1.服务器环境

node1:192.168.3.1

node2:192.168.3.2

2.主机名和hosts文件

node1: node1.xkops.com --主机名

[root@node1 ~]# tail -n 2 /etc/hosts

192.168.3.1 node1 node1.xkops.com

192.168.3.2 node2 node2.xkops.com

node2: node2.xkops.com --主机名

[root@node2 ~]# tail -n 2 /etc/hosts

192.168.3.1 node1 node1.xkops.com

192.168.3.2 node2 node2.xkops.com

3.关闭防火墙和selinux

node1:

service iptables stop

chkconfig iptables off

sed -i '/^SELINUX/s;enforcing;disabled;g' /etc/selinux/config

setenforce 0

node2:

service iptables stop

chkconfig iptables off

sed -i '/^SELINUX/s;enforcing;disabled;g' /etc/selinux/config

setenforce 0

4.配置本地yum源

node1:

mount /dev/sr0 /mnt

cd /etc/yum.repos.d/

mkdir backup && mv CentOS-* backup

[root@node1 yum.repos.d]# cat > CentOS-mnt.repo <<EOF

[CentOS6.5]

name=CT 6.5

baseurl=file:///mnt

enabled=1

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

EOF

[root@node1 yum.repos.d]# yum repolist

Loaded plugins: fastestmirror, refresh-packagekit, security

Determining fastest mirrors

repo id repo name status

CentOS6.5 CT 6.5 6,367

repolist: 6,367

node2:

mount /dev/sr0 /mnt

cd /etc/yum.repos.d/

mkdir backup && mv CentOS-* backup

[root@node2 yum.repos.d]# cat > CentOS-mnt.repo <<EOF

[CentOS6.5]

name=CT 6.5

baseurl=file:///mnt

enabled=1

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

EOF

[root@node2 yum.repos.d]# yum repolist

Loaded plugins: fastestmirror, refresh-packagekit, security

Determining fastest mirrors

repo id repo name status

CentOS6.5 CT 6.5 6,367

repolist: 6,367
