Configs #

Redhat 6:

Language: /etc/sysconfig/i18n to “zh_CN.UTF8”
TimeZone: /etc/sysconfig/clock to “China/Shanghai”

SElinux > Allow apache to use remote DB: #

setsebool -P httpd_can_network_connect_db=1

SELinux > Allow apache /php to send email: #

sudo setsebool -P httpd_can_sendmail 1## with the “-P” for persistent (across reboots).

Trouble shooting: #

"You have new mail ...": install mailx
updatedb / locate: command not found: install mlocate

Install RHEL EPEL Repo on Centos 6 #

OBS: when installing CentOS, it is suggested to install the “with updates” version.

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
sudo rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm
sudo vim /etc/yum.repos.d/remi.repo
