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]# mvmysql-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@localhost mysql]#chown –R mysql .

[root@localhost mysql]#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; ................................查看完毕 此后随意........................
