的磁盘分区
[root@centos7 ~]#fdisk /dev/sdb
Command (m for help): n
Partition type:
p primary (0 primary, 0 extended, 4 free)
e extended
Select (default p): p
Partition number (1-4, default 1):
First sector (2048-41943039, default 2048):
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-41943039, default 41943039): +2G
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
②创建好后查看
[root@centos7 ~]#lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 200G 0 disk
├─sda1 8:1 0 1G 0 part /boot
├─sda2 8:2 0 100G 0 part /
├─sda3 8:3 0 50G 0 part /data
└─sda4 8:4 0 4G 0 part [SWAP]
sdb 8:16 0 20G 0 disk
└─sdb1 8:17 0 2G 0 part
sr0 11:0 1 10G 0 rom
③创建文件系统
[root@centos7 ~]#mke2fs -t ext4 -b 2048 -L TEST -m 1 /dev/sdb1
mke2fs 1.42.9 (28-Dec-2013)
Filesystem label=TEST
OS type: Linux

④创建挂载目录并挂载
[root@centos7 ~]#mkdir /test
[root@centos7 ~]#vim /etc/fstab
.....
UUID=d96e21bf-6785-463c-9a96-1ccb84593004 /test ext4 acl 0 0 #UUID通过blkid命令查看得知
⑤重启动验证
[root@centos7 ~]#lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 200G 0 disk
├─sda1 8:1 0 1G 0 part /boot
├─sda2 8:2 0 100G 0 part /
.......
sdb 8:16 0 20G 0 disk
└─sdb1 8:17 0 2G 0 part /test
显示挂载已成功
4、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
①创建pv并显示信息
[root@centos7 ~]#pvcreate /dev/sdb1 /dev/sdb2
WARNING: ext4 signature detected on /dev/sdb1 at offset 1080. Wipe it? [y/n]: y

②创建vg卷组并显示信息
[root@centos7 ~]#vgcreate -s 16M testvg /dev/sdb1 /dev/sdb2

③创建逻辑卷并显示信息
[root@centos7 ~]#lvcreate -n testlv -L 5G testvg
Logical volume "testlv" created.
[root@centos7 ~]#lvdisplay
