FedoraのApacheにテスト用のSSL（自己署名証明書）を設定

2008-09-10 Pistolfly コメントする

Chromeに対応するためには、subjectAltNameを設定した自己署名証明書を作成する必要があります。
subjectAltNameが設定されていない証明書はChromeで NET::ERR_CERT_COMMON_NAME_INVALID エラーを参照してください。

あらかじめ用意されているテスト用の仮の鍵と証明書をバックアップする。

# cd /etc/pki/tls
# mv private/localhost.key private/localhost.key.bk
# mv certs/localhost.crt certs/localhost.crt.bk

サーバ鍵を作成する。

# openssl genrsa -out private/test.key 2048

これでパスフレーズなしのサーバ鍵が作成される。

テスト用に自己証明書を作成。

# openssl req -new -x509 -days 3650 -sha256 -key /etc/pki/tls/private/test.key -out /etc/pki/tls/certs/test.crt
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.

Country Name (2 letter code) [GB]:JP
State or Province Name (full name) [Berkshire]:Tokyo
Locality Name (eg, city) [Newbury]:Chiyoda-ku

Organizational Unit Name (eg, section) []:
Common Name (eg, your name or your server's hostname) []:test.pistolfly.jp
Email Address []:webmaster@pistolfly.jp
# apachectl restart

あとは、/etc/httpd/conf.d/ssl.confにバーチャルホストを設定して、
・サーバ鍵と証明書のパス
・その他バーチャルホストの設定
を行う。

MacPortsのApache2にテスト用のSSL（自己署名証明書）を設定

2008-09-08 Pistolfly コメントする

SSLのテスト用に、MacPortsでインストールしたApacheにSSLの設定をした。
conf/httpd.conf

# Secure (SSL/TLS) connections
Include conf/extra/httpd-ssl.conf

秘密鍵と証明書ファイルのパスの設定を確認。（デフォルトのまま使用することにする。）
conf/extra/httpd-ssl.conf

#   Server Certificate:
#   Point SSLCertificateFile at a PEM encoded certificate.  If
#   the certificate is encrypted, then you will be prompted for a
#   pass phrase.  Note that a kill -HUP will prompt again.  Keep
#   in mind that if you have both an RSA and a DSA certificate you
#   can configure both in parallel (to also allow the use of DSA
#   ciphers, etc.)
SSLCertificateFile "/opt/local/apache2/conf/server.crt"
#SSLCertificateFile "/opt/local/apache2/conf/server-dsa.crt"
#   Server Private Key:
#   If the key is not combined with the certificate, use this
#   directive to point at the key file.  Keep in mind that if
#   you've both a RSA and a DSA private key you can configure
#   both in parallel (to also allow the use of DSA ciphers, etc.)
SSLCertificateKeyFile "/opt/local/apache2/conf/server.key"
#SSLCertificateKeyFile "/opt/local/apache2/conf/server-dsa.key"

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/opt/local/lib/mysql5/bin/mysqladmin -u root password 'new-password'
/opt/local/lib/mysql5/bin/mysqladmin -u root -h macbook.local password 'new-password'
Alternatively you can run:
/opt/local/lib/mysql5/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /opt/local ; /opt/local/lib/mysql5/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
Please report any problems with the /opt/local/lib/mysql5/bin/mysqlbug script!
The latest information about MySQL is available on the web at
http://www.mysql.com
Support MySQL by buying support/licenses at http://shop.mysql.com

rootユーザのパスワード設定や匿名アカウント、testデータベースの削除などが以下で実行されるらしい。

$ /opt/local/lib/mysql5/bin/mysql_secure_installation

しかし、実行してみたが、匿名アカウントもtestデータベースも残っていたので、
MySQL :: MySQL 5.1 リファレンスマニュアル :: 2.10.3 最初の MySQL アカウントの確保
を参考に、自分でやる。
mysqlコマンドや、rubyのmysqlアダプタをインストールするときにオプションで指定するmysql-configへのパスを通すため、.bash_profileなどで$PATHに
/opt/local/lib/mysql5/bin
を追加しておく。

# 設定したタイムゾーンでローカルのTimeを作成
t = Time.zone.local(2008, 9, 1, 0, 0)
