phpmyadmin error during installation “Empty value for 'port' specified.”

Question

I have been trying to install phpmyadmin on my digitalocean droplet using ubuntu 14.04 / mysql 5.7.12 . I have a LAMP stack with apache as the web server.

During instal

Answer 1

I solved this after I added passwords to both 'mysql' root and 'mysql' user. If you leave one or both of the two empty, you can do:

sudo -i

check:

whoami

if 'root', type:

mysql, or mysql -u root -p in case you already had a password for the root.

mysql terminal opens; then I added the passwords:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH my_sql_native_password BY 'newpassword';

And/or the same for 'user' if needed. Then once I made the passwords for my user in MySQL and phpMyAdmin identical, I was done.

Before adding the passwords I applied @William Ardilla's as well as @user5781956's advice. Perhaps only @William Ardilla's is enough.
