1.下载二进制安装包
mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
tar -xvf mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz

2.拷贝安装包和配置文件(如果没有特殊情况，将安装包解压放置在该目录)
cp -rf mysql /usr/local/mysql
cp -rf my5.6.cnf /etc/my.cnf

3.创建mysql用户
useradd mysql

4.添加数据目录
mkdir -p /home/mysql3306/mysql3306
mkdir -p /home/mysql3306/logs

5.修改目录权限
chown mysql:mysql -R /home/mysql3306

6.修改配置文件
socket = /tmp/mysql.sock(socket文件存放位置)
datadir = /home/mysql3306/mysql3306(数据文件存放目录)
server-id= 12013306(设置serverid 命名规则:ip后两位+端口号)
port= 3306(启动端口)
innodb_buffer_pool_size = 1024M(innodb buffer pool大小)
*如果是核心节点单实例 配置成系统总内存的75%左右，如果不是核心节点则按照具体业务压力来设置

7.初始化数据库(确认2个OK)
