Openstack 一直在调度中解决
查看日志/var/log/nova/nova-scheduler.log,/var/log/nova/nova-compute.log,均无报错查看/var/log/nova/nova-conductor.log报错为
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
max_connections = 4096
修改系统打开数
]# 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
重启mariadb
]# systemctl restart mariadb
如下错误
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'))")
上面的报错意思就是指client和MySQL server之间的链接断开了。
因为重启mariadb，其他openstack服务工作不正常了，需要重启其他服务
