CentOS6安裝配置rsh

基本信息：
節點一：
ip：192.168.8.166
主機名：hadrtest01
節點二：
ip：192.168.8.250
主機名：hadrtest02

1、兩節點分別安裝rsh,rsh-server包是否已經安裝

yum -y install rsh rsh-server

2、修改/etc/xinetd.d/rlogin確保disable = no這一行

# default: on
# description: rlogind is the server for the rlogin(1) program. The server \
# provides a remote login facility with authentication based on \
# privileged port numbers from trusted hosts.
service login
{
socket_type = stream
wait = no
user = root
log_on_success += USERID
log_on_failure += USERID
server = /usr/sbin/in.rlogind
disable = no
}

節點二同樣修改

3、修改/etc/xinetd.d/rsh確保disable = no這一行

[root@hadrtest01 ~]# cat /etc/xinetd.d/rsh
# default: on
# description: The rshd server is the server for the rcmd(3) routine and, \
# consequently, for the rsh(1) program. The server provides \
# remote execution facilities with authentication based on \
# privileged port numbers from trusted hosts.
service shell
{
socket_type = stream
wait = no
user = root
log_on_success += USERID
log_on_failure += USERID
server = /usr/sbin/in.rshd
disable = no
}

節點二同樣修改

4、編輯/etc/securetty，添加rexec、rsh、rlogin三行

echo "
rexec 
rsh 
rlogin
" >> /etc/securetty

5、編輯/etc/hosts，添加兩節點的ip，主機名

[root@hadrtest01 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.8.166 hadrtest01
192.168.8.250 hadrtest02

節點二同樣修改

6、修改~/.rhosts ,添加節點一，節點二主機名，ip

[root@hadrtest01 ~]# cat ~/.rhosts 
hadrtest01 root
hadrtest02 root

[root@hadrtest02 ~]# cat ~/.rhosts
hadrtest01 root
hadrtest02 root

7、兩節點分別啟動服務
重啟：

service xinetd restart

開機啟動:

chkconfig xinetd on

8、測試
節點一：

[root@hadrtest01 ~]# rsh hadrtest02
Last login: Tue Feb 16 17:44:56 from hadrtest01
[root@hadrtest02 ~]#
