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 
[mysqld]
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
