cp support-files/my-medium.cnf /usr/local/mysql/my.cnf
/usr/local/mysql/bin/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
??? 参数说明：MySQL 编译参数解析

??? PHP安装
修改为extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"
并在此行后增加以下几行，然后保存：
extension = "memcache.so"
extension = "pdo_mysql.so"
extension = "imagick.so"
再修改输出缓存output_buffering = Off
修改为output_buffering = On
并在文件最后添加以下配置信息： [eaccelerator]
zend_extension="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="64"

/usr/sbin/useradd -g www www

说明：创建虚拟主机目录。
rm -f /usr/local/php/etc/php-fpm.conf
rm -f /etc/sysctl.conf
cp php-fpm.conf /usr/local/php/etc/php-fpm.conf
说明：php-fpm是为PHP打的一个FastCGI管理补丁，可以平滑变更php.ini配置而无需重启php-cgi。
php-fpm.conf内容如下：（如果安装 Nginx + PHP 用于程序调试，将以下的<value name="display_errors">0</value>改为<value name="display_errors">1</value>，以便显示PHP错误信息，否则，Nginx 会报状态为500的空白错误页）

说明：使配置马上生效。
/etc/init.d/memcached -d -m 512 -u root -l 127.0.0.1 -p 11211
说明：-d选项是启动一个守护进程，-m是分配给memcache使用的内存数量，单位是MB,-u是运行Memcache的用户，-l是监听的服务器IP地址，-p是设置Memcache监听的端口，最好是1024以上的端口，-c选项是最大运行的并发连接数，默认是1024，按照服务器的负载量来设定。
ulimit -SHn 51200
说明：软硬限制，同一时间最多可开启的文件数。
