MySQL Cluster on Amazon EC2
I created two cluster servers and one management server for MySQL Cluster
AMI: Minimal Fedora Core 8, 32-bit architecture, Apache 2.0, and Amazon EC2 AMI Tools
MySQL Cluster version 7.1
Fedora Version: 8
Security Group: default
1) Download RPM files
From http://www.mysql.com/downloads/cluster/#downloads all rpm files for Red Hat & Oracle Enterprise Linux for (x86, 32-bit).
2) In each instance
yum --enablerepo=remi erase mysql mysql-libs mysql-server mysqlclient15.i386 rpm -iv MySQL-Cluster-gpl-*
3) Config Management Server
Server IP ( ec2-79-11-111-11.eu-west-1.compute.amazonaws.com )
vi /var/lib/mysql-cluster/config.ini [NDBD DEFAULT] NoOfReplicas=2 [MYSQLD DEFAULT] [NDB_MGMD DEFAULT] [TCP DEFAULT] # Managment Server [NDB_MGMD] HostName=ec2-79-11-111-11.eu-west-1.compute.amazonaws.com # the IP of THIS SERVER # Storage Engines [NDBD] HostName=ec2-79-22-222-22.eu-west-1.compute.amazonaws.com # the IP of the FIRST SERVER DataDir= /var/lib/mysql-cluster [NDBD] HostName=ec2-79-33-333-33.eu-west-1.compute.amazonaws.com # the IP of the SECOND SERVER DataDir=/var/lib/mysql-cluster # 2 MySQL Clients # I personally leave this blank to allow rapid changes of the mysql clients; # you can enter the hostnames of the above two servers here. I suggest you dont. [MYSQLD] [MYSQLD] ndb_mgmd -f /var/lib/mysql-cluster/config.ini
The Management Server is now ready, you can check the conexions with the other servers doing this
ndb_mgm ndb_mgm> show Cluster Configuration --------------------- [ndbd(NDB)] 2 node(s) id=2 @79.22.222.22 (mysql-5.1.44 ndb-7.1.4, Nodegroup: 0, Master) id=3 @79.33.333.33 (mysql-5.1.44 ndb-7.1.4, Nodegroup: 0, Master) [ndb_mgmd(MGM)] 1 node(s) id=1 @79.11.111.11 (mysql-5.1.44 ndb-7.1.4) [mysqld(API)] 2 node(s) id=4 @79.22.222.22 (mysql-5.1.44 ndb-7.1.4) id=5 @79.33.333.33 (mysql-5.1.44 ndb-7.1.4)
4) Config Cluster Servers
Cluster Server IPs: (ec2-79-22-222-22.eu-west-1.compute.amazonaws.com and ec2-79-33-333-33.eu-west-1.compute.amazonaws.com )
/etc/my.cnf [mysqld] ndbcluster ndb-connectstring=ec2-79-11-111-11.eu-west-1.compute.amazonaws.com # the IP of the MANAGMENT SERVER [mysql_cluster] ndb-connectstring=ec2-79-11-111-11.eu-west-1.compute.amazonaws.com # the IP of the MANAGMENT SERVER /usr/sbin/ndbd --initial /etc/init.d/mysql start
5) Testing
You can check in FIRST or SECOND server this and it will be duplicated in both servers.
mysql -u root -p use test; CREATE TABLE ctest (i INT) ENGINE=NDBCLUSTER; INSERT INTO ctest () VALUES (1); SELECT * FROM ctest;
6) Starting and Shutting down the MySQL Cluster
Starting
Management Server: db_mgmd -f /var/lib/mysql-cluster/config.ini
Cluster Servers: ndbd
Shutting down
Management Server: ndb_mgm> shutdown
Notes
Error: ERROR 1005 (HY000): Can’t create table ‘test.ctest’ (errno: 157)
Try to track the error with SHOW WARNINGS; When I have this problem I had disabled SELinux with “setenforce 0″.
Error: There is no populating changes trough the cluster servers.
Make sure they are connected each other, you can check this from management server with ndb_mgm> SHOW
Also double check all servers are in the security group “default” to leave the ports open. (see image)

