Linux 版本 | OpenStack版本 | CentOS7 | Train | 一、KeyStone服务
遇到安装KeyStone组件报错
- [root@controller ~]# yum -y install openstack-keystone httpd mod_wsgi
- Error: Package: python2-qpid-proton-0.22.0-1.el7.x86_64 (centos-openstack-queens)
- Requires: qpid-proton-c(x86-64) = 0.22.0-1.el7
- Available: qpid-proton-c-0.14.0-2.el7.x86_64 (extras)
- qpid-proton-c(x86-64) = 0.14.0-2.el7
- Available: qpid-proton-c-0.17.0-4.el7.x86_64 (centos-openstack-queens)
- qpid-proton-c(x86-64) = 0.17.0-4.el7
- Available: qpid-proton-c-0.22.0-1.el7.x86_64 (centos-openstack-queens)
- qpid-proton-c(x86-64) = 0.22.0-1.el7
- Installing: qpid-proton-c-0.37.0-1.el7.x86_64 (epel)
- qpid-proton-c(x86-64) = 0.37.0-1.el7
- You could try using --skip-broken to work around the problem
- You could try running: rpm -Va --nofiles --nodigest
复制代码 解决方案:
- [root@controller ~]# yum install -y python2-qpid-proton-0.22.0-1.el7.x86_64
复制代码 二、Placement服务
安装OpenStack-placement-api时遇到没有这个软件包
解决方法:
在阿里云官网上进入CentOS源地址:
centos-7-cloud-x86_64安装包下载_开源镜像站-阿里云 (aliyun.com)
重新配置一个yum源
- [root@controller ~]# yum install openstack-placement-api
- Loaded plugins: fastestmirror
- Loading mirror speeds from cached hostfile
- * base: mirrors.aliyun.com
- * extras: mirrors.aliyun.com
- * updates: mirrors.aliyun.com
- No package openstack-placement-api available.
- Error: Nothing to do
复制代码- [root@controller ~]# vim /etc/yum.repos.d/openstack.repo
- [openstack-train]
- name=openstack-train
- baseurl=https://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-train/
- gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7
- gpgcheck=1
- [root@controller ~]# yum clean all
- Loaded plugins: fastestmirror
- Cleaning repos: openstack-train

复制代码 三、Nova摆设完毕后启动系统
- net_mlx5: cannot load glue library: libibverbs.so.1: cannot open shared object file: No such file or directory
- net_mlx5: cannot initialize PMD due to missing run-time dependency on rdma-core libraries (libibverbs, libmlx5)
- PMD: net_mlx4: cannot load glue library: libibverbs.so.1: cannot open shared object file: No such file or directory
- PMD: net_mlx4: cannot initialize PMD due to missing run-time dependency on rdma-core libraries (libibverbs, libmlx4)
- net_mlx5: cannot load glue library: libibverbs.so.1: cannot open shared object file: No such file or directory
- net_mlx5: cannot initialize PMD due to missing run-time dependency on rdma-core libraries (libibverbs, libmlx5)
- PMD: net_mlx4: cannot load glue library: libibverbs.so.1: cannot open shared object file: No such file or directory
- PMD: net_mlx4: cannot initialize PMD due to missing run-time dependency on rdma-core libraries (libibverbs, libmlx4)
- [root@controller ~]#
复制代码 解决方法:
实验 yum install -y libibverbs
- [root@controller ~]# yum install -y libibverbs
复制代码 四、查抄单元和放置API是否乐成工作发现未找到主机名
- [root@controller ~]# nova-status upgrade check
- +------------------------------------------------------------------+
- | Upgrade Check Results |
- +------------------------------------------------------------------+
- | Check: Cells v2 |
- | Result: Failure |
- | Details: No host mappings found but there are compute nodes. Run |
- | command 'nova-manage cell_v2 simple_cell_setup' and then |
- | retry. |
- +------------------------------------------------------------------+
- | Check: Placement API |
- | Result: Success |
- | Details: None |
- +------------------------------------------------------------------+
- | Check: Ironic Flavor Migration |
- | Result: Success |
- | Details: None |
- +------------------------------------------------------------------+
- | Check: Cinder API |
- | Result: Success |
- | Details: None |
- +------------------------------------------------------------------+
复制代码 解决方案:
这种多半是因为盘算节点服务没有启动而导致的,查抄盘算节点nova组件服务是否正常后,在控制节点实验 nova-manage cell_v2 simple_cell_setup 命令即可规复
- [root@controller ~]# nova-manage cell_v2 simple_cell_setup
- Cell0 is already setup
- [root@controller ~]# nova-status upgrade check
- +--------------------------------+
- | Upgrade Check Results |
- +--------------------------------+
- | Check: Cells v2 |
- | Result: Success |
- | Details: None |
- +--------------------------------+
- | Check: Placement API |
- | Result: Success |
- | Details: None |
- +--------------------------------+
- | Check: Ironic Flavor Migration |
- | Result: Success |
- | Details: None |
- +--------------------------------+
- | Check: Cinder API |
- | Result: Success |
- | Details: None |
- +--------------------------------+
复制代码 五、Placement列出可用的资源类和特征报错
- [root@controller ~]# openstack --os-placement-api-version 1.2 resource class list --sort-column name
- Expecting value: line 1 column 1 (char 0)
复制代码 解决方案:
①.给Apache授权(修改配置文件)
②.重启httpd服务
- [root@controller ~]# vim /etc/httpd/conf.d/00-placement-api.conf
- Listen 8778
- <VirtualHost *:8778>
- WSGIProcessGroup placement-api
- WSGIApplicationGroup %{GLOBAL}

