step 1 :
yum install tesseract -y
查看 tesseract -v
step 2: install more language
yum install -y tesseract-langpack-rus

1 安装centos系统依赖
yum install -y automake autoconf libtool gcc gcc-c++yum install -y libpng-devel libjpeg-devel libtiff-devel
--部分新服务器需要 yum install gtk2-devel yasm glibc.i686 libstdc++.so.6 libgtk-x11-2.0.so libatk-1.0.so.0 libcairo.so.2 libcups.so.2 libgdk-x11-2.0.so.0 libgdk_pixbuf-2.0.so.0 libgtk-x11-2.0.so.0 libpango-1.0.so.0 libpangocairo-1.0.so.0 libICE.so.6 libSM.so.6 libmng.so.1 libpng12.so.0 libGLU.so.1 -y

安装leptonica
wget http://www.leptonica.org/source/leptonica-1.72.tar.gztar xvzf leptonica-1.72.tar.gz
cd leptonica-1.72/./configure --prefix=/usr/local/
make &&make install
配置环境
vim /etc/bashrc
加入
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH
CPLUS_INCLUDE_PATH=$CPLUS_INCLUDE_PATH:/usr/local/include/export CPLUS_INCLUDE_PATH
C_INCLUDE_PATH=$C_INCLUDE_PATH:/usr/local/leptonica/include/leptonica
export C_INCLUDE_PATH
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH
LIBRARY_PATH=$LIBRARY_PATH:/usr/local/lib
export LIBRARY_PATH
TESSDATA_PREFIX=/usr/local/share/tessdataexport TESSDATA_PREFIX
最后刷新
source/etc/bashrc
vim /etc/profile
在最后插入
export LD_LIBRARY_PATH=$LD_LIBRARY_PAYT:/usr/local/lib
export LIBLEPT_HEADERSDIR=/usr/local/include
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
source /etc/profile

安装tesseract-ocr
wget https://github.com/tesseract-ocr/tesseract/archive/3.04.zipunzip 3.04.zip
cd tesseract-3.04/
./autogen.sh
./configure --with-extra-includes=/usr/local/include --with-extra-libraries=/usr/local/include
make &&make install
sudo ldconfig
