注意：如何windows的文件传送到centos上呢？
可以通过xshell来连接到远程的终端，然后在centos终端yum 编译安装
安装命令：
yum install lrzsz
从服务端发送文件到客户端：
sz filename
从客户端上传文件到服务端：
rz
在弹出的框中选择文件，上传文件的用户和组是当前登录的用户
SecureCRT设置默认路径：
Options -> Session Options -> Terminal -> Xmodem/Zmodem ->Directories
Xshell设置默认路径：
右键会话 -> 属性 -> ZMODEM -> 接收文件夹
测试：
开发板接收文件：
1. 进入开发板要接收文件的目录
2. 开发板执行命令# rz
3. 在minicom下，按住Ctrl+A键不放，按下Z键
4. 按下S键选择发送文件
5. 选择zmodem，用回车键确认
6. 用空格选择主机要发送的文件，用回车键确认
7. 传输完成后按任意键返回
开发板发送文件：
1. 进入开发板要发送文件的目录
2. 进入主机要接收文件的目录
2. 主机执行命令# rz
3. 开发板执行命令# sz filename
PS：同事和我说SecureCRT可以方便的上传下载文件，而Xshell没有。我上网一查原来用的是同一个sz/rz工具，Xshell下没有菜单选择要输命令。
以上rz 和 sz就可以用了
今天用yum方法搭建起了个LAMP环境，中间遇到了很多问题，经过google和各位前辈的帮助，终于将环境搭建起来，现在把完整的步骤记录下来，
1. 换源，sohu的相当好用。
1.1备份CentOS-Base.repo
cd /etc/yum.repos.d/
cp CentOS-Base.repo CentOS-Base.repo.bak
1.2替换源
用vi打开CentOS-Base.repo，并将内容清空，然后将下面的内容复制进去，并保存。
# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#

1.3更新一下。
yum -y update

cd /etc/yum.repos.d/

1.3更新一下。
yum -y update
1、注意安装lamp前 进行旧版本自带lamp的检测如果有安装，须先卸载
如卸载httpd 出现失败，因为 httpd有占用 关联，需要解除关联如下
centos删除
系统自带的httpd
1、[root@localhost etc]# rpm -qa|grep httpd，查看与httpd相关软件包。
httpd-tools-2.2.15-15.el6.centos.i686
httpd-2.2.15-15.el6.centos.i686
www.2cto.com
2、然后删除httpd：
[root@localhost etc]# rpm -e httpd
出现问题：
error: Failed dependencies:
httpd >= 2.2.0 is needed by (installed) gnome-user-share-0.10-6.el5.i386
3、还有一个相关的软件包没有删除，清除之，即：
[root@localhost etc]# rpm -e gnome-user-share
www.2cto.com
4、再删除httpd
[root@localhost etc]# rpm -e httpd
2. 用yum安装Apache,Mysql,PHP.
2.1安装Apache
yum install httpd httpd-devel
安装完成后，用/etc/init.d/httpd start 启动apache
设为开机启动:chkconfig httpd on
2.2 安装mysql
2.2.1 yum install mysql mysql-server mysql-devel
同样，完成后，用/etc/init.d/mysqld start 启动mysql
2.2.2 设置mysql密码
mysql>; USE mysql;
mysql>; UPDATE user SET Password=PASSWORD('newpassword') WHERE user='root';
mysql>; FLUSH PRIVILEGES;
2.2.3 允许远程登录
mysql -u root -p
Enter Password: <your new password>
mysql>GRANT ALL PRIVILEGES ON *.* TO '用户名'@'%' IDENTIFIED BY '密码' WITH GRANT OPTION;
完成后就能用mysql-front远程管理mysql了。
2.2.4 设为开机启动
chkconfig mysqld on
3. 安装php
yum install php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml
/etc/init.d/httpd restart
4. httpd中配置 解析php脚本
配置httpd.conf文件（/etc/httpd/conf/httpd.conf）
添加LoadModule php5_module modules/libphp5.so
找到AddType application/x-gzip .gz .tgz，在后面添加
AddType application/x-httpd-php .php
AddType application/x-httpd-php .html
5. 测试一下
4.1在/var/www/html/新建个test.php文件，将以下内容写入，然后保存。
<?
phpinfo();
?>
4.2 防火墙配置
a.添加.允许访问端口{21: ftp, 80: http}.
iptables -I RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 21 -j ACCEPT
iptables -I RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT
b.关闭防火墙{不推荐}.
service iptables stop
c.重置加载防火墙
service iptables restart
4.3然后在客户端浏览器里打开http://serverip/test.php，若能成功显示，则表示安装成功。
至此，安装完毕。感慨，yum真是太好用了。
添加LoadModule php5_module modules/libphp5.so
