Ensure Log Files are Stored on a Non-System Partition

低等級 1自動化mysql

說明

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).

檢查方式

稽核方法: Shell 指令

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

預期輸出: compliant

修補方式

修補方法: 操作指南或基礎設施修補檔

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.
