1、下载二进制文件
cd /data wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.16-linux-glibc2.5-x86_64.tar.gz
2、下载mysql解压到/opt/mysql下
cd /opt mkdir mysql cd mysql tar -zxvf /data/mysql-5.7.16-linux-glibc2.5-x86_64.tar.gz
3、创建一个软连接
cd /usr/local/ ln -s /opt/mysql/mysql-5.7.16-linux-glibc2.5-x86_64 mysql
4、创建用户
groupadd mysql useradd -M -g mysql -s /sbin/nologin -d /usr/local/mysql mysql
5、给予我们的配置文件定的环境，创建基本的目录
mkdir /data/mysql mkdir -p /data/mysql/mysql3306/{data,logs,tmp} chown -R mysql:mysql /data/mysql/mysql3306
备注：
创建/etc/my.cnf
6、做MySQL初始化
cd /usr/local/mysql/ ./bin/mysqld --initialize ./bin/mysqld --defaults-file=/etc/my.cnf --initialize
注：initialize必须放在最后
查看密码
cat /data/mysql/mysql3306/data/error.log | grep password
7、创建一个启动脚本
cd /usr/local/mysql/ cp support-files/mysql.server /etc/init.d/mysql
8、启动和关闭
/etc/init.d/mysql start | stop | restart
9、添加环境变量
echo "export PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile source /etc/profile
10、进入mysql更改密码
mysql -S /tmp/mysql.sock -p mysql>alter user user() identified by 'mysql'
11、mysql -uroot -p 密码为mysql
