第六周作业
1、自建yum仓库，分别为网络源和本地源
配置本地光盘作为yum源仓库：
#原仓库文件做备份
[root@centos7 17:40:00 ~]#cd /etc/yum.repos.d/
[root@centos7 17:40:08 yum.repos.d]#ls
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo
CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo
[root@centos7 17:40:10 yum.repos.d]#mkdir backup
[root@centos7 17:40:24 yum.repos.d]#mv *.repo backup/
[root@centos7 17:40:40 yum.repos.d]#ls
backup
#确认光盘已经挂载在/misc/cd目录下
[root@centos7 17:40:44 yum.repos.d]#df /dev/sr0
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sr0 4480476 4480476 0 100% /misc/cd
#新建本地磁盘yum源，编辑yum源文件
[root@centos7 17:43:36 yum.repos.d]#cat >> base.repo <<EOF
> [base]
> name=CentOS7
> baseurl=file:///misc/cd
> enabled=1
> gpgcheck=0 -------- 指定了不检查
> EOF
[root@centos7 17:46:43 yum.repos.d]#
#用yum repolist查看设置的仓库信息
[root@centos7 17:48:30 yum.repos.d]#yum repolist
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
repo id repo name status
!base CentOS7 10,070
repolist: 10,070
#能看到仓库文件中多出base.repo
[root@centos7 17:48:34 yum.repos.d]#ls
backup base.repo
#找到阿里云epel网络仓库链接
http://mirrors.aliyun.com/epel/7/x86_64/
[root@centos7 17:56:26 yum.repos.d]#vim epel.repo
[epel]

baseurl=http://mirrors.aliyun.com/epel/$releasever/$basearch/ -------- 路径用变量替换

gpgcheck=0

Not using downloaded base/repomd.xml because it is older than what we have:

#能看到仓库文件中多出epel.repo
[root@centos7 18:03:56 yum.repos.d]#ls
backup base.repo epel.repo
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
#从阿里云下载包
[root@centos7 12:40:14 data]#wget http://mirrors.aliyun.com/apache/httpd/httpd-2.4.46.tar.bz2
#解包
[root@centos7 12:41:57 data]#tar xvf httpd-2.4.46.tar.bz2
#进入目录下
[root@centos7 12:42:23 data]#cd httpd-2.4.46/
#指定安装路径、特性等
[root@centos7 12:43:37 httpd-2.4.46]#./configure \
> --prefix=/apps/httpd24\
> sysconfdir=/etc/httpd24\
> --enable-ssl\
> --enable-so
checking for chosen layout... Apache

configure: error: APR not found. Please read the documentation.
#根据error安装其他相关软件
[root@centos7 12:48:22 httpd-2.4.46]#yum install apr-devel -y
[root@centos7 12:48:51 httpd-2.4.46]#yum install apr-util-devel -y
[root@centos7 12:51:15 httpd-2.4.46]#yum install pcre-devel -y
[root@centos7 12:52:32 httpd-2.4.46]#yum install openssl-devel -y
[root@centos7 12:51:40 httpd-2.4.46]#./configure \--prefix=/apps/httpd24 \sysconfdir=/etc/httpd24 \--enable-ssl \--enable-so
#再次执行成功后开始make
[root@centos7 13:06:14 httpd-2.4.46]#make
[root@centos7 13:08:39 httpd-2.4.46]#make install
#可在安装路径下看到httpd24
[root@centos7 13:14:08 ~]#ls /apps/
httpd24
#为方便执行将httpd的bin路径加到$PATH中(也可不加,后用路径执行)
#打开apache服务
[root@centos7 13:14:02 ~]#apachectl start -------- 启动不会自动打开服务，需将/apps/httpd24/bin/apachectl start写入/etc/rc.d/rc.local中
#页面编辑在index.html中
[root@centos7 13:33:13 httpd24]#cd /apps/httpd24/htdocs/
[root@centos7 13:33:19 htdocs]#ls
index.html
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
mkfs.ext4 -b 2048 -m 1 -L TEST /dev/sdb1
mkdir /test
mount -t ext4 -o acl /dev/sdb1 /test
#开机后自动挂载，将配置写入/etc/fstab中
[root@centos7 14:37:05 data]#vim /etc/fstab
#
# /etc/fstab
# Created by anaconda on Mon Aug 10 23:28:58 2020
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info

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
- 用10G的/dev/sdb3和10G的/dev/sdc1组成物理卷组，先创建两个10G分区并将分区格式改为8e(LVM)
#/dev/sdc1的操作也参考如下
[root@centos7 14:44:46 data]#fdisk /dev/sdb
Welcome to fdisk (util-linux 2.23.2).
