In the lifecycle before_install, i added the following line of command.
sudo echo "127.0.0.1 db.test.mysql" >> /etc/hosts
however, i ran into the error saying “Permission denied”. So is there anyone knowing how to fix it?
btw, i also added sudo: required
, and there were not any other special configs but a few mysql scripts.
appreciate all the help. tks
In general, I suggest testing commands in the most basic form before you put it in your configuration.
On your machine, you will know that sudo
would not work this way; sudo
only invokes the command echo
, but the I/O redirection with >>
is used by the shell, which only has the user privilege. You need to write to the file with the root privilege; e.g.,
echo "127.0.0.1 db.test.mysql" | sudo tee -a /etc/hosts
Or, you can use the “hosts” addon. https://docs.travis-ci.com/user/hosts/
