红帽全球峰会第 8 章 调整 KDC 的性能
要优化 Kerberos 密钥分发中心(KDC)的性能，它负责验证用户、主机和服务，根据您的部署的流量模式调整密钥参数。
8.1. 调整 KDC 侦听队列的长度

您可以通过在 /var/kerberos/krb5kdc/kdc.conf 文件的 [kdcdefaults] 部分中设置 kdc_tcp_listen_backlog 选项，来调整 KDC 守护进程的监听队列长度的大小。对于某些有大量 Kerberos 流量的 IdM 部署，默认值 5 可能太低，但如果设置的值太高会降低性能。

| 有效范围 |

流程
-
在文本编辑器中打开
/var/kerberos/krb5kdc/kdc.conf文件。 将 TCP 侦听功能设置为所需值，如
7。[kdcdefaults] ... kdc_tcp_listen_backlog = 7-
保存并关闭
/var/kerberos/krb5kdc/kdc.conf文件。 - 重启 KDC 来加载新设置。
