Amazon RDSでMySQLTunerを使用する方法
MySQLTuner をローカルにインストールしましたが、ローカルデータベースで動作します。
実行していないAmazon RDSデータベースで実行しようとすると、ログイン認証情報が無効であると表示されます。
$ Perl mysqltuner.pl --Host testing-db.??????????.us-east-1.rds.amazonaws.com --port 3306 --user admin_un --password admin_pw --forcemem 7500
[--] Performing tests on testing-db.??????????.us-east-1.rds.amazonaws.com:3306
[!!] Attempted to use login credentials, but they were invalid
通常はローカルでRDSデータベースにmyssqlを付けることができます。
mysql -h testing-db.??????????.us-east-1.rds.amazonaws.com -P 3306 -u admin_un -p
ここで何が欠けているのでしょうか？
[〜＃〜]更新[〜＃〜]
DBは、2つのvCPUと7.5GiBのRAMを備えた AWS RDS db.m3.large インスタンス上にあります。 AWSコンソールからのRDSパラメータグループで、推奨されるMySQL構成設定 here を構成しました。

バージョン：5.6.23-log
7.5 GBのRAM
稼働時間= 02:09:14;数時間後にSHOW GLOBAL STATUSを再実行してください。
Windowsで実行していません。
64ビットバージョンの実行
InnoDBを完全に（またはほとんど）実行しているようです。
重要なアイテム
tmp_table_size = 64M
インデックスとクエリの定式化を確認します-多くは（tmpテーブルなどを使用して）非効率に見えます
いたずらなクエリを特定するのに役立つように、long_query_time = 2を設定し、スローログをオンにすることをお勧めします。
レプリケーションはオンになっていますが、binlogは永久に保持されていますか？または、RDSは私が知らない方法でそれらをパージしますか？.
詳細
（Innodb_buffer_pool_pages_free * 16384/innodb_buffer_pool_size）= 346,833 * 16384/5705302016 = 99.6％-空きバッファープールの割合-buffer_pool_sizeがワーキングセットよりも大きい;それを減らすことができます（重要ではありません）
（稼働時間/ 60 * innodb_log_file_size/Innodb_os_log_written）= 7,754/60 * 128M/7059968 = 2,456-InnoDBログローテーション間の分5.6.8以降、これは動的に変更できます。 my.cnfも必ず変更してください。 -（ローテーション間の60分の推奨はやや恣意的です。）innodb_log_file_sizeを調整します。 -サーバーでのアクティビティが非常に少ない
（tmp_table_size）= 265M-SELECTのサポートに使用される[〜＃〜] memory [〜＃〜]一時テーブルのサイズの制限（max_heap_table_size/_ram）= 256M/7680M = 3.3％-SELECT内の一時テーブルに（一部のSELECTごとに一時テーブルごとに）MEMORYテーブルが必要な場合に割り当てるには、RAMの割合）。高すぎると、スワッピング（max_heap_table_sizeはユーザーがMEMORYテーブルも制限します。）-両方を減らして、たとえば、RAMの1％にします。
（local_infile）= ON-local_infile = ONは潜在的なセキュリティ問題です
（Created_tmp_disk_tables）= 45,149/7754 = 5.8 /秒-複雑なSELECTの一部としてdisk "temp"テーブルを作成する頻度（Created_tmp_disk_tables /（Created_tmp_disk_tables + Created_tmp_tables））= 45,149 /（45149 + 113444）= 28.5％-ディスクに流出した一時テーブルの割合-一時テーブルがMyISAMの代わりにMEMORYを使用できるようにするためのルールを確認します。 MyISAMを回避するために、スキーマまたはクエリに小さな変更を加えることができる場合があります。インデックスの改善とクエリの再構成も役立ちます。
-tmp_table_sizeを減らして、RAMが不足しないようにします。おそらく64M以下です。
（Select_scan）= 50,953/7754 = 6.6 /秒-全表スキャン（Select_scan/Com_select）= 50,953/700098 = 7.3％-全表スキャンを実行する選択の割合。 （ストアドルーチンにだまされる可能性があります。）-インデックスを追加するか、クエリを最適化します（小さなテーブルでない限り）。
（binlog_format）= MIXED-STATEMENT/ROW/MIXED。 ROWが推奨されます。デフォルトになる場合があります。
（expire_logs_days）= 0-binlogを自動的にパージするまでの時間（この日数が経過した後）-大きすぎる（またはゼロ）=ディスク容量を消費する。小さすぎる=ネットワーク/マシンのクラッシュに迅速に対応する必要がある.
（slow_query_log）= OFF-遅いクエリをログに記録するかどうか。 （5.1.12）（long_query_time）= 10.000000 = 10-「遅い」クエリを定義するためのカットオフ（秒）。 -提案ONおよび2
（Com_flush）= 12/HR（Com_purge）= 12/HR-多くのFLUSHeとPURGEを何が行っていますか？これらはどちらもほとんど使用されないコマンドです。
クエリキャッシュが半分オフになります。 query_cache_type = OFFとquery_cache_size = 0の両方を設定する必要があります。 （噂によると）QCコードに「バグ」があり、両方の設定をオフにしない限り、一部のコードはオンのままになります。
