centos內yum包內的mysql-utilities不是最新版的。所以通過編譯的方式進行安裝。mysql-utilities-1.6.5是基於python2實現的，所以python不需要升級到3.
安裝步驟
cd /download
wget https://cdn.mysql.com/archives/mysql-utilities/mysql-utilities-1.6.5.tar.gz
tar xvf mysql-utilities-1.6.5.tar.gz
cd mysql-utilities-1.6.5
python setup.py build
python setup.py install
mysqldiff --version
