1、自建yum仓库，分别为网络源和本地源
在centos7安装yum源：
（1）本地自建yum仓库：首先需要启动神奇目录ls /misc/cd，用来挂载光盘，
1、 安装autofs软件，并启动。
2、 [root@centos7-2 ~]# yum install autofs 安装autofs
3、 [root@centos7-2 ~]# systemctl start autofs 启动autofs
4、 [root@centos7-2 ~]# systemctl enable autofs 下次开机启动autofs
5、 [root@centos7-2 yum.repos.d]# rm -rf repo.* 删除yum源多余的文件
[root@centos7-2 yum.repos.d]#vim development.repo 创建Yum仓库
[development] baseurl=file:///misc/cd #gpgcheck=0 gpgcheck=file:///misc/cd/RPM-GPG-KEY-CenstOS-7 enable=1
6、yum repolist 加载当前的yum源仓库
（2）光盘挂载到httpd服务上的yum源仓库
1、[root@centos7-2 yum.repos.d]#mkdir -pv /var/www/html/centos/6/os/x86_64/ 新建一个类似光盘的路径目录
2、[root@centos7-2 yum.repos.d]#yum install httpd -y 安装httpd服务
3、[root@centos7-2 yum.repos.d]#systemctl start httpd 启动httpd服务
4、[root@centos7-2 yum.repos.d]#mount /dev/sr0 /var/www/html/centos/6/os/x86_64 将本地光盘挂载到httpd网上
[root@centos7-2 yum.repos.d]#vim base.repo 开始创建yum仓库 [base] baseurl=http://192.168.34.101/CentOS/$releasever/os/$basearch gpgcheck= 0 enable=1
5、 yum repolist 加载当前的Yum源仓库
（3） 创建网络yum源仓库（ELPL源）：
1、[root@centos7-2 yum.repos.d]#cd /etc/yum.repos.d/
直接在阿里官网找到elpl源仓库，将repodata上级所有目录都复制出来，放到baseurl指定的目录即可：
[root@centos7-2 yum.repos.d]#vim elpl.repo [elpl] baseurl= https://mirrors.aliyun.com/epel/$releasever/x86_64 gpgcheck=0 enable=1
2、yum repolist 加载当前的yum源仓库
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。
在官网上下载httpd源码包http://httpd.apache.org，也可以在linux中输入rpm -qi httpd查看到当前下载源码httpd的网址
下载到linux的data目录下，然后进行解压：
|
1
2
3
|
[root@ansibledata]#rz[root@ansibledata]#tar xf httpd-2.4.39 |
注意：一定要在解压后的httpd目录下安装，下面的编译需要用到httdp目录下的脚本，所以我用cd httpd把目录切换到httpd中去进入cd httpd-2.4.27/
查询 cat INSTALL，里边有简单的安装过程，和一些例子
查询 cat README，（what is it ?）里边有一些Apache 的功能介绍
（1）./configure --help 查询这个脚本的用法，
--prefix=PREFIX 指定默认安装总目录, 默认为/usr/local/
--sysconfdir=/PATH 配置文件安装位置，默认就安装到指定安装总目录的下面
Optional Features: 需要什么功能
--disable-FEATURE 关闭某些功能
--enable-FEATURE 开启某些功能
下面我们就来执行这个脚本，添加一些简单的设置
手工创建账号：
|
1
|
[root@ansiblehttpd-2.4.39]#useradd -r -u 80 -d /var/www -s /sbin/nologin httpd |
（1）首先安装development-tools包，因为没有C编译工具，缺少gcc，这时候，我们需要下一个包组development tools
yum -y groupinstall "Development Tools"
|
1
|
[root@ansiblehttpd-2.4.39]#yum groupinstall "development tools" |
（2）首次安装包，会有一些提示错误，第一次安装没有一些准备好的包，可以根据提示错误进行安装：
|
1
|
[root@ansiblehttpd-2.4.39]#./configure --prefix=/app/httpd --sysconfdir=/etc/httpd24 --enable-ssl --disable-status |
（3）我们只需按照提示的错误，把需要的都安装上去（直到没有提示错误）
先查询缺少的 yum search apr-devel（一般关于开发的都叫 devel）
再安装 yum -y install apr-devel
|
1
|
[root@ansiblehttpd-2.4.39]#yum install apr-devel |
（4）此时缺少apr-util包，按照提示错误来进行下一步安装：
|
1
|
[root@ansiblehttpd-2.4.39]#yum install apr-util-devel |
|
1
|
[root@ansiblehttpd-2.4.39]#./configure --prefix=/app/httpd --sysconfdir=/etc/httpd24 --enable-ssl --disable-status |
