Synchronize two databases schema in MySQL

Question

I was looking for a portable script or command line program that can synchronize two MySQL databases schema. I am not looking for a GUI based solution because that can\'t be aut

Answer 1

I know it's an old question but it was the first result on google for what I was searching for (exact same thing as the initial question)

I found the answer still here but I don't remember the URL it's a script that started from:

mysqldump --skip-comments --skip-extended-insert -u root -p dbName1>file1.sql
mysqldump --skip-comments --skip-extended-insert -u root -p dbName2>file2.sql
diff file1.sql file2.sql

and ended up more like this

#!/bin/sh

echo "Usage: dbdiff [user1:pass1@dbname1] [user2:pass2@dbname2] [ignore_table1:ignore_table2...]"

dump () {
  up=${1%%@*}; user=${up%%:*}; pass=${up##*:}; dbname=${1##*@};
  mysqldump --opt --compact --skip-extended-insert -u $user -p$pass $dbname $table > $2
}

rm -f /tmp/db.diff

# Compare
up=${1%%@*}; user=${up%%:*}; pass=${up##*:}; dbname=${1##*@};
for table in `mysql -u $user -p$pass $dbname -N -e "show tables" --batch`; do
  if [ "`echo $3 | grep $table`" = "" ]; then
    echo "Comparing '$table'..."
    dump $1 /tmp/file1.sql
    dump $2 /tmp/file2.sql
    diff -up /tmp/file1.sql /tmp/file2.sql >> /tmp/db.diff
  else
    echo "Ignored '$table'..."
  fi
done
less /tmp/db.diff
rm -f /tmp/file1.sql /tmp/file2.sql
