Increase Disk Space with LVM
by Felix Kölzow 31 Jul '18

31 Jul '18

Dear CentOS-Community, we have a server with four hard drives that are configured as raid10 (/dev/sda). Now, /home and /root are almost full. Therefore, we decided to buy four additional hard drives that should configured also as raid 10 (/dev/sdb). I want to use LVM to extend disk space for root and home. My (successful) test procedure in a virtual environment looks like this: 1. devide /dev/sdb into /dev/sdb1 for root and /dev/sdb2 for home using parted 2. Convert disk to physical volume: pvcreate /dev/sdb1 3. add physical volume to volume group (called centos): vgextend centos /dev/sdb1 4. Allocate physical volume to a logical volume:lvextend -l +100$FREE /dev/centos/root 5. resize2fs /dev/centos/root or xfs_grows /dev/centos/root depending on file system used 6. repeat steps 2-6 for /home and sdb2 The mentioned instruction I've got from this page: https://askubuntu.com/questions/458476/adding-disks-with-lvm#459176 Now my question: Is this procedure really safe or is something missing or are there some steps which I overlooked actually? Kind Regards Felix Kölzow

Server disposal
by Kenneth Porter 28 Jul '18

28 Jul '18

Can anyone recommend a mailing list or other resource for finding a home for old server hardware? I've got a growing bone pile of retired Dell and Supermicro rack servers. I've stripped the drives and memory but hate to see the other old parts go to waste, like old RAID controllers and other proprietary parts.

Which is better? Microsoft Exchange 2016 or Linux-based SMTP Servers?
by Turritopsis Dohrnii Teo En Ming 28 Jul '18

28 Jul '18

Good evening from Singapore, I am torn between deploying Microsoft Exchange 2016 and Linux-based SMTP servers like sendmail, postfix, qmail and exim. Relative ease of installation and configuration is an important consideration factor. Microsoft Exchange 2016, Domain Controller, and Active Directory are relatively easy to install and configure. Linux-based SMTP servers are extremely difficult to install and configure and of course, extremely time-consuming. One of the features of Microsoft Exchange 2016 is that you can create additional folders on your Inbox in the server (server-side). Can Linux-based SMTP servers do that? Does Exchange 2016 offer more user-friendly features or Linux-based SMTP servers? Besides the above considerations, how about security? Traditionally, Linux is far more secure than Windows. Judging by security, Linux-based SMTP servers ought to have a higher percentage of the market share? Finally, I can only use Windows Server 2016 Standard Evaluation Copy FREE for a period of 3 years MAXIMUM. But I can use Linux servers and Mail Transport Agents (MTA) FREE perpetually. Please advise. Thank you very much. ===BEGIN SIGNATURE=== Turritopsis Dohrnii Teo En Ming's Academic Qualifications as at 30 Oct 2017 [1] https://tdtemcerts.wordpress.com/ <https://tdtemcerts.wordpress.com/> [2] http://tdtemcerts.blogspot.sg/ <http://tdtemcerts.blogspot.sg/> [3] https://www.scribd.com/user/270125049/Teo-En-Ming <https://www.scribd.com/user/270125049/Teo-En-Ming> ===END SIGNATURE===

Finding memory usage
by Bowie Bailey 27 Jul '18

27 Jul '18

I have a CentOS 7 server that is running out of memory and I can't figure out why. Running "free -h" gives me this: total used free shared buff/cache available Mem: 3.4G 2.4G 123M 5.9M 928M 626M Swap: 1.9G 294M 1.6G The problem is that I can't find 2.4G of usage. If I look at resident memory usage using "top", the top 5 processes are using a total of 390M. The next highest process is using 8M. For simplicity, if I assume the other 168 processes are all using 8M (which is WAY too high), that still only gives a total of 1.7G. The tmpfs filesystems are only using 18M, so that shouldn't be an issue. Yesterday, the available memory was down around 300M when I checked it. After checking some things and stopping all of the major processes, available memory was still low. I gave up and rebooted the machine, which brought available memory back up to 2.8G with everything running. How can I track what is using the memory when the usage doesn't show up in top? -- Bowie

C7, just updated firefox, bugs
by mark 27 Jul '18

27 Jul '18

I just updated the "critical" firefox update, and it is *seriously* buggy. 1. I killed my old session, and started a new. Many (all?) tabs show *nothing* until I put my cursor in the URL bar and hit <enter> 2. I cannot open a link in an email in thunderbird. I click the link, and after a bit (30 sec? more?) a small windows tells me that firefox is running, but not responding, which it certainly responds when I focus on firefox. mark

Problem with definition of slist in CFEngine
by Meikel 27 Jul '18

27 Jul '18

Hey folks, I have a problem with the definition of a variable of type slist in CFEngine on # uname -a ; cat /etc/redhat-release Linux policyhub.example.com 3.10.0-693.el7.x86_64 #1 SMP Tue Aug 22 21:09:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux CentOS Linux release 7.4.1708 (Core) I'm not sure if its valid to ask CFEngine questions on this mailing list, but as far as I'm running on CentOS I hope that it is okay.

Is decoupling Apache + PHP into separate nodes possible?
by Arun Khan 26 Jul '18

26 Jul '18

<preamble> I have deployed Linux/Apache/PHP (node1) + MySQL (node2) with Security Groups (AWS) or iptables controlling who can connect to the MySQL server. In topology terms -- a 2 Tier architecture. In AWS - one can deploy several such instances behind a ELB. Each LAP instance talks to a MySQL RDS. The LAP instances are either mod_php or PHP-FPM. OS -- CentOS, Ubuntu. Debian </preamble> For one of my client's end user customer, their InfoSec team is asking if Apache and the PHP application can run in separate nodes (3 Tier arch). To the best of my knowledge Apache + PHP (mod_php) have to be in the same node. With PHP-FPM it is conceivable to have Apache talk to PHP-FPM running on a separate node (see diagram https://goo.gl/xTfbjg) But I have not done it myself and I am not sure if it is feasible. If it is feasible then what's the best practice to distribute the *.html *.css and *.php files between the Apache + the PHP-FPM nodes and how to achieve load balance between Apache and PHP-FPM nodes. I have searched but not found any reference setups. Would appreciate suggestions / references from anyone who has done a 3 Tier Apache + PHP + MySQL deployment in production. Thanks in advance. -- Arun Khan "Everyone has an expiration date"

Do this, logged onto the mailserver. telnet localhost 25 helo mydomain.com (substitute a valid domain here) mail from: <someuser(a)validdomain.com> rcpt to: <youremailaddress(a)yourdomain.com> data From: someuser(a)validdomain.com to: youremailaddress(a)yourdomain.com subject: test This is a test mesage . note: blank line between mail headers and body end data with line containing only '.'. Then check your maillog and send the output to the list.
