安装 MariaDB

MariaDB 是一个替换 MySQL 的产品。功能强大而可靠。安装前，如果您的服务器中安装有 MySQL ，那么您需要删除它。删除命令：

[root@server ~]# yum remove mysql* mysql-server mysql-devel mysql-libs

为了让 MariaDB 同时兼容 MySQL，我们需要安装 REMI 库来解决兼容性和安装 MariaDB 时软件包依赖性问题。安装命令：

[root@server ~]# rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

安装兼容 mysql55 包命令：

[root@server ~]# yum --enablerepo=remi-test --disablerepo=remi install compat-mysql55

为 MariaDB 创建一个 repository 文件，并在其中输入如下代码：

32 位系统：

[root@server ~]# vi /etc/yum.repos.d/mariadb.repo

MariaDB 5.5 CentOS repository list - created 2013-06-06 07:42 UTC

http://mariadb.org/mariadb/repositories/

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/5.5/centos6-x86
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

64 位系统：

[root@server ~]# vi /etc/yum.repos.d/mariadb.repo

MariaDB 5.5 CentOS repository list - created 2013-06-06 07:53 UTC

http://mariadb.org/mariadb/repositories/

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/5.5/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

保存并退出该文件，并运行 yum update 命令：

[root@server ~]# yum update

现在开始安装 MariaDB ：

[root@server ~]# yum install MariaDB-devel MariaDB-client MariaDB-server -y

安装完毕后，启动 MariaDB 服务，并让它在每次重启服务器后自动启动。

[root@server ~]# /etc/init.d/mysql start
Starting MySQL... SUCCESS!
[root@server ~]# chkconfig mysql on

为 MySQL 的 root 设置密码，默认情况下，MySWL root 密码是空的。为了防止未经授权的用户访问 MySQL 我们需要设置 root 用户密码：

[root@server ~]# /usr/bin/mysql_secure_installation
/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

You already have a root password set, so you can safely answer 'n'.

Change the root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n]
... Success!

Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n]
... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n]

Dropping test database...
ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist
... Failed! Not critical, keep moving...

Removing privileges on test database...
... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n]
... Success!

Cleaning up...

All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

安装 PHP

PHP（PHP 是：Hypertext Preprocessor 的缩写）是一种广泛使用的开放源码的通用脚本语言，适合于 Web 开发，可嵌入到 HTML 中。

安装 PHP 命令：

[root@server ~]# yum install php -y

创建一个的 “testphp.php” 的文件在 Apache 的文档根目录文件夹，在其中如入如下代码。命令：

[root@server ~]# vi /var/www/html/testphp.php
phpinfo();
?>

重新启动 httpd 服务：

[root@server ~]# /etc/init.d/httpd restart

用浏览器打开 http://server-ip-address/testphp.php 。它会显示关于 PHP 的详细信息，比如版本，建立日期等。

如果您需要安装所有的 PHP 模块，可以输入 *yum install php -y** 来安装，安装完毕后重启 httpd 服务。重启服务后，您可以用浏览器打开 http://server-ip-address/testphp.php 来查看您刚才安装的模块情况。

安装 nstall phpMyAdmi

根据您的情况来选择是否安装 nstall phpMyAdmin 。

phpMyAdmin 是一个免费开源的 MySQL 管理工具。默认情况下 CentOS/RHEL/Scientific Linux 官方库中没有 phpMyAdmin。所以我们需要从 EPEL 库中安装。

首先，我们需要添加 EPEL 库：

[root@server ~]# rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

现在我们可以安装 phpMyAdmin 了。安装命令：

[root@server ~]# yum install phpmyadmin -y

安装完毕后，我们需要配置的 phpMyAdmin。打开 phpmyadmin.conf 的文件。查找以“<Directory” 开头到包含的部分，如下命令所示：

[root@server ~]# vi /etc/httpd/conf.d/phpMyAdmin.conf

Alias /phpMyAdmin /usr/share/phpMyAdmin
Alias /phpmyadmin /usr/share/phpMyAdmin

Comment the following Section

Apache 2.4

Require ip 127.0.0.1

Require ip ::1

Apache 2.2

Order Deny,Allow

Deny from All

Allow from 127.0.0.1

Allow from ::1

#

打开 config.inc.php 文件，将 cookie 改为 http。

[root@server ~]# cp /usr/share/phpMyAdmin/config.sample.inc.php /usr/share/phpMyAdmin/config.inc.php
[root@server ~]# vi /usr/share/phpMyAdmin/config.inc.php
[...]
/ Authentication type /
$cfg['Servers'][$i]['auth_type'] = 'http';
[...]

重新启动 Apache 服务：
