24. Mastodonサーバ構築 [さくらのVPS/CentOS7]

・Mastodon のインストール

Mastodon は サブディレクトリ環境では動作しないため、VirtualHostで対応する

#-- 変数に必要な値を代入
VHOST=mstdn.masdon.life
DOMAIN=masdon.life
#-- admin@masdon.life のパスワード
PASSWORD=********
IPV4=$(ip addr show eth0 | awk '/inet /{print $2}' | awk -F\/ '{print $1}' | head -1)
IPV6=$(ip addr show eth0 | awk '/inet6 /&&/global/{print $2}' | awk -F\/ '{print $1}')

#-- 正引きを追加
cat <<_EOL_>> /etc/nsd/zone/${DOMAIN}.zone
mstdn                   IN      A       ${IPV4}

#-- シリアル更新
