Regarding the following command and result:
$ systemd-analyze blame | grep -P '(mysql|php|apache)' 12.936s mysql.service 8.815s php7.0-fpm.service 6.515s apache2.service
I want to remove LAMP from startup so my system boot faster. Since I don't use LAMP all the time, I would prefer to run them whenever I need rather than keeping them running all the time, especially during boot.
I have checked some other questions here (including How to stop mysql from running at boot time? and how to stop apache2, mysql from starting automatically as computer starts? both asked in 2011) But all of them are old.
Is there any difference between using those method and the way it should be done in 16.04? (the reason I ask this question is as far as I know, Ubuntu has moved towards Systemd which was not the case at 2011!)
