问题描述：

版本:

OS lsb_release -a :Ubuntu 18.04.5 LTS

OS lsb_release -a : Ubuntu 18.04.5 LTS
PHP php -v : 8.0.1
Apache apache2 -v : 2.4.29 (Ubuntu)
MySQL mysql --version : mysql Ver 14.14 Distrib 5.7.32

问题:

我正在尝试使用以下

I'm trying to install LAMP Stack using following article. However, I was getting HTTP 500 Error while accessing phpmyadmin from browser.

并使用以下命令安装了phpmyadmin.

And installed phpmyadmin using below command.

sudo apt install phpmyadmin php-mbstring php-zip php-gd php-json php-curl

尝试过:

因此，我检查了错误日志 tail -f/var/log/apache2/error.log ，发现Phpmyadmin在PHP的贬值版本上运行.

So, I checked with Error Log tail -f /var/log/apache2/error.log and found that Phpmyadmin was running on depreciated version of PHP.

我通过用 []

{}

数组和字符串偏移量访问语法错误

运行以下命令 sudo phpenmod mbstring

I'd solved Array and string offset access syntax error by removing { } with [ ]
Run the following command sudo phpenmod mbstring

使用以下教程安装PHPMyAdmin:

Install PHPMyAdmin using the following tutorial:

apt purge phpmyadmin -y

cd /path/to/somefolder

wget https://files.phpmyadmin.net/phpMyAdmin/5.1.0-rc1/phpMyAdmin-5.1.0-rc1-all-languages.zip && unzip phpMyAdmin-5.1.0-rc1-all-languages.zip && 
cd phpMyAdmin-5.1.0-rc1-all-languages

apt install pwgen -y

记下该命令的输出，我将其称为 pw

pwgen -s 32 1

cp config.sample.inc.php config.inc.php

使用收藏夹编辑器编辑config.inc.php，并在此行中粘贴 pw :

. . .
$cfg['blowfish_secret'] = 'STRINGOFTHIRTYTWORANDOMCHARACTERS'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */
. . .

vim /etc/apache2/conf-available/phpmyadmin-custom.conf

将以下内容粘贴到先前的命令中:

Alias /phpmyadmin /path/to/that/phpMyAdmin-5.1.0-rc1-all-languages
<Directory "/path/to/that/phpMyAdmin-5.1.0-rc1-all-languages">
Options SymLinksIfOwnerMatch
DirectoryIndex index.php
Require all granted
</Directory>

使用:wq 保存上一个，运行以下命令

Save the previous one using :wq, Run the following command

a2enconf phpmyadmin-custom && systemctl restart apache2 && mysql

将您的密码_此处替换为您自己的密码.

Replace your_password_here to your own password.

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your_password_here';

systemctl restart mysql

现在应该可以正常工作了.

It should work now.
