安裝軟體

rpm

# 安裝
rpm -ivh wget-1.12-10.el6.i686.rpm
# 幹掉
rpm -e wget

yum 安裝

設定映象源

1、備份

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2、下載新的CentOS-Base.repo 到/etc/yum.repos.d/

CentOS 5

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
 

或者

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo

CentOS 6

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

或者

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

CentOS 7

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
 

或者

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

3、之後執行yum makecache生成快取

yum makecache

安裝命令

yum [-y] install wget
yum [-y] remove wget

Python3安裝

1. 安裝開發工具包

   # 安裝開發工具
   yum groupinstall "development tools" 
   # 裝一些依賴包
   yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel expat-devel
    
   

2. 下載python3壓縮包

   # https://www.python.org/downloads/release/python-363/ 有下載地址
   wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz
   # 或者在windnows下下載好，拉到linux中
   

3. 解壓

   # 解壓檔案
   tar -xvf Python-3.6.3.tgz
   # 進入到目錄
   cd Python-3.6.3
   

4. 原始碼安裝 三步走

   # 配置
   ./configure --enable-optimizations --prefix=/usr/local/python
   # 編譯
   make
   #安裝
   make install
   # 可以合成一步 make && make install
   

5. 如何執行python3

   # 第一種方式 建立軟連線
   ln -s /usr/local/python/bin/python3.6 /usr/bin/python3
   ln -s /usr/local/python/bin/pip3 /usr/bin/pip3
   
   # 設定成 /usr/local/python/bin 設定成環境變數
   vim /etc/profile
   export PATH=新新增的路徑:$PATH
   source /etc/profile
   

virtualenv 使用

1. 安裝

   pip3 install virtualenv
   

2. 建立

   virtualenv –p /usr/local/python/bin/python3.6 shop
   

3. 啟用 讓虛擬環境生效

   source /root/shop/bin/activate
   

4. 退出

   deactivate
   

ipython 安裝

pip3 install ipython

python安裝簡化版

1. 安裝gcc

   yum install gcc
   # 裝一些依賴包
   yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel expat-devel
   

2. 下載安裝包

   wget https://www.python.org/ftp/python/3.6.7/Python-3.6.7.tgz
   

3. 解壓

   tar -xvf Python-3.6.7.tgz
   cd Python-3.6.7
   

4. 原始碼安裝三步走

   # 配置
   ./configure --prefix=/usr/local/python
   # 編譯
   make
   #安裝
   make install
   # 可以合成一步 make && make install
   

5. 設定環境變數

   # 設定環境變數
   vim /etc/profile
   export PATH=新新增的路徑:$PATH
   source /etc/profile
   

6. 安裝ipython

   pip2 install ipython
   

命令補充

# 切換到codewen使用者
su codewen
# 回到root使用者
su
# 檢視當前使用者
whoami
