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

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

systemctl start mysqld
service mysql start

service mysqld start

檢查mysql啟動是否正常
service mysqld status 或者 ps -ef | grep mysql

設置mysqld服務開機自啟動
systemctl enable mysqld.service

檢查mysqld開機自啟動是否設置成功
systemctl list-dependencies | grep mysqld
