1、使用systemctl命令
systemctl status mysqld
這個命令會顯示MySQL服務的詳細信息，包括服務名稱，在輸出的信息中，找到Active: active (running)這一行，其中的mysqld就是MySQL服務名稱。
2、使用ps命令
ps -ef | grep mysqld
這個命令會列出所有包含mysqld的進程，在輸出的信息中，可以看到進程名就是MySQL服務名稱。
3、查看/etc/init.d目錄下的腳本
ls /etc/init.d/ | grep mysql
這個命令會列出/etc/init.d/目錄下的所有以mysql開頭的腳本，通常情況下，這些腳本都是MySQL服務的啟動和停止腳本，其中的腳本名就是MySQL服務名稱。
4、查看/lib/systemd/system目錄下的配置文件
ls /lib/systemd/system | grep mysql
這個命令會列出/lib/systemd/system目錄下的所有以mysql開頭的配置文件，通常情況下，這些配置文件都是MySQL服務的配置文件，其中的文件名就是MySQL服務名稱，如果有一個名為mysql.service的文件，那么這個文件對應的MySQL服務名稱就是mysql。
