安装openstack踩的一个坑

2017-11-14 727

Openstack Mitaka在图形化界面的时候出现以下报错：

 
         [root@linux-node1 ~]
         # openstack server create --flavor m1.tiny --image cirros --nic net-id=2d79dc77-be66-4850-af01-8e6946f16035 --security-group default --key-name mykey provider-instance

         .launchpad.net
         /nova/ 
         and attach the Nova API log 
         if 
         possible.

查了下网上资料，各种奇葩版本都有，但是对我的这个问题没有任何效果，核查下配置文件：

按照报错提示，检查我的nova配置，检查控制节点和计算节点，也没发现有啥异常

 
         grep 
         'ERROR' 
         /var/log/nova/
         * 
        
         grep 
         'ERROR' 
         /var/log/neutron/
         * 
        
         grep 
         'ERROR' 
         /var/log/glance/
         * 
        
         grep 
         'ERROR' 
         /var/log/keystone/
         *

后来排查发现（自己在编辑neutron的时候，忘记添加rpc_backend = rabbit）：

在计算节点后控制节点都添加后，重启neutron相关服务，然后再次执行创建云主机的操作

用dockerfile配置生成docker image并实现容器部署

前言： docker有个dockerfile 是什么东西，为什么我们要用他？简单的说：以前咱们docker run创建一个docker容器，有时候会附带不少的参数。比如: 1 dockerrun-d-p22-p8080:8080ruifengyun /ubunt-redis "redis-serverredis.conf&&/usr/sbin/sshd-D" 会发现很是麻烦。这个时候咱们可以创建编辑一个dockerfile文件，生成新的image，然后从这个新的镜像创建容器，容器里面相关联的启动项和端口，目录都是提前定义好的。原文：http://rfyiamcool.blog.51cto.com/1030776/1541081 cat Dockerfile 1 2 3 4 5 6 7 8 9 10 11 #配置redis FROMubuntu MAINTAINERruifengyun "ruifengyun@qq.com" ADD. /start .sh /root/start .sh RUNapt-getupdate RUNapt-get instal...

saltstack 分组

1、为什么要分组使用saltstack可以在很大程度上简化我们的工作，特别是在机器特别多的场景，并且业务较复杂的情况下，因此分组就显得非常重要了。 2、定义分组 1 2 3 4 5 root@mastersalt] #vim/etc/salt/master nodegroups: group01: 'L@node01.saltstack.com,node02.saltstack.com' group02: 'S@10.10.10.0/24' group03: 'E@node0[1-2].saltstack.com' 3、根据自己定义的分组进行测试 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 [root@mastersalt] #/etc/init.d/salt-masterrestart Stoppingsalt-masterdaemon:[确定] Startingsalt-masterdaemon:[确定] [root@mastersalt] #salt-Ngroup01test.ping node...
