http://www.mydomain.com/cron.php?cron=do&day=15

This cron works fine from the browser. However, when I use this command through wget:

/usr/bin/wget –delete-after http://www.mydomain.com/cron.php?cron=do&day=1

it end up with cron.php?cron=do

http://www.mydomain.com/cron.php?cron=do

After doing a research, I found the solution. I need to escape the ? and the & and it works like a charm.

/usr/bin/wget –delete-after http://www.mydomain.com/cron.php\?cron=do\&day=1

Or enclose the URL in single quotes like this:

/usr/bin/wget –delete-after ‘http://www.mydomain.com/cron.php?cron=do&day=1′

To fix this, you need to create or update mlocate database, a database used by locate. Simply execute updatedb command:

$ updatedb

Now you can continue with locate commands as normal.

updatedb command will creates or updates a database at ‘/var/lib/mlocate/mlocate.db’ which locate uses to find a files.

Below are instructions on how to install webmin control panels on your VPS or Dedicated Server:

1) Connect SSH to your server and type the following command:

Create new temporarily folder:
# mkdir tmp

Change to temporarily folder:
# cd tmp

Download webmin:
# wget http://sourceforge.net/projects/webadmin/files/webmin/1.xxx/webmin-1.xxx-1.noarch.rpm

(Replace xxx with the corresponding Webmin version)

Once the file has been downloaded, enter this command, this will install Webmin and all its dependencies:

# rpm -ivh webmin-1.xxx-1.noarch.rpm

Now you can login to your newly install webmin control panel at server IP address at port 10000. So if your server IP address is 123.123.123.123 then your webmin address is:

https://123.123.123.123:10000

Login to Webmin as root using your password.

1) Login to your Kloxo panel securely using SSL

2) Click on the “DNS Templates” icon from the home screen.

3) You will be presented with the following screen, click on Add DNS Template

4) Add settings in your DNS template box. Enter your Primary and Secondary DNS with ns1.yourdomain.com and ns2.yourdomain.com (see below).

5) Click Add button

Finally, you now need to create / register the name servers at your domain registrar. Log in to your domain registrar and edit the assigned nameservers so that it now points at your new nameserver names (ns1.yourdomain.com, ns2.yourdomain.com). Please contact your registrar to assist you.

# yum install mysql-server

But I keep getting the same error, here is the result:

# yum install mysql-server
Setting up Install Process
Setting up repositories
Cannot find a valid baseurl for repo: update
Error: Cannot find a valid baseurl for repo: update

I figured out that my DNS is not working. There is no response to www.centos.org.

# ping www.centos.org
ping: unknown host www.centos.org

Not only Centos website, it also can’t recognize any domain name. As a solution, I’ve to set up new domain name server (DNS) in my machine by add the following line to /etc/resolv.conf:

nameserver 8.8.8.8
nameserver 8.8.4.4

Save and close the file. Done! Now I just added primary and secondary dns server in my machine. To check if the machine work fine, I type ping www.centos.org. It has a reply, means it work well. So, I tried yum command again and all is working.

Hopefully this will help someone else.

# rpm -qa | grep mysql

Check the output list:

mysqlclient10-3.23.58-4.RHEL4.1
libdbi-dbd-mysql-0.6.5-10.RHEL4.1
mysql-4.1.20-1.RHEL4.1
mysql-devel-4.1.20-1.RHEL4.1

If mysql-server* package is not on the list, means you haven’t installed the mysql-server package.

To start install MySQL Server, do the following command (Yum must be installed):

# yum install mysql-server

Once the installation is complete, recheck the package again:

# rpm -qa | grep mysql

mysqlclient10-3.23.58-4.RHEL4.1
libdbi-dbd-mysql-0.6.5-10.RHEL4.1
mysql-4.1.20-3.RHEL4.1.el4_6.1
mysql-devel-4.1.20-3.RHEL4.1.el4_6.1
mysql-server-4.1.20-3.RHEL4.1.el4_6.1

Now start MySQL server daemon:

# service mysqld start

Untuk memeriksa IP Forwading, gunakan arahan:

# sysctl net.ipv4.ip_forward net.ipv4.ip_forward = 0

Atau:

# echo 1 > /proc/sys/net/ipv4/ip_forward

Untuk mengaktif IP forwarding, sunting /etc/sysctl.conf dan tambah:

net.ipv4.ip_forward = 1

Untuk mengetahui hostname semasa taipkan arahan:

# hostname

Untuk mengetahui FQDN dalam sistem, gunakan arahan:

# hostname --fqd

Untuk menukar hostname, guna arahan:

# hostname NAMA_BARU

# aptitude install sudo

Fail configuration terletak di /etc/sudoers
