Oracle Autonomous Linuxでwordpressサーバを建ててみた


Oracle CloudのTOKYOリージョンでFree tierのOracle Autonomouse Linux 7.8環境の作成が出来た。

できたんだけど、標準で提供されているレポジトリの範囲が狭く、通常のOracle Linux 7.8の標準レポジトリにも足りていない。

このため、wordpressサーバを建ててみるかと思っても、要求されるphpおよびmariadbのバージョンに足りていない。

Oracle Autonomous Linuxとしてのマニュアルがなく、ソフトウェア追加に関する制限事項等が分からないが、他に使い道も無いので、通常のOracle Linux 7.8で設定されているレポジトリとかを追加してみることにした。

php 7.4追加編

いろいろある中、Oracle自身が出していてOracle Linux 7.8でも追加できるPHP Packages for Oracle Linuxかな、と追加してみる。

Oracle Linuxのレポジトリ設定の中からphp7.4部分を抜き出して /etc/yum.repos.d/oracle-php.repo というファイルを作成。

[ol7_developer_php74]
name=Oracle Linux $releasever PHP 7.4 Packages for Development and test ($basearch)
baseurl=https://yum$ociregion.oracle.com/repo/OracleLinux/OL7/developer/php74/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1

そしてphpをインストール

# yum install php

MariaDB追加編

SQLサーバのmariadb-serverパッケージについては、MariaDB Foundationからmariadb 10.5を導入することにした。

「/etc/yum.repos.d/mariadb.repo」というファイルを作り、以下の内容を入力

# MariaDB 10.5 RedHat repository list - created 2020-06-26 04:54 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.5/rhel7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
#

そののち「yum install MariaDB-server MariaDB-client」を実行してmariadb-serverをインストール

# yum install MariaDB-server MariaDB-client
<中略>
---> Package perl-Compress-Raw-Zlib.x86_64 1:2.061-4.el7 will be installed
--> Finished Dependency Resolution

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
#

どうやら「pcre2」と「socat」がOracle Autonomous Linuxでは提供されていないパッケージであるようだ。(標準のOralce Linux 7.8ではol7_latestレポジトリに含まれている)

先ほど指定したmariadbレポジトリはRedHat Enterprise Linux 7用だったので、CentOS7用(baseurl=http://yum.mariadb.org/10.5/centos7-amd64 )に変更しても状況は変わらず。

では、とバージョンを10.4に下げてみると成功。成功時のmariadb.repoは以下

MariaDB設定編

まず、現在のMariaDBサーバの自動起動設定を確認。

# systemctl list-unit-files|grep mariadb
mariadb.service                               disabled
mariadb@.service                              disabled
#

自動起動しない設定になっているので、自動起動するように変更する

# systemctl enable mariadb.service
Created symlink from /etc/systemd/system/mysql.service to /usr/lib/systemd/system/mariadb.service.
Created symlink from /etc/systemd/system/mysqld.service to /usr/lib/systemd/system/mariadb.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
#

続いてMariaDBの起動状況を確認

# systemctl status mariadb
● mariadb.service - MariaDB 10.4.13 database server
   Loaded: loaded (/usr/lib/systemd/system/mariadb.service; enabled; vendor preset: disabled)

           https://mariadb.com/kb/en/library/systemd/
#

「Active: inactive (dead)」なので起動していないので「systemctl start mariadb」で起動する。

Webサーバ設定

nginxへの切り替え

最初はApacheを使おうとしたのですが、Mozilla SSL Configuration Generators推奨設定を行うにはmod_rewriteやmod_headersが含まれていませんでした。

Apache関連の追加レポジトリを探すよりはWebサーバをnginxに切り替えてnginx公式レポジトリを使った方が良いのでは?ということで「nginx: Linux packages」を元に追加

/etc/yum.repos.d/nginx.repo に下記を記載

[nginx-stable]

