Error analysis

Before MARIADB does not come is similar error, but journalctl -xn after input, will display configuration error, correction my.cnf can but glance report this error how to solve? I haven't done anything yet, he said connected too fast, helpless under the thought of "Restart try, not on the points." Restart it, restart also useless, then remove the glance components, delete the database, delete Keystone link again, the result is still no eggs.

Similar to this service can not get the situation, according to personal experience to make the following summary

1. Configuration document error, revised configuration document, start again 2. Related folder/file permissions have problems, view permissions, modify permissions errors resolved

Because I am the root permission to operate, so the synchronization of the database is often used is glance-manage db_sync not a problem, synchronization is successful, the problem can not find the cause of the crash, Google did not find. When I entered the su -s /bin/sh -c "glance-manage db_sync" glance Fox tail finally revealed, synchronization error, error message:

Traceback (most recent): File"/usr/bin/glance-manage", lineTen,inch<module> Sys.exit (Main ()) File"/usr/lib/python2.7/site-packages/glance/cmd/manage.py", line273,inchMain Log.setup (' glance ') File"/usr/lib/python2.7/site-packages/glance/openstack/common/log.py", line460,inchSetup _setup_logging_from_conf (product_name, version) File"/usr/lib/python2.7/site-packages/glance/openstack/common/log.py", line529,inch_setup_logging_from_conf FileLog = Logging.handlers.WatchedFileHandler (logpath) File"/usr/lib64/python2.7/logging/handlers.py", line392,inch__init__ logging. filehandler.__init__ (self, filename, mode, encoding, delay) File"/usr/lib64/python2.7/logging/__init__.py", line902,inch__init__ streamhandler.__init__ (Self, Self._open ()) File"/usr/lib64/python2.7/logging/__init__.py", line925,inch_open stream = open (Self.basefilename, Self.mode) IOError: [Errno -] Permission denied:'/var/log/glance/api.log '

api.logPermissions have a problem, view

# ll /var/log/glance/api.log                                                          1147831122:25 /var/log/glance/api.log

Sure enough, change it to glance Group glance, sync again, restart again, OK

# chown -R glance:glance /var/log/glance/api.log# su -s /bin/sh -c "glance-manage db_sync" glance#  systemctl start openstack-glance-api.service
