我遇到的情况是，无论我做什么，graylog-server 都不会绑定到端口 12900。我已使用 github.com/graylog2/graylog-ansible-role 在两个 CentOS 7 VM 上安装了 graylog-server-1.1.6-1.noarch、elasticsearch-1.6.2-1.noarch、mongodb-org-server-2.6.10-1.x86_64、nginx-1.8.0-1.el7.ngx.x86_64 的 rpm。graylog-server 启动，在 /var/log/graylog/server.log 中不记录任何错误，但无法绑定到端口 12900。

我使用的 VM 有 4GB 的 RAM，而 JVM 配置为使用 1G。我想知道内存不足错误是否是由于启动了大量多播传输处理程序造成的。有什么想法吗？
答案1
我将其追溯到 /etc/graylog/server/server.conf 中的 elasticsearch_discovery_zen_ping_unicast_hosts 值。这是一个 Java 属性文件，因此值需要格式化如下：
elasticsearch_discovery_zen_ping_unicast_hosts = 10.1.10.134:9300
elasticsearch_discovery_zen_ping_unicast_hosts = 10.1.10.134:9300,10.1.10.133:9300
避免使用此类 YAML 格式。Graylog 代码（如 1.1.6 版）不会标记格式不正确的值。
elasticsearch_discovery_zen_ping_unicast_hosts = "10.1.10.134:9300"
elasticsearch_discovery_zen_ping_unicast_hosts = [ "10.1.10.134:9300" ]
