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)

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:

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;
