vim /data/log/mysql/error.log

查看初始化密码
grep "temporary password" /data/log/mysql/error.log

cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system

mkdir -p /var/run/mysqld/
chown mysql:mysql /var/run/mysqld

systemctl start mysqld
service mysql start

service mysqld start

检查mysql启动是否正常
service mysqld status 或者 ps -ef | grep mysql

设置mysqld服务开机自启动
systemctl enable mysqld.service

检查mysqld开机自启动是否设置成功
systemctl list-dependencies | grep mysqld

 ALTER USER "root"@"localhost" IDENTIFIED BY "Studytime%";

select host, user from user;
update user set host = "%" where user = "root";
GRANT ALL PRIVILEGES ON *.* TO "root"@"%" IDENTIFIED BY "Studytime%" WITH GRANT OPTION;
FLUSH PRIVILEGES;
