来源：互联网发布：数据仿真软件编辑：程序博客网时间：2024/06/06 06:38

当前linux版本 AliCloud Linux 4.4.6-3

{ 具体路径自行修改 }

1.准备安装包mysql-5.7.13 (官网地址: http://dev.mysql.com/downloads/mysql/ )(低版本的不知道还有没有)

2. 添加一个mysql组 (命令)

[root@localhost ~]# groupadd mysql

3.添加一个用户mysql
[root@localhost ~]# useradd -g mysql mysql

4.解压tar包(文件在/usr/tmp中解压)

[root@localhost tmp]# tar -xzvf mysql-5.7.13.tar.gz

5 然后重命名解压后的包 ,命名为mysql

[root@localhost tmp]# mv mysql-5.7.13 mysql

6. 查看tmp临时包移动 mysql包到usr/local 中

[root@localhost tmp]# mv /mysql /usr/loca/

7. cd进入mysql中给这个包授权给mysql用户

[root@localhost tmp]# cd /usr/local/mysql

[root@localhostmysql]# chown –R mysql .

[root@localhostmysql]# chgrp –R mysql .

8. 配置参数 ( basedir 为mysql 的路径， datadir 为mysql的 data 包，里面存放着mysql自己的包)

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

9.记住临时密码(最后的密码)

2017-01-05T05:07:29.086486Z 1 [Note] A temporary password is generated for root@localhost:K07xmF?pX%Gh

然后执行

[root@localhost mysql]# #bin/mysql_ssl_rsa_setup --datadir=/data/mysql

10. cd到当前 /support-files 下 ,复制两个文件到 etc 和/etc/init.d/ 下

11、[root@localhost support-files]# cp my-default.cnf /etc/my.cnf

12、[root@localhost support-files]# cp mysql.server /etc/init.d/mysql

13. 修改basedir= 自己的路径修改datadir= 自己的路径

(本人: basedir=/usr/local/mysql bindir=/usr/local/mysql/bin)

[root@localhost support-files]# vim /etc/init.d/mysql

14. 启动mysql (如果不行可以使用命令: service mysql start 启动)

[root@localhost mysql]# bin/mysqld_safe --user=mysql &

15. 登录(输入临时密码注意大小写),登录后提示欢迎语,

[root@localhost mysql]# bin/mysql --user=root -p
Enter password:

16.在 sqlplus 命令行下修改密码

mysql>set password=password('123456');

授权

mysql>grant all privileges on *.* to root@'%' identified by '123456';

刷新

mysql>flush privileges;

mysql>use mysql;

mysql>select host,user from user;
