リポ登録なしでnginxをインストールすると、default.confが作成されない

Hoi Doei

以下、掲題の件につき、私のデスクトップ環境（VirtualboxにCentOSとUbuntuをインストール済み）で行ったものです。もしかしたら、環境によっては同じにはならないかもしれません。

１．CentOS（CentOS7.7、7.9でVirtualboxでスナップショットを使用して検証）

２．Ubuntu（20.04でVirtualboxでsources.list削除&apt-get –purge removeで初期化し、インストールし直して検証)

３．結論

CentOSでは、下記のようにインストールすると、/etc/nginx/conf.d/default.confが作成される。


yum install epel-release -y
vi /etc/yum.repos.d/nginx.repo　　　
----編集開始----
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/mainline/centos/7/$basearch/
gpgcheck=0
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
----編集終了----
yum -y install nginx
```

Ubuntuでは、下記コマンドでインストールすると、/etc/nginx/conf.d/default.confが作成される。


wget https://nginx.org/keys/nginx_signing.key
sudo apt-key add nginx_signing.key
sudo vi /etc/apt/sources.list
----以下2行を末尾に追加
----
deb http://nginx.org/packages/ubuntu/ bionic nginx
deb-src http://nginx.org/packages/ubuntu/ bionic nginx
----追加終了----
apt install nginx
