1、自建yum仓库，分别为网络源和本地源
本地源：
1). 挂载iso文件
]# mkdir /mnt/cd ]# mount -o loop /dev/cdrom /mnt/cd/
2). 编辑repo文件
[local] name=Local Cd baseurl=file:///mnt/cd enabled=1 gpgcheck=0
3). 测试
]# yum clean all yum Loaded plugins: fastestmirror Cleaning repos: local Cleaning up list of fastest mirrors Other repos take up 172 M of disk space (use --verbose for details) ]# yum repolist Loaded plugins: fastestmirror Determining fastest mirrors local | 3.6 kB 00:00:00 (1/2): local/group_gz | 153 kB 00:00:00 (2/2): local/primary_db | 3.3 MB 00:00:00 repo id repo name status local Local Cd 4,071 repolist: 4,071
网络源（一）：
1). 安装http服务
yum -y install httpd
2). 挂载iso文件
]# mkdir /var/www/html/centos7/ ]# mv /root/CentOS-7-x86_64-DVD-2003.iso /var/www/html/ ]# mount -o loop /var/www/html/CentOS-7-x86_64-DVD-2003.iso /var/www/html/centos7/
3). 编辑repo文件
[centos7] name=Centos7 baseurl=http://192.168.74.103/centos7/ enable=1 gpgcheck=0
4). 测试
]# yum repolist Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile centos7 | 3.6 kB 00:00:00 (1/2): centos7/group_gz | 153 kB 00:00:00 (2/2): centos7/primary_db | 3.3 MB 00:00:00 repo id repo name status centos7 Centos7 4,071 local Local Cd 4,071 repolist: 8,142
网络源（二）：
可以搭建Nexus服务器，通过代理的方式获取最新的rpm包，可以配置yum源、apt源、pipy源等。
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). 下载编译包
]# curl -o httpd-2.4.43.tar.gz https://mirrors.tuna.tsinghua.edu.cn/apache//httpd/httpd-2.4.43.tar.gz % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 9129k 100 9129k 0 0 7758k 0 0:00:01 0:00:01 --:--:-- 7762k
2). 解压
]# tar zxf httpd-2.4.43.tar.gz
3). 环境准备
]# yum -y install apr-devel apr-util-devel gcc pcre-devel openssl-devel
4). configure脚本
]# ./configure --prefix=/usr/local/httpd-2.4.43 --enable-ssl --enable-mpms-shared
5). make && make install
6). 安装后配置
]# cd /usr/local ]# ln -s httpd-2.4.43/ httpd ]# cat /etc/profile.d/httpd.sh export PATH=/usr/local/httpd/bin:$PATH
7). 测试
]# curl http://192.168.74.103 <html><body><h1>It works!</h1></body></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
1). 创建块设备
]# 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. Device does not contain a recognized partition table Building a new DOS disklabel with disk identifier 0xe29fb483. 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): 1 First sector (2048-10485759, default 2048): Using default value 2048 Last sector, +sectors or +size{K,M,G} (2048-10485759, default 10485759): +2G Partition 1 of type Linux and of size 2 GiB is set Command (m for help): p Disk /dev/sdb: 5368 MB, 5368709120 bytes, 10485760 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0xe29fb483 Device Boot Start End Blocks Id System /dev/sdb1 2048 4196351 2097152 83 Linux Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks.
2). 格式化：预留1%可用空间,文件系统 ext4，卷标为TEST
]# mkfs.ext4 -L TEST -m 1 /dev/sdb1 ]# blkid /dev/sdb1 /dev/sdb1: LABEL="TEST" UUID="64a9946c-3c44-445a-9993-9edc57d61ba4" TYPE="ext4"
3). 挂载：开机后自动挂载至/test目录，且默认有acl挂载选项
]# mkdir /test
编辑/etc/fstab，添加： /dev/sdb1 /test ext4 defaults,acl 0 0 ]# mount -a
4). 验证：
]# mount| grep test /dev/sdb1 on /test type ext4 (rw,relatime,data=ordered)
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
]# pvcreate /dev/sdc1 Physical volume "/dev/sdc1" successfully created. ]# pvcreate /dev/sdd1 Physical volume "/dev/sdd1" successfully created.
2). 创建VG
]# vgcreate -s 16M testvg /dev/sdc1 /dev/sdd1 Volume group "testvg" successfully created
3). 创建LV
]# lvcreate -L 5G -n testlv testvg Logical volume "testlv" created.
4). 格式化
]# mkfs.ext4 /dev/testvg/testlv
5). 挂载
]# mkdir /users ]# mount /dev/testvg/testlv /users ]# mount | grep /users /dev/mapper/testvg-testlv on /users type ext4 (rw,relatime,data=ordered)
