tar -zxvf mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz
cp -r mysql-5.6.33-linux-glibc2.5-x86_64/* /usr/local/mysql

./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/mysql
首次安装可能会报错：

9.配置环境变量
vim /etc/profile
export PATH=$PATH:/usr/local/mysql/bin
10.启动服务
#启动mysql
service mysqld start
service mysqld stop
service mysqld status
或者使用如下命令操作mysql：
systemctl restart mysqld.service
systemctl start mysqld.service
