GCDW元数据服务—Foundationdb Client安装部署

192.168.146.21、192.168.146.22、192.168.146.23  3个为gcdw集群准备的节点上安装foundationdb clent

• 三个节点上安装fdb客户端

192.168.146.21节点：

[root@rhel73-2 GCDW]# rpm -ivh foundationdb-clients-6.2.27-1.el7.x86_64.rpm

192.168.146.22节点：

[root@rhel73-2 GCDW]# rpm -ivh foundationdb-clients-6.2.27-1.el7.x86_64.rpm

192.168.146.23节点：

[root@rhel73-2 GCDW]# rpm -ivh foundationdb-clients-6.2.27-1.el7.x86_64.rpm

• 拷贝fdb server（192.168.146.20）上的外部访问文件到三个gcdw集群节点上，注意权限需跟fdb server保持一致

192.168.146.20节点上操作：

----rsync -p保持文件的权限属性 -o保持文件的属主属性 -g保持文件的属组属性
[root@rhel73-1 foundationdb]# ls
fdb.cluster foundationdb.conf
[root@rhel73-1 foundationdb]# rsync -p -o -g fdb.cluster [email protected]:/etc/foundationdb/
[email protected]'s password:
[root@rhel73-1 foundationdb]# rsync -p -o -g fdb.cluster [email protected]:/etc/foundationdb/
[email protected]'s password:
[root@rhel73-1 foundationdb]# rsync -p -o -g fdb.cluster [email protected]:/etc/foundationdb/
