OpenShiftってSSHでログインもできるんだ

Remote Connection (SSH)を見てみたら普通にSSHでGearにログインできるみたいなのでやってみた。

$ rhc ssh myphpapp RSA 1024 bit CA certificates are loaded due to old openssl compatibility Connecting to 56b61d5c89f5cf92a000003f@myphpapp-xxxxxx.rhcloud.com ...       *********************************************************************       You are accessing a service that is for use only by authorized users.     If you do not have authorization, discontinue use at once.     Any use of the services is subject to the applicable terms of the     agreement which can be found at:     https://www.openshift.com/legal       *********************************************************************       Welcome to OpenShift shell       This shell will assist you in managing OpenShift applications.       !!! IMPORTANT !!! IMPORTANT !!! IMPORTANT !!!     Shell access is quite powerful and it is possible for you to     accidentally damage your application.  Proceed with care!     If worse comes to worst, destroy your application with "rhc app delete"     and recreate it     !!! IMPORTANT !!! IMPORTANT !!! IMPORTANT !!!       Type "help" for more info.     [myphpapp-xxxxxx.rhcloud.com 56b61d5c89f5cf92a000003f]\>

でも使えるコマンドは限られてるみたい。

\> help Help menu: The following commands are available to help control your openshift application and environment.   gear            control your application (start, stop, restart, etc)                 or deps with --cart      (gear start --cart mysql-5.1) tail_all        tail all log files export          list available environment variables rm              remove files / directories ls              list files / directories ps              list running applications kill            kill running applications mysql           interactive MySQL shell mongo           interactive MongoDB shell psql            interactive PostgreSQL shell quota           list disk usage   Deprecated: ctl_app         control your application (start, stop, restart, etc) ctl_all         control application and deps like mysql in one command

簡単なの使ってみよう。

[myphpapp-xxxxxx.rhcloud.com 56b61d5c89f5cf92a000003f]\> ls app-deployments  app-root  git php

ファイルやディレクトリは見える。

動いているプロセスも見えるみたい。

[myphpapp-xxxxxx.rhcloud.com 56b61d5c89f5cf92a000003f]\> cat /etc/redhat-release Red Hat Enterprise Linux Server release 6.7 (Santiago)

OSはRedHat EnterPrise 6.7か。

[myphpapp-xxxxxx.rhcloud.com 56b61d5c89f5cf92a000003f]\> env MANPATH=/opt/rh/php54/root/usr/share/man: OPENSHIFT_SECRET_TOKEN=wD_1nmlzQ0FN8WHQ_Xs5hsUAiermXB5i7GVLGFP1N7w6_wGfnAT9PZNgwecEUpOGAJIp1ER8Ao-lGBwx8dU_8Q9fqn-R482B6JF9aySaXIXp9ScZZ8xY0Q_MeqZPzFJ1 OPENSHIFT_PHP_IDENT=redhat:php:5.4:0.0.28 OPENSHIFT_GEAR_MEMORY_MB=512 SELINUX_ROLE_REQUESTED= OPENSHIFT_DEPLO ： ：

helpには書いてないけどenvで環境変数も見えるみたい。

Herokuよりも無料枠が良さげなOpenShiftでPHPをデプロイする

Herokuよりも無料枠が良さげなOpenShiftをつかってみるでアカウントとGearを作ってPHP Cartridgeを用意した。

今度はGetting Started with PHPを辿ってブラウザで確認できるまでやってみる。

アカウントは作ったけどrhcコマンドはインストールしていないのでリンク先からインストールする。僕の場合はMac版をインストール。

$ sudo gem install rhc Password: Fetching: net-ssh-2.9.2.gem (100%) Successfully installed net-ssh-2.9.2 Fetching: net-scp-1.2.1.gem (100%) Successfully installed net-scp-1.2.1 Fetching: net-ssh-gateway-1.2.0.gem (100%) Successfully installed net-ssh-gateway-1.2.0 Fetching: net-ssh-multi-1.2.1.gem (100%) Successfully installed net-ssh-multi-1.2.1 Fetching: archive-tar-minitar-0.5.2.gem (100%) Successfully installed archive-tar-minitar-0.5.2 Fetching: highline-1.6.21.gem (100%) Successfully installed highline-1.6.21 Fetching: commander-4.2.1.gem (100%) Successfully installed commander-4.2.1 Fetching: httpclient-2.7.1.gem (100%) Successfully installed httpclient-2.7.1 Fetching: open4-1.3.4.gem (100%) Successfully installed open4-1.3.4 Fetching: rhc-1.38.4.gem (100%) ===========================================================================   If this is your first time installing the RHC tools, please run 'rhc setup'   =========================================================================== Successfully installed rhc-1.38.4 Parsing documentation for net-ssh-2.9.2 Installing ri documentation for net-ssh-2.9.2 Parsing documentation for net-scp-1.2.1 Installing ri documentation for net-scp-1.2.1 Parsing documentation for net-ssh-gateway-1.2.0 Installing ri documentation for net-ssh-gateway-1.2.0 Parsing documentation for net-ssh-multi-1.2.1 Installing ri documentation for net-ssh-multi-1.2.1 Parsing documentation for archive-tar-minitar-0.5.2 Installing ri documentation for archive-tar-minitar-0.5.2 Parsing documentation for highline-1.6.21 Installing ri documentation for highline-1.6.21 Parsing documentation for commander-4.2.1 Installing ri documentation for commander-4.2.1 Parsing documentation for httpclient-2.7.1 Installing ri documentation for httpclient-2.7.1 ^@Parsing documentation for open4-1.3.4 Installing ri documentation for open4-1.3.4 Parsing documentation for rhc-1.38.4 Installing ri documentation for rhc-1.38.4 10 gems installed

