在官網：http://dev.mysql.com/downloads/mysql/ 中，選擇以下版本的mysql下載：

1、解壓壓縮包到目標位置

--解壓壓縮包

[root@ecs-1b35-0002 tools]# tar -zxvf mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz

--移動並修改文件名

[root@ecs-1b35-0002 tools]# mv mysql-5.7.25-linux-glibc2.12-x86_64 ../yoodb/mysql
[root@ecs-1b35-0002 mysql]# pwd
/home/yoodb/mysql

2、創建數據倉庫目錄

[root@ecs-1b35-0002 mysql]# mkdir data/mysql

新建mysql用戶、組及目錄

[root@ecs-1b35-0002 mysql]# groupadd mysql
[root@ecs-1b35-0002 mysql]# useradd -r -s /sbin/nologin -g mysql mysql -d /home/yoodb/mysql

3、改變目錄屬有者

[root@ecs-1b35-0002 mysql]# chown -R mysql .
[root@ecs-1b35-0002 mysql]# chgrp -R mysql .
[root@ecs-1b35-0002 mysql]# chown -R mysql /data/mysql
[root@ecs-1b35-0002 data]# cd ..
[root@ecs-1b35-0002 mysql]# chown -R mysql data/mysql
[root@ecs-1b35-0002 mysql]# ls
bin COPYING data docs include lib man README share support-files

4、配置參數

[root@ecs-1b35-0002 mysql]# bin/mysqld --initialize --user=mysql --basedir=/home/yoodb/mysql --datadir=/home/yoodb/mysql/data/mysql

7、修改以下內容

[root@ecs-1b35-0002 mysql]# vi /etc/my.cnf
[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
port=3307
datadir=/home/zkjc/mysql/data/mysql
skip-grant-tables
[root@ecs-1b35-0002 mysql]# /etc/init.d/mysql start
Starting MySQL.Logging to '/home/yoodb/mysql/data/mysql/ecs-1b35-0002.novalocal.err'.
 SUCCESS!

8、啓動mysql

[root@ecs-1b35-0002 mysql]# ln -s /home/yoodb/mysql/bin/mysql /usr/bin
[root@ecs-1b35-0002 my.cnf.d]# service mysql start
[root@ecs-1b35-0002 mysql]# mysql -hlocalhost -uroot -p
Enter password: 輸入生成的臨時密碼
Welcome to the MySQL monitor. Commands end with ; or \g.

--修改密碼
mysql> set password=password('yoodb123!@#');
Query OK, 0 rows affected, 1 warning (0.00 sec)
--設置root賬戶的host地址（修改可以遠程連接）
mysql> grant all privileges on *.* to 'root'@'%' identified by 'root';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> exit;
Bye

這樣就可以使用遠程連接數據了。

9、添加系統路徑

# vim /etc/profile

添加：

export PATH=/home/yoodb/mysql/bin:$PATH
[root@ecs-1b35-0002 mysql]# source /etc/profile

10、配置mysql自動啓動

[root@ecs-1b35-0002 mysql]# chmod 755 /etc/init.d/mysql
[root@ecs-1b35-0002 mysql]# chkconfig --add mysql
[root@ecs-1b35-0002 mysql]# chkconfig --level 345 mysql on
