问题描述

版本:

操作系统 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文章.但是，我在从浏览器访问 phpmyadmin 时遇到 HTTP 500 错误.

并使用以下命令安装 phpmyadmin.

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

尝试过:

所以，我检查了错误日志 tail -f/var/log/apache2/error.log 并发现 Phpmyadmin 运行在折旧版本的 PHP 上.

运行以下命令sudo phpenmod mbstring

解决方案

重要提示:

如果您将 phpMyAdmin 公开或需要较新 phpMyAdmin 版本的功能，请更改版本号以获得更高的安全性.

这是从聊天中截取的.有些事情可能不准确，但这解决了 OP 的问题

使用以下教程安装 PHPMyAdmin:

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 &&解压 phpMyAdmin-5.1.0-rc1-all-languages.zip &&cd phpMyAdmin-5.1.0-rc1-all-languages

apt install pwgen -y

记下此命令的输出，我将其称为pw

pwgen -s 32 1

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

使用喜欢的编辑器编辑 config.inc.php，并将 pw 粘贴到这一行:

<预><代码>...$cfg['blowfish_secret'] = 'STRINGOFTHIRTYTWORANDOMCHARACTERS';/* 你必须填写这个以获得 cookie 身份验证！*/...

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

将以下内容粘贴到上一个命令中:

别名/phpmyadmin/path/to/that/phpMyAdmin-5.1.0-rc1-all-languages<目录"/path/to/that/phpMyAdmin-5.1.0-rc1-all-languages>选项 SymLinksIfOwnerMatch目录索引 index.php要求所有授予</目录>

使用:wq保存上一个，运行以下命令

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

将 your_password_here 替换为您自己的密码.

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

systemctl restart mysql

现在应该可以了.

附加说明:

要只允许您查看 phpMyAdmin，请尝试:

<目录/path/to/that/phpMyAdmin-5.1.0-rc1-all-languages">选项 SymLinksIfOwnerMatch目录索引 index.php需要本地# 或者改成# 需要 ip 127.0.0.1# 将 127.0.0.1 更改为您的个人电脑 IP 地址，# 不给服务器ip# 如果你想从公共服务器访问phpMyAdmin，但不允许其他人访问它</目录>

Version:

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

Problem:

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

And installed phpmyadmin using below command.

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

Tried :

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

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

解决方案

Important:

Please change the version number to get more security if you have phpMyAdmin exposed to the public or need features from newer phpMyAdmin versions.

This was taken from a chat. Some things might be inaccurate, but this solved the OP's problem

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

Make note of the output of this command, I will refer to it as pw

pwgen -s 32 1

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

Edit config.inc.php with favorite editor, and paste the pw in this line:

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

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

Paste the following to that previous command:

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>

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

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

Replace your_password_here to your own password.

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

systemctl restart mysql

It should work now.

Additional notes:

To only allow you to view phpMyAdmin, try:

<Directory "/path/to/that/phpMyAdmin-5.1.0-rc1-all-languages">
Options SymLinksIfOwnerMatch
DirectoryIndex index.php
Require local
# Or change it to
# Require ip 127.0.0.1
# change 127.0.0.1 to your personal computers ip address,
# not to the server ip
# if you want to access phpMyAdmin from a public server, but not allow others to access it
</Directory>
