Tesseract 部署到centos遇到的坑

1、java.lang.UnsatisfiedLinkError: Unable to load library 'tesseract': Native library (linux-x86-64/libtesseract.so) not found in resource path

　　和 at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:303) ~[jna-4.5.2.jar!/:4.5.2 (b0)]

解决方法：

你需要在centos 安装一些图像的包
yum -y install libjpeg* libpng* freetype* gd* giflib* libtiff* zlib*
然后安装tesseract包
yum install tesseract
安装之后，需要让程序调用，所以要暴露出来
通过rpm -qal | grep tesseract 查找安装的文件
命令打开这个文件，vim ~/.bash_profile
添加下面两个

　　LD_LIBRARY_PATH=/usr/lib64/

　　export LD_LIBRARY_PATH

再运行source ~/.bash_profile 使文件生效

2、碰到这种错误，那就是你的内存不足了，换机器或者添加内存吧

Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory.
