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

创建mysql用户
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
/usr/local/mysql/bin/mysqld --defaults-file=/etc/my3306.cnf --initialize-insecure --explicit_defaults_for_timestamp --basedir=/usr/local/mysql --datadir=/home/mysql3306/mysql3306/ --user=mysql
启动mysql
/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my3306.cnf --datadir=/home/mysql3306/mysql3306/ --user=mysql &
配置环境变量
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
mysql>UPDATE user SET authentication_string=password('root123') WHERE User='root' AND Host='localhost';
