初始化数据库
♾️ python 代码:mysql -u root -p000000创建placement数据库并授权
♾️ python 代码: CREATE DATABASE placement;
GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' IDENTIFIED BY '000000';
GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' IDENTIFIED BY '000000';
exit演示如下
♾️ python 代码:[root@controller ~]# mysql -u root -p000000

总结
这一次的搭建比较简单，前面我也没有出过错，后面的nova，就有报错的痕迹了，值得注意的是，如果说没有报错，但是就是有服务没有起来的话，直接重启，然后查看防火墙和selinux是不是又他妈的偷偷启动了，关闭就好了，这是血与泪的教训。
