一、自建yum仓库，分别为网络源和本地源
[root@centos7 ~]# cd /etc/yum.repos.d/ [root@centos7 yum.repos.d]# mkdir bak #建立备份文件夹 [root@centos7 yum.repos.d]# mv *.repo bak/ #将系统自带yum仓库备份 [root@centos7 yum.repos.d]# vim base.repo #新建仓库文件 [root@centos7 yum.repos.d]# cat base.repo [development] #本地光盘yum源 name=dvdbase repo baseurl=file:///mnt/cdrom/ enabled=1 gpgcheck=1 gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-CentOS-7 [aliyun] #阿里云yum源 name=aliyun repo baseurl=https://mirrors.aliyun.com/centos/$releasever/os/$basearch/ enabled=1 gpgchedk=1 gpgkey=https://mirrors.aliyun.com/centos/$releasever/os/$basearch/RPM-GPG-KEY-CentOS-$releasever [root@centos7 yum.repos.d]# mkdir /mnt/cdrom/ #创建光盘挂载点 [root@centos7 yum.repos.d]# mount /dev/sr0 /mnt/cdrom/ #挂载光盘 [root@centos7 yum.repos.d]# yum clean all Loaded plugins: fastestmirror, langpacks Cleaning repos: aliyun development Cleaning up list of fastest mirrors Other repos take up 86 M of disk space (use --verbose for details) [root@centos7 yum.repos.d]# yum repolist #查看生效的yum源 Loaded plugins: fastestmirror, langpacks Determining fastest mirrors aliyun | 3.6 kB 00:00:00 development | 3.6 kB 00:00:00 (1/4): development/group_gz | 166 kB 00:00:00 (2/4): development/primary_db | 6.0 MB 00:00:00 (3/4): aliyun/7/x86_64/group_gz | 165 kB 00:00:00 (4/4): aliyun/7/x86_64/primary_db | 6.0 MB 00:00:03 repo id repo name status aliyun/7/x86_64 aliyun repo 10,097 development dvdbase repo 10,019 repolist: 20,116
二、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
[root@centos7 ~]# ll httpd-2.4.39.tar #准备包 -rw-r--r-- 1 root root 41472000 Dec 3 17:57 httpd-2.4.39.tar [root@centos7 ~]# tar -xvf httpd-2.4.39.tar #解包 [root@centos7 ~]# cd httpd-2.4.39/ [root@centos7 httpd-2.4.39]# ./configure --prefix=/usr/local/httpd #编译安装 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-pc-linux-gnu checking host system type... x86_64-pc-linux-gnu checking target system type... x86_64-pc-linux-gnu configure: configure: Configuring Apache Portable Runtime library... configure: checking for APR... no configure: error: APR not found. Please read the documentation. #发现有错误，一般都是缺少相关包，经过几次提示，安装好以下包后未报错 [root@centos7 httpd-2.4.39]# yum install -y apr-devel apr-util-devel gcc pcre-devel [root@centos7 httpd-2.4.39]# ./configure --prefix=/usr/local/httpd 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-pc-linux-gnu checking host system type... x86_64-pc-linux-gnu checking target system type... x86_64-pc-linux-gnu ...中间省略 configure: summary of build options: Server Version: 2.4.39 Install prefix: /usr/local/httpd C compiler: gcc -std=gnu99 CFLAGS: -pthread CPPFLAGS: -DLINUX -D_REENTRANT -D_GNU_SOURCE LDFLAGS: LIBS: C preprocessor: gcc -E [root@centos7 httpd-2.4.39]# make [root@centos7 httpd-2.4.39]# make install [root@centos7 httpd-2.4.39]# /usr/local/httpd/bin/apachectl start #安装完成后启动服务 [root@centos7 httpd-2.4.39]# curl http://192.168.214.17 #测试访问是可以的 <html><body><h1>It works!</h1></body></html>
三、创建一个2G的文件系统，块大小为2068byte，预留1%可用空间，文件系统ext4，卷标为TEST，要求些分区开机后自动挂载至/test目录，且默认有acl挂载选项
