Thanks, a lot bros.
但是我得系统里面应该是有足够的内存啊。

看日志 主要报错是这里：open files must not be less than 20000 (Current value: 1024)
可以尝试通过以下步骤调大 open files 数量

  1. echo 20480 > /proc/sys/fs/file-max
    2.加入以下配置，重启即可生效
    vim /etc/security/limits.conf
    hard nofile 20480
    soft nofile 20480

这个看下home目录下内存还有多大 ， demo 用的是home目录的磁盘空间
