2.解压它移动到对应目录下

tar -zxvf mysql-5.6.37-linux-glibc2.12-x86_64.tar.gz

cp ./mysql-5.6.37-linux-glibc2.12-x86_64 /usr/local/mysql

创建用户和组

groupadd mysql和useradd -r -g mysql mysq

进入源码目录

cd /usr/local/mysql/mysql-5.6.37-linux-glibc2.12-x86_64

创建data目录存放mysql 数据

mkdir data

修改目录的用户和组

chown -R mysql:mysql .

复制这个文件到init.d目录下 

加入开机自启动项

cp support-files/mysql.server /etc/init.d/mysqld

vi /etc/init.d/mysqld

basedir=/usr/local/mysql/mysql-5.6.37-linux-glibc2.12-x86_64

datadir=/usr/local/mysql/mysql-5.6.37-linux-glibc2.12-x86_64/data

初始化mysql

./scripts/mysql_install_db --use=mysql --basedir=/usr/local/mysql/mysql-5.6.37-linux-glibc2.12-x86_64
