GBase8a数据库集群IPV6部署和主机名部署

ipv6部署

1.以ipv6的形式相互ping通要安装集群的各个节点
①IPV4如何转化为IPV6:
192.168.103.74 10进制转化为16进制分别对应C0 A8 67 4A
所以也可以写成:2001:c0a8:674a/64
②将ipv6添加到网卡，如: ifconfig ens6 inet6 add 2001:c0a8:674a/64
注意:命令中的网卡名要写ip所在的网卡名。
一般执行ipconfig会发现有多个网卡，如下就有ens6、 etn0、 lo这三个网卡名， 但是最终要选择ens6,因为节点ip10.10.14.88在这个网卡上:
[root@xxx-node-0 ~]# ifconfig
ens6: flags=4163 <UP,BROADCAST,RUNNING,MULTICAST>mtu 1 500

③要安装集群的节点要相互ping通
ping命令: ping6 2001::c0a8:674a
注意: 节点要相互ping通， 单方向ping通是不行的

2.将demo.options中的ip都写成ipv6的形式并执行安装

主机名部署

1.配置/etc/hosts,将要安装集群的节点主机名都加进去，且每个节点都要配置。
[gbase@xxx-workstation-0 test1000]$ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
localhost localhost.localdomain localhost6 localhost6.localdomain6
10.10.2.132 xxx-workstation-0
10.10.0.61 xx-workstation-1
10.10.2.72 xxx-workstation-2
10.10.1.25 xxx-workstation-3

2.将demo.options中的ip都写成主机名的形式并执行安装
