Using SQLite3 with Django 2.2 and Python 3.6.7 on Centos7

Question

I am moving my Django code from 2.1.7 directly to the new Django 2.2. The only problem I encountered in my Centos7 development environment was that my local development databas

Answer 1

I am using Centos7 with python36.

[shmakovpn@localhost ~]$ ldd /usr/lib64/python3.6/lib-dynload/_sqlite3.cpython-36m-x86_64-linux-gnu.so
linux-vdso.so.1 =>  (0x00007ffcafdf6000)
libsqlite3.so.0 => /lib64/libsqlite3.so.0 (0x00007f0adf439000)
libpython3.6m.so.1.0 => /lib64/libpython3.6m.so.1.0 (0x00007f0adef10000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f0adecf4000)
libc.so.6 => /lib64/libc.so.6 (0x00007f0ade927000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007f0ade723000)
libutil.so.1 => /lib64/libutil.so.1 (0x00007f0ade520000)
libm.so.6 => /lib64/libm.so.6 (0x00007f0ade21e000)
/lib64/ld-linux-x86-64.so.2 (0x00007f0adf903000)

This means that python36 uses /lib64/libsqlite3.so.0 In python console it looks like this

>>> import sqlite3
>>> sqlite3.version
'2.6.0'
>>> sqlite3.sqlite_version
'3.7.17'

Needs to replace the library, so we must have a new version of it. There are one of way how to do this.

wget http://www6.atomicorp.com/channels/atomic/centos/7/x86_64/RPMS/atomic-sqlite-sqlite-3.8.5-3.el7.art.x86_64.rpm
sudo yum localinstall atomic-sqlite-sqlite-3.8.5-3.el7.art.x86_64.rpm
sudo mv /lib64/libsqlite3.so.0.8.6{,-3.17}
sudo cp /opt/atomic/atomic-sqlite/root/usr/lib64/libsqlite3.so.0.8.6 /lib64

Go to python console once again

>>> import sqlite3
>>> sqlite3.sqlite_version
'3.8.5'

Now it looks much better. Let's try to create Django project and apply migrations

django-admin startproject sqlite3test
cd sqlite3test/
python manage.py migrate
    Operations to perform:
        Apply all migrations: admin, auth, contenttypes, sessions
    Running migrations:
        Applying contenttypes.0001_initial... OK
        ... and so on
ls -al | grep db
