CentOS7 で Minecraft1.16.5 の spigot サーバーを立てる方法
Spigot 実行ユーザーを作成
adduser spigotadmin passwd spigotadmin
Buildtoools のダウンロード
インストールディレクトリの作成
mkdir /opt/spigot
所有者の変更
ディレクトリの所有者を「spigotadmin」ユーザーに変更。
chown spigotadmin:spigotadmin /opt/spigot
所有者が変更されていることを確認。
drwxr-xr-x 2 spigotadmin spigotadmin 6 1月 23 11:14 spigot
Buildtoools のダウンロード
「su」コマンドで「spigot」実行ユーザーへ変更して作業を行う。
su - spigotadmin
「spigot」インストールディレクトリに移動し、そこで Buildtoools をダウンロード。
$ cd /opt/spigot
$ wget https://hub.spigotmc.org/jenkins/job/BuildTools/lastSuccessfulBuild/artifact/target/BuildTools.jar
BuildTools.jar がダウンロードされる。
BuildTools.jar
spigot ビルド
git 設定
git で改行コードを設定しないようにするため行う。
$ git config --global --unset core.autocrlf
spigot ビルド実行
$ java -jar BuildTools.jar
ビルド完了。
Success! Everything completed successfully. Copying final .jar files now. Copying spigot-1.16.5-R0.1-SNAPSHOT.jar to /opt/spigot/./spigot-1.16.5.jar - Saved as ./spigot-1.16.5.jar
以下のようにファイルが生成される。

CentOS7 の RAM ディスクの容量を増やす方法
$ df -h
ファイルシス サイズ 使用 残り 使用% マウント位置 （省略） tmpfs 4.0G 37M 4.0G 1% /mnt/ram （省略）
マウント解除
$ umount /mnt/ram/
マウント解除されたことを確認
$ df -h
サイズを5Gにしてマウント
$ mount -t tmpfs -o size=5120m tmpfs /mnt/ram
マウントされていることを確認
$ df -h （省略） tmpfs 5.0G 0 5.0G 0% /mnt/ram （省略）
再起動後も自動マウントするよう fstab を編集
$ vi /etc/fstab
編集前
tmpfs /mnt/ram tmpfs defaults,size=4096m 0 0
編集後
tmpfs /mnt/ram tmpfs defaults,size=5120m 0 0

【PHP】多次元配列の列のすべての値を合計する方法
以下のような多次元配列があります。
$array10 = array(
array(
"kill" => array(
"zombie" => 10,
"skeleton" => 15
),
"killed" => array(
"zombie" => 5,
"skeleton" => 3
)
),
array(
"kill" => array(
"zombie" => 20,
"skeleton" => 30
),
"killed" => array(
"zombie" => 10,
"skeleton" => 6
)
)
);
killのzombie、killのskeleton及びkilledのzombie、killedのskeletonそれぞれ項目別に合計する方法。
foreach ($array10 as $subArray) {
foreach ($subArray as $key => $values) {
foreach ($values as $id => $value) {
$array11[$key][$id] += $value;
}
}
}
