New 'node1.localdomain:1 (root)' desktop is node1.localdomain:1

Creating default startup script /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/node1.localdomain:1.log

[ OK ]
# cd ~/.vnc/
# vi xstartup
#!/bin/sh
export LANG
#unset SESSION_MANAGER
#exec /etc/X11/xinit/xinitrc

必选项：vnc viewer连接centos服务端时,注意防火墙对应的端口是否开放/或者关闭防火墙,否则会报10060(超时错误)，使用下面命令配置规则允许对应端口tcp包通过：
# iptables -I INPUT 1 -p tcp --dport 5901 -j ACCEPT
# service iptables save
# service iptables restart

问题
（1）Could not open/read file:///mnt/Packages/repodata/repomd.xml
把baseurl设置为file:///mnt/

1.1.3、node1-修改/etc/hosts文件

1、
1.1、
# vi /etc/hosts
#node1
192.168.0.3 node1.localdomain node1
192.168.0.5 node1-vip.localdomain node1-vip
10.10.10.31 node1-priv.localdomain node1-priv

#node2
192.168.0.4 node2.localdomain node2
192.168.0.6 node2-vip.localdomain node2-vip
10.10.10.32 node2-priv.localdomain node2-privi

#scan-ip
192.168.0.8 scan-cluster.localdomain scan-cluster

******在node2上做如上相同的操作

1.1.4、node1-配置dns，使scan-ip可以被解析

1、
1.1、安装bind服务
# ping 192.168.0.5 ##ping不通
# ping 192.168.0.15 ##ping不通

[root@node1 ～]# yum --disablerepo=* --enablerepo=c6-media install bind

1.2、配置/var/named/chroot/etc/named.conf 文件
*经过了解dns只需安装bind、bind-chroot、bind-utils
# yum --disablerepo=* --enablerepo=c6-media remove bind*
# yum --disablerepo=* --enablerepo=c6-media install bind bind-chroot bind-utils

1.3、配置/etc/named.conf 文件 不再是/var/named/chroot/etc/named.conf 文件
1.3.1、修改主配置文件
# cp -p /etc/named.conf named.conf.bak
# vi /etc/named.conf
listen-on port 53 { any; };
allow-query { any; };
# cp -p /etc/named.rfc1912.zones named.rfc1912.zones.bak

1.3.2、配置zone文件
# vi /etc/named.rfc1912.zones ##追加以下信息
zone "localdomain" IN {
type master;
file "forward.zone";
allow-update { none; };
};

zone "0.168.192.in-addr.arpa" IN {
type master;
file "reverse.zone";
allow-update { none; };
};

1.3.3、生成正向解析数据库文件
# cd /var/named/
# cp -p named.localhost forward.zone
# vi forward.zone ##正向解析数据库文件末尾加入如下
$TTL 1D
@ IN SOA node1.localdomain. root.localdomain. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
IN NS node1.localdomain.
node1 IN A 127.0.0.1
scan-cluster.localdomain IN A 192.168.0.8
scan-cluster IN A 192.168.0.8
