Writing Codes in Your WordPress Posts

wordpress-love

While publishing tutorials you might have struggled to add blocks around “Codes” that you wish to share with your audience. Some people use plugins, but with a simple trick you can publish your codes with blocks without installing any plugin.

For an instance you can use following code in your posts; just make sure to use text editor instead of visual editor:

<Pre><PRE STYLE=”font-family:monospace;
font-size:0.95em;
width:90%;
border:red 2px solid;
color:white;
background-color:#000000; “>
bodHOST Bandwidth on Demand
</PRE><Pre>

How to install old and new version of PHP on cPanel server?

php

PHP 5.2 has become outdated and 5.3 officially mentioned as “End of Life” status, but many applications and custom scripts still work on these two platforms. So here is the guide for people who wish to use PHP 5.2 or 5.3 along with PHP 5.4 or 5.5 on a cPanel server and make use of both the versions at the same time.

Let’s assume the latest version of PHP 5.4 is installed on your server by default, but for some reason you need to install older version; follow the below steps to install old version of PHP.

1. Download and untar the older version of PHP that you wish to install. Here we assume that you are willing to install 5.3:

# mkdir /usr/local/buildphp53
# cd /usr/local/buildphp53
# wget http://museum.php.net/php5/php-5.3.9.tar.gz
# tar --strip-components=1 -zxvf php-5.3.*

2. Configure and install PHP

#./configure --prefix=/usr/local/php53 --enable-cgi --enable-bcmath
 --enable-calendar --with-mysql=/usr/bin -with-libdir=lib64 --with-gd
 --enable-mbstring (you can add more modules per your wish)
# make
# make install

3. Now add the PHP 5.3 handlers to Apache

# pico /usr/local/apache/conf/includes/pre_virtualhost_global.conf

Add the following:

Action application/x-httpd-php53 /cgi-sys/php53
AddType application/x-httpd-php53 .php53

Round Robin DNS

Round Robin DNS (1)

If you are unaware about this term, then it belongs to – domain pointing to two servers. Why we are discussing this today, because I have seen many people on public forums who wish to host their website on two servers.

Well, to host one domain on two servers you can use Round Robin DNS method. The concept is pretty simple. Just add additional “A” record (IP address) in DNS for your domain name which points to other server.

For example, if your website “yourdomain.com” hosted on two different servers, on one server the domain has the IP address 10.10.10.10 and on another server the domain users IP address 10.10.10.11, then make sure the nameservers of your domain “yourdomain.com” has two “A” records; one for each IP address (FYI, by default there is only one “A” record, as your site only exists on one IP address by default).
