Those who do not want to build Nginx from source to get Nginx Cache Purge Module Can Test Official apt or yum version of nginx-extras version. Usually while writing tutorials we write for deb GNU/Linux and give instruction to install nginx-full instead of only nginx i.e. – apt-get install nginx-full instead of apt-get install nginx. Basically we have not seen any difference in performance between nginx-full, nginx-light and nginx with our availble minimum RAM (1GB on HP Cloud).
Nginx Cache Purge With nginx-extras : What Are the Differences Among These Versions?
There can be trouble with nginx-naxsi. nginx-naxsi has/had cache-purge third party module. For at least current Ubuntu official repository, if you run this command :
|
1 |
apt-cache depends nginx | tail -n+2 | cut -d: -f 2 | sort -u |
You will get nginx-extras, nginx-full and nginx-light
Technically nginx-extras should get the cache-purge third party module. This is not from our production server but it is up to date :

To see nginx-naxsi, you can to run this command :
|
1 |
dpkg -s nginx |
On Debian nginx-extras, we are getting these :

Nginx Cache Purge With nginx-extras : What Will Happen if Cache-Purge Missing or How I Will Upgrade?
If there is no cache-purge, the cache-purge will not work! You need to follow one of these four :
- Not doing anything
- Building nginx with the needed modules
- Using Nginx Extras
- Using Nginx Plus (Premium Version)
Building Nginx is the best option, next option is using an apt or yum version which has the cache-purge module. On a test instance try each of them. Nginx Plus is not required by all.
