大数据处理Sahara
大数据处理Sahara.txt是我总结的命令，不包括Dashboard中的操作。
查看Sahara大数据集群的命令是sahara cluster-list（在我的文档最后面）。
--------------- 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
