centos 升级phpmyadmin？centos6升级centos7
其实centos 升级phpmyadmin的问题并不复杂，但是又很多的朋友都不太了解centos6升级centos7，因此呢，今天小编就来为大家分享centos 升级phpmyadmin的一些知识，希望可以帮助到大家，下面我们一起来看看这个问题的分析吧！
阿里云上的centos 7.2怎么yum安装php 5.6
因之前通过网易的 centos镜像，将阿里云的 centos升级到最新版了，乘自己的项目尚未开始正式开发，遂将所有的相应环境都升级到最高。
查看 centos版本：
[root@iZ23d~]# cat/etc/centos-release
CentOS Linux release 7.2.1511(Core)
1、删除之前的 php版本：
[root@iZ23d~]# yum remove php* php-common
Loaded plugins: langpacks
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration
Repository centosplus is listed more than once in the configuration
No Match for argument: php-5.4.16
No Match for argument: php-5.4.16.tar.gz
No Match for argument: php-7.0.1RC1
No Match for argument: php-7.0.1RC1.tar.gz
No Match for argument: phpMyAdmin-4.4.0.tar.gz
No Match for argument: php-common
No Packages marked for removal
2、rpm安装 Php7相应的 yum源：
[root@iZ23d~]# rpm-Uvh

3、直接yum安装php7：
[root@iZ23d~]# yum install php70w
Loaded plugins: langpacks
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration

4、检查 php版本：
[root@iZ23d~]# php-v

[root@iZ23d2e6hoqZ~]#
以上显示安装成功！
5、重启 Apache，查看 phpinfo:
[root@iZ23d~]# systemctl restart httpd.service
检查phpinfo:

以上显示 php7安装成功！
如何在CentOS上安装phpMyAdmin
在CentOS上安装phpMyAdmin，你第一步需要架设一台Web服务器(如Apache或nginx)，安装好MySQL/MariaDB数据库和PHP。根据你的偏好和需求，你可以从LAMP和LEMP中选择一种安装。
另一个要求是允许在你的CentOS上安装EPEL库。
在CentOS6或7上安装phpMyAdmin
一旦你设置了EPEL库，你就能轻松地用以下命令安装phpMyAdmin了。
在CentOS 7上:
$ sudo yum install phpmyadmin
在CentOS 7上:
$ sudo yum install phpmyadmin php-mcrypt
在CentOS 7上配置phpMyAdmin
默认情况下，CentOS 7上的phpMyAdmin只允许从回环地址(127.0.0.1)访问。为了能远程连接，你需要改动它的配置。
用文本编辑器打开phpMyAdmin的配置文件(路径：/etc/httpd/conf.d/phpMyAdmin.conf)，找出并注释掉带有"Require ip XXXX"字样的代码行。会有四处这样的代码行，用"Require all granted"取而代之。重新改动过的配置文件如下所示。
$ sudo vi/etc/httpd/conf.d/phpMyAdmin.conf
.....<Directory/usr/share/phpMyAdmin/> AddDefaultCharset UTF-8<IfModule mod_authz_core.c># Apache 2.4<RequireAny>#Require ip 127.0.0.1#Require ip::1 Require all granted</RequireAny></IfModule><IfModule!mod_authz_core.c># Apache 2.2 Order Deny,Allow Deny from All Allow from 127.0.0.1 Allow from::1</IfModule></Directory><Directory/usr/share/phpMyAdmin/setup/><IfModule mod_authz_core.c># Apache 2.4<RequireAny>#Require ip 127.0.0.1#Require ip::1 Require all granted</RequireAny></IfModule><IfModule!mod_authz_core.c># Apache 2.2 Order Deny,Allow Deny from All Allow from 127.0.0.1 Allow from::1</IfModule></Directory>.....
最后，重启httpd使改动生效。
$ sudo systemctl restart httpd
在CentOS 6上配置phpMyAdmin
默认情况下，CentOS 6上的phpMyAdmin是禁止从每个IP地址访问的。为了能远程连接，你需要改动它的配置。
用文本编辑器打开phpMyAdmin的配置文件(路径：/etc/httpd/conf.d/phpMyAdmin.conf)，找出并注释掉"Deny from all"字样的代码行。然后把"Allow from 127.0.0.1"字样的代码行改成"Allow from 0.0.0.0"。重新改动过的配置文件如下所示。
$ sudo vi/etc/httpd/conf.d/phpmyadmin.conf
<Directory"/usr/share/phpmyadmin"> Order Deny,Allow# Deny from all Allow from 0.0.0.0</Directory>
下一步是将phpMyAdmin的配置文件用blowfish加密工具加密。这一步需要加密cookie里的密码来作为基于cookie的部分认证。
用文本编辑器打开如下路径所示的文件并且用blowfish设置一个随机密码，如下所示。
$ sudo vi/usr/share/phpmyadmin/config.inc.php
$cfg['blowfish_secret']='kd5G}d33aXDc50!';/* YOU MUST FILL IN THIS FOR COOKIE AUTH!*/
最后，重启httpd使改动生效。
$ sudo service httpd restart
测试phpMyAdmin
测试phpMyAdmin是否设置成功，访问这个页面：
你应该能通过Web界面来记录下任何MySQL用户(比如root)和管理MySQL/MariaDB的数据库/表。
疑难解答
这里有一些在CentOS上安装phpMyAdmin的过程中遇到的一些问题解决方法。
当你在浏览器里尝试连接phpMyAdmin页面的时候，你看到"403 Forbidding"错误：
You don't have permission to access/phpMyAdmin on this server.
发生这种错误是因为phpMyAdmin默认阻止了IP地址远程连接。要修复这种错误，你需要编辑它的配置文件来允许远程连接。具体操作见上。
当你连接phpMyAdmin页面时，你看见"The configuration file now needs a secret passphrase(blowfish_secret)."信息，并且你无法登录。
要修复这种错误，你需要编辑/usr/share/phpmyadmin/config.inc.php这个文件来添加一个随机的blowfish密码，然后重启httpd，如下所示。
$ sudo service httpd restart(CentOS 6)
$ sudo systemctl restart httpd(CentOS 7)
$cfg['blowfish_secret']='kd5G}d33aXDc50!';/* YOU MUST FILL IN THIS FOR COOKIE AUTH!*/
当你连接phpMyAdmin页面时，你看见"Cannot load mcrypt extension. Please check your PHP configuration"错误信息。
要修复这种错误，要安装下面这个包：
然后重启httpd：
$ sudo service httpd restart(CentOS 6)
$ sudo systemctl restart httpd(CentOS 7)
$ sudo yum install php-mcrypt
