how to execute init scripts from the command line using ssh

ssh -t user@server1 "ls -al /root/test/"

Above mentioned code works fine and displays all the contents of the test directory folder but this code fails

ssh -t user@server1 "/etc/init.d/mysql start"

It does not start the mysql server, I have login in to server and use the same command to start the mysql server

Can any one explain this behaviour ? what I am doing wrong bit puzzled 🙁

Answer

Do something like this:

ssh user@hostname "/etc/init.d/mysql start < /dev/null > /tmp/log 2>&1 &"

ssh needs to use stdin and stdout to interact. This will allow it to do that and redirect the output to somewhere useful.
