3.YUM源管理(40分)
假设当前有一个centos7.2-1511.iso的镜像文件，使用这个文件配置yum源，要求将这个镜像文件挂载在/opt/centos目录。还存在一个ftp源，IP地址为192.168.100.200，ftp配置文件中配置为anon_root=/opt，/opt目录中存在一个iaas目录（该目录下存在一个repodata目录）请问如何配置自己的local.repo文件，使得可以使用这两个地方的软件包，安装软件。请将local.repo文件的内容以文本形式提交到答题框。
- 这题是假设有这些东西，写对就行了，或者使用一个xserver1做vsftpd服务，将centos7.2-1511.iso上传到xserver2
xserver2:
[root@xserver2 ~]# systemctl stop firewalld
[root@xserver2 ~]# systemctl disable firewalld
# 注释：selinux防火墙，设置访问模式（得重启才生效）：
[root@xserver2 ~]# vim /etc/selinux/config
# 注释：将SELINUX=enforcing改成SELINUX=Permissive
SELINUX=Permissive
# 注释：配置临时访问模式（无需重启）：
[root@xserver2 ~]# setenforce 0
[root@xserver2 ~]# getenforce
Permissive
[root@xserver2 ~]# mount -o loop CentOS-7-x86_64-DVD-1511.iso /opt/centos/
mount: /dev/loop0 is write-protected, mounting read-only
[root@xserver2 ~]# cat /etc/yum.repos.d/local.repo

使用提供的虚拟机和软件包，完成KVM服务的安装与KVM虚拟机的启动。使用提供的cirros镜像与qemu-ifup-NAT脚本启动虚拟机，启动完毕后登录，登录有执行ip addr list命令，将该命令的返回结果以文本形式提交到答题框。
- 将kvm_yum上传到root目录，将qemu-ifup-NAT.txt重命名为qemu-ifup-NAT.sh：
[root@localhost ~]# vim /etc/yum.repos.d/local.repo
[centos]
name=centos
baseurl=file:///opt/centos

gpgcheck=0
[kvm]

[root@localhost ~]# ln -sv /usr/libexec/qemu-kvm /usr/bin/qemu-kvm
‘/usr/bin/qemu-kvm’ -> ‘/usr/libexec/qemu-kvm’
[root@localhost ~]# mv qemu-ifup-NAT.txt qemu-ifup-NAT.sh
[root@localhost ~]# chmod +x qemu-ifup-NAT.sh

使用提供的虚拟机和软件包，安装docker compose服务，安装完毕后，使用命令查看docker compose的版本信息，将查询版本信息的命令与返回结果已文本形式提交到答题框。
- 上传docker-compose-Linux-x86_64.64并重命名docker-compose：
[root@zookeeper1 ~]# mv docker-compose-Linux-x86_64.64 /usr/local/bin/
[root@zookeeper1 ~]# mv /usr/local/bin/docker-compose-Linux-x86_64.64 /usr/local/bin/docker-compose
[root@zookeeper1 ~]# chmod +x /usr/local/bin/docker-compose
[root@zookeeper1 ~]# docker-compose --version
docker-compose version 1.26.0-rc4, build d279b7a813. Dockerfile编写(40分)
自定义Dockerfile，要求Dockerfile主要完成以下工作： ①构建一个基于Python 3.5的镜像。 ②把当前目录添加到镜像中的/code路径下。 ③把工作路径设置成/code。 ④设置容器的默认命令为python app.py。 将Dockerfile文件以文本形式提交到答题框。
[root@localhost ~]# mkdir jr
[root@localhost ~]# cd jr/
[root@localhost jr]# vim Dockerfile
# 注释：构建时用到的基础镜像
FROM python:3.5-alpine
# 注释：将该目录下的所有文件(点表示当前工作路径，也可以写路径)复制到/code下
ADD . /code
# 注释：切换工作目录为/code
WORKDIR /code
# 注释：在容器启动时执行的命令
CMD ["python", "app.py"]- 构建Dockerfile的镜像(注意后面有个点，表示文件路径我就在这个文件里面了所有用点表示,当然也可以把点换成路径)：
[root@localhost jr]# docker build -t test .

下面有一段脚本，作用是自动配置mysql服务，由于工程师的失误，将脚本中的某些代码删除了，但注释还在，请根据注释，填写代码。最后将填写的代码按照顺序以文本形式提交至答题框。 脚本如下所示： mariadb(){ cd #在数据库的my.cnf文件添加内容如下 （此处需填写） [mysqld] init_connect='SET collation_connection = utf8_unicode_ci' init_connect='SET NAMES utf8' character-set-server=utf8 collation-server=utf8_unicode_ci skip-character-set-client-handshake EOF #启动数据库 systemctl start mariadb #设置数据库root的密码为123456 mysqladmin -uroot password 123456 #创建gpmall数据库，并将gpmall.sql文件导入 mysql -uroot -p123456 << EOF （此处需填写） use gpmall source /root/gpmall.sql EOF #设置开机自启数据库 systemctl enable mariadb #重启数据库服务 systemctl restart mariadb #检查数据库是否重启成功 if [ $? -eq 0 ] then sleep 3 echo -e "\033[36m==========maridb启动成功=========\033[0m" else echo -e "\033[31mmariadb启动失败，请检查\033[0m" exit 1 fi sleep 2 }

下面有一段Python脚本，由于工程师的失误，将脚本中的某些代码删除了，但注释还在，请根据注释，填写代码。最后将填写的代码按照顺序以文本形式提交至答题框。 Python脚本如下： def get_html(url, encoding='utf-8'): # 定义headers headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36' } # 调用requests依赖包的get方法，请求该网址，返回response （此处需填写） # 设置response字符为utf-8 （此处需填写） # 返回response的文本 return response.text
response = requests.get(url, headers=headers)