初めてのインストールだったら'rhc setup'を実行しろと書いてあるので素直にやってみる。

$ rhc setup OpenShift Client Tools (RHC) Setup Wizard   This wizard will help you upload your SSH keys, set your application namespace, and check that other programs like Git are properly installed.   If you have your own OpenShift server, you can specify it now. Just hit enter to use the server for OpenShift Online: openshift.redhat.com. Enter the server hostname: |openshift.redhat.com|

サブドメインでそのまま使っているのでEnter。

You can add more servers later using 'rhc server'. RSA 1024 bit CA certificates are loaded due to old openssl compatibility   Login to openshift.redhat.com: xxxxxxxx@hogehoge.com Password: *********

素直に作成したアカウントのメールアドレスとパスワードを入力。

OpenShift can create and store a token on disk which allows to you to access the server without using your password. The key is stored in your home directory and should be kept secret.  You can delete the key at any time by running 'rhc logout'. Generate a token now? (yes|no) yes

鍵を作っておくかと聞かれるので作っておく。

We will generate a pair of keys for you.       Created: /Users/xxxxxxx/.ssh/id_rsa.pub   Your public SSH key must be uploaded to the OpenShift server to access code.  Upload now? (yes|no) yes

鍵を作った後、今、サーバにアップロードをするか聞かれるのでyes

とりあえずrhcコマンドの準備は整った。

Once that is completed, open a terminal on a local machine and change into the directory where you would like the OpenShift application source code to be located. At the command prompt, enter the following command to create a PHP application:

$ rhc app create myphpapp php-5.4

アプリケーションを作成しよう。
今回は~/Documentフォルダの下に"OpenShift Project"を作成した上で、そこに移動しコマンドを入力する。

$ rhc app create myphpapp php-5.4 RSA 1024 bit CA certificates are loaded due to old openssl compatibility Application Options ------------------- Domain:     xxxxxxxxxx Cartridges: php-5.4 Gear Size:  default Scaling:    no   Creating application 'myphpapp' ... done     Waiting for your DNS name to be available ... done   Cloning into 'myphpapp'...

Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'myphpapp-xxxxxxxxxx.rhcloud.com,52.91.58.98' (RSA) to the list of known hosts.   Your application 'myphpapp' is now available.     URL:        http://myphpapp-xxxxxxxxxx.rhcloud.com/   SSH to:     56b61d5c89f5cf92a000003f@myphpapp-xxxxxxxxxx.rhcloud.com   Git remote: ssh://56b61d5c89f5cf92a000003f@myphpapp-xxxxxxxxxx.rhcloud.com/~/git/myphpapp.git/   Cloned to:  /Users/xxxxxx/Documents/OpenShift Project/myphpapp   Run 'rhc show-app myphpapp' for more details about your app.

これでリモートリポジトリとアプリが作成された。ローカルの中にもmyphpappというディレクトリができているので、中を見てみよう。

$ cd myphpapp/ $ ls -aFCl total 80 drwxr-xr-x   5 xxxxxx  staff    170  2  7 01:22 ./ drwxr-xr-x   3 xxxxxx  staff    102  2  7 01:22 ../ drwxr-xr-x  13 xxxxxx  staff    442  2  7 01:22 .git/ drwxr-xr-x   7 xxxxxx  staff    238  2  7 01:22 .openshift/ -rw-r--r--   1 xxxxxx  staff  39585  2  7 01:22 index.php

ここで上で表示されたURLにブラウザからアクセスしてみる。

phpinfo()を書いたphpファイルを作成してみる。test.phpとかでいいか。

test.php

<?php phpinfo();

gitでローカルリポジトリにコミットする。

$ git add --all $ git commit -m "add test.php" [master 6da6e33] add test.php  Committer: xxxxxx xxxxxx@xxxxxx-no-MacBook-Pro.local> Your name and email address were configured automatically based on your username and hostname.

その後、サイトにpushする。

$ git push warning: push.default is unset; its implicit value has changed in Git 2.0 from 'matching' to 'simple'. To squelch this message and maintain the traditional behavior, use:     git config --global push.default matching   To squelch this message and adopt the new behavior now, use:     git config --global push.default simple   When push.default is set to 'matching', git will push local branches to the remote branches that already exist with the same name.   Since Git 2.0, Git defaults to the more conservative 'simple' behavior, which only pushes the current branch to the corresponding remote branch that 'git pull' uses to update the current branch.   See 'git help config' and search for 'push.default' for further information.

これでブラウザでアクセスしてみるときちんと反映された。
