innobackupex using ssl doesn't work even though SSL does

ianwinterianwinter EntrantCurrent User Role Beginner
Trying to use innobackupex with SSL and cannot get it to work.


# innobackupex --version
innobackupex version 2.4.4 Linux (x86_64) (revision id: df58cf2)

# /etc/my.cnf [mysqld] block
ssl
ssl-ca=/etc/pki/MYSQL/ca-cert.pem
ssl-cert=/etc/pki/MYSQL/server-cert.pem
ssl-key=/etc/pki/MYSQL/server-key.pem

# $HOME/.my.cnf
[client]
user = __user__
password = __pass__
ssl-ca = /etc/pki/MYSQL/ca-cert.pem
ssl-cert = /etc/pki/MYSQL/client-cert.pem
ssl-key = /etc/pki/MYSQL/client-key.pem

If I use mysql on the command line to local host it works fine.

If I try the backup I get:

# innobackupex --defaults-file=/etc/my.cnf --slave-info --safe-slave-backup --compress --compress-threads=8 --stream=xbstream --parallel=8 ./ | nc 0.0.0.0 0000
160830 13:19:14 innobackupex: Starting the backup operation

IMPORTANT: Please check that the backup run completes successfully.
At the end of a successful backup run innobackupex
prints "completed OK!".

I've tried taking --defaults-file out, adding --defaults-extra-file etc. and still nothing.

How are you supposed to backup using SSL?
