第六周

1.自建yum仓库，分别为网络源和本地源。

1）挂载光盘
mount -r /dev/cdrom /mnt/cdrom/
cp -rv /mnt/cdrom /media/cdrom
umount /mnt/cdrom
2）配置/etc/yum.repos.d/CentOS-Base.repo文件
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
vim /etc/yum.repos.d/CentOS-Base.repo

#####################################################################

gpgcheck=0

3）清除缓存重新建立
yum clean all
yum makecache

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）下载apr-1.5.2.tar.gz，apr-util-1.5.2.tar.gz（两个apr下载1.5的高版本后面make会报错），pcre-8.43.tar.gz，httpd-2.4.41.tar.gz
wget https://archive.apache.org/dist/apr/apr-1.5.2.tar.gz
wget https://archive.apache.org/dist/apr/apr-util-1.5.2.tar.gz
wget https://sourceforge.net/projects/pcre/files/pcre/8.43/pcre-8.43.tar.gz
wget http://mirror.bit.edu.cn/apache//httpd/httpd-2.4.41.tar.gz
2）环境安装
tar -zxvf apr-1.5.2.tar.gz 
tar -zxvf apr-util-1.5.2.tar.gz
tar -zxvf pcre-8.43.tar.gz
tar -zxvf httpd-2.4.41.tar.gz
mv apr-1.5.2 /usr/local/httpd-2.4.41/srclib/apr
mv apr-util-1.5.2 /usr/local/httpd-2.4.41/srclib/apr-util
yum -y install gcc gcc-c++
3）安装pcre
cd pcre-8.43
./configure --prefix=/usr/local/pcre
make
make install
4）安装http2.4
cd ../httpd-2.4.41/
./configure --prefix=/usr/local/httpd --sysconfdir=/etc/httpd2 --with-included-apr --with-pcre=/usr/local/pcre
make
make install
/usr/local/httpd/bin/apachectl start
5）关闭防火墙
firewall-cmd --permanent --add-port=80/tcp

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。

1）创建2G分区
[root@localhost /]# fdisk /dev/sdb
Command (m for help): n
Partition type:
    p   primary (0 primary, 0 extended, 4 free)
    e   extended
Select (default p):
Using default response p
Partition number (1-4, default 1): 
First sector (2048-20971519, default 2048):
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-20971519, default 20971519): +2G
Partition 1 of type Linux and of size 2 GiB is set

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.

2）创建文件系统
[root@localhost /]# mkfs.ext4 -b 2048 -m 1 -L 'TEST' /dev/sdb1
3）创建文件夹挂载
[root@localhost /]# mkdir /test
[root@localhost /]# mount /dev/sdb1 /test
4）设置开机启动
[root@localhost /]# vi /etc/fstab
####################################################################
/dev/sdb1                                 /test                   ext4    defaults,acl    0 0
####################################################################
mount -a

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
[root@localhost ~]# pvcreate /dev/sdc{1,2}
[root@localhost ~]# pvs
  PV         VG Fmt  Attr PSize  PFree
  /dev/sdc1     lvm2 ---  10.00g 10.00g
  /dev/sdc2     lvm2 ---  10.00g 10.00g
2）创建VG
[root@localhost ~]# vgcreate -s 16M testvg /dev/sdc{1,2}
  Volume group "testvg" successfully created
3）创建lv
[root@localhost ~]# lvcreate -L 5G -ntestlv testvg
  Logical volume "testlv" created.
4）格式化
[root@localhost ~]# mkfs.ext4 /dev/testvg/testlv
[root@localhost ~]# blkid /dev/testvg/testlv
/dev/testvg/testlv: UUID="3bcaed8e-6dab-43f5-bd68-6d7dc61f4c36" TYPE="ext4"
5）挂载
[root@localhost ~]# mkdir /users
[root@localhost ~]# mount /dev/testvg/testlv /users
[root@localhost ~]# df -h
Filesystem                 Size  Used Avail Use% Mounted on
/dev/mapper/testvg-testlv  4.8G   20M  4.6G   1% /users
