解决方法：

查看mq连接数量：

rabbitmqctl list_connections | wc -l


rabbitmqctl list_connections

如果具柄不够，修改相关具柄数量：

  1. 在 /etc/security/limits.conf 添加：
mysql hard nofile 65535
mysql soft nofile 65535
 
* soft nofile 655350
* hard nofile 655350
 
* soft nproc 655350
* hard nproc 655350
 
* soft memlock unlimited
* hard memlock unlimited
  1. 创建文件夹：mkdir -p /etc/systemd/system/mariadb.service.d/
    添加文件 vim /etc/systemd/system/mariadb.service.d/limits.conf ， 内容如下：
[Service]
LimitNOFILE=65535
  1. 修改 vim /etc/my.cnf 添加 max_connections 项，如下：
[mysqld]
max_connections=30000
  1. 刷新配置：systemctl daemon-reload ;
  2. 重启服务：systemctl restart mariadb

2.Nova 计算节点发现

nova-manage cell_v2 discover_hosts --verbose

3.rabbitmq 句柄满了

  1. 编辑 vim /usr/lib/systemd/system/rabbitmq-server.service 文件，
    在 [Service] 下添加 LimitNOFILE=300000 ;如下：
[Service]
LimitNOFILE=300000
  1. 刷新配置：systemctl daemon-reload ;
  2. 重启服务：systemctl restart rabbitmq-server ;

在控制节点重新创建 keystone 认证用户：

source ~/keystonerc_admin

openstack user del zun
openstack user create --domain default --password zun zun
openstack role add --project services --user zun admin

openstack user del kuryr
openstack user create --domain default --password kuryr kuryr
openstack role add --project services --user kuryr admin

重启控制节点的zun服务：
systemctl restart zun-api zun-wsproxy

重启计算节点的zun服务：
systemctl restart kuryr-libnetwork
systemctl restart zun-compute

在 RabbitMQ 中使用 rabbitmqctl list_connections 命令查看TCP/IP连接的统计信息，命令格式：

rabbitmqctl list_connections [connectioninfoitem...]

注意，connectioninfoitem 参数用于指示哪些信息项会包含在结果集中，结果集的列顺序将匹配参数的顺序。connectioninfoitem 可选值如下：

pid：与连接相关的 Erlang 进程 ID

name：连接的名称。

port：服务器端口

host：返回反向 DNS 获取的服务器主机名称，或者 IP 地址，或者未启用。

peer_port：服务器对端端口。当一个客户端与服务器连接时，这个客户端的端口就是 peer_port。

peer_host：返回反向 DNS 获取的对端主机名称，或者 IP 地址，或者未启用。

ssl：是否启用 SSL

ssl_protocol：SSL 协议，如 tlsvl

ssl_key_exchange: SSL 密钥交换算法，如：rsa

ssl_cipher: SSL 加密算法，如：aes_256_cbc

ssl_hash: SSL 哈希算法，如：sha

peer_cert_subject：对端的 SSL 安全证书的主题，基于 RFC4514 的形式

peer_cert_issuer：对端 SSL 安全证书的发行者，基于 RFC4514 的形式

peer_cert_validity：对端 SSL 安全证书的有效期。

state：连接状态，包括 starting、tuning、opening、running、flow、blocking、blocked、closing 和 closed 这几种。

channels：该连接中的信道个数。

protocol：使用的 AMQP 协议的版本，当前是｛0,9,1｝或者｛0,8,0｝。注意，如果客户端请求的是 AMQP 0-9 的连接，RabbitMQ 也会将其视为 0-9-1。

auth_mechanism：使用的 SASL 认证机制，如 PLAIN、AMQPLAIN、EXTERNAL、RABBIT-CR-DEMO 等

user：与连接相关的用户名。

vhost：与连接相关的 vhost 的名称。

timeout：连接超时/协商的心跳间隔，单位为秒。

frame_max：最大传输帧的大小，单位为 B

channel_max：此连接上信道的最大数量。如果值 0，则表示无上限，但客户端一般会将 0 转变为 65535

client_properties：在建立连接期间由客户端发送的信息属性。

recv_oct：收到的字节数。

recv_cnt：收到的数据包个数。

send_oct：发送的字节数。

send_cnt：发送的数据包个数。

send_pend：发送队列大小。

connected_at：连接建立的时间戳。

示例

（1）如果没有指定 connectioninfoitem 信息，那么默认会显示 user、peer_host、peer_port 和 state 这几项信息。

D:\server\rabbitmq_server-3.9.11\sbin> rabbitmqctl list_connections
Listing connections ...
user    peer_host       peer_port       state
root    127.0.0.1       9365    running

（2）手动指定 connectioninfoitem 信息，例如：

D:\server\rabbitmq_server-3.9.11\sbin> rabbitmqctl list_connections user peer_host peer_port state
Listing connections ...
user    peer_host       peer_port       state
root    127.0.0.1       9365    running
