如果改了目录，记得看看修改 /etc/apparmor.d/usr.sbin.mysqld 这里的 /var/lib , 重启 /etc/init.d/apparmor restart

rpm版本

https://downloads.mysql.com/archives/community/

https://downloads.mysql.com/archives/get/p/23/file/mysql-community-server-5.7.32-1.el7.x86_64.rpm
https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.32-1.el7.x86_64.rpm-bundle.tar

之后 tar -xvf  mysql-5.7.32-1.el7.x86_64.rpm-bundle.tar
yum localinstall ./*.rpm

service mysqld start
默认密码查看 /var/log/mysqld.log 的 password 关键字 (A temporary password is generated for root@localhost)

1804 的，修改路径 
apt-get install mysql-server
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY "123456";
use mysql;
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
flush PRIVILEGES;


services mysql stop
rsync -avz /var/lib/mysql/ /data/mysql/

/etc/mysql/mysql.conf.d/mysqld.cnf
- datadir 改成 /data/mysql/
- bind-address 改成 0.0.0.0


修改 /etc/apparmor.d/usr.sbin.mysqld 和 /usr/share/mysql/mysql-systemd-start
  /var/lib/mysql 相关的，增加多  /data/mysql

service apparmor reload

mkdir /run/mysqld/
chmod a+rw /run/mysqld/

mkdir /run/mysqld/
chmod a+rw /run/mysqld/
