I realize that I forgot to create a PostgreSQL, so I used pgAdmin4.28 to create a "wiki" database. Error now changed to:

Please send help! I appreciate all comments. Thanks!

Answer 1

I had similar issue with postgres and wiki.js.
Solution was to manually create the Database in postgres, BEFORE you run node server:
CREATE DATABASE wiki
Hope that saves you the time I had to spend to figure this out.

You just need to config.yml The database configuration in is modified as follows:
db:
type: postgres
# PostgreSQL / MySQL / MariaDB / MS SQL Server only:
host: localhost
port: 5432
user: postgres #YOU PostgreSQL USERNAME
pass: willasas#wiki. #YOU PostgreSQL PASSWORD
db: wiki #YOU DATABASE NAME
ssl: false
Then run the code
node server
And type in the address bar of your browser http://127.0.0.1 : 3000 / parallel return

Answer 3

After a couple hours of testing I realized some problems using postgres in wiki.js. These are some recommendations you can try in config.yml:
db:
type: postgres
# if you are using docker try using IP instead of localhost
host: localhost
port: 5432
# don't use _ here. It'll cause connection error undefined.
user: wikijs
# start with letter, if you start with # it will throw an error.
# I used a 18 long pass without any problem. Ex:
pass: wiki#projectW777!#
# you can use _ here. Ex:
db: prj_wiki

Answer 4

If you need to change the database password, this can help you:
ALTER USER postgres WITH PASSWORD 'xxx';

Answer 5

I had the same problem:
error: Database Connection Error: 28P01 undefined:undefined
I've solved it by modifying 86 line of file /var/lib/psql/data/pg_hba.conf, changing ident to md5 and then restarted database:
$ sudo systemctl restart postgresql
Additionally I've changed password in database:
$ sudo -u wikijs psql -d wiki
wiki=# \password wikijs
After that I've successfully executed node server.

Answer 6

Use this docker-compose file.
It solved my problems. Also make sure all the service names are unique, i.e. neither of the exist in your presently running docker containers
version: '3'
services:
db:
image: mysql:8.0
logging:
driver: "none"
restart: unless-stopped
volumes:
- db-data:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: mysql123!
MYSQL_DATABASE: wiki
wiki:
image: requarks/wiki:2
depends_on:
- db
environment:
DB_TYPE: mysql
DB_HOST: db
DB_PORT: 3307

DB_PASS: mysql123!
