Nginx Proxy Cache Redis WordPress Centos
Understanding Nginx Proxy Cache
Nginx Proxy Cache is a web-acceleration software from Nginx, Inc. It is designed to speed up dynamic web content delivery. It runs on a Linux server and works by caching responses from webservers. When a request is made for a web page, the proxy server checks its cache to see if it already contains the response for that page. If it does, the cached version of the page is delivered directly to the user and the response from the webserver is bypassed. This reduces server load and increases response times.
Nginx Proxy Cache also helps protect the underlying webserver from malicious requests. It limits the number of requests per second that can be made to the webserver. This reduces the chance of a DoS attack against the underlying webserver. It can also help prevents the webserver from being overwhelmed by too many requests and protecting it from malicious traffic.
Setting Up Nginx with Redis for WordPress
If you are running a WordPress website on a Centos system, you can install the Nginx proxy cache along with the Redis caching engine. Redis is an in-memory data structure store that is designed to speed up data-intensive applications. By combining Nginx and Redis, your WordPress website can be served faster than ever.
The first step is to install the Nginx and Redis packages. On CentOS, this can be done with the following commands:
yum -y install nginx redis
service nginx start
service redis start
Once the packages have been installed, you will need to configure Nginx to use the Redis cache. This can be done by editing the Nginx config file. Add the following code to the end of the config file:
proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=my_zone:10m inactive=60m;
This tells Nginx to use the /var/cache/nginx folder as the storage location for the Redis cache. It also sets a maximum cache size of 10MB, and sets the inactive period to 60 minutes.
Once the config file has been edited, you will need to restart Nginx. This can be done with the following command:
service nginx restart
Using Nginx to Serve WordPress Content
Once Nginx and Redis have been configured, you can start serving content from the cache. This reduces the amount of load that will be placed on the webserver, thus allowing for faster response times. The best way to do this is to configure WordPress to use Nginx as an external caching engine.
To do this, you will need to edit the WordPress config file. Add the following code to the file:
define('WPCACHEHOME', '/var/cache/nginx');
This tells WordPress to use Nginx as an external caching engine. You may also need to configure the wp-config.php file to enable caching. To do this, add the following code to the file:
define('WPCACHEENABLED', true);
Once the changes have been saved, WordPress will start using Nginx to serve content from the Redis cache.
Configuring Nginx for WordPress
Once Nginx and Redis have been configured, you will need to configure Nginx for WordPress. This can be done by creating a virtual host entry in the config file. Add the following code to the file:
server {
listen 80;
server_name *yourdomain.com;
root /var/www/yourdomain.com;
index index.php index.html;
location / {
try_files $uri $uri/ /index.php;
}
location ~ .php$ {
include fastcgi_params;
fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
location ~ /.ht {
deny all;
}
}
This will configure Nginx to serve content from the WordPress website. Save the changes and restart Nginx with the following command:
service nginx restart
Configuring Redis for WordPress
Once Nginx has been configured, you will need to configure Redis. This can be done by editing the redis.conf file. Add the following code to the file:
maxmemory 10485760
maxmemory-policy allkeys-lru
This sets the maximum memory limit for Redis to 10MB, and sets the eviction policy to LRU (Least Recently Used). Once the changes have been saved, restart Redis with the following command:
service redis restart
Monitoring Performance with Nginx Proxy Cache
Once Nginx and Redis have been configured, you will need to monitor the performance of the system. This can be done with the Nginx access log. This will provide you with insight into how the cache is performing. If you find that the cache is not performing as expected, you may need to adjust the settings in the nginx config file.
Conclusion
Nginx Proxy Cache and Redis are powerful tools to speed up the delivery of dynamic web content. By combining both technologies, you can reduce the server load and response times of your WordPress website on Centos. It is important to monitor the performance of Nginx and Redis, and make adjustments to the configuration as needed.
