查看日志/var/log/nova/nova-scheduler.log,/var/log/nova/nova-compute.log,均無報錯

查看/var/log/nova/nova-conductor.log報錯為

2017-02-06 09:27:04.976 2206 ERROR oslo_messaging.rpc.server OperationalError: (pymysql.err.OperationalError) (1040, u'Too many connections')

修改mariadb配置文件

]# vim /etc/my.cnf.d/openstack.cnf [mysqld] max_connections = 4096

修改系統(tǒng)打開數(shù)

]# vim /etc/security/limits.conf * soft nofile 65536 * hard nofile 65536 ]# ulimit -SHn 65536]# vim /etc/sysctl.conf # max open files fs.file-max = 65536 ]# sysctl -p

重啟mariadb

]# systemctl restart mariadb

如下錯誤

2017-02-06 09:54:56.400 2213 ERROR nova.servicegroup.drivers.db OperationalError: (pymysql.err.OperationalError) (2006, "MySQL server has gone away (error(32, 'Broken pipe'))")

上面的報錯意思就是指client和MySQL server之間的鏈接斷開了。

因為重啟mariadb，其他openstack服務(wù)工作不正常了，需要重啟其他服務(wù)

]# openstack-service list neutron-dhcp-agent neutron-l3-agent neutron-linuxbridge-agent neutron-metadata-agent neutron-server openstack-glance-api openstack-glance-registry openstack-nova-api openstack-nova-compute openstack-nova-conductor openstack-nova-consoleauth openstack-nova-novncproxy openstack-nova-scheduler]# openstack-service restart
