牛刀小试，Linux实践能力测试终极脚本
牛刀小试，Linux实践能力测试终极脚本
测试说明：本测试重点考察在linux环境下搭建LAMP虚拟主机环境配置和调试排错的能力。请按任务要求在虚拟机上完成操做任务，并在实验报告上记录主要操做步骤和配置文件中编辑的内容。测试环境为虚拟机centos6.6，测试时间为100分钟。
所需软件包能够从ftp://172.18.74.252下载，yum源为ftp://172.18.74.252/centos6.6php
注意：为方便测试关闭防火墙（#services iptables stop），关闭SElonux（# setenforce 0）html
任务1：配置虚拟机网络地址，使之与主机互相ping通。 （20分）mysql
要求：设置虚拟机网卡为NAT模式，启动登陆虚拟机，配置其网卡地址为静态地址，与虚拟机vmnet8在同一网段，最后三位数为“学号后三位mod254”，虚拟机主机名为姓名全拼。linux
检查点：虚拟机与主机可以互相ping通，虚拟机可以访问互联网。web
提示：编辑/etc/sysconfig/network-scripts/ifcfg-eth*文件，/etc/sysconfig/network文件，重启network服务；或者直接使用ifconfig命令修改IP地址。sql
任务2：安装bind软件包，使之可以提供域名解析服务。 （20分）shell
要求：使用yum方式安装bind软件包，设立“姓名全拼.com”和“学号.com”两个正向区域，并分别设置www主机A记录地址为虚拟机地址。数据库
检查点：主机ping“www.[姓名全拼].com”和“www.[学号].com”能够与虚拟主机通讯。apache
提示：编辑/etc/named.conf文件和/var/named/区域数据文件，使用named-checkconf和named-checkzone进行检查，改变区域数据文件所属组，重启named服务或rndc reload。注意检查主机dns服务器配置为虚拟机地址。vim
任务3：安装apache软件，配置基于名字的虚拟主机。 （20分）
要求：使用源码方式安装apache，配置两个基于名字的虚拟主机，“www.[姓名全拼].com”和“www.[学号].com”，虚拟主机目录在/var/wwwroot下，目录名为域名。
检查点：从主机访问“www.[姓名全拼].com”和“www.[学号].com”站点的默认主页能够分别看到“this’s 姓名 site”和“this’s 学号 site”。
提示：编辑/usr/local/apache/conf/httpd.conf文件配置虚拟主机，注意配置虚拟主机目录的访问权限；在/var/wwwroot创建虚拟主机目录，编辑index.html文件。
任务4：安装mysql，建立数据库和数据表并输入数据。 （10分）
要求：使用yum方式安装mysql-server，改变root用户登陆密码为123456，建立数据库project。
/* 建立表 */
create table news (
id int unsigned auto_increment primary key,
title varchar(60) not null,
content text not null,
addtime timestamp default current_timestamp not null
);
/*插入测试数据*/
insert into news (title, content)
values('新闻标题1', '新闻内容1'),
('新闻标题2','新闻内容2');
检查点：select * from news;显示所有记录，注意mysql数据库的编码格式。
提示：改密码 #mysqladmin –u root –p password 新密码字符
任务5：安装PHP环境，编写运行php脚本。 （10分）
要求：使用yum方式安装PHP，编辑index.php文件放到“学号”虚拟主机，使之可以链接mysql数据库，读取显示数据表的内容。
检查点：在主机浏览器访问http://www.[学号].com/index.php,显示数据表news的内容。
提示：拷贝libphp 5.so，安装php_mysql软件包，编辑httpd.conf，注意要重启apache
任务6：安装vsftp软件包，配置虚拟主机的ftp环境。 （10分）
要求：使用yum方式安装vsftpd。创建用户“姓名全拼”和“学号”，设定用户主目录为/var/wwwroot/[姓名全拼].com和/var/wwwroot/[学号].com，密码都为123。
检查点：从主机能够访问ftp站点，并上传网站内容。
任务7：使用ab性能测试软件，优化虚拟主机性能。 （10分）
要求：使用apache自带的ab软件测试虚拟主机性能，并记录最优结果。
提示：/usr/local/apache/bin/ab –c [并发数] –n [访问次数] http://www.[学号].com/index.php
