第六周作业
1、自建yum仓库，分别为网络源和本地源
本地源
安装并启动autofs软件
[root@test ~]# yum -y install autofs
[root@test ~]# systemctl start autofs
[root@test ~]# systemctl enable autofs
查看光盘目录
[root@test ~]# cd /misc/cd
[root@test cd]# ll

-r--r--r-- 1 root root 2883 9月 10 03:08 TRANS.TBL
配置本地yum源文件
先移走原有的yum源文件
[root@test yum.repos.d]# cd /etc/yum.repos.d/
[root@test yum.repos.d]# mkdir -p /data/yum
[root@test yum.repos.d]# mv * /data/yum/
编辑本地yum源文件
[root@test yum.repos.d]# vim CentOS-Base.repo
file=/misc/cd
[base]
name=CentOS-Base
baseurl=file:///misc/cd
gpgcheck=0
清空原有缓存
[root@test yum.repos.d]# yum clean all
生成新yum源缓存
[root@test yum.repos.d]# yum makecache
已加载插件：fastestmirror
Loading mirror speeds from cached hostfile
base | 3.6 kB 00:00:00
(1/2): base/other_db | 2.6 MB 00:00:00
(2/2): base/filelists_db | 7.3 MB 00:00:00
元数据缓存已建立
网络源
安装httpd服务
[root@test ~]# yum -y install httpd
[root@test html]# service httpd start
复制rmp包和元数据库到html目录
[root@test html]# cp -rp /misc/cd/{Packages,repodata} /var/www/html/
编辑yum源文件
[root@test html]# vim /etc/yum.repos.d/CentOS-Base.repo
[base]
name=CentOS-Base
#baseurl=file:///misc/cd
baseurl=http://172.16.1.21/
gpgcheck=0
清空已有缓存，生成新缓存
[root@test html]# yum clean all
已加载插件：fastestmirror
正在清理软件源： base
Cleaning up list of fastest mirrors
Other repos take up 55 M of disk space (use --verbose for details)
[root@test html]# yum makecache
已加载插件：fastestmirror

(3/4): base/filelists_db | 7.3 MB 00:00:00
(4/4): base/other_db | 2.6 MB 00:00:00
元数据缓存已建立
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。
下载httpd源码包
[root@test tools]# ll
总用量 6868
-rw-r--r-- 1 root root 7030539 9月 30 12:05 httpd-2.4.39.tar.bz2
解压软件包
解压时报错
[root@test tools]# tar xvf httpd-2.4.39.tar.bz2
tar (child): cannot run bzip2: 没有那个文件或目录
tar (child): trying lbzip2
tar (child): lbzip2：无法 exec: 没有那个文件或目录
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now
解决方法
这是因为系统中缺少bzip2软件导致的。
[root@test tools]# yum -y install bzip2
[root@test tools]# tar xvf httpd-2.4.39.tar.bz2
[root@test tools]# ll
总用量 6872
drwxr-sr-x 11 root 40 4096 3月 27 2019 httpd-2.4.39
-rw-r--r-- 1 root root 7030539 9月 30 12:05 httpd-2.4.39.tar.bz2
编译安装httpd服务
目录中主要文件
[root@test httpd-2.4.39]# ll
总用量 2156
-rwxr-xr-x 1 root 40 1199771 3月 27 2019 configure #编译工具
-rw-r--r-- 1 root 40 3782 5月 18 2016 INSTALL #说明文件
安装开发包组
[root@test ~]# yum groupinstall "Development Tools" -y
创建运行httpd服务的用户
[root@test ~]# groupadd www
[root@test ~]# useradd -g www www -s /sbin/nologin
编译httpd服务
[root@test httpd-2.4.39]# ./configure --prefix=/app/

缺什么包就安装什么包。
安装依赖包并编译
[root@test httpd-2.4.39]# yum -y install apr-util-devel apr-devel pcre-devel
[root@test httpd-2.4.39]# ./configure --prefix=/app/
[root@test httpd-2.4.39]# echo $?
0
[root@test httpd-2.4.39]# make && make install
编辑httpd配置文件
[root@test app]# vim conf/httpd.conf
51 Listen 172.16.1.21:80
165 User www
166 Group www
196 ServerName 172.16.1.21:80
启动httpd服务
[root@test ~]# /app/bin/httpd
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
[root@test ~]# fdisk -l /dev/sdb
Disk /dev/sdb: 214.7 GB, 214748364800 bytes, 419430400 sectors

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
[root@test ~]# fdisk -l /dev/sdb
