Installing redis on Nginx

⚠️ this is NGINX setup for bitnami stack, but can be used as guideline for other installs

Install redis server

/opt/wp248/scripts/wp-install-redis.sh

Edit redis config

sudo nano /etc/redis/redis.conf

redis config search and replace 1:

>> Search for:
supervised

>> Change to:
supervised systemd

redis config search and replace 2:

>> Search for:
# maxmemory-policy

>> Replace or Add after:
maxmemory-policy allkeys-lru

redis config search and replace 3:

Notes:

• Securing your redis command from external attack
• you can skip this for stand setup

>> Search for:
rename-command CONFIG ""

>> Add after:

#rename-command FLUSHDB ""
#rename-command FLUSHALL ""
rename-command DEBUG ""
rename-command SHUTDOWN WP248_SHUTDOWN
rename-command CONFIG WP248_CONFIG

redis config search and replace 4:

Notes:

• this parm based on your server configuration and free memory
• Skip this config if you are not sure

>> Search for:
# maxmemory <bytes>

>> Add after / replace if not comments:
maxmemory 256mb

Restart services

sudo systemctl restart redis

Test redis

redis-cli ping

# should return:
# PONG

Update php.ini and restart service

sudo pecl install redis
sudo nano /opt/bitnami/php/etc/php.ini
sudo /opt/bitnami/ctlscript.sh restart php-fpm nginx
sudo systemctl restart redis

Add wordpress config for redis

Notes:

• we adding [_] (underscore to the end at the domain name)
• the underscore at the end of the domain will help to see the right parm

cd /opt/bitnami/apps/wordpress/htdocs/
wp config set WP_CACHE_KEY_SALT YOURDOMAIN.COM_
wp plugin install redis-cache --activate

WordPress related tweaks for bitnami:

Define domain name for CLI:

sudo nano /opt/bitnami/apps/wordpress/htdocs/wp-config.php

search for:

if ( defined( 'WP_CLI' ) ) {
    $_SERVER['HTTP_HOST'] = 'localhost';
}

replace with:

if ( defined( 'WP_CLI' ) ) {
    $_SERVER['HTTP_HOST'] = 'YOUR-DOMAIN-NAME.COM';
}

Disable all debugs errors:

Add the following lines before:

/* That's all, stop editing! Happy publishing. */

ini_set('display_errors','Off');
ini_set('error_reporting', E_ALL );
define('WP_DEBUG', false);
define('WP_DEBUG_DISPLAY', false);

Enable all debugs errors:

Add the following lines before:

/* That's all, stop editing! Happy publishing. */

ini_set('display_errors','On');
ini_set('error_reporting', E_ALL );
define('WP_DEBUG', true);
define('WP_DEBUG_DISPLAY', true);
// comment this out to change the default error log locations
//define( 'WP_DEBUG_LOG', '/opt/bitnami/apps/wordpress/log/wp-errors.log' );
define( 'SCRIPT_DEBUG', true );

wp config set WP_DEBUG_LOG '/opt/bitnami/apps/wordpress/log/wordpress-errors.log'

Rename default admin user:

mysql -p -u bn_wordpress bitnami_wordpress

update wp_users  set user_email='webmaster@DOMAIN.com'  where user_login='user';
update wp_users  set user_login='NEW-USER-ID' where user_login='user';
