序文：最近、新しいマシンのバッチをテストする必要があります。主なテスト範囲には、CPUテスト、ディスクIOテスト、スレッドテスト、OLTPテストなどがあり、sysbenchは圧力テストのニーズを満たすことができます。sysbenchのインストールと使用、および圧力テスト結果の解釈を簡単に見てみましょう。
1つは、sysbenchのインストール
sysbenchインストールはあなたが参照することができ、非常に簡単ですgitの、実際には、MySQLの公式サイトがダウンになりますが、古いバージョンすることができ、最新バージョンはsysbench1.1.0あり、ここでは、次のソースコンパイラのインストールについて話しています。
sysbenchをサーバーにアップロードし、解凍してインストールします。
[root@localhost tmp]# unzip sysbench-master.zip
[root@localhost tmp]# cd sysbench-master
[root@localhost sysbench-master]# ./autogen.sh
[root@localhost sysbench-master]# ./configure
[root@localhost sysbench-master]# make -j
[root@localhost sysbench-master]# make install
実際に、README.mdをチェックすると、インストール方法も書き込まれます。
## Build and Install
shell
./autogen.sh
# Add --with-pgsql to build with PostgreSQL support
./configure
make -j
make install
第二に、圧力試験プロセスと圧力試験結果の解釈
1.cpuテスト
[root@localhost storage]# sysbench --test=cpu --cpu-max-prime=2000000 run
WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.
sysbench 1.1.0 (using bundled LuaJIT 2.1.0-beta3)
Running the test with following options:
Number of threads: 1
Initializing random number generator from current time
Prime numbers limit: 2000000
Initializing worker threads...
Threads started!
CPU speed:
events per second: 0.63
Throughput:
events/s (eps): 0.6334
time elapsed: 11.0520s
total number of events: 7
Latency (ms):
min: 1571.86
avg: 1578.84
max: 1620.53
95th percentile: 1618.78
sum: 11051.91
Threads fairness:
events (avg/stddev): 7.0000/0.00
execution time (avg/stddev): 11.0519/0.00
cpuテストは主に素数を追加するためのものです。上の例では、素数ジェネレーターの最大数は2000000と指定されています。サーバーのテスト実行時間は約11.05秒であることがわかります
2.ディスクIOテスト
[root@localhost storage]# sysbench --test=fileio --num-threads=16 --file-total-size=30G --file-test-mode=rndrw prepare
WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.
WARNING: --num-threads is deprecated, use --threads instead

3.圧力測定に関する注意事項
1. OLTPテスト中、データベースが初期化された後、データディレクトリはコールドスタンバイになります。各テストの後に、現在のデータディレクトリが削除され、データディレクトリがコピーされて再起動されます。これにより、各テスト前に同じ環境を維持できます。
2.テストが完了したら、システムレイヤー
シェルでいくつかのクリーンアップ作業を行う必要があります> sync
#refresh dirty data to disk shell> echo 3> / proc / sys / vm / drop_cache #clear cache
shell> swapoff -a && swapon -a release swap
3.パラメータmax_prepared_stmt_countは、ストレステスト中にデフォルトで16382から65536に変更する必要があります。4。SSD
ハードドライブの場合、2つのパラメータinnodb_io_capacityとinnodb_io_capacity_maxもそれに応じて調整する必要があります。
5.テストデータの準備のために、show engine innodb statusを通じて空きバッファを観察し、実稼働環境をシミュレートして、テストデータにバッファプール全体をいっぱいにさせます。ここでは、40Gのinnodb_buffer_pool_sizeを設定しました。テストテーブルの数は10で、各テーブルのデータは2,000万であり、バッファプールをほぼいっぱいにしています。
次の記事では、InnoDBエンジンとTokuDBエンジンのストレステストについて説明します。
