容器部署的openstack进入数据库流程、查看install目录流程、容器部署使用virsh命令流程【查看计算节点上的虚拟机信息】
说明
- 何为容器部署，无需多说吧？
如下 计算节点的容器
进入数据库方法【控制节点】
获取nova密码
首先获取nova数据库的密码
控制节点执行：grep mysql /etc/kolla/nova-api/nova.conf【目录不是固定的，可以通过find命令查找nova.conf文件查看】，如下，1Gr2qFT0LmZ46v0GrFUJmXEFTTBHWVWzofxkxLAn就是密码[root@controller01 ~]# grep mysql /etc/kolla/nova-api/nova.conf connection = mysql+pymysql://nova:1Gr2qFT0LmZ46v0GrFUJmXEFTTBHWVWzofxkxLAn@1.2.101.240:3306/nova connection = mysql+pymysql://nova_api:Msgi5FFcPqlkT26lDaH7wcceAE1cQNbsyzQ6TbzQ@1.2.101.240:3306/nova_api [root@controller01 ~]#- 1

查看数据库容器
肯定会有一个数据库容器的，如我这是
mariadb[root@controller01 ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES openvswitch_vswitchd ... 0e12fe84c1d1 1.2.101.32:9980/kolla/centos-binary-iscsid:5.0.6.6 "kolla_start" 2 years ago Up 2 years iscsid fcaf8d58d941 1.2.101.32:9980/kolla/centos-binary-mariadb:5.0.6.6 "kolla_start" 2 years ago Up 23 months mariadb 85cb175184b1 1.2.101.32:9980/kolla/centos-binary-memcached:5.0.6.6 "kolla_start" 2 years ago Up 23 months memcached ...

查看install目录流程【计算节点】
查看容器
- nova_compute 和nova_libvirt 这2个容器都是可以查看实例目录的，进任意一个都行

进入容器
- 进入nova_libvirt查看
我这的实例目录是/var/lib/nova/instances/【你的如果不是就用find搜索instances即可】
[root@compute30 ~]# docker exec -it nova_libvirt bash (nova-libvirt)[root@compute30 /]# cd /var/lib/nova/instances/ (nova-libvirt)[root@compute30 instances]# ls 19ec09a5-151b-4111-a4bd-636d10794912 b0cc2a24-1c9c-46d3-bd3b-ef90b78c871c b7a9b013-d364-4588-b8ae-f6cbd4ba704f _base daaf62bf-ed53-4a16-892a-798ac427254b f8a41b8e-c989-4645-9f18-fdeee075c8d9 4fad6565-b24b-4617-bb8e-4110ebd43026 b3b091ee-fcbc-4a2a-8a09-7250ee144f3c b99dc9e3-0d6b-4b3b-965a-d4e10791c4f0 compute_nodes f76744d4-afbc-4d92-80e0-cbdb7b30be15 locks (nova-libvirt)[root@compute30 instances]# cd 19ec09a5-151b-4111-a4bd-636d10794912/ (nova-libvirt)[root@compute30 19ec09a5-151b-4111-a4bd-636d10794912]# ls console.log (nova-libvirt)[root@compute30 19ec09a5-151b-4111-a4bd-636d10794912]#- 1

使用virsh命令流程【计算节点】
查看容器
- virsh命令是基于libvirt服务的，所以我们这需要进入nova_libvirt容器
