Today I wanted to upgrade a php webserver with php5.6 . However the epel didn’t work .
After a yum clean all got this title error
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again
To fix this I needed to upgrade the ceritiface without epel .
yum upgrade ca-certificates –disablerepo=epel
After this all works.
Use following syntax to list the files for already INSTALLED package:
rpm -ql package-name
Use following syntax to list the files for RPM package:
rpm -qlp package.rpm
Well all know that this packet is not included into centos distro . To install and use php-mcrypt you have to install and use epel repository.
So here we go
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
rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm
yum update
yum install php-mcrypt*
Today I was trying to copy something from one server to other using scp . But I have a surprise while I was running the correct command scp file.tar root@server:/home well a error was occurred that scp is missing. Now on sending server the scp was because I see the output of usage: scp when I try on destination surprise no scp.
which scp
/usr/bin/which: no scp in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin)
So to install it just run :
yum install openssh-clients
If you have bellow error you should install mod_ssl
“Invalid command “SSLEngine”, perhaps misspelled or defined by a module not included in the server configuration”
The error message indicates that the module mod_ssl required to run SSL engine on a CentOS server is missing and needs to be installed.
Install the mod_ssl module using yum
yum install mod_ssl
Once it is installed, make sure to restart the Apache service
service httpd restart