（5）根据提示错误继续往下安装，此时缺少pcre包，安装pcre-devel包
|
1
|
[root@ansiblehttpd-2.4.39]#yum install pcre-devel |
继续执行指定路径的包安装
|
1
|
[root@ansiblehttpd-2.4.39]#./configure --prefix=/app/httpd --sysconfdir=/etc/httpd24 --enable-ssl --disable-status |
（6）根据提示的错误，安装openssl-devel包：
|
1
|
[root@ansiblehttpd-2.4.39]#yum install openssl-devel |
（7）再执行指定路径的包安装，此时就已经完成指定路径包的安装。
|
1
|
[root@ansiblehttpd-2.4.39]#./configure --prefix=/app/httpd --sysconfdir=/etc/httpd24 --enable-ssl --disable-status |
（8）configure脚本完全执行成功（多了一个Makefile）没有Makefile
（1）进行make编译，make 编译后，多了很多.o .lo 文件 （二进制文件）,在此之前的工作，任何用户都能做，并且都在httpd-2.4.27 这个目录下进行
|
1
|
[root@ansiblehttpd-2.4.39]#make |
（2）make install 安装到指定位置，只有root 能做，此时httpd的编译完成。
|
1
|
[root@ansiblehttpd]#make install |
（3）切换到/app/httpd/bin执行程序目录下，此时去执行服务启动，都必须是./apachectl start，不太方便，我们可以指定变量路径
|
1
2
3
4
5
|
[root@ansiblehttpd]#cd /app/httpd/bin[root@ansiblebin]#pwd/app/httpd/bin[root@ansiblebin]#echo ‘PATH=/app/httpd/bin:$PATH‘ > /etc/profile.d/httpd.sh 定义一个/app/httpd/bin的配置文件路径[root@ansiblebin]#apachectl start 启动当前编译的httpd服务 |
此时在网上输入本机的IP地址就可以访问信息：
导入帮助手册man
vim /etc/man_db.conf
加入一行 MANDATORY_MANPATH /app/httpd/man
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）先在/dev/sdb磁盘上创建一个2G的分区
[root@centos6~]#fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0xef64b475.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won‘t be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It‘s strongly recommended to
switch off the mode (command ‘c‘) and change display units to
sectors (command ‘u‘).
Command (m for help): m

q quit without saving changes

w write table to disk and exit

查看此时的/dev/sdb的分区大小是2G
[root@centos6~]#lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sr0 11:0 1 3.7G 0 rom sda 8:0 0 200G 0 disk ├─sda1 8:1 0 1G 0 part /boot ├─sda2 8:2 0 97.7G 0 part / ├─sda3 8:3 0 48.8G 0 part /data ├─sda4 8:4 0 1K 0 part └─sda5 8:5 0 2G 0 part [SWAP] sdb 8:16 0 200G 0 disk └─sdb1 8:17 0 15.7M 0 part
（2）指定磁盘空间及系统标记：块大小为2048byte，预留1%可用空间,文件系统 ext4，卷标为TEST
[root@centos6~]#mkfs.ext4 -b 2048 -L "TEST" -m 1 /dev/sdb1 mke2fs 1.41.12 (17-May-2010) Filesystem label=TEST OS type: Linux Block size=2048 (log=1) Fragment size=2048 (log=1) Stride=0 blocks, Stripe width=0 blocks 131560 inodes, 1052240 blocks 10522 blocks (1.00%) reserved for the super user First data block=0 Maximum filesystem blocks=538968064 65 block groups 16384 blocks per group, 16384 fragments per group 2024 inodes per group Superblock backups stored on blocks: 16384, 49152, 81920, 114688, 147456, 409600, 442368, 802816 Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 22 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override.
