Ensure Correct Permissions on MySQL Tablespace Files

高等級 1自動化tdsql

說明

MySQL InnoDB tablespace files (.ibd), the system tablespace (ibdata*), redo log files (ib_logfile*), and undo tablespace files should have restrictive permissions. Uses TDSQL_DATA (default /data/tdsql/data) for the instance data directory. Counts *.ibd, ibdata* and ib_logfile* files readable by other users; expected 0640, owner mysql:mysql.

檢查方式

稽核方法: Shell 指令

shell

n=0; for p in "${TDSQL_DATA:-/data/tdsql/data}"; do [ -e "$p" ] && n=$((n+1)); done; [ $n -gt 0 ] || exit 1; c=0; for p in "${TDSQL_DATA:-/data/tdsql/data}"; do [ -e "$p" ] || continue; c=$((c + $(find "$p" -type f \( -name '*.ibd' -o -name 'ibdata*' -o -name 'ib_logfile*' \) -perm /o+r -print 2>/dev/null | wc -l))); done; echo $c

預期輸出: 0
