Hyper-v第二代虚拟机安装CentOS7

1.1 下载安装文件源 http://mirrors.aliyun.com/centos/7/isos/x86_64/CentOS-7-x86_64-Minimal-1908.iso

1.2 新建Hyper-v第二代虚拟机过程略......,安装完毕!!

注意:虚拟机设置别勾选"启用安全启动",其他选项默认

2.1 备份原yum源配置文件 mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo_bak

2.2 .获取阿里yum源配置文件 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

2.3 获取阿里epel置文件 wget -O /etc/yum.repos.d/epel-7.repo http://mirrors.aliyun.com/repo/epel-7.repo

2.4 清理更新源配置 yum clean all && yum makecache

2.6 查看更新结果 yum repolist enabled&&yum repolist all

3.1 安装MAN中文包 yum install man-pages-zh-CN.noarch (查看包名称 yum list |grep man.*zh)

3.2 编辑配置文件使MAN中文包生效

1 全局所有用户生效 echo alias cman=\'man -M /usr/share/man/zh_CN\'>> /etc/bashrc && source /etc/bashrc

2 当前有用户生效 echo alias cman=\'man -M /usr/share/man/zh_CN\'>> ~/.bashrc && source ~/.bashrc

4.1 下载安装文件到用户根目录(单线程有慢) wget -P ~ https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tgz

4.2 安装依赖包 yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc libffi-devel

4.3 解压文件并进入目录 tar -xf ~/Python-3.7.5.tgz&&cd ~/Python-3.7.5

4.4 编译安装 mkdir /usr/local/python3 && ./configure --prefix=/usr/local/python3 && make && make install

4.5 备份python2后改python3为默认 mv /usr/bin/python /usr/bin/python2bak && ln -s /usr/local/python3/bin/python3.7 /usr/bin/python

4.6 建pip3软连接 ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3(或改pip默认为pip3: ln -s /usr/local/python3/bin/pip3 /usr/bin/pip)

4.7 修改yum及urlgrabber-ext-down配置(只能使用python2)文件头将 #!/usr/bin/python 改为 #!/usr/bin/python2

sed -i '1c #!/usr/bin/python2' /usr/bin/yum

sed -i '1c #!/usr/bin/python2' /usr/libexec/urlgrabber-ext-down

4.8 用户环境安装包 pip3 install --user dotmap

5.1 .bash_profile

alias ll='ls -aslht'
