1.系统约定
安装文件下载目录：/data/software
Mysql目录安装位置：/usr/local/mysql
数据库保存位置：/data/mysql
日志保存位置：/data/log/mysql
2.下载mysql
在官网：http://dev.mysql.com/downloads/mysql/ 中，选择以下版本的mysql下载：
执行如下命名：
#mkdir /data/software
#cd /data/software
--下载安装包
--建议：在windows上使用迅雷下载，速度很快（我的是1M/s），然后用工具（Xftp）上传到 /data/software目录下；
#wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz
3解压压缩包到目标位置
#cd /data/software
--解压压缩包
#tar -xzvf /data/software/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz
--移动并修改文件名
#mv /data/software/mysql-5.7.17-linux-glibc2.5-x86_64 /usr/local/mysql
4.创建数据仓库目录
--/data/mysql 数据仓库目录
# mkdir /data/mysql
#ls /data/
5.新建mysql用户、组及目录# ---新建一个msyql组
# useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql ---新建msyql用户禁止登录shell
6.改变目录属有者
#cd /usr/local/mysql
#pwd
#chown -R mysql .
#chgrp -R mysql .
#chown -R mysql /data/mysql
7.配置参数
# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
此处需要注意记录生成的临时密码，如上文结尾处的：YLi>7ecpe;YP
#bin/mysql_ssl_rsa_setup --datadir=/data/mysql
8.修改系统配置文件
#cd /usr/local/mysql/support-files
# cp my-default.cnf /etc/my.cnf
# cp mysql.server /etc/init.d/mysql
# vim /etc/init.d/mysql
修改以下内容：
9.启动mysql
# /etc/init.d/mysql start
--登陆
# mysql -hlocalhost -uroot -p
--如果出现：-bash: mysql: command not found
--就执行： # ln -s /usr/local/mysql/bin/mysql /usr/bin --没有出现就不用执行
--输入第6步生成的临时密码
--修改密码
mysql> set password=password('root');
--设置root账户的host地址（修改了才可以远程连接）
mysql>grant all privileges on *.* to 'root'@'%' identified by 'root';
mysql>flush privileges;
--查看表
mysql> use mysql;
mysql> select host,user from user;
--这里就可以使用远程连接测试了；
10.添加系统路径
# vim /etc/profile
添加：
export PATH=/usr/local/mysql/bin:$PATH
如下：
# source /etc/profile
11.配置mysql自动启动# chmod 755 /etc/init.d/mysql
# chkconfig --add mysql
# chkconfig --level 345 mysql on
以上就是linux环境Mysql 5.7.13安装教程，希望对大家的学习有所帮助。
补充：
--退出mysql命令窗口
#exit
--查看mysql状态
#service mysql status
--停止mysql
#service mysql stop
--启动mysql
#service mysql start
附my.cnf（这是一个配置mysql配置文件，暂时可以不用管，如你想钻研 你可以百度或google “mysql my.cnf 配置详情”）
/etc/my.cnf
