AWS EC2でSSL対応のTomcat7を443番ポートで動かす

Amazon Linux AMIで，SSL対応のTomcat7を443番ポートで動くよう設定したときの備忘録．

インストール

$ sudo yum install tomcat7

自己署名の鍵を作成．CN値はPublic DNSなどを設定する．

$ sudo keytool -genkey -alias tomcat -keyalg RSA
$ sudo mv /root/.keystore /etc/tomcat7/keystore

設定ファイルを修正．

$ sudo cp -p /etc/tomcat7/server.xml /etc/tomcat7/server.xml.orig
$ sudo vim /etc/tomcat7/server.xml

$ diff -u /etc/tomcat7/server.xml.orig /etc/tomcat7/server.xml

サービス起動

$ sudo service tomcat7 start

簡単な動作確認．

$ curl -X GET https://localhost:8443
curl: (60) Issuer certificate is invalid.
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

システム起動時にTomcatも起動

$ sudo chkconfig tomcat7 on

443番ポートへの通信を8443番ポートへ転送するように設定し，設定ファイルを出力．

$ sudo /sbin/iptables -t nat -A PREROUTING -j REDIRECT -p tcp --destination-port 443 --to-ports 8443
$ sudo service iptables save
