[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/

5、主从数据库管理(40分)
使用提供的两台虚拟机，在虚拟机上安装mariadb数据库，并配置为主从数据库，实现两个数据库的主从同步。配置完毕后，请在从节点上的数据库中执行“show slave status \G”命令查询从节点复制状态，将查询到的结果以文本形式提交到答题框。

12、Docker Compose安装(40分)
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

13、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"]

14、Shell脚本补全(40分)
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

#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
