Today I had an interesting problem.
When I ran:
# php test.php | less
The ‘less’ program entered input mode and the up and down arrow (and j, k keys) weren’t working.
Eventually I figured out a solution:
# php test.php < /dev/null | less
The PHP CLI seems to be interfering with the terminal and piping in /dev/null to PHP CLI stdin fixes the problem!
I had a problem with phpMyAdmin not using encrypted connections.
My server was correctly configured for SSL as indicated by:
SHOW VARIABLES LIKE '%ssl%'
However when I ran:
SHOW STATUS LIKE 'Ssl_cipher'
I got back a null result, indicating that the connection was not encrypted.
Eventually I figured out that the problem was caused by using the ‘mysqli’ provider for my connections in phpMyAdmin. When I switched my connections to use ‘mysql’ instead then encryption started working and an Ssl_cipher was reported.
I’d love to know what the actual problem is, but for now I’m just happy that my connections are actually encrypted. I spent a while hacking on the mysqli dbi interface to try and get it to play nice with SSL but I didn’t make any progress.
