[Huawei]ip route-static 192.168.2.0 24 12.12.12.1

43、
本地YUM源管理
使用VMWare软件启动提供的xserver1虚拟机（配置虚拟机xserver1的IP为192.168.100.11，主机名为xserver1），在虚拟机的/root目录下，存在一个CentOS-7-x86_64-DVD-1511.iso的镜像文件，使用这个镜像文件配置本地yum源，要求将这个镜像文件挂载在/opt/centos目录，请问如何配置自己的local.repo文件，使得可以使用该镜像中的软件包，安装软件。请将local.repo文件的内容和执行yum repolist的返回结果以文本形式提交到答题框。

[root@xserver1 ~]# vi /etc/yum.repos.d/local.repo

[centos]

name=centos

baseurl=file:///opt/centos

gpgcheck=0

enabled=1

[root@xserver1 ~]# yum repolist

Loaded plugins: fastestmirror

centos | 3.6 kB 00:00:00

(1/2): centos/group_gz | 155 kB 00:00:00

centos centos 3,723

repolist: 3,723

44、
FTP安装使用
使用xserver1虚拟机，安装ftp服务，并配置ftp的共享目录为/opt。使用VMWare软件继续启动提供的xserver2虚拟机（配置虚拟机xserver2的IP为192.168.100.12，主机名为xserver2），并创建该虚拟机的yum源文件ftp.repo使用xserver1的ftp源（配置文件中的FTP地址使用主机名）。配置完成后，将xserver1节点执行netstat -ntpl命令（netstat命令若不能用，则自行安装net-tools工具）的返回结果和将xserver2节点的ftp.repo文件以文本形式提交到答题框。

[root@xserver1 ~]# netstat -ntpl

45、
NFS服务管理
使用xserver1、xserver2虚拟机，安装NFS服务所需要的软件包，将xserver1节点中的/mnt/share目录使用NFS服务共享出来（目录不存在请自行创建，要求可访问共享目录的网段为192.168.100.0/24），接着在xserver2节点上，将xserver1中共享的文件挂载到/mnt目录下。操作完毕后，依次将xserver1节点上执行showmount -e ip命令和xserver2节点上执行df -h命令的返回结果以文本形式提交到答题框。

[root@xserver1 ~]# showmount -e 192.168.100.11

Export list for 192.168.100.11:

46、
主从数据库管理
在xserver1、xserver2上安装mariadb数据库，并配置为主从数据库（xserver1为主节点、xserver2为从节点），实现两个数据库的主从同步。配置完毕后，请在xserver2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。

LNMP环境部署
使用xserver1节点，安装单节点lnmp环境。安装lnmp环境需要用到的YUM源为CentOS-7-x86_64-DVD-1511.iso和lnmp目录（均在/root目录下）。安装并配置完lnmp环境后。依次查询数据库、nginx、php服务的状态，并使用netstat -ntpl命令查看端口开放情况。最后依次将查询服务状态的返回结果，和查看端口开放情况的返回结果以文本形式提交到答题框。

OpenStack Keystone管理
使用VMWare软件启动提供的opensatckallinone镜像，自行检查openstack中各服务的状态，若有问题自行排查。在keystone中创建用户testuser，密码为123456，创建好之后，查看testuser的详细信息。将上述所有操作命令及返回结果以文本形式提交到答题框。

[root@controller ~]# source /etc/keystone/admin-openrc.sh

OpenStack Glance管理
使用VMWare软件启动提供的opensatckallinone镜像，自行检查openstack中各服务的状态，若有问题自行排查。在xserver1节点的/root目录下存在一个cirros-0.3.4-x86_64-disk.img镜像；使用glance命令将镜像上传，并命名为mycirros，最后将glance image-show id命令的返回结果以文本形式提交到答题框。

Docker安装
使用xserver1节点，自行配置YUM源，安装docker服务（需要用到的包为xserver1节点/root目录下的Docker.tar.gz）。安装完服务后，将registry_latest.tar上传到xserver1节点中并配置为私有仓库。要求启动registry容器时，将内部保存文件的目录映射到外部的/opt/registry目录，将内部的5000端口映射到外部5000端口。依次将启动registry容器的命令及返回结果、执行docker info命令的返回结果以文本形式提交到答题框。

[root@xserver1 ~]# docker run -d -v /opt/registry:/var/lib/registry -p 5000:5000 --restart=always --name registry registry:latest

54、
Dockerfile编写
使用xserver1节点，新建目录centos-jdk，将提供的jdk-8u141-linux-x64.tar.gz复制新建的目录，然后编辑Dockerfile文件，文件要求如下：

1.使用centos:latest基础镜像；

2.指定作为为xiandian；

3.新建文件夹/usr/local/java用于存放jdk文件；

4.将JDK文件复制到镜像内创建的目录并自动解压；

5.创建软连接：ln -s /usr/local/java/jdk1.8.0_141 /usr/local/java/jdk；

6.设置环境变量如下

ENV JAVA_HOME /usr/local/java/jdk

ENV JRE_HOME ${JAVA_HOME}/jre

ENV CLASSPATH .:${JAVA_HOME}/lib:${JRE_HOME}/lib

ENV PATH ${JAVA_HOME}/bin:$PATH

编写完毕后，构建名为centos-jdk的镜像，构建成功后，查看镜像列表。最后将Dockerfile的内容、构建镜像的操作命令、查看镜像列表的命令和返回的结果以文本形式提交到答题框。

[root@xserver1 centos-jdk]# vi Dockerfile

部署K8S集群
使用xserver1、xserver2节点，自行配置好网络，安装好docker-ce。部署K8S 集群，不要求部署kubernetes-dashboard。部署K8S平台完成后，在主节点使用命令依次检查集群状态、Pods状态、各节点的状态。最后将检查状态的命令及返回结果以文本形式提交到答题框。
