Look like something wrong with mysql 5.5 from CentAlt repo (install Kloxo-MR in Centos 6). Modified /etc/yum.repos.d/kloxo-mr.repo where:
...
[kloxo-mr-centalt]
name=Kloxo-MR - centalt - $basearch
baseurl=http://centos.alt.ru/repository/centos/6/$basearch/
enabled=1
gpgcheck=0
exclude=openssh* perl* mariadb*
...
to:
...
[kloxo-mr-centalt]
name=Kloxo-MR - centalt - $basearch
baseurl=http://centos.alt.ru/repository/centos/6/$basearch/
enabled=1
gpgcheck=0
exclude=openssh* perl*
...
and then run:
# make sure refresh for yum cache
yum clean all
# running yum update will be automatically change mysql to mariadb in Centos 6
yum update
# run again setup process
sh /usr/local/lxlabs/kloxo/setup.sh
I will update Kloxo-MR with enable mariadb from centalt repo.
