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、


wKioL1le7AegSFrJAAAstyNfPrU999.png


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

[root@h1 ~]# 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


[root@h1 Packages]# rpm -e --nodeps mariadb-libs-5.5.47-1.el7_2.x86_64[root@h1 Packages]# rpm -qa mariadb-libs                              [root@h1 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%]
[root@h1 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

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
[root@controller 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



[root@controller 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。



[root@controller ~]# 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.

###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!