[root@centos7 ~]# fdisk /dev/sdb #新建分区 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 0x001b493c. 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: 0x001b493c Device Boot Start End Blocks Id System 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: 0x001b493c 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. [root@centos7 ~]# lsblk /dev/sdb NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdb 8:16 0 5G 0 disk └─sdb1 8:17 0 2G 0 part #开始创建文件系统 [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 Block size=2048 (log=1) Fragment size=2048 (log=1) Stride=0 blocks, Stripe width=0 blocks 131072 inodes, 1048576 blocks 10485 blocks (1.00%) reserved for the super user First data block=0 Maximum filesystem blocks=269484032 64 block groups 16384 blocks per group, 16384 fragments per group 2048 inodes per group Superblock backups stored on blocks: 16384, 49152, 81920, 114688, 147456, 409600, 442368, 802816 Allocating group tables: done Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done [root@centos7 ~]# blkid /dev/sdb1 /dev/sdb1: LABEL="TEST" UUID="c3f133c8-6e14-425d-8b24-f90ab30bb8d1" TYPE="ext4" [root@centos7 ~]# mkdir /test #创建挂载目录 [root@centos7 ~]# mount -o acl /dev/sdb1 /test #临时挂载 [root@centos7 ~]# vim /etc/fstab #在fstab中添加以下内容，实现开机自动挂载 UUID=c3f133c8-6e14-425d-8b24-f90ab30bb8d1 /test ext4 defaults,acl 0 0
四、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、新增两块硬盘，大小分别为5G和15G，设备名分别为 /dev/sdb 和 /dev/sdc
[root@centos7 ~]# lsblk /dev/sdb /dev/sdc NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdb 8:16 0 5G 0 disk sdc 8:32 0 15G 0 disk
2、创建PV
[root@centos7 ~]# pvcreate /dev/sd{b,c} Physical volume "/dev/sdb" successfully created. Physical volume "/dev/sdc" successfully created. [root@centos7 ~]# pvs PV VG Fmt Attr PSize PFree /dev/sdb lvm2 --- 5.00g 5.00g /dev/sdc lvm2 --- 15.00g 15.00g
3、创建VG，并设置PE大小为16MB
[root@centos7 ~]# vgcreate testvg /dev/sd{b,c} -s 16m
Volume group "testvg" successfully created
[root@centos7 ~]# vgs
VG #PV #LV #SN Attr VSize VFree
testvg 2 0 0 wz--n- <19.97g <19.97g
[root@centos7 ~]# vgdisplay

VG UUID fLJ0GI-hg5u-1QJ0-7ihI-ezKF-RyIP-TQUOgh
4、创建LV
[root@centos7 ~]# lvcreate -n testlv -L 5G testvg Logical volume "testlv" created. [root@centos7 ~]# lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert testlv testvg -wi-a----- 5.00g [root@centos7 ~]# lvdisplay --- Logical volume --- LV Path /dev/testvg/testlv LV Name testlv VG Name testvg LV UUID DUZV6O-Guj4-C3IR-NEwI-Bj4d-F9Xj-W2jqal LV Write Access read/write LV Creation host, time centos7.localdomain, 2019-12-03 20:13:45 +0800 LV Status available # open 0 LV Size 5.00 GiB Current LE 320 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 8192 Block device 253:0
5、创建文件系统，并挂载
[root@centos7 ~]# mkfs.xfs /dev/testvg/testlv meta-data=/dev/testvg/testlv isize=512 agcount=4, agsize=327680 blks = sectsz=512 attr=2, projid32bit=1 = crc=1 finobt=0, sparse=0 data = bsize=4096 blocks=1310720, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 ftype=1 log =internal log bsize=4096 blocks=2560, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 [root@centos7 ~]# blkid /dev/sda1: UUID="06fb735b-a954-479b-a7e2-5615d5ac1429" TYPE="xfs" /dev/sda2: UUID="39a8e496-0019-4c2e-9cfe-2bb657078465" TYPE="xfs" /dev/sda3: UUID="bf1909f2-e77e-4fe2-b8a8-c48bfb2dfeac" TYPE="xfs" /dev/sda5: UUID="18046ac9-2bc9-4b83-b179-1453c4c40c51" TYPE="swap" /dev/sdb: UUID="iJM4vP-g6pN-W0N5-J7k8-5u9w-Ywz2-Fdp1AR" TYPE="LVM2_member" /dev/sdc: UUID="ZRpN8E-SD9n-p1sN-i623-vsAO-iqSL-6WYo7D" TYPE="LVM2_member" /dev/mapper/testvg-testlv: UUID="7a0d0bc4-938c-4bbd-843c-0b248aec174b" TYPE="xfs" [root@centos7 ~]# mkdir /users #创建挂载点 [root@centos7 ~]# mount /dev/mapper/testvg-testlv /users #临时挂载 [root@centos7 ~]# cd /users/ #如要实现自动化永久挂载，可以/etc/fstab 文件后添加以下内容 [root@centos7 users]# vim /etc/fstab UUID=iJM4vP-g6pN-W0N5-J7k8-5u9w-Ywz2-Fdp1AR /users xfs defaults 0 0
