Copy the codeExecuting the above three commands in turn may require some patience.
We have installed Nginx, PHP and MySQL, but this service is not available for the time being. We need to link Nginx and PHP through configuration. First, we need to go to the Nginx configuration directory.
CD /etc/nginx/sites-enabled sudo nano default # if you want to use this method to modify the default.conf file, CTRL + S to save, CTRL +x to launch; #sudo apt install nano; Install nano, or use the built-in VI editor.Copy the codeThen paste in the following code
server { listen 80; root /usr/share/nginx/html; PHP ${fastcgi_pass Unix :/run/ PHP /php7.2-fpm.sock; Php7.2-fpm. Sock is running in the /run/ PHP directory. You may need to check the sock file for different versions of php-fpm. fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; }}Copy the codeTesting the PHP environment
cd /usr/share/nginx/html
sudo nano info.php
Copy the codeIn the editor
<? php phpinfo(); ? >Copy the codeOpen the http://localhost/info.php or http://. Your IP address/info PHP, see below content which PHP environment with success
2. Install wordpress

Copy the codeSynchronize the above DB configuration _ to the WordPress configuration _ file.
cd /etc/wordpress
sudo nano wp-config.php
Copy the codeSee the code below for configuration

CD /usr/share/wordpress sudo nano wp-configCopy the codeTo modify the nginx configuration file, see the following configuration
server { listen 80; root /usr/share/wordpress; location / { index index.php index.html index.htm; try_files $uri $uri/ /index.php index.php; PHP ${fastcgi_pass Unix :/run/ PHP /php7.2-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; }}Copy the codeRestart the nginx
sudo service nginx restart
Copy the codeOpen HTTP :localhost/wp-admin/install.php to install wordpress. Just enter the information as required
Successful installation
Third, summarize the existing problems
- If you want to upload the wordpress version to the host by yourself, you need to change the corresponding folder (mine is /usr/share/wordpress) permission to the www-data user, otherwise you will enter the FTP server information in the installation theme or plug-in.
- The configuration file in /etc/wordpress should have the same content as the wp-config.php configuration file. Otherwise, an error will be reported that the configuration file is not present.
- The mysql database is root and the password is empty.
