AWS RDS - Give Superuser Privileges to Regular mysql User

Login as super user on command prompt.

Run following query to give superuser privileges to normal user.

GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, PROCESS, REFERENCES, INDEX, ALTER, SHOW DATABASES, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER ON *.* TO 'username'@'%' WITH GRANT OPTION;

Just change username in above query and execute as root user. Your regular user will be a super user now.

Wordpress Permissions - Upload plugin using wp-admin

Upload plugin using wp-admin without ftp.

If you are not able to install plugin using wp-admin because of forbidden error or a permission issue, you simply change the permission of whole wordpress directory to fix it. That is very dangerous and a common security loophole.

Here is the minimum permission for your plugin directory which is enough to instal plugin using wp-admin.

Give 777 to wp-content/plugins and wp-content/upgrade Non-Recursively. It will allow admin to install plugin using wp-admin.

postgresql error : ERROR: database is being accessed by other users

ERROR:  database "X" is being accessed by other users
DETAIL:  There is 1 other session using the database

Solution :

SELECT pg_terminate_backend(pid) FROM pg_stat_activity WHERE pid <> pg_backend_pid() AND datname = 'database-name';

You need to replace only database name in above query.

Now you can drop the database or perform other activity what you were trying to perform.
