ubuntu18.04 への apache2 新規設定時の手順

Last updated at Posted at 2020-03-20

発行コマンド

環境を作成するたび調べることになるので自分用に

id taro
sudo usermod -aG www-data taro 
id taro 
mkdir ~taro/www-data
sudo chown -R taro.www-data ./www-data/
sudo chmod -R 2770 ./www-data/
sudo find ./www-data/ -type d -exec chmod 770 {} \;
sudo find ./www-data/ -type f -exec chmod 660 {} \;
sudo sed -i".org" -r "s/DocumentRoot.*$/DocumentRoot \/home\/taro\/www-data/" /etc/apache2/sites-enabled/000-default.conf 
sudo vim /etc/apache2/apache2.conf

何をしているか

# グループ事前確認
id taro
sudo usermod -aG www-data taro 
# 変更反映の確認
id taro 
mkdir ~taro/www-data
sudo chown -R taro.www-data ./www-data/
# SGIDを設定する(https://eng-entrance.com/linux-permission-sgid)
sudo chmod -R 2770 ./www-data/
# 既存のディレクトリ、ファイルのパーミッションを置き換える
sudo find ./www-data/ -type d -exec chmod 770 {} \;
sudo find ./www-data/ -type f -exec chmod 660 {} \;
# sedで書き換える(趣味)。バックアップも作成
sudo sed -i".org" -r "s/DocumentRoot.*$/DocumentRoot \/home\/taro\/www-data/" /etc/apache2/sites-enabled/000-default.conf
# directoryに許可設定を入れる(内容については後述)
sudo vim /etc/apache2/apache2.conf

/etc/apache2/apache2.confについては、以下の設定を追加しないといけなかった(詰まった)。

<Directory /home/taro/>
	Options Indexes FollowSymLinks
	AllowOverride None
	Require all granted
</Directory>

知見

~taro/www-data/という形式でディレクトリを指定すると403が出る。
(apache2.confでも、000-default.confでも)

<Directory> 〜 </Directory>で使えるpathは、full pathか正規表現だけみたいですね。

Directory-path is either the full path to a directory, or a wild-card string using Unix shell-style matching. In a wild-card string, ? matches any single character, and * matches any sequences of characters.

Regular expressions can also be used, with the addition of the ~ character. For example:

ref: https://httpd.apache.org/docs/2.4/en/mod/core.html#directory

補足

phpを使うときは

$ sudo apt install libapache2-mod-php7.2
