ubuntu上搭建wordpress

前提条件：

1. php7.4 +
2. mysql 8+

参考ubuntu配置php环境和ubuntu上安装mysql

1. 下载源码，wget https://wordpress.org/latest.tar.gz
2. 解压，tar xzvf latest.tar.gz
3. 移动到/usr/share/nginx/html/wordpress
4. 配置nginx

server {
        listen 80;
        listen [::]:80;

        # SSL configuration
        #
        # listen 443 ssl default_server;
        # listen [::]:443 ssl default_server;
        #
        # Note: You should disable gzip for SSL traffic.
        # See: https://bugs.debian.org/773332
        #
        # Read up on ssl_ciphers to ensure a secure configuration.
        # See: https://bugs.debian.org/765782
        #
        # Self signed certs generated by the ssl-cert package
        # Don't use them in a production server!
        #
        # include snippets/snakeoil.conf;

        # root /var/www/html;
        # root /root/src/wordpress/wordpress;
        root /usr/share/nginx/html/wordpress;
        # root /usr/share/txy/wordpress;
        # Add index.php to the list if you are using PHP
        index index.php index.html index.htm index.nginx-debian.html;

        server_name wp.tangxuyang.cn;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }

        # pass PHP scripts to FastCGI server
        #
        location ~ \.php$ {
                include snippets/fastcgi-php.conf;

                # With php-fpm (or other unix sockets):
                # fastcgi_pass unix:/run/php/php7.4-fpm.sock;
                # With php-cgi (or other tcp sockets):
                # fastcgi_pass 127.0.0.1:9000;
                fastcgi_pass unix:/run/php/php8.1-fpm.sock;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                fastcgi_param QUERY_STRING $query_string;
        }

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #       deny all;
        #}
}

访问https://wp.tangxuyang.cn，开始设置wordpress吧

其实在这个过程中我还遇到一个问题，最终原因是wordpress目录属于root，权限是drwxr-x-r-x，而nginx的用户是www-data，虽然可以访问wordpress中的文件，但是没有创建权限，所以wordpress会让自行创建wp-config.php，刚开始我也傻傻地自己去创建。后面在上传图片是总报错，才知道是权限的问题，解决方法就是把wordpress目录给www-data，chown -R www-data:www-data wordpress
