RECOVER MYSQL. IF MYSQL COULD NOT BE STARTED

1)The MySQL database is configured to use InnoDB engine by default.

You can add the innodb_force_recovery=1 option in the main MySQL configuration file at /opt/bitnami/mysql/etc/my.cnf to try and fix the database:

                [mysqld]
          innodb_force_recovery = 1

2) Start the MySQL database with the following command:

 mysqld --skip-grant-tables --user=mysql --skip-external-locking --port=3306 --sock=/opt/bitnami/mysql/tmp/mysql.sock

3)mysql -u root -p

4)o not forget to remove the innodb_force_recovery option from the my.cnf file and restart the MySQL server again

5)If they show any permission issue use

 sudo chown mysql:root -R /opt/bitnami/mysql/data chmod 1777 /tmp

To find error logs:

 cd /var/log/apache2

Disk space issue- Linux commands

To know disk space

df -h

follow a top-down approach by looking at the inode count for each main folder, and then drill down to the directory that consumes the most inodes

find /var -xdev -printf '%h\n' | sort | uniq -c | sort -k1 -rn

Once we know the top folders that contributed to the disk overage, we can then drill down to weed out those that are not needed.

du -hm --max-depth=1 | sort -kl,l -nr

cd /opt/bitnami/magento/htdocs

sudo rm -rf var/cache/*

sudo rm -rf var/log

sudo rm -rf var/page_cache/*

sudo /opt/bitnami/ctlscript.sh start

bitnami@ip-172-31-88-222:/opt/bitnami/mysql$ sudo chown mysql:root -R /opt/bitnami/mysql/data
