筆者日前部署openstack-ocata遇到一坑 glance服務無法正常啓動
首先就是服務正常使用
然後好好的，好好的 突然之間glance就不嫩用了！
查一下是服務沒有啓動，手動啓動一下，發現提示服務重啓次數太多，然後就自己掛了

於是
#grep 'fail' /lib/systemd/system/openstack-glance-api.service Restart=on-failure #sed -i '/fail/ s/^/#/g' /lib/systemd/system/openstack-glance-api.service #systemctl daemon-reload
再次重啓服務，報錯信息變成

發現無法找到paste文件，再次回頭來看看glance-api.conf 發現這麼一行
#If the paste configuration file is not found, the service will not start. # …………………… # (string value) #config_file = glance-api-paste.ini
那麼找找這個文件呢
#rpm -ql openstack-glance|grep glance-api-paste.ini > /dev/null # echo $? 1
木有，煤油，麻油！！
就是找不到了哦！難怪找不到
於是乎
ln -s/usr/share/glance/glance-api-dist-paste.ini /usr/share/glance/glance-api-paste.ini ln -s/usr/share/glance/glance-registry-dist-paste.ini /usr/share/glance/glance-registry-paste.ini
