Install Mariadb on Centos 7 fails
by david 23 Sep '16

23 Sep '16

Folks I'm having problems installing Mariadb in Centos 7. Here's what I did: 0) Become root 1) Make sure that mariadb and mysql are NOT installed. 2) Delete residual libs rm -rf /var/lib/mysq* 3) yum install -y mariadb-server installed mariadb-5.5.50-1.el7_2.x86_64 from the Centos 'updates' repository 4) systemctl start mariadb 5) systemctl status mariadb All works well until step 5, where I get the result: # systemctl status mariadb ? mariadb.service - MariaDB database server Loaded: loaded (/usr/lib/systemd/system/mariadb.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Thu 2016-09-22 17:46:38 PDT; 4min 3s ago Main PID: 16261 (code=exited, status=1/FAILURE) Sep 22 17:46:37 goat.xxx.com mysqld_safe[16261]: /usr/bin/mysqld_safe: line 139: /var/log/mysqld.log: Permission denied Sep 22 17:46:37 goat.xxx.com mysqld_safe[16261]: /usr/bin/mysqld_safe: line 183: /var/log/mysqld.log: Permission denied Sep 22 17:46:37 goat.xxx.com mysqld_safe[16261]: touch: cannot touch `/var/log/mysqld.log': Permission denied Sep 22 17:46:37 goat.xxx.com mysqld_safe[16261]: chown: cannot access `/var/log/mysqld.log': No such file or directory Sep 22 17:46:37 goat.xxx.com mysqld_safe[16261]: chmod: cannot access `/var/log/mysqld.log': No such file or directory Sep 22 17:46:37 goat.xxx.com systemd[1]: mariadb.service: main process exited, code=exited, status=1/FAILURE Sep 22 17:46:38 goat.xxx.com systemd[1]: mariadb.service: control process exited, code=exited status=1 Sep 22 17:46:38 goat.xxx.com systemd[1]: Failed to start MariaDB database server.

Hint: Some lines were ellipsized, use -l to show in full. [root@goat ~]# My environment is a Centos 7 installation running as a VM inside Vmware, and is not a production system. It is updated nightly. When I examined the files alluded to, /var/log/mysqld.log does not exist but /var/log/mariadb/mariadb.log exists and is empty. Adivce would be appreciated Thanks David

OT: Areca ARC-1220 compatible with SATA III (6Gb/s) drives?
by Robert Arkiletian 23 Sep '16

23 Sep '16

Running C6 fileserver. Want to replace 7 year old HDs connected to an Areca ARC-1220 raid sata II (3Gb/s) controller. Has anyone used this controller with newer 2TB SATA III (6Gb/s) WD Re drives like the WD2000FYYZ or the WD2004FBYZ?

Firefox 45.4.0-1 for CentOS-6 and CentOS-7
by Johnny Hughes 23 Sep '16

23 Sep '16

The Red Hat engineers disabled the ffmpeg capability of firefox a couple releases back due to stability issues. CentOS also has removed it as for our main repositories, we build the source code for RHEL with as few changes for branding/artwork as we can. That said, we (I :D) want a firefox with ffmpeg support available, therefore I have created a centosplus version of firefox that has ffmpeg enabled starting with version 45.4.0-1, released to the repositories a few minutes ago. You can get it from the CentOS Plus Repository: https://wiki.centos.org/AdditionalResources/Repositories/CentOSPlus Now that we are maintaining a CentOSPlus Firefox .. if there are other things people want compiled into Firefox that are configure options and you are creating/compiling a new firefox, please use the CentOS-Devel mailing list to discuss this with me and we can try to roll those things into the CentOS Plus version of Firefox. Since CentOS-5 is End Of Life in about 6 months, I don't plan to add a Firefox to CentOS Plus there unless there are many who absolutely need it. Thanks, Johnny Hughes

CentOS 6.8, Iptables 1.4.7, and MASQUERADE
by Robert Heller 21 Sep '16

21 Sep '16

I have a server that is also a firewall router at a public library with a fiber optic Internet connection. It is running kernel 2.6.32-642.4.2.el6.x86_64 (current CentOS 6.8) and Iptables 1.4.7 (current stock CentOS 6.8). I having trouble with Internet throughput. I am supposed to be getting 20Mbits down and 20MBits up, but I am not getting that. It has no problem doing 20MBits down, but for uploads of *large* files (using different protocols, such as ssh or http), the upload starts at 20MBits, but over time quickly slows down to about 3MBits. Speedtests claim I am getting about 20/20. I seem to be about to get 3Mbits *per transfer*, even if the transfers are concurrent and MRTG shows total throughput edging up to 6Mbits. What can possibly be going on. My ISP is not believing there is anything wrong on their end. About the only thing left is maybe some sort of weirdness with Iptables imposing some sort of I/O overhead, maybe related to the MASQUERADE postrouting. Does this even make sense? -- Robert Heller -- 978-544-6933 Deepwoods Software -- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services heller(a)deepsoft.com -- Webhosting Services

ipset and blacklisting

This is what ipset can do for traffic on a home server that's not wanted on a slow 6MB DSL connection. http://palmettoshopper.com/httpd_traffic.jpg I only use my home server for zoneminder, testing my commercial website and streaming movies. Got tired of hackers looking for files that don't exist on my home server and non-complying robots. Check the drop in bandwidth. Setup up a redirect to the NSA webite. They can deal with the hackers.

OT: I fixed and it wasn't broken
by TE Dukes 21 Sep '16

Hello, I fixed it real good. I bought a Lenovo TS130 ThinkServer about 5 or 6 years ago. Folks told me, RHEL/CentOS would not run on this server. I bought it and installed it and it works fine. So, a couple weeks ago, I decided to upgrade the memory. At the time, the bios only supported 16GB but it would be upgradable to 32GB. So, I started adding memory and figured I needed to upgrade the bios so I could get to 32GB. I got through 2 updates with rufus 2.11 and FreeDOS. Both installed with no problems. On the third upgrade, my USB flash drive is no longer recognized as a boot device. The fourth bios upgrade is a shell script run from RHEL which the support was also added later. I tried that first but it didn't work. Didn't get any errors, it just didn't work. Lenovo says use rufus 2.2 which supports MS-DOS. I can't get that version to create a bootable USB drive. It fails. I have tried .iso images and adding the bios files to it for a bootable DVD/CD. It boots but can't find the bios files. A dir of the DVD shows the flash.bat. I've tried plopt and a couple others. I'm stuck!! Any help would be greatly appreciated.

CM8828 sound chip ??
by Alice Wonder 20 Sep '16

Need a PCI-E sound card with low profile bracket, optical out, and one of those mini-din connectors that fans out into various analog connectors. Only card I have been able to find so far uses a CM8828 chipset. Looks like that chipset is natively supported by the kernel alsa driver starting in 3.17 kernel but CentOS 7 uses 3.10 kernel. I did not see a package that was obviously for that chipset in elrepo. Has that driver been backported into the RHEL/CentOS 7 kernel, and if not, is it in elrepo? Worst case scenario I suppose it may be possible to port the driver like many of the elrepo drivers have been, but not sure I want to buy hardware based on a "may be possible" Thanks for any comments. -- -=- Sent my from my laptop, may not be able to respond timely
