在CentOS 7下使用DevStack一键安装包安装OpenStack，突然来个报错，信息如下：
报错一、
解决方法：修改hosts文件，同步主机名
vim /etc/hosts
127.0.0.1 openstack
报错二、
ERROR : Error appeared during Puppet run: 192.168.1.201_mariadb.ppError: Execution of ‘/usr/bin/yum -d 0 -e 0 -y install mariadb‘ returned 1: Error: Package: 1:mariadb-5.5.44-2.el7.centos.x86_64 (dvd)
You will find full trace in log /var/tmp/packstack/20160704-142958-_jXSqZ/manifests/192.168.1.201_mariadb.pp.log
怀疑应该是软件问题
[[email protected] ~]# yum -d 0 -e 0 -y install mariadb-5.5.44-2.el7.centos.x86_64错误：软件包：1:mariadb-5.5.44-2.el7.centos.x86_64 (dvd) 需要：mariadb-libs(x86-64) = 1:5.5.44-2.el7.centos 已安装: 1:mariadb-libs-5.5.47-1.el7_2.x86_64 (@updates) mariadb-libs(x86-64) = 1:5.5.47-1.el7_2 可用: 1:mariadb-libs-5.5.44-2.el7.centos.x86_64 (dvd) mariadb-libs(x86-64) = 1:5.5.44-2.el7.centos 您可以尝试添加 --skip-broken 选项来解决该问题 您可以尝试执行：rpm -Va --nofiles --nodigest
一个是5.5.44 一个是5.5.47
[[email protected] Packages]# rpm -e --nodeps mariadb-libs-5.5.47-1.el7_2.x86_64[[email protected] Packages]# rpm -qa mariadb-libs [[email protected] Packages]# rpm -ivh mariadb-libs-5.5.44-2.el7.centos.x86_64.rpm准备中... ################################# [100%] 正在升级/安装... 1:mariadb-libs-1:5.5.44-2.el7.cento################################# [100%] [[email protected] Packages]# rpm -qa mariadb-libs mariadb-libs-5.5.44-2.el7.centos.x86_64
正常测试
报错三、
解决:
报错是 在用RDO模式 packstack安装openstack 最新版mitaka时出现的。
是在云上的环境
inet 192.168.1.7/24 brd 192.168.1.255 scope global dynamic eth0 有一个外网IP 42.62.X.X
查看日志
[[email protected] ~]# cd /var/log/keystone/[[email protected] keystone]# lskeystone.log2016-08-01 20:34:33.513 14145 ERROR keystone.common.wsgi DBConnectionError: (pymysql.err.OperationalError) (2003, "Can‘t connect to MySQL server on ‘x.x.x.x‘ ([Errno 110] Connection timed out)")2016-08-01 20:34:33.513 14145 ERROR keystone.common.wsgi2016-08-01 20:35:34.671 14150 WARNING oslo_db.sqlalchemy.engines [req-12a5fe87-1163-4fbb-a049-5225ea65a05a - - - - -] SQL connection failed. 10 attempts left.
查看数据库
MariaDB [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| cinder |
| glance |
| gnocchi |
| information_schema |
| keystone |
| mysql |
| neutron |
| nova |
| nova_api |
| performance_schema |
| test |
+--------------------+11 rows in set (0.00 sec)
MariaDB [(none)]> use keystone;
Database changed
MariaDB [keystone]> show tables;
Empty set (0.00 sec)
生成了库 没内容
看用户
MariaDB [mysql]> select host,user from user;
+-----------+----------------+
| host | user |
+-----------+----------------+
| % | cinder |
| % | glance |
| % | gnocchi |
| % | keystone_admin |
| % | neutron |
| % | nova |
| % | nova_api |
| 127.0.0.1 | keystone_admin |
| localhost | root |
+-----------+----------------+9 rows in set (0.00 sec)
权限是 %，应该是可以的，
参考 mysql授权localhost&%区别及一直授权错误解决办法
http://blog.csdn.net/tantexian/article/details/44861733
此处多说一句，此处配置%远程其他host有权限访问，那么在mysql的配置文件中 /etc/my.cnf，也需要做一些配置，将bind_address=0.0.0.0或者直接屏蔽掉此项，更多请自行查找资料。
如果想让外面host能访问数据库：（yunjisuan为root密码）
GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘yunjisuan‘;
flush privileges;
修改hosts
[[email protected] keystone]# cat /etc/hosts
127.0.0.1 controller
