The arrival of complete version of PHP 7 a few weeks back has assured its users of new features and much needed optimizations, along with corresponding speed improvements. Installing PHP7 on a CentOS machine is so simple and this article sheds light on it.

Installing PHP 7

Q

How do I change the sort ordering of textual data in PostgreSQL?

A

PostgreSQL sorts textual data according to the ordering that is defined by the current locale, which is selected during initdb.

Q

How do I control connections from other hosts?

A

, PostgreSQL only allows connections from the local machine using Unix domain sockets or TCP/IP connections. Other machines will not be able to connect unless you modify listen_addresses in the postgresql.conf file, enable host-based authentication by modifying the $PGDATA/pg_hba.conf file, and restart.

Q

A

try the command as follow " yum clean metadata yum clean all"

Q

What happened to the database dump feature in php Admin?

You need to configure phpPgAdmin (in the config.inc.php file) to point to the location of the pg_dump and pg_dumpall utilities on your server. Once you have done that, the database export feature will appear.
