根目录:

[root@localhost ~]# mv mysql-8.0.19-linux-glibc2.12-x86_64 /usr/local/mysql
[root@localhost ~]# chown -R mysql.mysql /usr/local/mysql

进行初始化,默认密码为空:

[root@localhost ~]# /usr/local/mysql/bin/mysqld  --initialize-insecure --basedir=/usr/local/mysql --datadir=/data/mysql/ --user=mysql

查看日志有没有报错:

[root@localhost ~]# cat /data/mysql/mysql.err
2020-01-20T15:11:46.156633+08:00 0 [System] [MY-013169] [Server] /usr/local/mysql/bin/mysqld (mysqld 8.0.19) initializing of server in progress as process 14822

环境变量与开机自启:

[root@localhost mysql]# vim /etc/profile
#在最后添加
export MYSQL_HOME=/usr/local/mysql
PATH=$PATH:$MYSQL_HOME/bin/
[root@localhost mysql]# source /etc/profile

 [root@localhost mysql]# cd /usr/local/mysql
 [root@localhost mysql]# cp -f support-files/mysql.server /etc/init.d/mysqld

 [root@localhost mysql]# chmod 755 /etc/init.d/mysqld

 [root@localhost mysql]# chkconfig --add mysqld

 [root@localhost mysql]# chkconfig mysqld on

启动数据库:

[root@localhost mysql]# /etc/init.d/mysqld start
修改密码与创建用户,8.0已取消grant权限自动创建用户,要用create user创建用户再用grant赋予权限:
[root@localhost ~]# mysql -uroot -p
Enter password:
