安装docker

centos7

一、安装前必读在安装 Docker 之前，先说一下配置，我这里是Centos7

Linux 内核：官方建议 3.10 以上，3.8以上貌似也可。

习Linux是很痛苦的过程，不计其数的linux学习者前期开启虚拟机双系统，中期实体机Linux，但在后期投入了MacOS的怀抱或者回到了梦开始的地方–虚拟机。

虚拟机除了性能差点，其余可谓是和实体机没什么差别，但直接在虚拟机内操作可能体验感比较差，要不，我们用ssh远程连接虚拟机的终端吧！

准备工作详细的安装步骤略。我使用的是VMware Workstation Pro 16.0安装了Ubuntu 20.04LST 默认虚拟机的网络适配器是NAT模式，因为学校的校园网登录需要认证，我就让它保持不变。然后就是要知道宿主机和虚拟机的ip地址

宿主机 Windows 10


	解决办法：在列写入值的时候，在值的前后加上"\t"，记住一定要双引号。


	$excel->setActiveSheetIndex(0)->setCellValue("A" . $i,"\t". $v['pk_name']."\t")
	->setCellValue("B" . $i, "\t". $order_name."\t")
	->setCellValue("C" . $i, "\t". $v['order_real_price']."\t")
	->setCellValue("D" . $i, "\t". $v['order_username']."\t")
	->setCellValue("E" . $i, "\t". $v['order_user_phon']."\t")
	->setCellValue("F" . $i, "\t". $v['order_id_num']."\t")

	server {
	listen 80;
	server_name www.zlmm.cc; # 虚拟机域名
	root /usr/share/nginx/html/zlmm;
	index index.php index.html index.htm;
	#charset koi8-r;

	access_log /dev/null;

	查看版本信息
	[root@ganbing ~]# cat /etc/redhat-release
	CentOS Linux release 7.4.1708 (Core)
	[root@ganbing ~]# docker version
	Client:
	Version: 17.12.0-ce

	First of all, we have to start the docker container

	ankit@ankit-HP-Notebook:~$ sudo docker start 3a19b39ea021

	3a19b39ea021
	After that, check the docker container:

	ankit@ankit-HP-Notebook:~$ sudo docker ps -a

	CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

	CentOS下yum命令出现Loaded plugins: fastestmirror

	fastestmirror是yum的一个加速插件，这里是插件提示信息是插件不能用了。
	步骤：

	1.修改插件的配置文件
	# vi /etc/yum/pluginconf.d/fastestmirror.conf
	【Tips】：用Tab可补全
	将enabled=1改为enabled=0

	Disclaimer:
	Before installing and using Telnet, keep the following in mind.

	Using Telnet in public network(WAN) is very very bad idea. It transmits login data in the clear format. Everything will be sent in plain text.
	If you still need Telnet, It is highly recommended use it in the local area network only.
	Alternatively, you can use SSH. But make sure you’ve disabled root login in SSH.
	What Is Telnet?
	Telnet is a network protocol which is used to connect to remote computers over TCP/IP network. Once you establish a connection to the remote computer, it becomes a virtual terminal and will allow you to communicate with the remote host from your local system.

	In this brief tutorial, let us see how to install Telnet, and how to access remote systems via Telnet.

	# 这两条命令设置开机时自动启动telnet服务
	systemctl enable telnet.socket
	systemctl enable xinetd

	# 启动telnet服务
	systemctl start telnet.socket
