Installing Postgres in Fedora Core 10 and Setting of default password

Lately, I was trying to install a new postgresql server in my FC10 box. I thought it was as easy as 1,2,3 but I discovered it needed some technical knowledge to install postgresql server.

After reading few blogs and my personal google docs, I came up with the following procedure.

Installing postgresql server
- Go to System -> Add/Remove Software
- Search for postgresql
- install postgresql-server and postgresql client files
- after installation, you have to initialize your database
- open terminal
- su root
- su postgres
- cd ~
- initdb data
- then start postgresql server with pg_ctl -D data -l logfile start

Setting default password for user postgres
- without exiting the terminal or su postgres, type
psql -c "ALTER USER postgres WITH PASSWORD 'password'" -d template1

that's it for now....

Changing/setting default mysql root password

Changing/setting default mysql root password:

mysqladmin command to change root password

If you have never set a root password for MySQL, the server does not require a password at all for connecting as root. To setup root password for first time, use mysqladmin command at shell prompt as follows:

$ mysqladmin -u root password NEWPASSWORD

However, if you want to change (or update) a root password, then you need to use following command

$ mysqladmin -u root -p'oldpassword' password newpass

For example, If old password is abc, and set new password to pass, enter:

$ mysqladmin -u root -p'abc' password 'pass'

Installing flash player in fedora core 10

For 32-bit machines, run the following commands:

- sudo rpm -ivh http://linuxdownload.adobe.com/adobe-release/adobe-release-i386-1.0-1.noarch.rpm
- sudo yum install flash-plugin

Then restart firefox. You should have a working flash player by then.

For 64-bit machines, (e.g. my 64-bit AMD machine), i followed the following steps:
- Download the file http://download.macromedia.com/pub/labs/flashplayer10/libflashplayer-10.0.22.87.linux-x86_64.so.tar.gz (3.56 MB)

Extract libflashplayer.so and copied it into
- /usr/lib64/mozilla/plugins/libflashplayer.so

GD library and mod_rewrite issue in Fedora Core 10 (with file permission issues on htaccess and _config.php)

GD Library not Installed:

Lately, I was trying to install silverstripe CMS in my local machine. I have this warning that GD library is not enabled. The simplest thing to do to solve this problem is install GD. Good thing I about fedora core 10 is I no longer have to go to the terminal for simple install/uninstall. So, I just click on System->Add remove Software, then type GD in the search box of the window that appeared.

I just checked(selected) "A module for PHP Applications using GD" , then clicked apply. The installer then will do the rest for you like checking for dependencies, downloading etc.

Then, go to System->Services then restart httpd. Then GD should be installed in your system by now.

Enable Mod_rewrite in Fedora Core 10
Aside from the GD library problem, I encountered also another problem during my Silverstripe installation.

"Friendly URLs are not working. This is most likely because mod_rewrite isn't configuredcorrectly on your site. Please check the following things in your Apache configuration; you may need to get your web host or server administrator to do this for you:

• mod_rewrite is enabled
• AllowOverride All is set for your directory"

To solve this problem, I have to edit the httpd.conf file. In FC10, it is located in /etc/httdp/conf folder.
edit the httpd.conf file using vi, nano or gedit or any text editor of your choice.
Then, remove the # sign in
LoadModule rewrite_module modules/mod_rewrite.so line.
Then change
AllowOverride None to AllowOverride All
Then don't forget to restart the httpd service.

After solving those problems, I then have a working silverstripe installation in my box. Now, I'm off to exploring silverstripe CMS.....

* If you are having issues on .htaccess and _config.php files, like you have to make it writeable. Then after chmod 777 you still get the same warning, one quick solution to that is set SELinux to permissive.
