Ensure Log Files are Stored on a Non-System Partition

FaibleNiveau 1Automatiséemysql

Description

MySQL log files can be set in the MySQL configuration to exist anywhere on the filesystem. It is common practice to ensure that the system filesystem is left uncluttered by application logs. System filesystems include the root (/), /var, or /usr. Fails when log_bin_basename is under /var or /usr or on the root filesystem; passes when binary logging is off. Run on the database host. Runs mysql -NBe with the client defaults: put an administrative account in ~/.my.cnf (mode 0600) or a mysql_config_editor login path, not MYSQL_PWD (see 1.4/1.6).

Méthode de vérification

Méthode d'audit: Commande shell

shell

d=$(mysql -NBe "SELECT @@global.datadir" 2>/dev/null) || exit 1; b=$(mysql -NBe "SELECT IFNULL(@@global.log_bin_basename, '')" 2>/dev/null) || exit 1; [ -n "$b" ] || { echo compliant; exit 0; }; case "$b" in /*) ;; *) b="$d/${b#./}" ;; esac; case "$b" in /var/*|/usr/*) echo "under /var or /usr: $b"; exit 0 ;; esac; m=$(df -P "$(dirname "$b")" 2>/dev/null | awk 'NR==2{print $6}'); [ -n "$m" ] || exit 1; [ "$m" = / ] && echo "on the root filesystem: $b" || echo compliant

Sortie attendue: compliant

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure

Set log_bin=<path on a dedicated, non-system partition> under [mysqld] in /etc/my.cnf (or /etc/mysql/mysql.conf.d/mysqld.cnf), then restart MySQL.