查看指定后的分区信息：
lsblk /dev/sdb1
[root@centos6~]#blkid /dev/sdb1 /dev/sdb1: LABEL="TEST" UUID="9250f7d0-977b-4c0b-bba8-7dfca23c3dcd" TYPE="ext4"
查看文件系统的ACL功能：
tune2fs -l /dev/sdb1
[root@centos6~]#tune2fs -l /dev/sdb1

（3）开机挂载/dev/sdb1磁盘：
vim /dev/fstab 将文件UUID写入到配置文件中即可：
[root@centos6~]#cat /etc/fstab # # /etc/fstab # Created by anaconda on Thu Aug 22 15:06:16 2019 # # 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 # UUID=26a9ab70-c62f-471f-bdf2-bb38c350526a / ext4 defaults 1 1 UUID=e1f6dde3-d380-4e79-80cc-b41fbf93f404 /boot ext4 defaults 1 2 UUID=7f570fd9-b234-46a1-9bc5-c8cf3942d9ca /data ext4 defaults 1 2 UUID=be5f6d9c-1887-4895-ac3f-c795f2eaafac swap swap defaults 0 0 UUID=9250f7d0-977b-4c0b-bba8-7dfca23c3dcd /mnt/sdb1 ext4 defaults 0 0
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）虚拟机上安上两个10G的虚拟硬盘，然后组合PV物理组：
[root@ansiblehttpd]#pvcreate /dev/{sdc,sdd}
Physical volume "/dev/sdc" successfully created.
Physical volume "/dev/sdd" successfully created.
（2）创建PE为16MB的VG组
[root@ansiblehttpd]#vgcreate -s 16m vg0 /dev/sd{c,d}
Volume group "vg0" successfully created
（3）将卷组创建成5G逻辑卷
[root@ansiblehttpd]#lvcreate -n testly -L 5G vg0 Logical Volume "testly" already exists in volume group "vg0"
（4）格式化当前的卷组
[root@ansiblehttpd]#mkfs.ext4 /dev/vg0/testly mke2fs 1.42.9 (28-Dec-2013) Filesystem label= OS type: Linux Block size=1024 (log=0) Fragment size=1024 (log=0) Stride=0 blocks, Stripe width=0 blocks 16384 inodes, 65536 blocks 3276 blocks (5.00%) reserved for the super user First data block=1 Maximum filesystem blocks=33685504 8 block groups 8192 blocks per group, 8192 fragments per group 2048 inodes per group Superblock backups stored on blocks: 8193, 24577, 40961, 57345 Allocating group tables: done Writing inode tables: done Creating journal (4096 blocks): done Writing superblocks and filesystem accounting information: done
查看当前的卷组信息：
[root@ansible~]#pvdisplay --- Physical volume --- PV Name /dev/sdc VG Name vg0 PV Size 10.00 GiB / not usable 16.00 MiB Allocatable yes PE Size 16.00 MiB Total PE 639 Free PE 635 Allocated PE 4 PV UUID AYecKo-37eD-N6sC-jL33-kCrb-ACAV-ez47oc --- Physical volume --- PV Name /dev/sdd VG Name vg0 PV Size 10.00 GiB / not usable 16.00 MiB Allocatable yes PE Size 16.00 MiB Total PE 639 Free PE 639 Allocated PE 0 PV UUID JMGIQr-CS6e-XpUb-1MNu-J4fW-faeW-twAMni
（5）挂载卷组
[root@ansiblehttpd]#mount /dev/vg0/testly /users
