linux Basic Configuration 


python3 Adj. linux Environment compilation and installation 
1.linux How to install software under 
  - Preferred yum Tools, convenient, self-resolving dependencies between software, automatic download and installation 
    1. Configure yum Source (that is, 1 A software warehouse, which contains 1 Heap rpm Software package) 
       You can choose Alibaba Yunyuan and Tsinghua yum Source 
       Configuration section 1 Warehouse, which contains a large number of commonly used system software 
        wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
       You also have to configure the 2 Warehouses, carrying a large number of 3 Party software ( nginx , redis , mongodb , mairadb Etc.) 
        wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

    2. You have to understand yum Warehouse directory of 
      cd /etc/yum.repos.d/    # In this directory 1 Layered repo The file will be identified and asked yum Software repository 
      
    3. Empty yum Cache, empty centos Official yum Software cache 
    
    yum clean all 
    
    4. Generate a new Alibaba Cloud yum Cache 
    yum makecache 
    
    -wget  In 1 Resources url The command of 
    -apt-get ubuntu Underneath yum
    
  - Use yum Warehouse, not only can you use the first 3 Square yum Warehouse, you can still designate the official yum Source ( Like mariadb Official database yum Source, the latest software package )
  
    
  -rpm Manual installation, you have to deal with dependencies 
  
  - Free choice of version, and can extend the 3 The installation method of square function is called source code compilation and installation

View dependent modules 


pip3 freeze > requirements.txt
# This  requirements.txt The file is python Module dependency files known to programmers

Step 1. Start the mariadb database

Configuring the yum source 


1.yum
 Configure yum Source 
 　　 yum install mariadb-server mariadb -y 
  
2. Pass yum Installed software, how to start 
  systemctl start mariadb
  # systemctl start/stop/status/restart mariadb 
  
3. Login database 
  cmd Login

Export the database of windows and import it to linux machine 


cmd Login export command 
mysqldump -uroot -p se_crm > se_crm.sql # Specifies that the database is exported to se_crm.sql In this data file, 

 Transfer to linux Import in 
 Simple use  lrzsz Tool transmission 
 Or download xftp Tools 

 Command to import data  
mariadb Installation 
yum install mariadb-server


 Mode 1 : 
1. Create 1 A se_crm Database 
create database se_crm; 
# Command to import data  
mysql -uroot -p se_crm < /opt/se_crm.sql  # Specify se_crm Database, import 1 A sql Documents  

 Mode 2 : 
 After logging in to the database, import the data with the command 
  1. Create 1 A se_crm Database 
    create database se_crm; 
  2. Switch databases 
    use se_crm;
  3. Read sql File, write to dataset 
   mareiadb>  source /opt/se_crm.sql;

Step 2: Prepare the python3 environment and the virtual environment

Compile and install python3 to solve environment variables

How to compile and install python3 under centos7

1. You must address the underlying development environment required for compilation
yum install gcc patch libffi-devel python-devel zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel -y
2. Download the coding package for python3
Decompression
wget https://www.python.org/ftp/python/3.6.7/Python-3.6.7.tar.xz
xz -d Python-3.6.7.tar.xz
tar -xf Python-3.6.7.tar

4. Enter the source folder generated by decompression
cd Python-3.6.7

5. Execute the command to compile the 3-part
Find a [configured executable file, configure], execute it, and specify the software installation location
./configure --prefix=/opt/python367/

Song 2: In the previous step, an makefile will be generated, which will be compiled and installed. Under linux, the gcc tool must be used to compile, and the command used is make
make
Song 3: This 1 step is to perform the installation, which will generate the/opt/python367 folder with all the available interpreters here
make install

6. Configure environment variables for quick use of python3
1. Get the current PATH variable and add the bin directory of python3
echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/root/bin

2. Permanently modify the value of PATH
-The first is the soft connection
-Directly modification/etc/profile, the global configuration file of the system, which will be loaded when each user logs in to the system
vim /etc/profile
Write a new PATH variable

PATH="/opt/python367/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/root/bin"


3. You have to log in again, or read this/etc/profile manually
source/etc/profile # Make the variables in this file effective

Download the virtualenvwrapper tool

virtualenvwrapper, an upgraded virtual environment tool

1. Install without activating the virtual environment
pip3 install -i https://pypi.douban.com/simple virtualenvwrapper


2. Modify the configuration file and load the virtualenvwrapper tool every time you boot up

1. Open 1 user's personal environment variable profile
Global Profile/etc/profile # Effective for each user login
User Profile ~ /.bash_profile

vim ~/. bash_profile # root will read the code in this file when logging in

2. Fill in the following information and modify it for your own python environment

export WORKON_HOME= ~/Envs # Set virtualenv's Unified 1 Management Directory
export VIRTUALENVWRAPPER_VIRTUALENV_ARGS= '--no-site-packages' # Add virtualenvwrapper parameters to create a clean and isolated environment
export VIRTUALENVWRAPPER_PYTHON=/opt/python367/bin/python3.6 # Specifies an python interpreter
source/opt/python367/bin/virtualenvwrapper. sh # Execute the virtualenvwrapper installation script

3. At this point, you can use this tool to quickly create a virtual environment

mkvirtualenv Virtual Environment Name # Create Virtual Environment
lsvirtualenv # Lists the names of virtual environments
workon Virtual Environment Name # Activate or Switch Virtual Environment
lssitepackages # lists the module information in the virtual environment, which is
cdvirtualenv # Enter Virtual Environment Home Directory
cdsitepackages # Enter the third-party module directory of virtual environment

Use the mkvirtualenv command to create a new virtual environment to start crm 


mkvirtualenv s23_crm

Copy the crm code to the linux machine 


rz  #  Speak crm Drag the project package to linux,
#  Decompression

Solve the dependent environment required by crm, django and other modules, and pymysql

Solution 1:
Stupid way, report mistakes one by one to see and solve them
pip3 install -i https://pypi.douban.com/simple django==1.11.23
pip3 install -i https://pypi.douban.com/simple pymysql
pip3 install -i https://pypi.douban.com/simple django-multiselectfield
pip3 install -i https://pypi.douban.com/simple django==1.11.23

A less stupid way:
Command for exporting python interpreter module
pip3 freeze > requirements. txt # This requirements. txt file is a module dependency file known to python programmers

Install all modules in this requirements. txt file

pip3 install-r requirements. txt # Specifies dependency file installation and reads all module information in the file
