网络配置
Netconfig 图形界面设置网络，重启network后生效。
网络服务启动脚本
/etc/init.d/network 从新启动才能生效
扩展：# /etc/rc.d/init.d/network start 启动network
# /etc/rc.d/init.d/network stop 停止network
# /etc/rc.d/init.d/network restart 重启network

# ifconfig eth0 down 停止eth0接口
# ifconfig eth0 up 开启eth0接口

Ifdown 网络接口名称停止某个网络接口。
Ifup 网络接口名称开启某个网络接口。

设置Ip
netcofnig
/etc/rc.d/init.d/network start
ifconfig eth0 up

设置防火墙
vi /etc/sysconfig/iptables
重启防火墙
/etc/init.d/iptables restart
查看防火墙
/etc/init.d/iptables status

创建目录
Mkdir /home/soft/

安装Mysql5.0.37

开始安装和编译代码：
groupadd mysql
useradd -g mysql mysql
tar zxvf mysql-5.0.37.tar.gz
cd mysql-5.0.37
./configure --prefix=/usr/local/webserver/mysql
make
make install
scripts/mysql_install_db
chown -R root:mysql /usr/local/webserver/mysql
chown -R mysql:mysql /usr/local/webserver/mysql/var
chgrp -R mysql /usr/local/webserver/mysql
cp support-files/my-medium.cnf /etc/my.cnf
cp /usr/local/webserver/mysql/share/mysql/mysql.server /usr/local/webserver/mysql/share/mysql/mysqld
chmod a+x /usr/local/webserver/mysql/share/mysql/mysqld
mysqladmin -uroot password "321321"
启动服务方法
/usr/local/webserver/mysql/share/mysql/mysqld start
停止服务方法
/usr/local/webserver/mysql/bin/mysqladmin shutdown

cp /usr/local/webserver/mysql/include/mysql/mysql.h /usr/local/webserver/mysql/

设置成开机自启动
在/etc/rc.d/rc.local文件中加入一行
/usr/local/webserver/mysql/share/mysql/mysqld start
这样每次重新启动系统以后,mysql也会随系统一起启动.

cd memcache-2.2.5/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../

tar jxvf eaccelerator-0.9.5.3.tar.bz2

make
make install
cd ../

配置eAccelerator加速PHP
mkdir -p /usr/local/webserver/eaccelerator_cache

修改PHP.ini
vi /usr/local/webserver/php/etc/php.ini

手工修改：查找/usr/local/webserver/php/etc/php.ini中的extension_dir = "./"
　　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"

　　再查找output_buffering = Off
　　修改为output_buffering = On
按shift+g键跳到配置文件的最末尾，加上以下配置信息：
[eaccelerator]
zend_extension="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="128"
eaccelerator.cache_dir="/usr/local/webserver/eaccelerator_cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="300"
eaccelerator.shm_prune_period="120"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"

修改配置文件
vi /etc/sysctl.conf
输入以下内容
kernel.shmmax = 134217728
然后执行以下命令使配置生效
/sbin/sysctl -p

创建www用户和组，虚拟主机使用的目录：
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
mkdir -p /data0/htdocs/www
chmod +w /data0/htdocs/www
chown -R www:www /data0/htdocs/www

创建php-fpm配置文件（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）：
在/usr/local/webserver/php/etc/目录中创建php-fpm.conf文件：

rm -f /usr/local/webserver/php/etc/php-fpm.conf
vi /usr/local/webserver/php/etc/php-fpm.conf

输入以下内容（如果您安装 Nginx + PHP 用于程序调试，请将以下的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）：
