LAMP(Linux-Apache-MySQL-PHP)网站架构是目前国际流行的Web框架,该框架包括:Linux操作系统,Apache网络服务器,MySQL数据库,Perl、PHP或者Python编程语言,所有组成产品均是开源软件,是国际上成熟的架构框架,很多流行的商业应用都是采取这个架构,和Java/J2EE架构相比,LAMP具有Web资源丰富、轻量、快速开发等特点,微软的.NET架构相比,LAMP具有通用、跨平台、高性能、低价格的优势,因此LAMP无论是性能、质量还是价格都是企业搭建网站的首选平台。

下面我们便开始lamp环境的搭建,及lamp的应用。
为方便我们后续软件包的安装,
配置本地yum:
[root@localhost ~]# vim /etc/yum.repos.d/rhel-debuginfo.repo
[rhel-server]
name=Red Hat Enterprise Linux server
baseurl=file:///mnt/cdrom/Server
enabled=1
gpgcheck=1
gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-redhat-release
yum配置完成,开始lamp环境搭建:
查看相关的软件包:
[root@localhost ~]# yum list all |grep -E "httpd|mysql|php"
然后来安装我们所需的软件包:
[root@localhost ~]# yum install httpd mysql mysql-server php php-mysql php-gd php-mbstring php-xml
接下来便要开启相关服务:
[root@localhost ~]# service httpd start
启动 httpd:                                               [确定]
[root@localhost ~]# service mysqld start
设置开机启动:
[root@localhost ~]# chkconfig httpd on
[root@localhost ~]# chkconfig mysqld on
[root@localhost ~]#
同时还可以查看我们的mysql服务的端口:
[root@localhost ~]# netstat -tupln |grep mysqld
我们可以尝试进入数据库,初始默认root,密码为空。
[root@localhost ~]# mysql

mysql> \q;                                              //退出数据库操作界面
Bye
[root@localhost ~]#
为我们的root账号配置密码:
[root@localhost ~]# mysqladmin -u root -p password '123'         配置新密码为 123
Enter password:                注意:此处要输入的是旧密码,为空,我们直接回车即可。
[root@localhost ~]#
然后便可以在进入试试,看看密码是否已经生效:
[root@localhost ~]# mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 4
Server version: 5.0.77 Source distribution
 
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
 
mysql>
如图示,密码已经生效。
然后,进入/var/www/html目录下,编辑index.php文件
[root@localhost html]# vim index.php
<?php
phpinfo();
?>
~   
然后我们便在宿主机上看看能不能访问到这个页面:
在宿主机浏览器或运行里输入虚拟机的ip:
如上图,我们已经能够查看php的相关信息了。
接下来进行进一步的测试:
重新编辑我们的index.php文件:
[root@localhost html]# vim index.php
<?php
$link=mysql_connect('127.0.0.1','root','123');
if($link)
echo "ok";
else
echo "not";
?>
   
然后再进行上面的操作,在宿主机上:
如上图所示,成功访问。
当我们关闭mysqld服务时,就不能访问了。如下图:
我们这部分的测试已经结束了,接下来安装phpmyadmin(注意版本匹配问题),图形化管理。
如下图所示,我们的root/目录下已经有了相关软件包:
解压缩:
拆解到当前目录,然后移动到/var/www/html/phpmyadmin
[root@localhost ~]# unzip phpMyAdmin-2.11.10.1-all-languages.zip
[root@localhost ~]# mv phpMyAdmin-2.11.10.1-all-languages /var/www/html/phpmyadmin
[root@localhost ~]#
 
 
在我们的浏览器里访问http://192.168.44.127/phpmyadmin
出现了如下页面:                                   

 

解决上面问题的办法:
先拷贝我们的阳样例文件,命名为config.inc.php,然后修改config.inc.php文件
[root@localhost phpmyadmin]# cp -p config.sample.inc.php config.inc.php
修改第十七行,引号之间的内容可以随便填:

 

 

保存退出后,
重启我们的apache服务:
[root@localhost phpmyadmin]# service httpd restart
停止 httpd:                                               [确定]
启动 httpd:                                               [确定]
[root@localhost phpmyadmin]#
刷新我们刚才的页面,便么有问题了。(如果不行,请清理浏览器的缓存)

 

 

 

可以发现页面下方还报有一个小错误,无法载入mcrypt扩展。
那么我们便要安装mcrypt安装包
[root@localhost ~]# rpm -ivh libmcrypt-2.5.7-5.el5.i386.rpm    //该包为关联包
warning: libmcrypt-2.5.7-5.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 217521f6
Preparing...                ########################################### [100%]
   1:libmcrypt              ########################################### [100%]
[root@localhost ~]# rpm -ivh php-mcrypt-5.1.6-5.el5.i386.rpm
warning: php-mcrypt-5.1.6-5.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 217521f6
Preparing...                ########################################### [100%]
   1:php-mcrypt             ########################################### [100%]
[root@localhost ~]#
然后我们再去刷新之前的页面,便可以发现没有问题了:

 

 

然后我们登录进去,root用户,密码123.

 

 

 

进入图形化管理界面,我们可以随意创建一个数据库,假设我们创建一个论坛的数据库discuz。

 

如图示,我们已经成功创建discuz数据库。

搭建好lamp环境之后,我们便可以进入实际应用过程了:
假设我们搭建一个论坛,
请自行到discuz官网下载最新压缩包,
在我们的root目录下已经有Discuz_X2.5_SC_GBK.zip了:

(我们在此处使用的是discuz,同样流行的还有phpwind以及国外的wordpress,使用方法大同小异)

 

解压缩到/var/www/html/mybbs目录下
[root@localhost ~]# unzip Discuz_X2.5_SC_GBK.zip -d /var/www/html/mybbs
进入/var/www/html/mybbs目录下查看

 

 

然后我们可以试图直接访问index.php页面:

 

 

 

如上图所示,能成功访问,但是因为编码格式,会出现乱码问题。
我们需要修改etc/httpd/conf目录下的httpd.conf文件
将UTF-8字符集禁掉(可以在滴行命令模式下搜索UTF:”:/UTF”)
然后重启apache服务:
[root@localhost upload]# vim /etc/httpd/conf/httpd.conf

 

 

 

[root@localhost upload]# service httpd restart
停止 httpd:                                               [确定]
启动 httpd:                                               [确定]
[root@localhost upload]#
然后我们重新访问,便不会出现编码问题了:

 

 

进入安装向导,可以看到很详细的安装步骤。
但是因为权限问题,会出现如下提示:

 

 

那么我们便去修改相关目录的权限:
[root@localhost upload]# chmod -R o+w data       //-R参数为递归修改
[root@localhost upload]# chmod -R o+w config
[root@localhost upload]# chmod -R o+w uc_client/
[root@localhost upload]# chmod -R o+w uc_server/
[root@localhost upload]#

 

 

然后刷新我们的页面,便可以正常进行了:

 

 

成功安装后,我们可以进入mysql查看一下:
[root@localhost upload]# mysql -u root -p
Enter password:

没有问题,那么接下来我们试试看 可不可以访问了:

 

 

 

如上图所示,成功访问。
我们以管理员身份登录,便可以在该页面对搭建的论坛进行操作了。

 

至于discuz的使用,编者就不在此赘述了,读者可以自行摸索。
