1.下载mysql-8.0.25（https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.25-el7-x86_64.tar.gz）
2.上传到 /usr/local/mysql 目录，执行 tar -zxvf /usr/local/mysqlmysql-8.0.25-el7-x86_64.tar.gz
3.执行 /usr/local/mysqlmysql-8.0.25-el7-x86_64/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql/mysql-8.0.25-el7-x86_64 --datadir=/usr/local/mysql/mysql-8.0.25-el7-x86_64/data --pid-file=/usr/local/mysql/mysql-8.0.25-el7-x86_64/data/mysql.pid --explicit_defaults_for_timestamp （目的：以root用户名启动，初始化数据库，生产随机密码）
执行结果：
[root@hadoop03 mysql-8.0.25-el7-x86_64]# ./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql/mysql-8.0.25-el7-x86_64 --datadir=/usr/local/mysql/mysql-8.0.25-el7-x86_64/data --pid-file=/usr/local/mysql/mysql-8.0.25-el7-x86_64/data/mysql.pid --explicit_defaults_for_timestamp 2021-06-06T06:27:44.224106Z 0 [System] [MY-013169] [Server] /usr/local/mysql/mysql-8.0.25-el7-x86_64/bin/mysqld (mysqld 8.0.25) initializing of server in progress as process 80717 2021-06-06T06:27:44.238078Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started. 2021-06-06T06:27:45.442357Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended. 2021-06-06T06:27:48.173559Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: jma*_HL2yyzo
4.启动mysql服务 /usr/local/mysqlmysql-8.0.25-el7-x86_64/bin/mysqld &（最后的&为后台启动，可不写）
5.进入mysql /usr/local/mysqlmysql-8.0.25-el7-x86_64/bin/mysql -uroot -pjma*_HL2yyzo（密码为上面产生的随机密码）
7.修改密码并设置远程可连：
mysql> ALTER USER‘root‘@‘localhost‘ IDENTIFIED BY ‘123456‘; Query OK, 0 rows affected (0.00 sec) mysql> CREATE USER ‘root‘@‘%‘ IDENTIFIED BY ‘123456‘; Query OK, 0 rows affected (0.02 sec) mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ WITH GRANT OPTION; Query OK, 0 rows affected (0.01 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec)
