亲爱的编程学习爱好者，如果你点开了这篇文章，说明你对《Linux下的mysql5.7的安装》很感兴趣。本篇文章就来给大家详细解析一下，主要介绍一下MySQL、Linux，希望所有认真读完的童鞋们，都有实质性的提高。

一、下载MYSQL
在官方网站下载MySQL安装包，下载地址: https://www.mysql.com/downloads/
安装MYSQL

1. 解压MySQL安装包

tar -zxvf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz 
mv mysql-5.7.22-linux-glibc2.12-x86_64 /usr/local/mysql

1. 添加系统用户和用户组

 groupadd mysql
 useradd -r -g mysql mysql

1. 创建MySQL数据目录

mkdir /usr/local/mysql/data

1. 修改MySQL目录权限

chown -R mysql:mysql /usr/local/mysql

1. 初始化数据库

 cd /usr/local/mysql
 ./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

1. 修改MySQL目录权限

 chown -R root:root ./
 chown -R mysql:mysql data

1. 添加启动服务

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

1. 修改MySQL配置文件

 vim /etc/my.cnf
 [mysqld]
 basedir=/usr/local/mysql
 datadir=/usr/local/mysql/data
 socket=/tmp/mysql.sock
 user=mysql
 port=3306
 character-set-server=utf8
 symbolic-links=0
 ​
 [mysqld_safe]
 log-error=/var/log/mysqld.log
 pid-file=/var/run/mysqld/mysqld.pid
 ​
 !includedir /etc/my.cnf.d

三、配置MySQL账号密码以及远程连接

1. 修改my.cnf配置

 [mysqld]
 datadir=/usr/local/mysql/data
 basedir=/usr/local/mysql
 socket=/tmp/mysql.sock
 user=mysql
 port=3306
 character-set-server=utf8
 # 跳过密码验证
 skip-grant-tables 
 symbolic-links=0
 ​
 [mysqld_safe]
 log-error=/var/log/mysqld.log
 pid-file=/var/run/mysqld/mysqld.pid
 ​
 !includedir /etc/my.cnf.d

1. 重启MySQL服务

service mysql restart

1. 设置用户登陆密码

 mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
 mysql> FLUSH PRIVILEGES;

1. 设置MySQL远程访问

 mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY '123456' WITH GRANT OPTION;
 mysql> FLUSH PRIVILEGES;
