@title = 'Where to look for errors' @nav_title = 'Where to look' @toc = true General ======= * Please increase verbosity when debugging / filing issues in our issue tracker. You can do this with adding i.e. `-v 5` after the `leap` cmd, i.e. `leap -v 2 deploy`. * We use the `example.org` domain for documentation purposes here, please replace it with the you domain. Firewall ======================= Every node in your provider has its own restrictive firewall, but you might have a network firewall in place as well that is not managed by LEAP platform. To see what ports and addresses must be open, run this command: workstation$ leap compile firewall If any of those are blocked, then your provider will not work. Webapp ====== Places to look for errors ------------------------- * `/var/log/apache2/error.log` * `/srv/leap/webapp/log/production.log` * `/var/log/syslog` (watch out for stunnel issues) * `/var/log/leap/*` Is haproxy ok ? --------------- curl -s -X GET "http://127.0.0.1:4096" Is couchdb accessible through stunnel ? --------------------------------------- * Depending on how many couch nodes you have, increase the port for every test (see /etc/haproxy/haproxy.cfg for the server/port mapping): curl -s -X GET "http://127.0.0.1:4000" curl -s -X GET "http://127.0.0.1:4001" ... Check couchdb acl as admin -------------------------- mkdir /etc/couchdb cat /srv/leap/webapp/config/couchdb.yml.admin # see username and password echo "machine 127.0.0.1 login admin password " > /etc/couchdb/couchdb-admin.netrc chmod 600 /etc/couchdb/couchdb-admin.netrc curl -s --netrc-file /etc/couchdb/couchdb-admin.netrc -X GET "http://127.0.0.1:4096" curl -s --netrc-file /etc/couchdb/couchdb-admin.netrc -X GET "http://127.0.0.1:4096/_all_dbs" Check couchdb acl as unpriviledged user --------------------------------------- cat /srv/leap/webapp/config/couchdb.yml # see username and password echo "machine 127.0.0.1 login webapp password " > /etc/couchdb/couchdb-webapp.netrc chmod 600 /etc/couchdb/couchdb-webapp.netrc curl -s --netrc-file /etc/couchdb/couchdb-webapp.netrc -X GET "http://127.0.0.1:4096" curl -s --netrc-file /etc/couchdb/couchdb-webapp.netrc -X GET "http://127.0.0.1:4096/_all_dbs" All URLs accessible ? --------------------- * https://example.org * https://api.example.org:4430/provider.json * https://example.org/ca.crt Check client config files ------------------------- * https://example.net/provider.json * https://example.net/1/config/smtp-service.json * https://example.net/1/config/soledad-service.json * https://example.net/1/config/eip-service.json Soledad ======= /var/log/soledad.log Couchdb ======= Places to look for errors ------------------------- * `/opt/bigcouch/var/log/bigcouch.log` * `/var/log/syslog` (watch out for stunnel issues) Bigcouch membership ------------------- * All nodes configured for the provider should appear here: 
    curl -s --netrc-file /etc/couchdb/couchdb.netrc -X GET 'http://127.0.0.1:5986/nodes/_all_docs'
* All configured nodes should show up under "cluster_nodes", and the ones online and communicating with each other should appear under "all_nodes". This example output shows the configured cluster nodes `couch1.bitmask.net` and `couch2.bitmask.net`, but `couch2.bitmask.net` is currently not accessible from `couch1.bitmask.net` 
    curl -s --netrc-file /etc/couchdb/couchdb.netrc 'http://127.0.0.1:5984/_membership'
    {"all_nodes":["bigcouch@couch1.bitmask.net"],"cluster_nodes":["bigcouch@couch1.bitmask.net","bigcouch@couch2.bitmask.net"]}
* Sometimes a `/etc/init.d/bigcouch restart` on all nodes is needed, to register new nodes Databases --------- * Following output shows all neccessary DBs that should be present. Note that the `user-0123456....` DBs are the data stores for a particular user. 
    curl -s --netrc-file /etc/couchdb/couchdb.netrc -X GET 'http://127.0.0.1:5984/_all_dbs'

    curl -s --netrc-file /etc/couchdb/couchdb.netrc -X  GET "http://127.0.0.1:5984/users/_design/User"
Is couchdb cluster backend accessible through stunnel ? ------------------------------------------------------- * Find out how many connections are set up for the couchdb cluster backend: 
    grep "accept = 127.0.0.1" /etc/stunnel/*
* Now connect to all of those local endpoints to see if they up. All these tests should return "localhost [127.0.0.1] 4000 (?) open" 
    nc -v 127.0.0.1 4000
    nc -v 127.0.0.1 4001
