SOLVED Change the MySQL Password
I want to explicitly document changing the password for root for MySQL without needing to re-run the installer as the Wiki suggests.
mysql_secure_installation Enter current password for root: <enter> Set root password? y New password: <new password> Remove anonymous users? y Disallow root login remotely? y Remove test database and access to it? y Reload privilege tables now? y
Then we need to change everywhere FOG references the old password without rerunning the installer.
sed -i.bak "s|snmysqlpass='<oldpassword>'|snmysqlpass='<newpassword>'|g" /opt/fog/.fogsettings sed -i.bak "s|DATABASE_PASSWORD', \"<oldpassword>\"|DATABASE_PASSWORD', \"<newpassword>\"|g" /var/www/html/fog/lib/fog/config.class.php reboot
I’m working on that second sed command’s escape sequence just now. EDIT - completed
Is there anywhere else that needs to be changed? The purpose of this is to avoid re-running the installer just for the sake of a changed MySQL password.
@sudburr In my FOG installation (1.5.5), the value for
config.class.phpis in single quotes, so the
sedstatement for needs to be:
sed -i.bak 's|DATABASE_PASSWORD', '<oldpassword>'|DATABASE_PASSWORD', '<newpassword>')|g' /var/www/html/fog/lib/fog/config.class.php
I would also like to note that the values in
.fogsettingsare only initial values for during installation. So it does not matter if you patch the password there really (not 100% sure though).

The entire process is the initial post. It’s been edited and indicated.
@sudburr cam you post the whole thing now?
Also, can we solve this?
@Tom-Elliott But that’s two steps; I’m aiming for a single step, direct solution.
And I have it now
sed -i.bak "s|DATABASE_PASSWORD', \"<oldpassword>\"|DATABASE_PASSWORD', \"<newpassword>\"|g" /var/www/html/fog/lib/fog/config.class.php
@sudburr You could try:
Then when you call it you would simply use single quotes where needed.
<?php $somepass = escapeshellarg('"\'helloworld!@@#$%^&*()\'"');
@sudburr would it be easier to write a php script to do it?
Changing the MySQL root password is contained in the command:
I’m still trying to figure out how to escape the replacement strings, since it contains both single quotes ( ’ ) and double quotes ( " ).
sed -i.bak 's|DATABASE_PASSWORD', "<oldpassword>"|DATABASE_PASSWORD', "<newpassword>")|g' /var/www/html/fog/lib/fog/config.class.php
Thought I might get to answer something on here for once! What Wayne said though is all I had to say
Don’t forget the MYSql call was going to be my one major point to not forget.
@sudburr I think those two text spots are it. Nodes do not use the root pass so no changes there.
Of course, you must issue a MYSQL command to change the password. That’s in the Troubleshoot MYSQL article for quick reference.