localhost localhost.localdomain localhost4 localhost4.localdomain4 ##在127.0.0.1也添加主机名字::1
localhost localhost.localdomain localhost6 localhost6.localdomain6 x.x.x.x controller
[[email protected] keystone]# mysql -ukeystone_admin -pEnter password:Welcome to the MariaDB monitor. Commands end with ; or \g. ##本机测试可以登录因为本人实在云上环境搭建的，只有一个eth0是内网，通过云是外网ip，现在不确定服务器 访问绑定的外网ip的方式是什么样的，
是直接eth0到外网ip，就回来了，， 还是过了路由再回来。如果是这样，就相当于远程访问mysql数据库。- -，关系好乱。
[[email protected] ~]# route -n ##这是默认路由Kernel IP routing tableDestination Gateway Genmask Flags Metric Ref Use Iface0.0.0.0 192.168.1.1 0.0.0.0 UG 100 0 0 eth0192.168.1.0 0.0.0.0 255.255.255.0 U 100 0 0 eth0所以现在要检查一下 安全组。 测试root 无法远程登录。
用别的机器测试 mysql服务器可以，安全组没有问题 MariaDB [mysql]> grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘xxxxxxxx‘; ####添加%，就可以远程登录了.
[[email protected] ~]# mysql -hip -p -ukeystone_admin
## 本地测试登录无问题。Enter password:Welcome to the MariaDB monitor. Commands end with ; or \g.MariaDB [mysql]> use keystone;Reading table information for completion of table and column namesYou can turn off this feature to get a quicker startup with -ADatabase changedMariaDB [keystone]> show tables;

###查看有表了再次执行，又有新的报错RROR : Error appeared during Puppet run: x.x.x.x_cinder.ppError: Could not prefetch cinder_type provider ‘openstack‘: Execution of ‘/usr/bin/openstack volume type list --quiet --format csv --long‘ returned 1: Unable to CONFIG_CINDER_NETAPP_ESERIES_HOST_TYPE=linux_dm_mp ##这是 cinder_typeMariaDB [keystone]> use cinderDatabase changedMariaDB [cinder]> show tables;Empty set (0.00 sec)
查看 cinder里面没有表，还是有问题。MariaDB [cinder]> use glance;Database changedMariaDB [glance]> show tables;Empty set (0.00 sec)
glance也没有生成表，，，只有keystone 的好了。Applying x.x.x.x_keystone.ppApplying x.x.x.x_glance.ppApplying x.x.x.x_cinder.pp
x.x.x.x_keystone.pp: [ DONE ] Testing if puppet apply is finished: x.x.x.x_cinder.pp [ \ ] $$$##卡在这里卸载数据库，从新测试，竟然可以了。。= =，我了个大去。感动老天了。。
| % | cinder |
| % | glance |
| 127.0.0.1 | keystone_admin |
总结：方法3个，1是在127.0.0.1 添加主机名，，2 重新设置一遍 root 在msyql 的权限% 3 卸载掉数据库，重新测试。
打算一会测试 用内网ip, 然后在路由器上做 80映射，这样应该会好一点。不知道行不行。简直是作死，在云上搭建openstack。。。。测试完。
**** Installation completed successfully ******
Additional information:
* Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
* File /root/keystonerc_admin has been created on OpenStack client host x.x.x.x . To use the command line tools you need to source the file.
* To access the OpenStack Dashboard browse to http://x.x.x.x /dashboard .
Please, find your login credentials stored in the keystonerc_admin in your home directory.
* Because of the kernel update the host x.x.x.x requires reboot.
* Because of the kernel update the host 127.0.0.1 requires reboot.

报错 四、
安装Mitaka
执行下列命令安装RDO库
yum install https://rdoproject.org/repos/rdo-release.rpm
安装CentOS openstack RPM repository
yum install centos-release-openstack-mitaka
更新系统包
yum update
安装packstack工具
yum install openstack-packstack
安装openstack Mitaka
packstack --allinone
执行这一步之后会花费一些时间
看到下面类似的信息，说明openstak mitaka已经安装完成了，同时可以看到dashboard的入口
从/root/keystonerc_admin文件里可以找到dashboard登陆信息
总结：其实每个简单得小报错都可能是未来的小财富，相信越努力就会越成功！
