一。更新系统 yum update yum install kernel* reboot
二.安装编译环境（可选）
 yum install gcc gcc-c++ gcc-g77 flex bison autoconf automake bzip2-devel zlib-devel ncurses-devel libjpeg-devel libpng-devel libtiff-devel freetype-devel pam-devel openssl-devel libxml2-devel
 三。安装lamp
2 -
Install mysql yum mysql mysql-server mysql-libs Centos won’t need mysql-libs (centos不需要安装mysql-libs，因为装系统的时候已经装好了)
3 – Install apache, php and required modules yum install httpd php php-xml php-pear php-mhash php-mcrypt php-mysql php-pdo php-gd
四。去掉没必要的系统服务
chkconfig NetworkManager off chkconfig NetworkManagerDispatcher off chkconfig anacron off chkconfig atd off chkconfig bluetooth off chkconfig cpuspeed off chkconfig cups off chkconfig gpm off chkconfig hidd off chkconfig ip6tables off chkconfig iptables off chkconfig irda off chkconfig mdmonitor off chkconfig mdmpd off chkconfig pcscd off chkconfig portmap off chkconfig yum-updatesd off chkconfig smartd off service smartd stop service NetworkManager stop service NetworkManagerDispatcher stop service anacron stop service atd stop service bluetooth stop service cpuspeed stop service cups stop service gpm stop service hidd stop service ip6tables stop service iptables stop service irda stop service mdmonitor stop service mdmpd stop service pcscd stop service portmap stop service yum-updatesd stop
五。安装magento
 如果遇到这个问题PHP Extension “mcrypt” must be loaded
解决办法： yum install php-mcrypt
 1.下载magento到linux主机中：
 cd /var/www/html wget http://www.magentocommerce.com/downloads/assets/1.1.8/magento-1.1.8.tar.gz wget http://www.magentocommerce.com/downloads/assets/1.1.2/magento-sample-data-1.1.2.tar.gz tar -zxvf magento-1.1.8.tar.gz tar -zxvf magento-sample-data-1.1.2.tar.gz mv magento-sample-data-1.1.2/media/* magento/media/ mv magento-sample-data-1.1.2/magento_sample_data_for_1.1.2.sql magento/data.sql mv magento/* magento/.htaccess . chmod o+w var var/.htaccess app/etc chmod -R o+w media mysql -h localhost -u root -pDBPASS DBNAME < data.sql ./pear mage-setup . ./pear install magento-core/Mage_All_Latest-stable rm -rf downloader/pearlib/cache/* downloader/pearlib/download/* rm -rf magento/ magento-sample-data-1.1.2/ rm -rf magento-1.1.8.tar.gz magento-sample-data-1.1.2.tar.gz data.sql
安装magento
二、创建数据库 mysql -u root -p mysql>create database magento;
如果你需要sample data的话, 现在就要导入了.
mysql>use magento mysql>source path/data_file.sql
三、设置目录权限 cd chmod 0+w app/etc var var/.htaccess chmod -R o+w media 之后,在浏览器访问Magento的地址即可开始安装. 这里就不详细叙述了. 另外,在使用Magento Connect的时候会出现Permissions的问题. 只需要执行一下命令:
 cd find . -type d -exec chmod 777 {} \;
可解决Magento Connect Permissions的问题. 这样不太安全,你可以
Resetting File Permissions. cd find . -type f -exec chmod 644 {} \; find . -type d -exec chmod 755 {} \; chmod o+w var var/.htaccess app/etc chmod 550 pear chmod -R o+w media
