）

vi /etc/

[root@mdw ~]# sysctl -p

_forward = 0

_filter = 1

_source_route = 0

= 1

_uses_pid = 1

_syncookies = 1

error:

error:

error:

= 65536

= 68719476736

= 4294967296

error:

mmit_memory = 2

error:

_max_syn_backlog = 4096

_filter = 1

error:

_max_backlog = 10000

error:

= 4096

= 250 512000 100 2048

_tw_recycle = 1

_filter = 1

= 2048

2) vi /etc/security/

* softnofile 65536

* hardnofile 65536

* softnproc 131072

* hardnproc 131072

在

RHEL6.x

版本需要修改文件

/etc/security/limits.d/

，增加如下内容：

* softnproc 131072

* hardnproc 131072
