1. 下載wget（一個下載文件的工具）： yum -y install wget

2. 下載tar包，這里使用wget從官網下載：
   wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

//wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz

3. 解壓
   tar -xvf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

4 . 移動
mv mysql-5.7.22-linux-glibc2.12-x86_64 /usr/local/

5 . 重命名
mv /usr/local/mysql-5.7.22-linux-glibc2.12-x86_64 /usr/local/mysql

6. 新建data目錄
   mkdir /usr/local/mysql/data

7 mysql用戶組
groupadd mysql

mysql用戶
useradd mysql -g mysql

8將/usr/local/mysql的所有者及所屬組改為mysql
chown -R mysql.mysql /usr/local/mysql

9 配置
/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data --initialize

如果出現以下錯誤：
/usr/local/mysql/bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory

則執行以下命令：
yum -y install numactl

完成后繼續安裝：
/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data --initialize

10 vim /etc/my.cnf

[mysqld]
datadir=/usr/local/mysql/data
basedir=/usr/local/mysql
socket=/tmp/mysql.sock
user=mysql
port=3306
character-set-server=utf8
# 取消密碼驗證
skip-grant-tables
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# skip-grant-tables
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

7、開啟服務

將mysql加入服務

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql

開機自啟

chkconfig mysql on

開啟

service mysql start

8、設置密碼

登錄（由于/etc/my.cnf中設置了取消密碼驗證，所以此處密碼任意）

/usr/local/mysql/bin/mysql -u root -p

操作mysql數據庫

use mysql;

修改密碼

update user set authentication_string=password('你的密碼') where user='root';

flush privileges;

exit;

9、將/etc/my.cnf中的skip-grant-tables刪除

10、登錄再次設置密碼（不知道為啥如果不再次設置密碼就操作不了數據庫了）

/usr/local/mysql/bin/mysql -u root -p

ALTER USER 'root'@'localhost' IDENTIFIED BY '修改后的密碼';

exit;

11、允許遠程連接

/usr/local/mysql/bin/mysql -u root -p

use mysql;

GRANT ALL PRIVILEGES ON . TO 'root'@'%' IDENTIFIED BY '123456'

flush privileges;

eixt;

12、添加快捷方式

ln -s /usr/local/mysql/bin/mysql /usr/bin

在Win10上安裝并配置完成MySQL-5.7.22，修改第一次密碼并登陸后，不論輸入什么語句，都出現提示“You must reset your password using ALTER USER...”的提示錯誤語句，解決辦法如下：

SET PASSWORD = PASSWORD('新密碼');
ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
FLUSH PRIVILEGES;
quit后，重新使用新密碼登陸即可進行操作了。
