Tomcatのインストール

sudo aptitude install -y tomcat7 tomcat7-admin

Tomcatの設定

sudo vi /etc/tomcat7/server.xml

HTTPのConnector設定をコメントアウトし、AJPのConnector設定を有効にする。

GitBucketの配置

$ wget https://github.com/gitbucket/gitbucket/releases/download/3.13/gitbucket.war
$ sudo mv gitbucket.war /var/lib/tomcat7/webapps
$ ls -al /var/lib/tomcat7/webapps
  drwxrwxr-x 4 tomcat7 tomcat7     4096 Apr  7 14:37 .
  drwxr-xr-x 6 root    root        4096 Apr  7 14:24 ..
  drwxr-xr-x 7 tomcat7 tomcat7     4096 Apr  7 14:37 gitbucket
  -rw-r--r-- 1 root    root    39783199 Apr  7 14:37 gitbucket.war
  drwxr-xr-x 3 root    root        4096 Apr  7 14:25 ROOT

ApacheのGitBucket用設定ファイル

$ sudo vi /etc/apache2/sites-available/gitbucket.conf
  <VirtualHost *:443>
    ServerName gitbucket.my-domain:443
    <Location />
      ProxyPass ajp://localhost:8009/
    </Location>
    SSLCertificateFile    /etc/apache2/cert/ssl-cert.pem
    SSLCertificateKeyFile /etc/apache2/cert/ssl-cert.key
  </VirtualHost>
$ sudo a2ensite gitbucket

再起動

$ sudo service tomcat7 restart
$ sudo service apache2 restart

しかし、アクセスしても 404 となる。
/var/log/tomcat7/localhost.2016-04-07.log を見ると、こんなエラーが出ている。

https://github.com/gitbucket/gitbucket/issues/1082 によると、Java8を必要としているがJava8ではない場合に出るエラーのようだ。TomcatがJava8で動いていないっぽい。

JAVA_HOMEの設定

$ sudo vi /etc/default/tomcat7

JAVA_HOME=/usr/lib/jvm/java-8-oracle を追加して再起動。 しかしまだ表示されない。今度はこんなエラー。

/usr/share/tomcat7/.gitbuckeのパーミッション設定

$ sudo chown -R tomcat7:tomcat7 /usr/share/tomcat7

再度再起動したら表示はされたが assets が効いていない。

assets有効化

どうやら assets のパスは固定になっているらしい。今回は VirtualHost でやったため、/gitbucket が存在しないから /gitbucket/assets も当然見えないわけだ。
しかたないので /etc/apache2/sites-available/gitbucket.conf を書き換えた。

    <VirtualHost *:443>
      ServerName gitbucket.my-domain:443
      ProxyReverseHost On
      RewriteEngine On
      ProxyPass /gitbucket ajp://localhost:8009/gitbucket/
      ProxyPassReverse /gitbucket ajp://localhost:8009/gitbucket/
      ProxyPass /gitbucket/assets ! # 静的ファイルはAapacheに処理させる
      Redirect / /gitbucket # ルートにアクセスしても大丈夫なように
      RewriteRule ^/gitbucket/(.*) ajp://localhost:8009/gitbucket/$1 [P,L,QSA]
      SSLCertificateFile    /etc/apache2/cert/ssl-cert.pem
      SSLCertificateKeyFile /etc/apache2/cert/ssl-cert.key
    </VirtualHost>

RewriteRule がないとトップは表示されても、サインインできなかった。
もうちょっとスッキリした設定があるような気がするけど、まあとりあえず。
