Environmental installation

Foreplay

Basic knowledge needed:

• Network configuration: Reference resources
• Share path: Reference resources

Required software & Image

• VirtualBox: the best free virtual machine software

The download address is as follows (install the software suitable for your own operating system):
https://www.virtualbox.org/wiki/Downloads

• Vagrant: that's the tool we need to create and manage virtual machines

The download address is as follows (install the software suitable for your own operating system):
http://downloads.vagrantup.com/

• System image: it is provided to vagrant to create (I understand this is special, because the suffix after file download is. box instead of. iso)

http://www.vagrantbox.es/
Select a system image that you want, for example, I use CentOS 7.2 pure version, and then I can download it from Xunlei or direct browser at the following address
https://github.com/CommanderK5/packer-centos-template/releases/download/0.7.2/vagrant-centos-7.2.box

Environmental preparation

Install these two programs under windows:
vagrant
virtualbox

Directory preparation

• Software installation path
• Development environment configuration path

D:\>cd study
D:\study>cd devops-8
D:\study\devops-8>cd data
D:\study\devops-8\data>vagrant box list
centos7-dev (virtualbox, 0)
centosbox (virtualbox, 0)
D:\study\devops-8\data>vagrant init centos7-dev     #Initialize the environment path and generate the Vagrantfile configuration file

Modify the Vagrantfile configuration file

#Change port mapping to 8000
config.vm.network "forwarded_port", guest: 80, host: 8000

Start virtual machine

D:\study\devops-8\data>vagrant up
 Image exists in:
C:\Users\wanghui\.vagrant.d\boxes\centos7-dev\0

Login virtual machine

user:vagrant
pass:vagrant
host:127.0.0.1
port:2222

Synchronous directory

==> default: Mounting shared folders...
default: /vagrant => D:/study/devops-8/data

Software installation

django support version: 1.11

time synchronization

cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime      ，Time zone setting;
timedatectl status                                                ，Check the time synchronization status;
yum install ntp -y
timedatectl set-ntp true                                      ，Turn on network time synchronization;

Configure yum

yum -y install gcc gcc-c++ openssl openssl-devel vim net-tools wget zip unzip lrzsz 
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

Install Python

yum -y install openssl-devel readline-devel unzip #Solution dependence
wget https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz 
tar xf Python3.6.6.tgz
cd Pyrthon3.6.6
# configure
./configure --enable-optimizations
# vim Modules/Setup release the following configuration
_ssl _ssl.c \
        -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
        -L$(SSL)/lib -lssl -lcrypto
#install
make altinstall

Modify pip configuration

# tee /etc/pip.conf <<EOF
[global]
index-url = http://pypi.douban.com/simple
trusted-host = pypi.douban.com
[list]
format=columns
EOF

Install virtualenv and initialize the environment

pip3.6 install virtualenv
su - vagrant
cd /home/vagrant
virtualenv -p /usrlocal/bin/python3.6 venv3
source venv3/bin/activite
pip3 install "django>=1.11,<2.0"

Install & configure database

yum -y install mariadb mariadb-server mariadb-devel
# vim /etc/my.cnf configuration
[mysqld]
port = 3306
default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci
init-connect = 'SET NAMES utf8'
character-set-server = utf8
[mysql]
default-character-set=utf8

-----Service startup-----
systemctl start mariadb
systemctl enable mariadb

-----Initialize configuration-----
mysql_secure_installation #Password set to 123456

------install python-mysql Plug-in unit------
[vagrant@localhost ~]$ source /home/vagrant/venv3/bin/activate
pip3 install mysqlclient

------Create database-------
mysql -uroot -p123456 -e "create database devops CHARACTER SET utf8;"
