If you plan to to upgrade using the data directory from your existing:

  1. MySQL installation:

  2. Stop the old (MySQL 5.6) server

  3. Upgrade the MySQL binaries in place (replace the old binaries with the new ones)

  4. Start the MySQL 5.7 server normally (no special options)

  5. Run mysql_upgrade to upgrade the system tables

  6. Restart the MySQL 5.7 server

Installing MySQL from Source

# refer MySQL-5.7 installation-tutorial.

Backup old MySQL

#tar zcvf mysql.tar.gz /usr/local/mysql
service mysqld stop
cd /usr/local/
mv mysql mysql5.6

Replace the binaries

#mv /usr/local/mysql-5.7.19 /usr/local/mysql
#ln -s  /usr/local/mysql/bin /usr/local/bin/
#unlink /usr/local/mysql
ln -s mysql-5.7.19/ mysql
chown -R mysql:mysql mysql-5.7.19/
