Upload the locally developed WordPress directory to the home directory of the website that has been set by the server to ensure that the file directory relationship is correct. If you don't know the website home directory, you can check the settings in the website management background program or consult the website hosting operator. Uploading can be through FTP or other transmission methods supported by the website server. If the server supports compression, it is recommended to upload it after compression to speed up the transmission and ensure the integrity of the file format.
Upload the mysql database file corresponding to the local WordPress site on the server-side mysql database. If a new database is not created on the server, it needs to be uploaded after the new database is created. You can generally use database management tools such as phpmyadmin.
Modify the mysql server address, port, database name and user name of the corresponding server in the configuration file wp-config.php under the WordPress directory.
If the new domain name is different from the domain name of the local development environment, you need to modify the domain name field in the wp_options data table in the database to the new domain name on the server.
After all the above operations are completed, the new site should be accessible correctly.
