Upgrade sqlite3 version

It is recommended to do this step before installing python3.9.5 Download the source code wget https://www.sqlite.org/2019/sqlite-autoconf-3300100.tar.gz unzip, compile tar zxvf sqlite-autoconf-3290000.tar.gz cd sqlite-autoconf-3290000/ ./configure --prefix=/usr/local make && make install Replace system low version sqlite3 mv /usr/bin/sqlite3 /usr/bin/sqlite3_old ln -s /usr/local/bin/sqlite3 /usr/bin/sqlite3 echo "/usr/local/lib" > /etc/ld.so.conf.d/sqlite3.conf ldconfig sqlite3 -version

Check python version

python3

  • If the python version is not 3.9.5, please execute the following command

cd /usr/src wget https://www.python.org/ftp/python/3.9.5/Python-3.9.5.tgz tar -zxvf Python-3.9.5.tgz cd Python-3.9.5/ ./configure --enable-optimizations make altinstall mv /usr/bin/python3 /usr/bin/python3.bak ln -s /usr/local/bin/python3.9 /usr/bin/python3 mv /usr/bin/pip3 /usr/bin/pip3.bak ln -s /usr/local/bin/pip3.9 /usr/bin/pip3

Check pip3 list is installed successfully

pip3 list

install git

yum install git

Download GreaterWMS from gitee

git clone https://github.com/Singosgu/GreaterWMS.git

Elevate GreaterWMS Folder

chmod -R 755 GreaterWMS

Go to the GreaterWMS folder

cd GreaterWMS>pip3 install -r requirements.txt

  • Sometimes, there will be problems when you install these libraries because of the python3 version, don't worry, pip3 install the wrong library.

Ctrl + C

database generation

python3 manage.py makemigrations // database generation

database migration

python3 manage.py migrate // database migration

/usr/local/bin/daphne -b 0.0.0.0 -p 8008 greaterwms.asgi:application

  • Now open your browser, type "your external ip :8008" and you will see the project is running

Go back to the GreaterWMS folder

Ctrl + C cd templates

Wait for the Yarn installation to complete. In fact, you can also npm install it, but it will be slower Change yarn to domestic source

/usr/local/bin/yarn install

Start the front-end page with the quasar command

/usr/local/bin/quasar d

  • The front end will send a request to "127.0.0.1:8008", here we just check if the project can run

Go back to the baseurl folder

Ctrl + C // go back to templates folder

Example changes before

const baseurl = 'http://127.0.0.1:8008/' const wsurl = 'ws://127.0.0.1:8008/'

Example changes after

const baseurl = 'https://{ your external ip }/' const wsurl = 'ws://{ your external ip }/'

  • Press Esc and type ":wq" to save changes
  • Now, you know how to deploy and modify the request address

back to templates

you should build it again

cd templates /usr/local/bin/quasar build

Go back to the GreaterWMS folder

cd .. /usr/local/bin/daphne -b 0.0.0.0 -p 8008 greaterwms.asgi:application - Now, open the browser, type "your external IP: 8008", you can see the project is running
