在fedora22系统中部署calmari,使用calamari-ctl initialize启动calamari后,访问浏览器,浏览器提示500。查看日志文件/var/log/calmari/httpd_error.log,得到以下内容。

解决方法

原因可能是postgresql自身访问限制、用户权限问题,检查后均被排除。查询资料得知,访问权限被selinux限制了。

  • 第一种方法是设置selinux去掉访问限制
sudo setsebool -P httpd_can_network_connect_db on
  • 第二种方法是关闭selinux

编辑/etc/selinux/config,将参数配为禁用,再重启系统。

SELINUX=disabled

相关命令

getsebool -a 查看selinux控制项
