2.0.1- 500 Internal Server Error: ArgumentError (NULL pointer given)

Since I'm running Percona XtraDB Cluster on the same server, and due to the Nagios error:

Additional Info: CRITICAL - cannot connect to information_schema. install_driver(mysql) failed: Cant locate DBD/mysql.pm in @INC (@INC contains: ...

I have removed the Percona-XtraDB-Cluster-shared by running:

rpm -e --nodeps Percona-XtraDB-Cluster-shared

then install Percona-SQL-shared and perl-DBD-MySQL.

After that, Redmine give me the error something like:

undefined method `init' for Mysql:Class

and what I've done to fix this problem is:

# gem uninstall mysql
# yum install Percona-XtraDB-Cluster-devel
# gem install mysql -v=2.8.1

but now I'm facing with 500 Internal Server error. The production.log said that:

Completed 500 Internal Server Error in 3ms

I suspect that it relate to the Percona-XtraDB-Cluster-shared - the libraries for MySQL clients. Any thoughts?

RE: 2.0.1- 500 Internal Server Error: ArgumentError (NULL pointer given) - Added by Quan Tong Anh almost 12 years ago

OK. The workaround is:

- uninstall perl-DBD-MySQL:

yum erase perl-DBD-MySQL

- reinstall from CPAN shell:

perl -MCPAN -e 'install DBD::mysql'

- remove Percona-SQL-shared and install Percona-XtraDB-Cluster-shared

yum remove Percona-SQL-shared && yum install Percona-XtraDB-Cluster-shared

- reinstall mysql gem:

gem uninstall mysql
gem install mysql -v=2.8.1
