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
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. Please see # http://www.rabbitmq.com/monitoring.html Restart=on-failure RestartSec=10 WorkingDirectory=/var/lib/rabbitmq ExecStart=/usr/sbin/rabbitmq-server ExecStop=/usr/sbin/rabbitmqctl stop ExecStop=/bin/sh -c "while ps -p $MAINPID >/dev/null 2>&1; do sleep 1; done" # See rabbitmq/rabbitmq-server-release#51 SuccessExitStatus=69 [Install] WantedBy=multi-user.target
然后重启rabbitmq
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
