CentOs6.5下mysql5.7.19二进制安装是我自己编译的官方源码包
首先我们把一些依赖包安装上：
yum -y groupinstall "Development tools" yum -y install ncurses ncurses-devel openssl-devel bison gcc gcc-c++ make解压mysql二进制安装包：
tar -zxvf mysql-5.7.19.tar.gz -C /usr/local/mysql编辑my3306.cnf

useradd mysql创建mysql相关数据目录
mkdir -p /home/mysql3306/msyql3306 mkdit -p /home/mysql3306/logs给mysql相关目录进行授权
chown -R mysql:mysql /home/mysql3306 chown -R mysql:mysql /usr/local/mysql初始化mysql

vim /etc/profile export PATH=$PATH:/usr/local/mysql/bin进入mysql
mysql -S /tmp/mysql3306.sock修改mysql用户密码
