OpenStack常用命令

nova-controller：

openstack endpoint list --long
nova service-list
nova list --all-tenants
cinder service-list
neutron net-list --all-tenants
glance image-list
openstack service list
openstack catalog list
openstack domain list
openstack image list
openstack host list

systemctl enable openstack-nova-api.service
systemctl enable openstack-nova-consoleauth.service
systemctl enable openstack-nova-scheduler.service
systemctl enable openstack-nova-conductor.service
systemctl enable openstack-nova-novncproxy.service

systemctl start openstack-nova-api.service
systemctl start openstack-nova-consoleauth.service
systemctl start openstack-nova-scheduler.service
systemctl start openstack-nova-conductor.service
systemctl start openstack-nova-novncproxy.service

systemctl status openstack-nova-api.service
systemctl status openstack-nova-consoleauth.service
systemctl status openstack-nova-scheduler.service
systemctl status openstack-nova-conductor.service
systemctl status openstack-nova-novncproxy.service

nova-computer:

systemctl enable libvirtd.service
systemctl enable openstack-nova-compute.service
systemctl start libvirtd.service
systemctl start openstack-nova-compute.service
openstack compute service list

数据库:

systemctl start mysqld
systemctl enable mysqld
systemctl status mysqld
mysql> show status like 'wsrep_%'; # 查看集群状态
检查mysql集群，看看三台节点的mysql是否都运行着
mysql -uroot -p`cat /etc/contrail/mysql.token` -e 'show status like "wsrep%"' 
该步骤仅在三个mysql中，至少有一个mysql已经正常运行的情况下执行
登入故障节点，cd /var/lib/mysql，执行rm -rf /var/lib/mysql/* （注意备份，注意备份后别把磁盘写满了），然后执行service mysql start 
该步骤仅在三个mysql都挂掉的场景下需要
登入每个mysql节点，cd /var/lib/mysql，通过ls -la检查ibdata1的修改时间，找到三台mysql节点上ibdata1修改时间最晚的那个（说明其mysql是最后停掉的），执行service mysql start --wsrep-new-cluster命令，启动mysql集群的第一个节点
mysql报错：ERROR! MySQL is not running, but lock file (/var/lock/subsys/mysql) exists
解决：删除  rm -f /var/lock/subsys/mysql 
mysql报错：ERROR! The server quit without updating PID file (/var/lib/mysql/mysql.pid)
解决：
1. cd /var/lib/mysql   
2.  touch mysql.pid   
3. chown  mysql mysql mysql.pid   
4. ps aux | grep mysql   
5. kill -9 进程号   
6. /etc/init.d/mysql start
上述解决不了尝试：rm -rf /var/lib/mysql/*  执行前删除 rm -f /var/lock/subsys/mysql 并且结束之前进程  ps aux | grep mysql   kill -9 进程号，/etc/init.d/mysql start

Haproxy：

systemctl start haproxy.service
systemctl stop haproxy.service
systemctl restart haproxy.service
systemctl enable haproxy.service

Pacemker：

systemctl start pcsd.service
systemctl enable pcsd.service
systemctl status pcsd.service
pcs status
pcs cluster standby node
pcs cluster unstandby node
pcs resource restart haproxy #重启haproxy 资源
pcs resource cleanup #清除错误日志后重启所有资源

crph：

ceph -s
ceph health detail
ceph osd pool create pool_name gp_num pgp_num #创建池

rabbitmq:

systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service
systemctl status rabbitmq-server.service -l
rabbitmqctl cluster_status
http://rabbitmq-server-IP:15672 #web访问
rabbitmq集群已经不正常的情况下执行
登入每台节点执行pkill -9 beam; pkill -9 epmd; 杀掉rabbitmq服务（三台同时执行） 
登入每台节点执行rm -rf /var/lib/rabbitmq/mnesia/     （三台同时执行） 
登入每台controller节点执行systemctl restart rabbitmq-server   （三台同时执行）

Memcache：

systemctl enable memcached.service
systemctl start memcached.service

Glance：

systemctl enable openstack-glance-api.service
systemctl enable openstack-glance-registry.service
systemctl start openstack-glance-api.service
systemctl start openstack-glance-registry.service
openstack image delete image-ID #删除镜像
