keterってどうよ
yesodのproduction環境へのデプロイってどうやってやるのかなと思いつつ調べていたらketerなるものを見つけたのでやってみました。
keterを使ってyesodのデプロイとdaemonizeしてみる
keterはyesodのデプロイとdaemonizeまでやってくれる
keterをインストール
とりあえずインストール
karky7 ~ # emerge -pv dev-haskell/keter
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild N ~] dev-haskell/keter-1.4.3.1:0/1.4.3.1::haskell USE="doc hoogle hscolour profile -system-filepath {-test}" 0 KiB

* IMPORTANT: 42 news items need reading for repository 'gentoo'.
* Use eselect news read to view new items.
karky7 ~ #
そして設定
karky7 ~ # cp /etc/keter/keter.yaml.systemd /etc/keter/keter.yaml karky7 ~ # mkdir -p /web/incoming
keterのIPとポートを決める

yesodプロジェクトを作成
どこでもいいので作る
karky7 ~ # yesod init
Welcome to the Yesod scaffolder.
I'm going to be creating a skeleton Yesod project for you.
What do you want to call your project? We'll use this for the cabal name.
Project name: yapp
Yesod uses Persistent for its (you guessed it) persistence layer.
This tool will build in either SQLite or PostgreSQL or MongoDB support for you.
We recommend starting with SQLite: it has no dependencies.
s = sqlite
p = postgresql
pf = postgresql + Fay (experimental)
mongo = mongodb
mysql = MySQL
simple = no database, no auth
mini = bare bones, the "Hello World" of multi-file Yesod apps
(Note: not configured to work with yesod devel)
url = Let me specify URL containing a site (advanced)
So, what'll it be? simple
That's it! I'm creating your files now...

---------------------------------------
The foundation for your web application has been built.
There are a lot of resources to help you use Yesod.
Start with the book: http://www.yesodweb.com/book
Take part in the community: http://yesodweb.com/page/community
It's highly recommended to follow the quick start guide for
installing Yesod: http://www.yesodweb.com/page/quickstart
If your system is already configured correctly, please run:
cd yapp && stack build && stack exec -- yesod devel

# Use the following to automatically copy your bundle upon creation via `yesod
# keter`. Uses `scp` internally, so you can set it to a remote destination
# copy-to: user@host:/opt/keter/incoming/
# You can pass arguments to `scp` used above. This example limits bandwidth to
# 1024 Kbit/s and uses port 2222 instead of the default 22
# copy-to-args:
# - \"-l 1024\"
# - \"-P 2222\"
# If you would like to have Keter automatically create a PostgreSQL database
# and set appropriate environment variables for it to be discovered, uncomment
# the following line.
# plugins:
# postgres: true

keter起動
うまくいけば、起動するはず
karky7 ~ # systemctl start keter karky7 ~ # ps -ef | grep keter root 10381 1 0 22:00 ? 00:00:00 /usr/bin/keter /etc/keter/keter.yaml root 10400 10381 0 22:00 ? 00:00:00 /usr/bin/keter /etc/keter/keter.yaml karky7 ~ # karky7 ~ # netstat -l Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 *:43124 *:* LISTEN tcp 0 0 *:ssh *:* LISTEN tcp 0 0 localhost:3000 *:* LISTEN ...
nginxを設定、起動する
serverセクションを追加する、「proxy_set_header Host $host;」が重要、これないとうまく動かない
server {
listen 80;
server_name kamegashira.jp;
location / {
proxy_pass http://127.0.0.1:3000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Fowarded-For $proxy_add_x_forwarded_for;
}
access_log /var/log/nginx/localhost.access_log main;
error_log /var/log/nginx/localhost.error_log info;
}
そしてnginx起動
karky7 ~ # systemctl start nginxブラウザで「http://www.kamegashira.jp/」にアクセスしてみる
是非みなさんhaskellでyesodなクリスマスを彼女と過ごしてください!
