Headers and client library minor version mismatch

[ray]

Upgraded a WordPress site to v4.5 and started getting the following warning:

PHP Warning: mysqli_real_connect(): Headers and client library minor version mismatch. Headers:100023 Library:100113 in /home/user/public_html/wp-includes/wp-db.php on line 1489

LiteSpeed latest and CloudLinux 6 no CPanel server. The website is using PHP v7 from AltPHP and MariaDB on a remote DB server. The DB server has CPanel but not CloudLinux.

I ran /usr/bin/alt-php-mysql-reconfigure checking the config before and after (ls -la /opt/alt/php*/usr/lib*/php/modules/mysql*.so). Output is the same both times.

Strange thing is that issue happened after wordpress update. Can you please provide some more details?
1. What PHP version is used for this customer? Is it possible to get a link to full phpinfo() page?

2. What mariadb packages are installed for this php version?:

rpm -q alt-phpXY-mariadb10

rpm -q alt-phpXY-mariadb101

where XY is php version from step1

3. The output header of mysql -V from both serves.

Re: 1 & 2

The website is using PHP v7 from AltPHP and MariaDB on a remote DB server. The DB server has CPanel but not CloudLinux.

[bogdan.sh]

Then please provide from web server following output:

rpm -q alt-php70-mariadb10

rpm -q alt-php70-mariadb101

[ray]

The DB server does not have alt-php.

The web server is using DB on the remote server and alt-php70-mariadb101 is not installed locally.

# rpm -q alt-php70-mariadb10
alt-php70-mariadb10-7.0.4-1.el6.x86_64

[bogdan.sh]

Looks like you have to install few packages on web server, please do this:

yum clean all

yum install alt-php*mariadb101 alt-php-config --enablerepo=cloudlinux-updates-testing

/usr/bin/alt-php-mysql-reconfigure.py

[ray]

This is resolved. There was a railgun repo error that aborted install of those packages.

After installing, the original error is gone.

Many thanks!
