Stuff I do in Linux
To Install MySQL 5.6 and phpMyAdmin on Ubuntu just follow the command one by one bellow.
For phpMyAdmin to work, you need PHP to be installed. To install PHP 5.6 😉

This is one of major issue lot of web masters face now. As PHP 5.2 has reached end of life we are forced to seek options to migrate and test PHP applications in PHP 5.2 and 5.3. Raj COO from WebHostRepo.com has posted a nice blog post on how to achieve this.
Running PHP 5.3 along with PHP 5.2.x in cPanel servers.
I did all the steps as mentioned on the blog post except for one, I had a lengthier configure statement 😉

Happy migration 😉
For this installation I choose CentOS 6.3 minimal version. You can download the ISO from the mirrors or direct download it from SYNc yourself. Once the CentOS installation is completed make sure you are connected to Internet to update the latest libraries.
Note: These steps are done assuming you are logged in as root user
1. Please update the available updates for the OS and restart
|
1 2 |
# yum update # reboot |
2. Install EPEL (Extra Packages for Enterprise Linux) so that you can get all the needed libraries for compiling PHP
|
1 |
# rpm -ivh http://fedora.mirror.nexicom.net/epel/6/x86_64/epel-release-6-7.noarch.rpm |
3. Install Development Tools – Detailed User Guide
|
1 |
# yum groupinstall "Development Tools" |
4. Install MySQL Database client
|
1 |
# yum groupinstall "MySQL Database client" |
5. Install the following libraries which are required for different modules in PHP. Please make sure all the dependencies are met before installation
|
1 2 3 4 5 6 7 8 9 |
#yum install pcre-devel.x86_64 httpd.x86_64 httpd-devel.x86_64 wget.x86_64 #yum install mlocate.x86_64 mhash.x86_64 mhash-devel.x86_64 libssh2-devel.x86_64 #yum install openssl.x86_64 libssh2.x86_64 libxml2.x86_64 libxml2-devel.x86_64 #yum install libmcrypt.x86_64 libmcrypt-devel.x86_64 openssl-devel.x86_64 #yum install tidy.x86_64 libtidy.x86_64 libtidy-devel.x86_64 bzip2.x86_64 #yum install bzip2-devel.x86_64 libjpeg.x86_64 libXpm-devel.x86_64 #yum install libxslt.x86_64 libxslt-devel.x86_64 pcre.x86_64 pcre-devel.x86_64 #yum install libjpeg-devel.x86_64 libpng.x86_64 libpng-devel.x86_64 libXpm.x86_64 #yum install freetype-devel.x86_64 libtool-ltdl-devel.x86_64 pcre.x86_64 |
6. For this installation I planned to use the latest version of curl so I had to my custom curl compilation
|
1 2 3 4 5 6 7 |
# cd # wget http://c-ares.haxx.se/download/c-ares-1.9.1.tar.gz # tar xvzf c-ares-1.9.1.tar.gz # cd c-ares-1.9.1/ # ./configure # make # make install |
|
1 2 3 4 5 6 7 |
# cd # wget http://curl.haxx.se/download/curl-7.28.1.tar.gz # tar xvzf curl-7.28.1.tar.gz # cd curl-7.28.1/ # ./configure --with-libssh2 --enable-ares=/usr/local/ --enable-ipv6 # make # make install |
7. Download and compile PHP 5.3.19
|
1 2 3 4 5 6 7 |
# cd # wget http://php.net/get/php-5.3.19.tar.gz/from/in1.php.net/mirror # tar xvzf php-5.3.19.tar.gz # cd php-5.3.19/ # ./configure --prefix=/usr/local/php-5.3.19 --with-config-file-scan-dir=/usr/local/php5.3.19/php.d --with-apxs2 --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-mcrypt --with-mhash --enable-mbstring --with-gettext --with-openssl --with-curl=/usr/local/ --enable-calendar --enable-exif --enable-ftp --enable-zip --enable-soap --enable-bcmath --with-xmlrpc --with-tidy=/usr --with-bz2 --with-zlib --with-pear --with-kerberos --with-xsl --with-gd --enable-gd-native-ttf --with-jpeg-dir=/usr --with-png-dir=/usr --with-freetype-dir=/usr --with-pcre-regex --with-libdir=lib64 --with-pdo-mysql=mysqlnd # make # make install |
8. Copy php.ini
|
1 |
# cp /root/php-5.3.19/php.ini-production /usr/local/php-5.3.19/lib/php.ini |
9. Edit Apache conf check if “LoadModule” is present else add it.
|
1 |
# vi /etc/httpd/conf/httpd.conf |
LoadModule php5_module /usr/lib64/httpd/modules/libphp5.so
10. Set handler for Apache to handle PHP files
|
1 |
# vi /etc/httpd/conf/httpd.conf |
|
1 2 3 |
<FilesMatch \.php$> SetHandler application/x-httpd-php </FilesMatch> |
11. If you are not planning to install ZendGuardLoader skip to step 13 else make sure you have disabled SElinux. Detailed instructions
12. Install ZendGuardLoader
|
1 2 3 4 5 |
# cd # wget http://downloads.zend.com/guard/5.5.0/ZendGuardLoader-php-5.3-linux-glibc23-x86_64.tar.gz # tar xvzf ZendGuardLoader-php-5.3-linux-glibc23-x86_64.tar.gz # cd ZendGuardLoader-php-5.3-linux-glibc23-x86_64/ # mv php-5.3.x/ /usr/lib64 |
Edit /usr/local/php-5.3.19/lib/php.ini and add these lines to end
|
1 2 3 |
[Zend] zend_extension="/usr/lib64/php-5.3.x/ZendGuardLoader.so" zend_loader.enable=1 |
13. Restart you apache and you are set
|
1 |
# /etc/init.d/httpd restart |
It took a great deal of time to make this work and with lot of trial and errors. If anyone finds a better way to compile please do share it with me. All the best 😉
When you boot an Amazon Linux EC2 instance it boots with a 8GB EBS volume. If you need more space you need to add additional drives. For this you need to use EBS volumes.
Before you start the process please have look at the current partition blocks loaded in your server. You can do so using the contents of partition file.
|
1 2 3 4 |
bash-4.1# cat /proc/partitions major minor #blocks name 202 1 8388608 xvda1 |
Now you goto EBS volume manager in AWS console and create a new volume, make sure the zone is the same in which your EC2 instance is running.
Once the volume is created you need to attach this to an instance. You can right click on the created volume and say attach. Select the instance then device will populate automatically, you can either leave it or change if you need specific device name.
Now check the partition file again. You can see a new device being added.
|
1 2 3 4 5 |
bash-4.1# cat /proc/partitions major minor #blocks name 202 1 8388608 xvda1 202 128 26214400 xvdi |
The volume attached is not ready for use. It is like a new hard disk. You need to partition and format the same. In our case I am going to use the full disk as one partition. So I am going to skip the fdisk setup and jumping right into formatting the volume.

The format process can take few seconds just be patient. The drive is ready to use, and to do the same we need mount it.

If you wish this device to mount automatically when you reboot the server make sure you add this to your fstab file.

When I started which Amazon Cloud, I found these things in a hard way, hope this can help someone 🙂
