二、问题

1.MobaXterm设置右键复制粘贴

（1）点击设置

（2）终端

取消右键粘贴

2.OpenEuler如何查看CPU的核数

（1）查看CPU的核数

1)CPU总核数 	= 物理CPU个数 * 每颗物理CPU的核数 

2)逻辑CPU总数 = 物理CPU个数 * 每颗物理CPU的核数 * 超线程数

3)多核超线程：
			1>多个物理CPU：	物理CPU间通过总线进行通信，效率比较低。
			1>多核CPU：		不同的核通过L2 cache进行通信，存储和外设通过总线与CPU通信。
			2>超线程：		每个核有两个逻辑的处理单元，两个处理单元共享一个核的资源。

（2）查看

#查看CPU的型号
cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
		
#查看物理CPU的个数
cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l

#查看每颗物理CPU的核数
cat /proc/cpuinfo| grep "cpu cores"| uniq

#查看逻辑CPU的个数
cat /proc/cpuinfo| grep "processor"| wc -l

#计算超线程数：
逻辑CPU/CPU总核数 
# 8/(2*4)=1

3. Web 浏览器不显示 htdocs 目录中的 index.html

（1）报错

（2）原因分析

查看版本，系统更新默认dnf 安装了 httpd ,所以默认配置文件在 /etc/httpd/conf/httpd.conf

[root@localhost httpd-2.4.58]# httpd -v

查看配置文件，此为dnf安装的配置文件

[root@localhost httpd-2.4.58]# sudo vim /usr/lib/systemd/system/httpd.service

# See httpd.service(8) for more information on using the httpd service.

# Modifying this file in-place is not recommended, because changes
# will be overwritten during package upgrades.  To customize the
# behaviour, run "systemctl edit httpd" to create an override unit.

# For example, to pass additional options (such as -D definitions) to
# the httpd binary at startup, create an override unit (as is done by
# systemctl edit) and enter the following:
