ami ec2 quick LAMP install

This is what I run when I want to quickly create an AWS instance running apache, mysql and php:
yum install -y php-mysql php-xml php-mcrypt php-mbstring php-gd yum install -y php-pear yum install -y mysql-server yum install -y php-devel yum install php-pecl-apc yum install -y php-pear php-devel httpd-devel chkconfig --levels 235 httpd on chkconfig --levels 235 mysqld on service mysqld start service httpd start echo max_allowed_packet=16M>>/etc/my.cnf echo delayed_insert_timeout=10000>>/etc/my.cnf echo connect_timeout=100000>>/etc/my.cnf
Note: if you need pretty url, make sure that mod_rewrite is enabled (Enabled by default on centos and Ubuntu: a2enmod mod_rewrite). Then make sure the httpd config /etc/httpd/conf/httpd.conf allows overrides AllowOverride all) Then, if I need drush, I install it with the following 2 lines:

pear channel-discover pear install drush/drush
