======Script d'optimisation automatique des bases======

Ce script optimise les bases de données MySQL présentes sous ''/var/lib/mysql''.

<code bash> 
  #!/bin/bash 
  
  for base in `ls -l /var/lib/mysql/|grep dr|grep -Ev "test|status|mail|dumps"|awk '{print $NF}'`
  do
  echo "use $base;" > /tmp/optmz_${base}.sql
  echo -e "OPTIMIZE TABLE \c" >> /tmp/optmz_${base}.sql
          for table in `ls -1 /var/lib/mysql/$base/*.frm|awk -F "/" '{print $6}'|awk -F "." '{print $1}'`
          do
          echo -e "$table,\c" >> /tmp/optmz_${base}.sql
          done
  echo ";" >> /tmp/optmz_${base}.sql
  cat /tmp/optmz_${base}.sql|sed "s/,;/;/g" > /tmp/optmz_${base}.sql.temp
  mv /tmp/optmz_${base}.sql.temp /tmp/optmz_${base}.sql
  done
  
  for file in `ls -1 /tmp/optmz*.sql`
  do
  mysql -u ''user'' --password=XXXXXXXX < $file #''user'' doit avoir les droits full
  done
  
  rm -f /tmp/optmz*.sql
