How to remove annoying message on Digital Ocean SSD Hosting after droplet creation

The problem. Annoying message every time you are logging in 🙂

* Documentation:  https://help.ubuntu.com/
————————————————————————————-
To finish installing WordPress, navigate to your droplet’s IP: http://xxx.xxx.xxx.xxx
Make sure to specify hostname from DO panel to your droplet before creating it (for example: ‘blog.mydomain.com’ or ‘myblog.com’)
This will create necessary Apache configs based on hostname and Apache will respond based on hostname.
Server will also respond to its IP address, so if you finish installation from http://IP then
you will need to change hostname from WordPress Settings later (from http://IP to http://hostname)
————————————————————————————-

Resolution:

You can use the GREP command to search the content in your files on your system.

-r recursive

-n line number

-w whole word matching

root@amios# grep -rnw /etc/ -e ‘To finish installing WordPress,’

That is the puppy!

File /etc/motd – Line no 2 😉
/etc/motd.tail:2:To finish installing WordPress, navigate to your droplet’s IP

Testing Cheapest SSD Hosting provider DigitalOcean – Real live testing done by myself

Please keep in mind that I cannot take responsibility to testing you are doing on your own PC using this commands.

0. Creating a Droplet which is a Linux distro with some app for example wordpress takes 55second.

0.1 Disk size on 20gb Hosting for 5 dollars is 20480MB

1. Disk Performance

root@amios:/home/ami# hdparm -t /dev/vda

/dev/vda:
Timing buffered disk reads: 614 MB in 3.00 seconds = 204.33 MB/sec

Normal drive has got speed around 50mb/s so Yes it’s an SSD drive indeed.

2. Random access test using seeker programer provided by this website http://www.linuxinsight.com/files/seeker.c

root@amios:/home/ami# gcc -O2 seeker.c -o seeker

root@amios:/home/ami# ./seeker /dev/vda
Seeker v2.0, 2007-01-15, http://www.linuxinsight.com/how_fast_is_your_disk.html
Benchmarking /dev/vda [20480MB], wait 30 seconds…………………………
Results: 7278 seeks/second, 0.14 ms random access time

0.14ms comparing on 5.5ms on normal hard drive is quite good 😉 on 7200rpm hard drive this is around 15ms

3. root@amios:/home/ami# hdparm -tT /dev/vda

/dev/vda:
Timing cached reads: 10882 MB in 2.00 seconds = 5447.41 MB/sec
Timing buffered disk reads: 864 MB in 3.00 seconds = 287.91 MB/sec

4. Another Testing using ‘dd’ command – Copying speed 2.1GB in 12second

root@amios:/home/ami# dd if=/dev/zero of=/tmp/output.img bs=8k count=256k
262144+0 records in
262144+0 records out
2147483648 bytes (2.1 GB) copied, 12.4319 s, 173 MB/s

root@amios:/home/ami# rm /tmp/output.img

5. Reading speed MB/s – different method.

root@amios:/home/ami# hdparm -t –direct /dev/vda

6. Writing speed MB/s

DO NOT FORGET CTRL+C after some time and delete the bf file.

root@amios:/home/ami# sync;time bash -c “(dd if=/dev/zero of=bf bs=8k count=500000; sync)”
^C479271+0 records in
479271+0 records out
3926188032 bytes (3.9 GB) copied, 23.3138 s, 168 MB/s

real 0m23.335s
user 0m0.360s
sys 0m14.073s

/dev/vda:
Timing O_DIRECT disk reads: 1318 MB in 3.01 seconds = 437.65 MB/sec