- [root@controller ~]# systemctl restart httpd.service
复制代码 再次尝试:
- [root@controller ~]# openstack --os-placement-api-version 1.2 resource class list --sort-column name

复制代码 六、进入dashboard表现无法加载实例
1.解决方案:
①.进入MySQL:手动设定最大毗连次数,最大毗连次数设置为500
②.我们可以看到默认的最大毗连次数是214,我们手动修改到500
- mysql -u root -p
- MariaDB [(none)]> show global variables like '%max_conn%';
- +-----------------------+-------+
- | Variable_name | Value |
- +-----------------------+-------+
- | extra_max_connections | 1 |
- | max_connect_errors | 100 |
- | max_connections | 214 |
- +-----------------------+-------+
- 3 rows in set (0.01 sec)
- MariaDB [(none)]> set global max_connections=500
- MariaDB [(none)]> show global variables like '%max_conn%';
- +-----------------------+-------+
- | Variable_name | Value |
- +-----------------------+-------+
- | extra_max_connections | 1 |
- | max_connect_errors | 100 |
- | max_connections | 594 |
- +-----------------------+-------+
- 3 rows in set (0.002 sec)
复制代码 2.解决方法(二):
①.手动修改配置文件,设置最大毗连数
- [root@controller ~]# vim /usr/lib/systemd/system/mariadb.service
- [Service]
- Type=notify
- User=mysql
- Group=mysql
- LimitNOFILE=10000 ==>添加上
- LimitNPROC=10000 ==>添加上
- [root@controller ~]# systemctl --system daemon-reload
- [root@controller ~]# systemctl restart mariadb.service
- [root@controller ~]# mysql -u root -p
- MariaDB [(none)]> show global variables like '%max_conn%';
- +-----------------------+-------+
- | Variable_name | Value |
- +-----------------------+-------+
- | extra_max_connections | 1 |
- | max_connect_errors | 100 |
- | max_connections | 4096 |
- +-----------------------+-------+
- 3 rows in set (0.012 sec)
复制代码 七、dashboard controller拒绝了我们的毗连哀求
1.解决方案:
①.在C:\Windows\System32\drivers\etc\目录下,修改hosts文件
②.添加上"控制节点IP地址 和控制节点的主机名",作为主机名和IP地址之间的映射文件
这个时候我们就发现可以从dashboard访问实例控制台
