Dan commented on SOLR-7562: --------------------------- On debian/ubuntu, enabling this will make the init-script hang for a while, then fail without explanation and Solr never gets started. It was only when finding this bugreport, that i found out i had to add the hostname in /etc/hosts, which isnt there by default on many cloud hosts, including amazon. > ENABLE_REMOTE_JMX_OPTS=true without Host Name specified. > --------------------------------------------------------- > > Key: SOLR-7562 > URL: https://issues.apache.org/jira/browse/SOLR-7562 > Project: Solr > Issue Type: Improvement > Components: JMX, scripts and tools > Affects Versions: 5.1 > Environment: Centos 6.6 > Reporter: Shreejay > Priority: Minor > Labels: improvement, suggestion > > This is not a big issue, but might be confusing for new users if they do not > have the hostname set in their servers. > Steps taken to reproduce the issue: > 1) Downloaded solr tar file to /opt folder. > 2)Extract install_solr_service.sh file > {quote} tar xzf solr-5.1.0.tgz solr-5.1.0/bin/install_solr_service.sh > --strip-components=2{quote} > 3) run install_solr_service.sh file. > {quote} > sudo bash ./install_solr_service.sh solr-5.1.0.tgz > {quote} > The above step starts solr with default options. > 4) Stop solr - {quote}service solr stop{quote} > 5) Change the JMX options in include folder at /var/solr/solr.in.sh > {quote} > ENABLE_REMOTE_JMX_OPTS="true" > {quote} > 6) Start solr again > {quote} > service solr start > {quote} > if the host name is not specified in /etc/hosts file, following message is > displayed > {quote} > tail: cannot open `/var/solr/logs/solr' for reading: No such file or directory > tail: no files remaining > {quote} > solr-8983-console.log file in /var/solr/logs shows the following output > {quote} > Error: Exception thrown by the agent : java.net.MalformedURLException: Local > host name unknown: java.net.UnknownHostException: SERVERNAME: SERVERNAME: > unknown error > {quote} > The error occurs if the /etc/hosts file does not have an entry for > SERVERNAME. > Setting SOLR_HOST=SERVERNAME in solr.in.sh also does not help. > Suggestion: > May be add a message info message when ENABLE_REMOTE_JMX_OPTS=true. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
