LAMP 是Linux Apache MySQL PHP的简写,其实就是把Apache, MySQL以及PHP安装在Linux系统上,组成一个环境来运行php的脚本语言。Apache是最常用的WEB服务软件,而MySQL是比较小型的数据库软件,下面我们就来构建这个LAMP环境。

这里安装完成了,如果要测试可以用以下方式
[root@server1 ~]# yun install -y httpd.x86_64
[root@server1 ~]# service httpd start
[root@server1 ~]# vim /var/www/html/index.php
浏览器输入ip看到php的欢迎页面即为成功,由于我后面要进行apache源码编译安装,这里不做测试了

以上实现的是LAP(Linux + Apache + PHP),下面我们将进行LAMP的架设
源码编译过程较长,写在一起略显臃肿,故单独拿出来了,请移步笔者的另一篇博客《MySQL5.7.17源码编译安装与配置 》(传送门:http://t.cn/R0VhqKq)
[root@server1 ~]# /etc/init.d/mysqld status
ERROR! MySQL is not running
[root@server1 ~]# /etc/init.d/mysqld start
Starting MySQL. SUCCESS!
[root@server1 ~]# netstat -tulnp | grep :3306 ##检查启动结果

mysqladmin -u root password ‘mypasswd’ ##修改密码(非必须,,这里只是方便你设置成自己容易记住的密码)
安装好MySQL,Apache及PHP后,为了可视化的管理MySQL数据库,我们可以安装phpMyAdmin。到其官网下载最新版本:https://www.phpmyadmin.net/
[root@server1 ~]# unzip phpMyAdmin-4.7.4-all-languages.zip
[root@server1 ~]# mv phpMyAdmin-4.7.4-all-languages/* /myapache/www/
[root@server1 phpmyadmin]# cp libraries/config.default.php config.inc.php
我们通过身份验证模式可以有两种配置方案,http和cookie身份验证模式。在这两种模式下,用户必须先在一个登录窗 口里输入MySQL数据库的有效用户名和密码,才能使用phpMyAdmin程序。这种做法有两个明显的好处;首先,因为MySQL数据库的密码没有出现在config.inc.php文件里,所以身份验证过程更加安全;其次,允许以不同的用户身份登录对自己的数据库进行管理。这两种身份验证模式尤其适合数据库中多个用户账号的情况。
第二种方案是,config身份验证模式。这种情况下,密码以明文形式保存在config.inc.php文件里。只需要把MySQL用户 名和密码直接写入到config.inc.php文件即可。这样,在登录phpMyAdmin时就不会提示输入用户名和密码了,而只直接用 config.inc.php文件里写入的用户登录 。如果只是在一个本地测试系统上使用phpMyAdmin,可以使用这种模式。
1)、http身份验证模式
如果想让phpMyAdmin使用HTTP身份验证模式,首先需要在config.inc.php文件做如下修改:
[root@server1 phpmyadmin]# vim config.inc.php
$cfg['Servers'][$i]['auth_type'] = 'http';
[root@server1 phpmyadmin]# /etc/init.d/apachectl restart
当完成设置之后,我们启动phpMyAdmin时,屏幕上将弹出一个WEB浏览器对话框,需要在这个对话框里输入MySQL用户名和密码,才能进入 phpMyAdmin操作界面。如下图示
登陆过程中可能会报错 #1130 - Host ‘server1’ is not allowed to connect to this MySQL server
如图
出现这种情况可能是你的帐号不允许从远程登陆,只能在localhost登陆。这个时候只要在mysqql的那台主机,登入mysql后,更改 “mysql” 数据库里的 “user” 表里的 “host” 项,从”localhost”改称”%”即可
[root@server1 ~]# mysql -uroot -pmypasswd
mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> select host, user from user; ##查看一下,果然如此
+-----------+-----------+
| host | user |
+-----------+-----------+
| localhost | mysql.sys |
| localhost | root |
+-----------+-----------+
2 rows in set (0.00 sec)
mysql> update user set host = '%' where user = 'root' and host='localhost'; ##修改登陆权限
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> select host, user from user;
+-----------+-----------+
| host | user |
+-----------+-----------+
| % | root |
| localhost | mysql.sys |
+-----------+-----------+
2 rows in set (0.00 sec)
mysql> exit
Bye
[root@server1 ~]# /etc/init.d/mysqld restart
再登陆就ok了
2)、cookie身份验证模式
cookie身份验证模式是HTTP身份验证模式的补充,不能使用HTTP身份验证模式的场合都可以使用它。cookie身份验证模式要求用户必须允许来自phpMyAdmin的cookie进入自己的计算机。即用户需要在浏览器中开启客户端的cookie功能。
如果想让phpMyAdmin使用cookie身份验证模式,除了必须修改config.inc.php文件里的auth_type语句外, 还必须向blowfish_secret参数提供一个字符串。这个字符串可以是任意的,目的是在把登录时使用的用户和密码存储在客户端电脑上的 cookie之前,系统将会使用这个字符串对它们进行加密。在config.inc.php中修改的内容如下:
[root@server1 phpmyadmin]# vim config.inc.php
$cfg['blowfish_secret'] = 'asdfghjkl';
$cfg['Servers'][$i]['auth_type'] = 'cookie';
[root@server1 phpmyadmin]# /etc/init.d/apachectl restart
3)、config身份验证模式
[root@server1 phpmyadmin]# vim config.inc.php
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = 'mypasswd';
[root@server1 phpmyadmin]# /etc/init.d/apachectl restart
