Ensure Log Files are Stored on a Non-System Partition

低レベル 1自動mysql

説明

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).

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

期待される出力: compliant

修正方法

修正方法: ガイダンスまたは IaC パッチ

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.
