CentOS 6.5 二进制安装MysqL 5.6
--------------------------------
下载MysqL5.6二进制包
mysql-5.6.20-linux-glibc2.5-x86_64.tar.gz
安装相关依赖包
yum install libaio*
useradd MysqL
tar zxvf mysql-5.6.20-linux-glibc2.5-x86_64.tar.gz -C /data/
mv mysql-5.6.20-linux-glibc2.5-x86_64 MysqL
修改MysqL的各级文件夹和文件的创建者、创建组为MysqL（注意语句后面有个.）
chown -R MysqL.MysqL /data/MysqL
至此MysqL已经安装完了，
但还需要初始化，初始化MysqL表、test表、infomation表等。
