Setup Wordpress From Scratch

This is a note on setting up wordpress on my arch.

Things you’ll need

php, nginx, mysql (mariadb) etc

sudo pacman -S php php-{fpm,gpsql,gd,cgi} uwsgi-plugin-php
sudo pacman -S mariadb libmariadbclient mariadb-clients
sudo pacman -S nginx

wordpress

prefer not using sudo pacman -S wordpress
While it is easier to let pacman manage updating your WordPress install, this is not necessary. WordPress has functionality built-in for managing updates, themes, and plugins.

download: wget https://wordpress.org/latest.tar.gz
extract: tar -xf latest.tar.gz
chown to your nginx worker:
- ps aux | grep nginx to see your worker’s name
- sudo chown -R http:http wordpress
move to somewhere like: sudo mv wordpress /srv/http/mysite.com, sudo mv wordpress /var/www/html/mysite.com

Setup database

enable startup: sudo systemctl enable mysqld.service
start now: sudo systemctl start mysqld.service
to make your MariaDB installation secure: sudo mysql_secure_installation (yes to all)
mysql -u root -p
- CREATE DATABASE mysite;
- CREATE USER ‘mysiteadmin’@’localhost’ IDENTIFIED BY ‘password’;
- GRANT ALL PRIVILEGES ON mysite.* TO ‘mysiteadmin’@’localhost’ IDENTIFIED BY ‘password’;
- FLUSH PRIVILEGES;
- EXIT;

Setup php

enable startup: sudo systemctl enable php-fpm
start now: sudo systemctl start php-fpm
sudo vim /etc/php/php.ini uncomment lines to enable some extensions
- extension=gd
- extension=mysqli
- extension=pgsql
you may need to restart php-fpm: sudo systemctl restart php-fpm

Setup nginx

enable startup: sudo systemctl enable nginx
start now: sudo systemctl start nginx
sudo vim /etc/nginx/nginx.conf
- comment or delete servers that you don’t need
- at the end of http block add: include sites-enablesd/*
sudo mkdir /etc/nginx/{sites-enabled,sites-available}

add server in sudo vim /etc/nginx/sites-available/mysite.com

server {
    listen 80;
    listen [::]:80;
    root /srv/http/mysite.com;
    index index.php index.html index.htm;
    server_name mysite.com;
    error_log /var/log/nginx/mysite.com_error.log;
    access_log /var/log/nginx/mysite.com_access.log;
    client_max_body_size 100M;
    location / { try_files $uri $uri/ /index.php?$args; }
    location ~ \.php$ {
        # 404
        try_files $fastcgi_script_name =404;

        # default fastcgi_params
        include fastcgi_params;

        # fastcgi settings
        fastcgi_pass			unix:/run/php-fpm/php-fpm.sock;
        fastcgi_index			index.php;
        fastcgi_buffers			8 16k;
        fastcgi_buffer_size		32k;

        # fastcgi params
        fastcgi_param DOCUMENT_ROOT	$realpath_root;
        fastcgi_param SCRIPT_FILENAME	$realpath_root$fastcgi_script_name;
        #fastcgi_param PHP_ADMIN_VALUE	"open_basedir=$base/:/usr/lib/php/:/tmp/";
    } 
}

add soft link to this server config: cd /etc/nginx/sites-enabled; ln -s ../sites-available/mysite.com mysite.com
reload config: sudo nginx -s reload

Setup wordpress

cd /srv/http/mysite.com/; sudo cp -p wp-config-sample.php wp-config.php
sudo vim wp-config.php, set information as in your database
- define( ‘DB_NAME’, ‘mysite’ );
- define( ‘DB_USER’, ‘mysiteadmin’ );
- define( ‘DB_PASSWORD’, ‘password’ );
go to your browser for more setups.

Trouble Shooting

in the wp-config.php file, change define('WP_DEBUG', false) to define('WP_DEBUG', true) to enable debugging information on your site.
