一般是由于服务器进程 打开文件数受限制

1.vim /etc/security/limits.conf 添加如下的行

# 解除服务器所有用户文件数 进程限制
*             soft       nofile      10240
*             hard       nofile      10240
*             soft       noproc      10240
*             hard       noproc      10240

2.保存后，再输入 ulimit -n 10240 回车即可生效。

3.提示 ulimit 命令 执行：

sudo sh -c "ulimit -n 65535 && exec su $LOGNAME"

再执行第二个步骤即可，

4.使用 ulimit -a 可以检查查看！
