系统级开启文件句柄
max-file系统级别的能够打开的文件句柄的数量，Centos7默认是794168。
Max-file 与 ulimit -n 的区别
注：对于服务器来说，file-max和ulimit都需要设置，否则会出现文件描述符耗尽的问题。
查看系统级别最大文件句柄数
[root@node01 ~]# cat /proc/sys/fs/file-max 95874
修改最大文件句柄数：永久生效
1、修改配置文件加入内核参数/etc/sysctl.conf
[root@node01 ~]# vi /etc/sysctl.conf # sysctl settings are defined through files in # /usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/. # # Vendors settings live in /usr/lib/sysctl.d/. # To override a whole file, create a new file with the same in # /etc/sysctl.d/ and put new settings there. To override # only specific settings, add a file with a lexically later # name in /etc/sysctl.d/ and put new settings there. # # For more information, see sysctl.conf(5) and sysctl.d(5). fs.file-max = 2000000 [root@node01 ~]# sysctl -p /etc/sysctl.conf fs.file-max = 2000000 [root@node01 ~]# cat /proc/sys/fs/file-max 2000000
50W并发可设置 = 999999
注：修改范围为系统所有进程可打开的最大文件句柄