ブラウザからアクセスできるか確認

Let’s encryptを利用したSSLアクセス有効化

Oracle Autonomous Linuxにはcertbotもdehydratedもありません。

certbotはpython環境を使い大がかりになってしまうので、dehydratedの方を使用します。

githubのdehydratedからダウンロードします。

# wget https://github.com/dehydrated-io/dehydrated/archive/master.tar.gz
# tar xfz master.tar.gz
# ls -l
total 88
drwxrwxr-x. 4 root root  4096 Apr 29 04:36 dehydrated-master
-rw-r--r--. 1 root root 82951 Jun 26 16:32 master.tar.gz 
# 

dehydrated と config を配置します。

# cp dehydrated-master/dehydrated /usr/local/sbin/
# ls -l /usr/local/sbin/dehydrated
-rwxr-xr-x. 1 root root 69787 Jun 26 16:35 /usr/local/sbin/dehydrated
# mkdir /usr/local/etc/dehydrated
# cp dehydrated-master/docs/examples/config /usr/local/etc/dehydrated
# ls -l /usr/local/etc/dehydrated
total 8
-rw-r--r--. 1 root root 4656 Jun 26 16:36 config
#

/usr/local/etc/dehydrated/domains.txt にSSL証明書を取得するドメイン名を列挙します。

dehydratedがSSL証明書取得の際に使用する作業用Web公開ディレクトリ /var/www/dehydrated に関する設定をnginxに行います。

まず、ディレクトリを作成

# mkdir /var/www/dehydrated
#

次にnginx側の設定 を /etc/nginx/conf.d/default.conf のlisten 80に関するlocaltionに下記を追加。

location ^~ /.well-known/acme-challenge {
        alias /var/www/dehydrated;
        break;
}

そして、nginx再起動

# systemctl restart nginx
#

準備が出来たのでdehydratedで登録を開始。

# dehydrated --register
# INFO: Using main config file /usr/local/etc/dehydrated/config

To use dehydrated with this certificate authority you have to agree to their terms of service which you can find here: https://letsencrypt.org/documents/LE-SA-v1.2-November-15-2017.pdf

To accept these terms of service run `/usr/local/sbin/dehydrated --register --accept-terms`.

SSL証明書は /usr/local/etc/dehydrated/certs/FQDN名ディレクトリ に作成されます。

nginx側の設定はMozilla SSL Configuration Generator を元に /etc/nginx/conf.d/default.conf を書き換えます。

Mozilla的にはffdhe2048.txtの配置を推奨するようなので、下記でダウンロードして配置します。

# curl https://ssl-config.mozilla.org/ffdhe2048.txt > /usr/local/etc/dehydrated/certs/dhparam
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

#

そして、nginxを再起動します。

# systemctl restart nginx
#

ブラウザからhttpアクセスすると、httpsアクセスに変換された上で404 Not Found表示となることを確認します。

Let’s のSSL証明書は定期的に更新処理を実行する必要があります。

/etc/cron.d/dehydrated に下記の内容のファイルを作成します。(EPEL収録のdehydratedパッケージの内容を参考にした)

WordPress設定

WordPress用のnginx設定は「nginx WordPress recipe」 を参考に作成した。元はphp-cgiを使用していたが、php-cgiパッケージはないためphp-fpm使用に切り替えている。

phpにMySQLアクセス用パッケージを入れていなかった・・・

またphpの日本語処理に必要なやつもなかったので「yum install php-mysql php-mbstring」でインストールして、php-fpmを再起動

# yum install php-mysql php-mbstring

成功

wp-config.php については手動で/var/www/html/wordpress/wp-config.php に作成する必要があったが、それ以外は問題無く実行された。

また、Wordpress上のプラグインインストールや更新についても特に問題なく実行できた。


2020/06/30追記

WordPressのAMPプラグインを動かそうとしたら「dom」が有効にできない、と言われた。

これはphp-xmlに含まれるので「yum install php-xml」で追加したあと「systemctl restart php-fpm.service」を実行した。
