shell-scripts通过yum搭建LAMP和mysql主从的相关文章

linux下Yum搭建lamp网站架构

在上节课我用了源代码和免安装软件的两种方式搭建了LAMP架构的网站,今天我们对上一节做个简单的总结: 源代码安装软件是我们Linux下常用的安装方法共分四个步骤: 在上一节我们的数据库就是免安装的.直接解压就可以使用了.是不是很简单,只要我们把前面的命令都掌握了,后面的服务搭建都不是问题. 今天我们讲解用yum搭建lamp网站架构.用yum命令安装软件也是我们Linux下一种常用的,因为他更简单,但是移植性差.好啦开始我们的操作了. 实验环境: 一台单机服务器,操作系统centos6.6.注意服

CentOS 查看操作系统版本 [[email protected] ~]# cat /etc/redhat-releaseCentOS release 6.6 (Final) 参考linux centos yum安装LAMP环境 Yum(全称为 Yellow dog Updater, Modified)是一个在Fedora和RedHat以及CentOS中的Shell前端软件包管理器. 基于RPM包管理,能够从指定的服务器自动下载RPM包并且安装,可以自动处理依赖性关系,并且一次安装所有依赖的软

Centos yum搭建lamp环境

首先安装Apache2 一条命令即可: yum -y install httpd 回车后,yum会提示当前已经安装的httpd版本,并自动更新:如果没有安装,则会自动安装.注意在yum安装过程中输入"Y"以确认安装. Apache安装完成后,手动启动Apache2: /etc/init.d/httpd start 这时,直接在 浏览器中输入服务器的IP地址,即可看到Apache2的默认页面.此时的Apache仅仅能提供HTTP服务,不能执行php.也不能连接MySQL 数据库. 安装M
