Linux 上面安装mysql5.7.28

1.下载msyql安装包

2.通过软件把压缩包上传到linux上面去

3.把压缩包解压后,重命名

mv mysql..........(文件夹的名字) mysql

4.把msyql 放到 /usr/loca下

cp -r mysql /usr/local

5.在mysql下添加data目录

[root@localhost ~]# mkdir /usr/local/mysql/data

6.更改mysql目录下所有的目录及文件夹所属组合用户

[root@localhost /]# cd /usr/local/ 
[root@localhost local]# chown -R mysql:mysql mysql/
[root@localhost local]# chmod -R 755 mysql/

7.编译安装并初始化mysql，记住命令行末尾的密码：

[root@localhost local]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql

8.启动mysql服务

[root@localhost local]# /usr/local/mysql/support-files/mysql.server start

9.做个软链接,重启服务

[root@localhost local]# ln -s /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql 
[root@localhost local]# service mysql restart
Shutting down MySQL.. SUCCESS! 
Starting MySQL. SUCCESS!

10.做个软链接，将安装目录下的mysql 放在/usr/bin 目录下

[root@localhost local]# ln -s /usr/local/mysql/bin/mysql /usr/bin

11.登录msyql，输入密码（密码为步骤7初始化生成的密码）

[root@localhost local]# mysql -u root -p
Enter password:

12.修改密码并开放远程

msql>alter user 'root'@'localhost' identified by '123456';
mysql>use mysql;
msyql>update user set user.Host='%' where user.User='root';
mysql>flush privileges;
mysql>quit

13.编辑my.cnf，添加配置文件，配置内容为

[root@localhost local]# vi /usr/local/mysql/my.cnf
[mysqld]
port = 3306
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
