一、Minimal安裝
1.1 下載安裝文件源 http://mirrors.aliyun.com/centos/7/isos/x86_64/CentOS-7-x86_64-Minimal-1908.iso
1.2 新建Hyper-v第二代虛擬機?過程略......,安裝完畢!!
注意:虛擬機設置別勾選"啟用安全啟動",其他選項默認
二
、
修
改
yum源(阿里 )
2.1? 備份原yum源配置文件? mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo_bak
2.2 .獲取阿里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? 獲取阿里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 查看更新結果 yum repolist enabled&&yum repolist all
三、安裝MAN中文?
????3.1?安裝MAN中文 包 yum install man-pages-zh-CN.noarch (查看包名稱 yum list |grep man.*zh)
????3.2 編輯配置文件使MAN中文包生效?
????????1 全局所有用戶生效?echo alias cman=\'man -M /usr/share/man/zh_CN\'>> /etc/bashrc && source /etc/bashrc
????????2 當前有用戶生效?echo alias cman=\'man -M /usr/share/man/zh_CN\'>> ~/.bashrc && source ~/.bashrc
四、升級python2為python3( 默認)
? ? 4.1 下載安裝文件到用戶根目錄(單線程有慢) wget -P ~ https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tgz
? ??4.2 安裝依賴包?yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc libffi-devel
????4.3? 解壓文件并進入目錄 tar -xf ~/Python-3.7.5.tgz&&cd ~/Python-3.7.5
? ? 4.4 編譯安裝 mkdir /usr/local/python3?&& ./configure --prefix=/usr/local/python3 && make && make install
? ? 4.5 備份python2后改python3為默認?mv /usr/bin/python /usr/bin/python2bak && ln -s /usr/local/python3/bin/python3.7 /usr/bin/python
? ? 4.6 建pip3軟連接 ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3(或改pip默認為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)文件頭將 #!/usr/bin/python 改為 #!/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 用戶環境安裝包 pip3 install --user dotmap
五、其他配置
? ?5.1??.bash_profile
????????alias ll='ls -aslht'
????????alias cls='clear'
????????PATH=$PATH:$HOME/.local/bin:$HOME/bin
????????export PATH
????????export PYTHONPATH=$HOME/.local/lib/python3.7/site-packages
????????export TIME_STYLE='+%Y-%m-%d %H:%M:%S'
????????export HISTTIMEFORMAT='%F %T '
????????export PS1='\D{%F %T} \u@\h$0 \v$PWD(\#)\$'
