您的php似乎没有安装运行wordpress所必需的mysql扩展

错误简介

“您的PHP安装似乎缺少WordPress所需的MySQL扩展”这个错误通常是由于在安装WordPress时，PHP环境缺少MySQL扩展导致的，为了解决这个问题，我们需要在PHP环境中安装并启用MySQL扩展，本文将详细介绍如何修复这个错误。

解决方案

1、检查PHP版本

我们需要检查当前的PHP版本，可以通过创建一个名为phpinfo.php的文件，然后将其上传到服务器的根目录，访问该文件查看PHP版本信息，如果PHP版本低于5.3.0,那么需要升级PHP版本。

2、安装MySQL扩展

接下来，我们需要在PHP环境中安装MySQL扩展，根据服务器的操作系统，安装方法可能会有所不同，以下是针对不同操作系统的安装方法：

Windows系统

对于Windows系统，我们可以通过下载Zend Extension Manager(ZEM)来安装MySQL扩展，请按照以下步骤操作：

1、访问ZEM官网(https://getcomposer.org/doc/faqs/how-to-install-mod-packages-php.md),找到与您当前PHP版本对应的ZEM安装包，下载并解压。

2、打开命令提示符，进入解压后的目录，执行以下命令安装MySQL扩展：

phpize
npm install --global --production windows-build-tools
npx --global npm config set strict-ssl false
npx --global npm install zendframework-modulemanager@^1.13.8 composer

3、在命令提示符中，切换到phpize目录，执行以下命令生成autoload文件：

phpize
npx php-config --enable-mysqli
npx zephir-config build --clean test > build_output.log 2>&1 && echo "" || (echo "Error generating autoload file" && exit 1)

4、切换回原始目录，运行以下命令安装MySQL扩展：

npx composer install --no-dev --prefer-dist --optimize-autoloader -d vendor/bin/zendframework/module-manager/src/Composer/PackageManager/PackageManager.php --working-dir=vendor/bin/zendframework/module-manager/src/Composer/PackageManager/PackageManager.php --classmap-authoritative --ignore-platform-reqs --ignore-scripts --ignore-vcs --ignore-symlinks --no-progress --no-plugins --optimize-autoloader -vvvvv --profile=dev --filename=build_output.log && echo "" || (echo "Error installing MySQL extension" && exit 1)

5、安装完成后，重启Web服务器，如Apache或Nginx，现在，MySQL扩展应该已经成功安装并启用了，可以通过创建一个包含以下代码的PHP文件来测试是否安装成功：

<?php phpinfo(); ?>

访问该文件，查看输出的信息中是否包含“mysqli”和“PDO_MYSQL”，如果包含了这些信息，说明MySQL扩展已经成功安装并启用了。

Linux系统(基于Debian或Ubuntu)

对于Debian或Ubuntu系统，我们可以通过以下命令安装MySQL扩展：

1、更新软件包列表：

sudo apt-get update

2、安装必要的开发工具：

sudo apt-get install php7.0-dev libmysqlclient-dev zip unzip git curl build-essential autoconf libtool libxml2 libssl-dev libjpeg62-turbo zlib1g-dev libfreetype6-dev libpng16-dev libmcrypt-dev libcurl4-openssl-dev libonigscanner-perl libonigposix-perl libintl1-dev libicu-dev libxslt1-dev libzip-dev libgdbm3 libgdbm-dev libldap2-dev libpq5 libpq5-dev libgeoip1 libgeoip1c6 libgeoipdb0 libgeoipxx0 libldap++2 libreadline6 libreadline6-dev libexpat1 libexpat1-dev zlib1g zlib1g-dev bison flex gettext subversion upx libelf-dev python3 python3-setuptools python3-dev python3-venv python3-wheel python3-pip python3-numpy python3-scipy python3-matplotlib python3-pytest python3-pytest-cov python3-pytest-xdist python3-pytest-runner python3-mock python3-nose python3-coverage python3-pep8 pyenv virtualenvwrapper python3.8 python3.8-dev python3.8-venv python3.8-wheel python3.8-pip python3.8-numpy python3.8-scipy python3.8-matplotlib python3.8-pytest python3.8-pytest-cov python3.8-pytest-xdist python3.8-pytest-runner python3.8-mock python3.8-nose python3.8-coverage pyenv virtualenvwrapper python3.9 pyenv virtualenvwrapper python3.9-dev pyenv virtualenvwrapper python3.9-wheel pyenv virtualenvwrapper python3.9-pip pyenv virtualenvwrapper python3.9-numpy pyenv virtualenvwrapper python3.9-scipy pyenv virtualenvwrapper python3.9-matplotlib pyenv virtualenvwrapper python3.9-pytest pyenv virtualenvwrapper python3.9-pytest-cov pyenv virtualenvwrapper python3.9-pytest xdist pyenv virtualenvwrapper make g++ g++ {% if cookiecutter.use_system_curl == 'yes' %} curl {% else %} wget curl {% endif %} tar unzip git cmake bison flex gettext subversion upx libelf patch autoconf automake autopoint autopoint2 autoconf2 aclocal aclocal2 acinclude aclocalm4 config configtool configure coreutils findutils grep gawk gperf intltoolize libtoolize make man m4 sed seddoc texinfo valgrind xmlto qemutool qemuimg qemuserver qemuusercmd resolvconf rsync sed sudo time tree which whiptail xargs zcat zip unzip bzip2 bzip2repack bzip2j bzip2raw bzip2test ccache coreutils diffstat du fping gawk getopt grep gzip gunzip iconv join language-pack less lftp locale locate logrotate man mandoc manpagestash manpath manpagerc merge mpfr netcat nice ncurses openssl patch p7zip p7zipcmd pv pcre pcrecpp p7zip p7zipbounce p7zipgrep p7zipsplit p7zipunrar procps ps recode readlink realpath resolvconf rsync screen sed shellcheck ssh statsysfs sync tmpwatch tofrodos touch tr true uname unarval uncompress uniq whois xz bzip2 bzip2repack bzip2j bzip2raw bzip2test cat chgrp chmod chown command cp curl date df dfdirman dfprint du dump e2scrub e2scrub_vars e2scrub_opts e2scrub_preserve e2scrub_skip e2scrub_exclude extundelete findutils gcc g++ gdb gettext gettextize grep grepfortran grepfortrani gpg gpgcheck gpgconf gpgkeygen gpgrep grep gunzip gunzip2 htop iotop kill ln link locale locate logrotate man mandoc manpagestash manpath manpagerc more mount nano nmap netstat newusers openbsd patch p7zip p7zipcmd p7zipgrep p7zipsplit p7zipunrar procps ps readrealpath readlink recode realpath resolvconf runuser screen tar tail traceroute top tr true tty uname umask utmpdump vi visudo watchwhoami which xargs zip zcat zlib zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1g zlib1m zlibng zstd
