详解 Linux系统集群的安装与并行计算

核心提示： # provides a remote login facility with authentication based on # privileged port numbers from trusted hosts. service login { disable = yes soc

# provides a remote login facility with authentication based on

# privileged port numbers from trusted hosts.

service login

{

disable = yes

socket_type = stream

wait = no

user = root

log_on_success += USERID

log_on_failure += USERID

server = /usr/sbin/in.rlogind

}

关于telnet的设置如下

# default: off

# description: The telnet server serves telnet sessions; it uses

# unencrypted username/password pairs for authentication.

service telnet

{

disable = yes

flags = REUSE

socket_type = stream

wait = no

user = root

server = /usr/sbin/in.telnetd

log_on_failure += USERID

}

所有这些服务在安装完系统之后都是默认为禁用的，要进行修改来打开这些服务。如要通过修改启动telenet则就需要改disable = yes为disable = no。对于其他的服务的启动的修改与之相同。若启动这些服务则只需要简单执行：

＃/etc/rc.d/init.d/xinetd restart

或重起计算机就可以使所作的更改生效。

C.在服务器节点编译、安装Fortran90编译器

先将Fortran90（我用的是Intel的）编译器拷贝至/tmp下，然后用tar xvfz fortran90 .tar.gzj解压缩。运行

./install

选择你所要安装的类型，如果你的机器是基于IA－32,就选择1。如果你的机器是基于It anium(TM)-based system就选择2。如果要停止安装，就选择X。选择过之后安回车进入下一步，此时会要求你选择 :
