1. 第一步安装 mysql 这个必须是第一步

sudo apt install mysql-server

2. 第二步修改mysql密码 ubuntu 首次登录mysql8 未设置密码或忘记密码解决方法 亲测可用

3. 第三步安装 nginx

sudo apt update && sudo apt upgrade -y
sudo apt install nginx
sudo systemctl enable nginx
sudo systemctl start nginx
sudo systemctl status nginx
sudo ufw allow http
sudo chown www-data:www-data /usr/share/nginx/html -R

第 4 步：安装 PHP

sudo apt install php8.1 php8.1-fpm php8.1-mysql php8.1-cli php8.1-common php-json  php8.1-readline php8.1-mbstring php8.1-xml php8.1-gd php8.1-curl
sudo systemctl start php8.1-fpm
sudo systemctl enable php8.1-fpm
sudo systemctl status php8.1-fpm

第 5 步：创建 Nginx 服务器块

sudo rm /etc/nginx/sites-enabled/default
sudo vim /etc/nginx/conf.d/default.conf

server {listen 80;listen [::]:80;server_name _;root /usr/share/nginx/html/;index index.php index.html index.htm index.nginx-debian.html;location / {try_files $uri $uri/ /index.php;}location ~ \.php$ {fastcgi_pass unix:/run/php/php7.4-fpm.sock;fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;include fastcgi_params;include snippets/fastcgi-php.conf;}# A long browser cache lifetime can speed up repeat visits to your pagelocation ~* \.(jpg|jpeg|gif|png|webp|svg|woff|woff2|ttf|css|js|ico|xml)$ {access_log        off;log_not_found     off;expires           360d;}# disable access to hidden fileslocation ~ /\.ht {access_log off;log_not_found off;deny all;}
}

将以下文本粘贴到文件中。以下代码片段将使 Nginx 监听 IPv4 端口 80 和 IPv6 端口 80，并使用 catch-all 服务器名称。

sudo nginx -t
sudo systemctl reload nginx

第 6 步：安装 WordPress

sudo apt update && sudo apt upgrade
wget https://wordpress.org/latest.zip sudo apt install unzip
sudo mkdir -p /usr/share/nginx
sudo unzip latest.zip -d /usr/share/nginx/

第 7 步：为 WordPress 网站创建数据库和用户

mysql  -u root -p

create database wordpress;
flush privileges;
exit;

第 8 步：配置 WordPress

cd /usr/share/nginx/wordpress/
sudo cp wp-config-sample.php wp-config.php
sudo vim wp-config.php

找到以下行，并将下方中文文本替换为您在上一步中创建的数据库名称、用户名和密码

/** The name of the database for WordPress */
define('DB_NAME', ' wordpress');/** MySQL database username */
define('DB_USER', 'root');/** MySQL database password */
define('DB_PASSWORD', '这里是你自己设置的密码');

sudo chown www-data:www-data /usr/share/nginx/wordpress/ -R

第 9步：为 WordPress 创建 Nginx 服务器块

sudo vim /etc/nginx/conf.d/wordpress.conf

将以下文本放入文件中

server {listen 80;listen [::]:80;server_name www.wordpress wordpress;root /usr/share/nginx/wordpress/;index index.php index.html index.htm index.nginx-debian.html;location / {try_files $uri $uri/ /index.php;}location ~ ^/wp-json/ {rewrite ^/wp-json/(.*?)$ /?rest_route=/$1 last;}location ~* /wp-sitemap.*\.xml {try_files $uri $uri/ /index.php$is_args$args;}error_page 404 /404.html;error_page 500 502 503 504 /50x.html;client_max_body_size 20M;location = /50x.html {root /usr/share/nginx/html;}location ~ \.php$ {fastcgi_pass unix:/run/php/php8.1-fpm.sock;fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;include fastcgi_params;include snippets/fastcgi-php.conf;fastcgi_buffers 1024 4k;fastcgi_buffer_size 128k;# Add headers to serve security related headersadd_header X-Content-Type-Options nosniff;add_header X-XSS-Protection "1; mode=block";add_header X-Permitted-Cross-Domain-Policies none;add_header X-Frame-Options "SAMEORIGIN";}#enable gzip compressiongzip on;gzip_vary on;gzip_min_length 1000;gzip_comp_level 5;gzip_types application/json text/css application/x-javascript application/javascript image/svg+xml;gzip_proxied any;# A long browser cache lifetime can speed up repeat visits to your pagelocation ~* \.(jpg|jpeg|gif|png|webp|svg|woff|woff2|ttf|css|js|ico|xml)$ {access_log        off;log_not_found     off;expires           360d;}}

sudo nginx -t
sudo systemctl reload nginx
