MySQL import file from MySQL console

Here's the step:
Login to your MySQL database:

mysql -u root -p

Select the database name:

mysql>use db_name;

Import the database:

mysql>source /home/dump.sql;

ERROR 1153 (08S01) at line 75: Got a packet bigger than 'max_allowed_packet' bytes

These error message raise when i run the script like the below:

mysql -u root -p my_database < dump.sql

Then raised:

ERROR 1153 (08S01) at line 75: Got a packet bigger than 'max_allowed_packet' bytes

Googling and found:

vi /etc/my.cnf

add these line under [mysqld]

[mysqld]
# added to avoid err "Got a packet bigger than 'max_allowed_packet' bytes"
#
net_buffer_length=1000000 
max_allowed_packet=1000000000
#

Restart the mysql db:

service mysqld restart

Finally, i import the database with successfully:

mysql -u root -p my_database < dump.sql

Here's the information when i show the error log of MySQL:

Googling and fix the problem:

sudo service mysqld stop

Backup your Database:

mkdir -p /opt/database/backup/

cp -r /var/lib/mysql/* /opt/database/backup/

Adding script for recovery:

vi /etc/my.cnf

then add this line

innodb_force_recovery = 4

Restart your mysql:

service mysqld restart

Dump all tables:

mysqldump -u root -p db_name > dump.sql

Drop all databases which need recovery:

mysql>DROP TABLE table_name;

Stop MySQL:

service mysqld stop

rm -rf /var/lib/mysql/ib*

Comment out recovery script:

vi /etc/my.cnf

#innodb_force_recovery

Restart your mysql:

service mysqld restart

Restore your tables of database:

mysql -u root -p db_name < dump.sql
