答案1

httpd 资源确实似乎正在运行（根据您显示的 pcs status 输出）。也许在 Pacemaker 监控服务时有某些东西停止了服务，这会引发您在上面看到的错误，并触发恢复。

如果您在日志中（在 DC：“当前 DC：vda-zabserver-b - 具有仲裁的分区”）查找“LogActions”，您应该会看到 Pacemaker 在资源上执行的任何启动/停止/恢复/重新启动/离开操作。

如果是这种情况，您将需要确保除了 Pacemaker 之外没有任何东西在管理这些集群服务；Pacemaker 期望成为唯一启动和停止这些服务的东西。

您可以通过运行以下命令来清除错误：

# pcs resource cleanup httpd

返回代码 7 通常表示当 Pacemaker 检查其状态时该服务未运行。

我通过取消注释 httpd.conf 中的状态 URL 并以此方式创建资源来修复此问题。不过请确保http://localhost/服务器状态在添加资源之前可以访问

pcs resource create httpd apache configfile="/etc/httpd/conf/httpd.conf" statusurl="http://localhost/server-status" op monitor interval=5s --group zabbix-cluster
