无法访问Solr服务器（Fedora httpd，solr 5，Drupal 8）

Question

After installing solr 5 with the install_solr_service.sh script, I enabled the service

systemctl enable solr

But Drupal 8 search_api_solr module is complaining that solr server could not be reached although I can open solr backend interface on localhost in my web browser.

Answer 1

SELinux阻止了8983端口上的服务通信，这里是解决方法：

semanage port -a -t http_port_t -p tcp 8983
