The default paths to install Apache PHP Mysql

[walkerf]

Generally, under what paths Apache PHP Mysql are installed? and How do I know if these three are installed or not on the machine, Thanks for help!

after that,
run command

you can find startup script of apache
run command

you can find startup script of mysql

I ran "locate mysqld_safe", it's ok but the following is wrong.


root@ubuntu:/usr/bin# locate mysqld_safe
/usr/bin/mysqld_safe
/usr/share/man/man1/mysqld_safe.1.gz

but when I cd into /usr/bin and want to ls myslqd_sage, I got
root@ubuntu:/usr/bin# ls mysql-safe
ls: cannot access mysql-safe: No such file or directory

Why there isn't mysql-safe in /usr/bin?
