第一步：依赖安装

yum install -y autoconf automake libtool libjpeg libpng libtiff zlib libjpeg-devel libpng-devel libtiff-devel zlib-devel

第二步：下载安装Leptonica

下载：wget http://www.leptonica.org/source/leptonica-1.76.0.tar.gz  
解压：tar-zxvf leptonica-1.76.0.tar.gz  
安装：cd leptonica-1.76.0  
./configure  
make && make install

第三步：下载安装Tesseract-OCR

下载：wget https://github.com/tesseract-ocr/tesseract/archive/4.0.0-beta.3.tar.gz  
解压：tar-zxvf tesseract-4.0.0-beta.3.tar.gz  
安装：./autoconf  
提示错误信息"Missing autoconf-archive. Check the build requirements"  
解决办法：yum install autoconf-archive  
./configure  
提示错误信息"error: Leptonica 1.74 or higher is required. Try to install libleptonica-dev package"  
解决办法：参考csdn地址-https://blog.csdn.net/xjmxym/article/details/79040514  
按照上述文档操作之后，执行：  
./configure --with-extra-includes=/usr/local/include --with-extra-libraries=/usr/local/lib  
make && make install

第四步：检测Tesseract-OCR 支持的语言

切换Tesseract-OCR 指令安装目录：/usr/local/bin/tesseract --list-langs  
github下载全套tessdata\_fast并上传至/usr/local/share/文件夹下，将tessdata\_fast改名为tessdata，(建议下载需要的语言包：eng.traineddata、chi\_sim.traineddata)

第五步：Tesseract-OCR 识别指定图形文件，将识别结果输入到指定文件中

执行如下指令：/usr/local/bin/tesseract 识别图像路径 识别结果输出地址 -l chi\_sim  
Demo: /usr/local/bin/tesseract /ftp/pub/0002-0001.jpg /ftp/pub/1 -l chi\_sim
