create database gearman;
grant all privileges on gearman.* to gearman@localhost identified by 'xxxx';创建gearman库，创建gearman用户，并授权。使gearman程序可以调用mysql队列。
#安装gearman
yum -y install libgearman-1.1.12
yum -y install gearmand-1.1.12
echo "### Settings for gearmand" >/etc/sysconfig/gearmand
echo 'OPTIONS=" --log-file /var/log/gearmand/gearmand.log -q mysql --mysql-user gearman --mysql-password xxxx --mysql-db gearman"' >> /etc/sysconfig/gearmand echo写入的内容有""时，需要用''代替echo格式的双引号。

#安装leptonica
yum -y install gcc gcc-c++ make
yum -y install autoconf automake libtool
yum -y install libjpeg-devel libpng-devel libtiff-devel zlib-devel 需要先安装这些依赖包
wget http://www.leptonica.org/source/leptonica-1.72.tar.gz
tar zxvf leptonica-1.72.tar.gz
cd leptonica-1.72
./configure
make
make install
#安装tesseract-ocr
wget https://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.02.02.tar.gz
tar zxvf tesseract-ocr-3.02.02.tar.gz
cd tesseract-ocr/
./autogen.sh
./configure
make
make install
ldconfig
cd /root/
wget https://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.02.eng.tar.gz
