啟動MySql失敗

（我的MySQL是5.7）

# service mysqld restart
Redirecting to /bin/systemctl restart mysqld.service
Failed to restart mysqld.service:Unit not found.
//提示啟動失敗 
# /bin/systemctl restart mysqld.service
Failed to restart mysqld.service:Unit not found.
//還是失敗

突然想起好像以前啟動都是mysql，趕緊試一下

# /bin/systemctl restart mysql.service
//沒有輸出，好像成功了
//看看mysql狀態
# /bin/systemctl status mysqld.service

輸出結果：
