第六周作业

1、自建yum仓库，分别为网络源和本地源。
本地源

#通过misc便捷挂载光盘,CentOS6.8以下的版本默认开启了autofs服务,可使用misc
[root@localhost data]# rpm -qa|grep autofs    #检测是否安装了autofs
autofs-5.0.7-99.el7.x86_64                   #已安装
libsss_autofs-1.16.2-13.el7.x86_64
[root@localhost data]# systemctl start  autofs  # 开启autofs,退出系统失效
[root@localhost data]# systemctl enable autofs   # 永久开启autofs
[root@localhost data]# cd /misc/
[root@localhost misc]# ll
total 0
[root@localhost misc]# cd cd        # 光盘挂载成功
[root@localhost yum.repos.d]# df /dev/sr0      #确认光盘已经挂载到/misc/cd目录下
Filesystem     1K-blocks    Used Available Use% Mounted on
/dev/sr0         4480476 4480476         0 100% /misc/cd     
[root@localhost cd]# ll
total 686

[root@localhost cd]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ls    #将默认的yum仓库的配置文件做备份
CentOS-Base.repo  CentOS-Debuginfo.repo  CentOS-Media.repo    CentOS-Vault.repo
CentOS-CR.repo    CentOS-fasttrack.repo  CentOS-Sources.repo
[root@localhost yum.repos.d]# mkdir backup
[root@localhost yum.repos.d]# mv *.repo backup/
[root@localhost yum.repos.d]# vim base.repo    #配置仓库文件
[base]          #仓库ID，如果有多个仓库，要确保其唯一性
name=CentOS     #仓库说明，描述仓库的信息
baseurl=file:///misc/cd    #仓库的路径
enabled=1    #1表示启用该仓库，0表示禁用
gpgcheck=1   #安装包的安全检测，0表示不检测
gpgkey=file:///misc/cd/RPM-GPG-KEY-CentOS-7   #指定gpg检测时需要的公钥文件
[root@localhost yum.repos.d]# yum repolist    #查看仓库信息，说明已经配置成功

repo id                                                           repo name                                                        status
base                                                              CentOS                                                           10,097

网络源

[root@localhost yum.repos.d]# vim epel.repo  #同本地源配置类似
[epel]
name=EPEL
baseurl=http://mirrors.aliyun.com/epel/$releasever/$basearch
gpgcheck=0
enabled=1
[root@localhost yum.repos.d]# yum repolist    #检查仓库，网络仓库配置成功

repolist: 23,598

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。

[root@localhost httpd-2.4.25]#make     
....省略部分内容
-module -avoid-version  mod_rewrite.lo 
make[4]: Leaving directory `/data/httpd-2.4.25/modules/mappers'
make[3]: Leaving directory `/data/httpd-2.4.25/modules/mappers'
make[2]: Leaving directory `/data/httpd-2.4.25/modules'
make[2]: Entering directory `/data/httpd-2.4.25/support'
make[2]: Leaving directory `/data/httpd-2.4.25/support'

make[1]: Leaving directory `/data/httpd-2.4.25'
[root@localhost httpd-2.4.25]#make install 
...省略部分内容
Installing configuration files
mkdir /data/apps/httpd/conf
mkdir /data/apps/httpd/conf/extra
mkdir /data/apps/httpd/conf/original
mkdir /data/apps/httpd/conf/original/extra
...省略部分内容
make[1]: Leaving directory `/data/httpd-2.4.25'
[root@localhost httpd-2.4.25]# ls /data/apps/httpd/   #查看安装后生成的相关文件
bin  build  cgi-bin  conf  error  htdocs  icons  include  logs  man  manual  modules
[root@localhost httpd-2.4.25]# echo 'PATH=/data/apps/httpd/bin:$PATH' > /etc/profile.d/httpd.sh   #配置变量，在任意目录下都可启动服务程序
[root@localhost ~]# apachectl   #启动程序
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
httpd (pid 48328) already running
[root@localhost ~]# curl 192.168.27.134
It works!
   配置成功

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

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
暂时还未跟上进度，后续会补上作业。
