Automate recovery from Innodb pages

Requirements

• RedHat Linux (for now, tested)

git clone https://github.com/VanagaS/mysql-innodb-autorecover.git
cd mysql-innodb-autorecover
pip install -e . 

pip should be running with python 3.8. On some systems, it could be pip3 or pip3.8 etc

unless run with sudo pip would install binary mysql_innodb_autorecover under $HOME/.local/bin/. Make sure the PATH variable has this directory, else do

export PATH=$HOME/.local/bin:$PATH

Run

mysql_innodb_autorecover -u <Username> -H <Hostname> -D <DB Name> -r /tmp/recovered -d /var/lib/mysql 

• -r /tmp/recovered: Whatever recovered, can be found under /tmp/recovered/<table-name> as tsv files
• -d /var/lib/mysql: MySQL data directory. Unless running with sudo, make sure to have access permissions to this directory or make a copy of it and refer to the path of the copy
