問題

The Base URL Health Check verifies if Jira is able to access its own Base URL. Starting in Jira 7.1, gadgets charts are generated using Javascript in the browser rather than server-side with Java. This had significant performance improvements as the server was offloading processing to the browsers and resulted in less CPU usage. Part of the change modified the way Jira previously operated, and now it is required that the server can connect to itself.

Gadget titles showing as __MSG_gadget.xxxxxxx, __MSG_gadget.activity., __MSG_gadget.filter, _MSG_gadget.project.title_  and so on as per the example below:

Jira is able to access itself through the configured Base URL

Your dashboard gadgets should be generated and loaded correctly.

Jira is not able to access itself through the configured Base URL. This is necessary so that dashboard gadgets can be generated successfully. Please verify the current Base URL and if necessary, review your network configurations to resolve the problem

Your dashboard gadgets may not be loading properly. Please follow the diagnosis and resolution steps below to resolve the problem.

診断

環境

  • iptables80 から 8080、443 から 8443 にパケットを転送するよう設定されている
  • From the Jira server itself, try curl -v <baseurl> to verify if JIRA is able to communicate with itself.
  • Run SSLPoke from the Jira server itself and see if it returns successfully.
  • Additionally, run the httpclienttest from the Jira server itself to confirm if the SSL configuration is okay.
  • There are application links configured on the instance but they seem to be having issues.
  • As the symptoms for both environments are different, diagnosis and resolution steps are segregated into multiple sections below.

When accessing the Dashboard, the gadgets serve a response that is processed by the client (ie the browser) to generate gadgets. Whilst this happens, the server also connects to itself to provide the gadget's translated strings. Jira uses the URL the instance is connected to, so the JIRA instance needs to be able to access itself.


プロキシを使用しない場合

  1. The user sends a request towards Jira on loading the Dashboard
  2. Jira will perform a call towards itself, through the gadget URL.
  3. Jira reply with the completed page + gadget's translated strings
プロキシを使用する場合


1. User sends request towards Jira on loading the Dashboard
2. Proxy forwarded this request to Jira
3. Jira will perform a call back to itself through the gadget URL to get the gadget's title. Performing request to Proxy
4. Proxy forwarded this request back to Jira itself to provide the gadget's translated strings
5. Jira replies gadget's translated strings to proxy
6. Proxy forwarded this accordingly to Jira
7. Jira replies with the completed page to proxy
8. Proxy forwarded this accordingly to use


この処理が行えない場合、エラーが発生します。要因として次のものが考えられます。

  • Basic or certificate-based auth on a proxy layer that Jira is behind
  • ドメイン名の解決不可
  • Jira is served on an IP that's in a separate restricted subnet to the server Jira is running on
  • Jira が自己署名証明書で提供されているが、これが自身の証明書ストアに存在しない
  • There are more than 3 redirects between the entry point and the final Jira server (this is tested in the base URL check and also configured in our gadgets).

The recommended best practice is to have Jira served on one domain name only. This can have different IPs (for example internal and external) configured by different DNS, however will only resolve to one domain. For example https://jira.atlassian.com has an external IP of 131.103.28.11 (mapped to by external DNS) and an internal IP of 192.168.1.2 (mapped with an internal DNS). It has one certificate for that FQDN, and all users access it on that domain only.

 この問題には、環境固有の原因がある場合もあります。詳細については以降を参照してください。


ソリューション

Cause 1: Jira applications with SSL Configured

atlassian-jira.log ファイルに次の情報が表示されます。

2016-02-26 14:22:28,843 http-bio-8443-exec-11 ERROR admin 862x395x1 m32d6k xx.xx.xx.xx /secure/MyJiraHome.jspa [c.a.g.r.internal.http.HttpClientFetcher] Unable to retrieve response
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
	at sun.security.ssl.Alerts.getSSLException(Alerts.java:192)Cause

ソリューション

  1. Verify that the Root and Intermediate CA certificates were added to the keystore when SSL was configured.
  2. Follow our instructions in our Unable to connect to SSL services due to "PKIX Path Building Failed" error knowledge base article for additional details to resolve the problem.
  3. Additionally, verify the configuration with httpclienttest as described in the readme of that repository, to gather more detail.


Cause 2: Jira Applications with port forwarding configured

iptables などでポート フォワードを使用している環境に適用されます。

原因

If port forwarding has been configured to forward packets from 80 to 8080 and/or 443 to 8443, you may see gadget titles be broken and show as __MSG_gadget.xxxxxxx.  This can happen if the rules are configured only to forward packets from external sources.  

解決状況:

You need to create a rule both for packets coming from external IP sources AND for local packets.

For example, in iptables, it should look like this:

iptables -t nat -I OUTPUT -p tcp -o lo --dport 80 -j REDIRECT --to-ports 8080

For firewalld:

firewall-cmd --permanent --add-masquerade
firewall-cmd --permanent --add-forward-port=port=80:proto=tcp:toport=8080

In Windows, we can use the netsh command, like this:

netsh interface portproxy add v4tov4 listenport=80 connectport=8080


Cause 3: Jira applications with a broken Proxy configuration

Applies to environments configured to use a Web Proxy. This can be determined by checking the "JVM Arguments" in the System Information screen for existing proxy configurations.

原因

Jira is unable to communicate with itself due to a Web Proxy not being able to correctly resolve the Jira Server.

ソリューション

Add the JIRA Server's hostname/ to the -Dhttp.nonProxyHosts and -Dhttps.nonProxyHosts arguments as in Configure an outbound proxy for use in Jira server.

Make sure that the same domain is not being mentioned twice in an argument, e.g. - Dhttps .nonProxyHosts = jira|confluence|jira


Cause 4: Jira configured with Apache in front with BasicAuth password restriction

原因

Jira is unable to communicate with itself due to a Web Proxy requiring authentication.

ソリューション

パスワードなしのアクセスを許可するようにサーバー自身の IP を追加します。

Order Allow,Deny
Allow from <hostname>
Satisfy Any

ソリューション 2

If using Shibbolethauthentication ,

  1. leave the /rest URLs outside theshibbolethauthentication.
  2. /rest URL は Shibboleth の保護対象外である必要があります。
  3. 例:
<LocationMatch "^(/rest)/[^/]+">
AuthType None
Require all granted
</LocationMatch>

<LocationMatch "/">
AuthType Shibboleth
ShibRequireSession On
require valid-user
ShibUseEnvironment On
Order allow,deny
Allow from all
</LocationMatch>
