1. install the environment yum install autoconf ImageMagick-devel.

Installation document:
Https://github.com/techblue/jmagick/blob/master/INSTALL

It seems that there is a problem with git cloning. Download the zip package directly.
The wget https://github.com/techblue/jmagick/archive/master.zipunzip jmagick-master.zipcd jmagick-masterautoconf./configure-with-java-home =/usr/java/default
Make allmake install
All the compilation and installation work is fine, and then the jar package and so files are under lib. In fact, it has been installed in/usr/local/lib/
-Rwxr-xr-x. 1 root 27609 Nov 27 jmagick-6.7.7.jar
-Rwxr-xr-x. 1 root 146606 Nov 27 libJMagick-6.7.7.so

3. tomcat startup Problems
You must add parameters when starting tomcat. Otherwise, initialization fails.
Java. lang. NoClassDefFoundError: cocould not initialize class magick. ImageInfo

Solution: Modify tomcat startup.
Modify catalina. sh and add the parameter after the annotation.
JAVA_OPTS = "-Djava. library. path =/usr/local/lib-Djmagick. systemclassloader = no-server-XX: PermSize = 256 M-XX: MaxPermSize = 1024 m-Xms512M-Xmx1024M-XX: MaxNewSize = 256 m"

4. Installation Package
The most important thing is the so file. If it has been compiled, you can copy the so file to other servers, instead of compiling it.
