3、安装 mysql

yum  -y  localinstall ./mysql-community-*

4、修改配置文件(更改数据存放路径)

#创建数据存放文件夹
mkdir /data/mysql -p

#修改mysql配置文件
grep -v -E '^#|^$' /etc/my.cnf
[mysqld]
port=3306
default-storage-engine=InnoDB
max_connections=1200
datadir=/data/mysql
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
log_slave_updates=ON
log_bin=mysql-bin
binlog_format=ROW

5、启动并加入开机自启

systemctl enable --now mysqld

6、修改密码

# grep password /var/log/mysqld.log
2022-04-13T07:31:54.168545Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: hBHJda&;a7PL

# mysql -uroot -p
