---------------Apache導入↓↓-------------------------
# ルートに変更
su - root
# apacheインストール
yum -y install httpd
# apache起動
systemctl start httpd
# apacheが動いてるかブラウザで確認
http://127.0.0.1/
---------------PHP導入↓↓-------------------------
# PHPインストール
yum -y install php
# phpファイル作成するため、移動
cd /var/www/html/
/var/www/html/にPHPファイルを3つ作成
api1.php
<?php
// 連想配列用意
$array = [
'tokyo' => [
'品川',
'五反田',
'三軒茶屋',
'四谷'
]
];
// Origin null is not allowed by Access-Control-Allow-Origin.とかのエラー回避の 為、ヘッダー付与
header("Access-Control-Allow-Origin: *");
# echo json_encode($array);
echo json_encode($array,JSON_UNESCAPED_UNICODE);
?>
api2.php
<?php
// 連想配列用意
$array = [
'kanagawa' => [
'横浜',
'相模原',
'湘南',
'鎌倉'
]
];
// Origin null is not allowed by Access-Control-Allow-Origin.とかのエラー回避の 為、ヘッダー付与
header("Access-Control-Allow-Origin: *");
# echo json_encode($array);
echo json_encode($array,JSON_UNESCAPED_UNICODE);
?>
api3.php
?php
// 連想配列用意
$array = [
'saitama' => [
'所沢',
'狭山',
'川口',
'浦和',
'小手指',
'飯能'
]
];
// Origin null is not allowed by Access-Control-Allow-Origin.とかのエラー回避の 為、ヘッダー付与
header("Access-Control-Allow-Origin: *");
# echo json_encode($array);
echo json_encode($array,JSON_UNESCAPED_UNICODE);
?>
PHP実行
# まずはApache再起動
systemctl restart httpd
# ブラウザでアクセス（JSON形式で市の名称がでればOK）

gatling 構築
以下の記事を参考に構築
https://medium.com/eureka-engineering/gatring-stress-test-14ac5efdfcbc
# rootフォルダ移動
su - root
cd /root
# gatlingのライブラリーをダウンロード
curl -O https://repo1.maven.org/maven2/io/gatling/highcharts/gatling-charts-highcharts-bundle/3.3.1/gatling-charts-highcharts-bundle-3.3.1-bundle.zip
# gatlingのライブラリーを解凍
unzip gatling-charts-highcharts-bundle-3.3.1-bundle.zip
# javaがインストールされてるか確認(java8や11がないと動かないらしい)
java -version
# gatlingの実行ソース作成(BasicSimulation.scalaのベースの実行ファイルをコピー)
cd gatling-charts-highcharts-bundle-3.3.1/user-files/simulations/
mkdir api
cp -p computerdatabase/BasicSimulation.scala api/ApiSimulation.scala
上記でコピーした（ApiSimulation.scala）を作成
package api //パッケージ名指定
import io.gatling.core.Predef._
import io.gatling.http.Predef._
import scala.concurrent.duration.
_

.exec(

.get("/api3.php")//作成したPHPファイル指定
)
setUp(scn.inject(atOnceUsers(1)).protocols(httpProtocol)) //1Userで並列実行
}
gatling実行
# gatling実行シェルファイルに移動
cd /root/gatling-charts-highcharts-bundle-3.3.1/bin/
# gatling実行
./gatling.sh
GATLING_HOME is set to /root/gatling-charts-highcharts-bundle-3.3.1
