原因
线上rabbitmq集群，发现rabbitmq描述符最多1024，还好暂时无用户量，赶紧修改
修改步骤
第一：修改系统文件描述符
cat /proc/sys/fs/file-max
/etc/sysctl.conf新增fs.file-max=1610391
然后sysctl -p
第二：修改用户系统描述符
|
1 2 3 4 5 |
vim /etc/security/limits.conf * soft nofile 100001 * hard nofile 100002 root soft nofile 100001 root hard nofile 100002 |
第三：centos7修改

[Unit] Description=RabbitMQ broker After=syslog.target network.target [Service] Type=notify User=rabbitmq Group=rabbitmq NotifyAccess=all TimeoutStartSec=3600 LimitNOFILE=65535 #添加这个 # The following setting will automatically restart RabbitMQ # in the event of a failure. systemd service restarts are not a # replacement for service monitoring.

然后重启rabbitmq

1 2 |
systemctl daemon-reload systemctl restart rabbitmq-server.service |
再次查看已经正常
注意：
系统描述符>用户描述符>rabbitmq的限制
