在两个节点都要配置

这就是所说的大数据集群。


--------------- controller ----------------------------


yum -y install openstack-sahara


service mysqld stop

（先将/etc/my.cnf中的innodb_file_per_table删除，再执行下一条命令，否则会报错。）

openstack-config --set /etc/my.cnf mysqld max_allowed_packet 256M

（在/etc/my.cnf中重新添加innodb_file_per_table配置，有助于提升MySQL数据库性能。）

service mysqld start


mysql -uroot -p000000

这个地方操作多在dashboard界面操作。图片过多，暂不展示，

但是，可以在web界面清晰看到。左边出现了sahara这个栏目。
