I installed Alfresco Community 6.1.2 on CentOS7. The section on ImageMagick just says to install it. I used the command:
yum install ImageMagick ImageMagick-devel
The alfresco.log shows the error:
2019-08-02 14:09:16,595 ERROR [org.alfresco.repo.content.transform.magick.ImageMagickContentTransformerWorker] [localhost-startStop-1] Remote ImageMagick is not available for transformations. 07020018 Remote ImageMagick check failed to connect or to read the response
This appears to be a misconfiguration in alfresco-global.properties. I have tried various alternates of the settings but this error stays..
I know this is an old thread, but I was searching how to configure ImageMagick in Alfresco Community 5.2 and I was able to find this configuration file from Keensoft that contained a working configuration for ImageMagick installed into CentOS with Yum. I imagine this should work with other Alfresco versions too
