修改/etc/security/limits.conf文件

添加：

*               soft    nofile          65535
*               hard    nofile          65535
*               soft    nproc           65535
*               hard    nproc           65535

查看/etc/security/limits.d目录是否有文件“90-nproc.conf”，没有的话新建该文件，文件

内容写为：

*               soft    nproc           65535
*               hard    nproc           65535

退出重新登录后，使用ulimit -a查看系统参数，成功后为：