Setting up a Magento Server in Amazon Cloud EC2
How to create an instance for Magento in Amazon Cloud EC2
You can also get this ebs Image in Amazon EC2. Choose “426063643107/Magento 1.4.x on Fedora 8″
when you launch an instance in the tab “Community AMIs”
MySQL Admin Username: root Password: 123456
Once the image is initialized
a) Install Magento 1.4.1.1 (For demo store follow 5.1)
In your browser go to: http://YOUREC2NAME.compute-1.amazonaws.com/magento/
b) Install Magento 1.4.1.1 DEMO Version
In your browser go to: http://YOUREC2NAME.compute-1.amazonaws.com/magento-demo/
1) Choose the simplest Instance Fedora Core 8 (AMI Id: ami-df1e35ab)
Minimal Fedora Core 8, 32-bit architecture, Apache 2.0, and Amazon EC2 AMI Tools.
2) Installing Remi Repository with Apache, MySQL and PHP
wget http://rpms.famillecollet.com/remi-release-8.rpm rpm -Uvh remi-release-8.rpm vi /etc/apt/sources.list.d/remi.list # Uncomment: repomd http://rpms.famillecollet.com/ fc$(VERSION).$(ARCH) # Installing MySQL # yum --enablerepo=remi install mysql mysql-server mysql-devel # Installing Http Server with PHP # yum --enablerepo=remi install php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml # Config MySQL # /usr/bin/mysqladmin -u root password '123456' # Config Apache # # /etc/httpd/conf/httpd.con on Line 326 change AllowOverride None # to AllowOverride All # inside <Directory "/var/www/html"> ... </Directory> # /etc/php.ini Activate this line to read <? tags short_open_tag = On #Try it out with the usual script in /var/www/html/test.php <?php phpinfo(); ?>
3) Installing Exim Mail Server
yum install exim /etc/init.d/exim start mail -s "testing" your@emailaddress.com Testing purpose! . Cc: # Your Mail Server should be running properly
4) SFtp Server Access
# Just using a SFtp Client Server Vicomsoft Ftp Client # configure a new connection without password and use # the option "Use SSH keyfile (SFTP only)" to add your # .pem file # Or just use sshfs -i MYSECRETKEY.pem root@YOUREC2NAME.compute-1.amazonaws.com:/ /
5) Using ntsysv command choose the next services to start automatically
sendmail
httpd
mysqld
6) Optionally you can give NFS support to share files between images
#Server1 [root@server1]# vi /etc/exports /var/www/html *(rw) [root@server1]# /etc/init.d/rpcbind start [root@server1]# /etc/init.d/nfs start #Server2 [root@server2]# mount -o nolock ec2-79-xxx-xx-xxx.eu-west-1.compute.amazonaws.com:/var/www/html /mnt
7) Download and uncompress Magento versions in /var/www/html
CHANGELOG
File /etc/php.ini change short_open_tag = On

Speed up images and flash loading times in sites
.htaccess file
Header set Cache-Control “max-age=7257600, public”
It means that image files are all forced to use the local cache for 3 months.
Speeds many sites up considerably.

SSH Create Host – User Key to connect
# # SSH create a connection host key # # Setting up RSync over SSH with No Password # It's actually very simple. Just follow these few steps: # ---- 1 ---- # As the user you are going to be running rsync as, and on the machine you will be running rsync on, type: ssh-keygen -t rsa # Follow the prompts and use the defaults for the filenames it gives you. Don't enter in a passphrase, otherwise you will still be prompted for a password when trying to connect. # You should then have two new files in ~/.ssh, id_rsa and id_rsa.pub. # ---- 2 ---- # Open ~/.ssh/id_rsa.pub and copy the line in it to the ~/.ssh/authorized_keys file on the host you will be connecting to as the user you will be logging in as. # ---- 3 ---- # Now try it out. Try ssh'ing from the host you created the id_rsa* files on to the one you added a line to the authorized_keys file. You won't be prompted for a password any more. # ---- 4 ---- # Test it! # # Example: # # Host server: ls root/.ssh/ -rw-r--r-- 1 root root 424 Feb 26 15:38 authorized_keys -rw------- 1 root root 672 Feb 25 17:48 id_dsa -rw-r--r-- 1 root root 621 Feb 25 17:48 id_dsa.pub cat authorized_keys: ssh-rsa AA...L8vOA+w== ServerBackup@Server-Backups-Mac-Mini.local # User server: ls Users/ServerBackup/.ssh/ -rw------- 1 ServerBackup staff 1675 4 Jul 2009 id_rsa -rw-r--r-- 1 ServerBackup staff 424 4 Jul 2009 id_rsa.pub -rw-r--r-- 1 ServerBackup staff 1246 26 Feb 15:44 known_hosts cat known_hosts server.unexpectedit.com,172.123.123.238 ssh-rsa AAAAB3NzaC1...psoQ==
