CentOS 5.5使用yum来安装LAMP(php运行环境)

时间:2022-05-05 15:08:20
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. 


[base] 
name=CentOS-$releasever - Base 
baseurl=http://mirrors.sohu.com/centos/$releasever/os/$basearch/ 
gpgcheck=1 
gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5 
#released updates 
[updates] 
name=CentOS-$releasever - Updates 
baseurl=http://mirrors.sohu.com/centos/$releasever/updates/$basearch/ 
gpgcheck=1 
gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5 
#packages used/produced in the build but not released 
[addons] 
name=CentOS-$releasever - Addons 
baseurl=http://mirrors.sohu.com/centos/$releasever/addons/$basearch/ 
gpgcheck=1 
gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5 
#additional packages that may be useful 
[extras] 
name=CentOS-$releasever - Extras 
baseurl=http://mirrors.sohu.com/centos/$releasever/extras/$basearch/ 
gpgcheck=1 
gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5 
#additional packages that extend functionality of existing packages 
[centosplus] 
name=CentOS-$releasever - Plus 
baseurl=http://mirrors.sohu.com/centos/$releasever/centosplus/$basearch/ 
gpgcheck=1 
enabled=0 
gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5 
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。
