Como instalar Magento paso a paso

Para instalar Magento

php 5.3 son las siguientes extensiones

PDO/MySQL
MySQLi
mcrypt
mhash
simplexml
DOM
SOAP

yum install php53-mcrypt

Primera parte

Primero, utilizaremos memcached como gestor de caché. Para ello ejecutamos las siguientes lineas:

Nota: para Centos 5.8, instalar estos repositorios para memcache:

>> rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm

>> rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-5.rpm

>> yum install memcached
 >> yum install php-memcache

Luego iniciamos memcached, un servicio de caché en memoria:

>> service memcached start

Seguidamente reiniciamos los servicios web:

>> /usr/local/psa/admin/bin/websrvmng -av
>> service httpd restart

También configuramos para que memcached se ejecute al inicio:

>> chkconfig memcached on

Ahora iremos a nuestra instalación de Magento y modificaremos la configuración de caché, editaremos el fichero /app/etc/local.xml:

<config>
     <global>
         ...
         <cache>
             <backend><![CDATA[memcached]]></backend><!-- apc / memcached / xcache / empty=file -->
             <slow_backend><![CDATA[database]]></slow_backend>
             <memcached><!-- memcached cache backend related config -->
                 <servers><!-- any number of server nodes can be included -->
                     <server>
                         <host><![CDATA[127.0.0.1]]></host>
                         <port><![CDATA[11211]]></port>
                         <persistent><![CDATA[1]]></persistent>
                         <weight><![CDATA[1]]></weight>
                         <timeout><![CDATA[10]]></timeout>
                         <retry_interval><![CDATA[10]]></retry_interval>
                         <status><![CDATA[1]]></status>
                     </server>
                 </servers>
                 <compression><![CDATA[0]]></compression>
                 <cache_dir><![CDATA[]]></cache_dir>
                 <hashed_directory_level><![CDATA[]]></hashed_directory_level>
                 <hashed_directory_umask><![CDATA[]]></hashed_directory_umask>
                 <file_name_prefix><![CDATA[]]></file_name_prefix>
             </memcached>
         </cache>
     </global>
     ...
 </config>

Reconfigurar el mysql con esto, editamos el /etc/my.cnf

# Disable Berkley DB functionality, saving memory

skip-bdb

#max_connections = 100

# tmp_table_size/max_heap_table_size: Default is 16MB, but this causes many

# temporary tables to be written to disk, and is ineffecient.

# Keep tmp_table_size and max_heap_table_size the same!

tmp_table_size = 128M # was 64M

max_heap_table_size = 128M # was 64M

### query-cache settings ###

query-cache-type = 1

query-cache-size = 84M # was 32M was 64M

query_cache_limit = 16M # was 1M was 8M

### Buffer size settings ###

#sort_buffer_size = 2M

# key_buffer_size is important for MyISAM tables.

key_buffer_size = 150M # was 16M

#join_buffer_size = 16M # was 2M

thread_cache_size = 8

# table_cache: Approximate by taking max_connections and multiplying by the

# largest number of tables that can be open for any join.

table_cache = 2048 # was 256 was 512 was 1024

### Timing options ###

interactive_timeout = 100

wait_timeout = 20

connect_timeout = 15

### Log slow queries ###

# Make sure you create this file before you start mysql or it will not work!

# Use the this command: touch /var/log/mysql.slow-queries.log && chown mysql:mysql /var/log/mysql.slow-queries.log

log-slow-queries=/var/log/mysql.slow-queries.log

# Duration a query must run (in seconds) to get logged

long_query_time = 1

### InnoDB settings ###

# See http://dev.mysql.com/doc/refman/5.0/en/innodb-configuration.html

# for InnoDB settings; They largely depend on your application.

innodb_buffer_pool_size = 1G

Finalmente, con esto ya tenemos una base rápida para que Magento funcione como la seda.

[mysqld_safe]

[isamchk]

Más tarde modificamos el .htacces para activas la compresión:

############################################
## enable apache served files compression

    SetOutputFilter DEFLATE
