[辛建国]

I have installed puppetdb and puppetmaster(4.8),and I have exec "puppet agent -t and puppetdb ssl-setup -f " on the puppetdb server, when I exec "puppet agent -t" on puppet agent node,I get ssl error, I use "curl" command to check 8081 port of the puppetdb server on puppet master server, The puppetdb server looks like working normally. the curl command follow this:

 #curl  'https://bizpuppetdb.server:8081/pdb/query/v4/nodes'      --cacert /var/lib/puppetlabs/ssl/certs/ca.pem   --cert /var/lib/puppetlabs/ssl/certs/puppetserver.sogou.pem    --key /var/lib/puppetlabs/ssl/private_keys/puppetserver.sogou.pem

It return follow this: 
[{"deactivated":null,"latestreporthash":null,"factsenvironment":"production","cachedcatalogstatus":null,"reportenvironment":null.......}]

the ssl error like this:

2017-06-03 22:52:04 +0800 Puppet (warning): Error connecting to bizpuppetdb.server on 8081 at route /pdb/cmd/v1?checksum=330733bc8ffddc06ba3486ab3b62fd9723d0eb48&version=8&certname=bjzw_49_28.sogou-in.domain&command=store_report&producer-timestamp=1496501524, error message received was 'SSL_connect SYSCALL returned=5 errno=0 state=unknown state'.
