The system is CENTOS5.9.

Http://nginx.org/packages/centos/5/noarch/RPMS/nginx-release-centos-5-0.el5.ngx.noarch.rpm wget-c

Mkdir-p/home/proxy_cache_dir # The two folders proxy_cache_dir and proxy_temp_dir must be in the same partition.

Chown nginx. nginx-R proxy_cache_dir proxy_temp_dir # Set the directory owner

Chmod-R 777 proxy_cache_dir proxy_temp_dir # Set Directory Permissions

Back up the original configuration file

Cd/etc/nginx

Mv nginx. conf nginx. conf. bak

Mv conf. d/default. confconf. d/default. conf. bak

The following is the configuration file nginx. conf that I configured.

User nginx;

# Note: The paths specified by proxy_temp_path and proxy_cache_path must be in the same partition.
Proxy_temp_path/home/proxy_temp_dir;
# Set the name of the Web cache area to cache_one. The size of the memory cache space is 200 MB. cache is cleared once a day, and the size of the hard disk cache space is 10 GB.
Proxy_cache_path/home/proxy_cache_dir levels = keys_zone = NAME: 64 m inactive = 1d max_size = 10g;

}

Default Configuration File conf. d/default. conf

This file prohibits access by Unbound Domain names or IP addresses.

Server {
Listen 80 default;
Server_name _;
Return 500;
Access_log off;
}

The following is the configuration file conf. d/blog. conf of the reverse proxy of the website.

Server {
Listen 80;
Server_name blog.com; # website Domain Name
Location /{
Proxy_pass http://www.google.com;
Proxy_redirect off;
Proxy_set_header X-Real-IP $ remote_addr;
Proxy_set_header X-Forwarded-For $ proxy_add_x_forwarded_for;
Proxy_cache NAME; # use the NAME keys_zone
Proxy_cache_valid 200 302 1 h; # status codes 200 and 302 are saved for 1 hour
Proxy_cache_valid 301 1d; # Save the status code for one day
Proxy_cache_valid any 1 m; # Save the remaining one minute
}
}

You can copy multiple conf. d/blog. conf files from multiple websites to modify the corresponding website. Then you can complete the configuration and restart NGINX.

Server nginx restart

Then observe the cache directory

Tree/home/proxy_cache_dir

If a file is generated, the reverse proxy server is successfully cached !!
