Using environment variables in mariadb
by Robert Moskowitz 04 Apr '17

04 Apr '17

I want to script a rather simple create database operation. Thing is, I have to provide the password for that database. I would like to do this with an environment variable, but the simple approach dose not work: mailpswd=charlie mysql -u root -p CREATE DATABASE mailfix; CREATE USER 'mailfix'@'localhost' IDENTIFIED BY $mailpswd; GRANT ALL PRIVILEGES ON `mailfix` . * TO 'mailfix'@'localhost'; Of course the mysql command needs the mysql root password, but that is as expected. But mysql will not process $mailpswd, not surprisingly. I know I could create a file with these commands, sed the password into the file, then pipe thr file into mysql. I would rather do this directly without a temp file. thanks

How to enable the svm cpu flag inside a vm?
by Leonard den Ottolander 03 Apr '17

03 Apr '17

Hello, I'm trying to get the Android Emulator to run inside a kvm vm on CentOS-6. Apparently the latest Android Emulators cannot run without hardware acceleration so I am trying to get the vm to see the svm cpu flag. Host: $ grep model\ name /proc/cpuinfo | sort -u model name : AMD Phenom(tm) II X4 965 Processor $ grep svm /proc/cpuinfo | sort -u flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm 3dnowext 3dnow constant_tsc rep_good nonstop_tsc extd_apicid pni monitor cx16 popcnt lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs skinit wdt npt lbrv svm_lock nrip_save $ cat /sys/module/kvm_amd/parameters/nested 1 I have tried copying the cpu options (Opteron_G3) in the host cpu configuration and setting the svm flag to either "model", "required" or "force" to no avail: $ ps waux | grep qemu qemu 7962 7.2 21.9 3722092 2680668 ?

Sendmail is considered deprecated
by Xinhuan Zheng 02 Apr '17

02 Apr '17

Hello, Today I searched redhat official portal and learned that Sendmail is considered deprecated. By default, CentOS 7 will use postfix as MTA. I need good advise on what it means to us. We are CentOS customers. We use that operating system for quite a few years. We rely on Sendmail for years for us to relay large quantity of emails to our customers for marketing purpose. We build our additional fallback servers as well for fallback relays. We build our customized configuration for Sendmail too. I really need help to figure out if we can continue using Sendmail (even deprecated) for future long term and what implication would be doing so. Thanks, - xinhuan

by Robert Moskowitz 31 Mar '17

31 Mar '17

Is there an Apache tool to manage firewalld on a headless server? I am looking forward to my next Centos project which is to replace my Juniper SSG5 firewall... And along that line, what overlap, if any between firewalld and Suricata? thank you

have udev to ignore/hide a scsi disk - but how?
by lejeczek 30 Mar '17

30 Mar '17

hi everyone I've been playing and trying to tell udev to ignore and not create symlinks in /dev but I fail. Hoping this is the one: ENV{ID_SERIAL}== I've tried: ENV{SYSTEMD_READY}:="0" OPTIONS+="last_rule" even ENV{UDISKS_IGNORE}="1" but udev tests would still show: ACTION=add and symlinks created. Would share an advice? many thanks, L.

Python 3.x on Centos 7
by Matt 29 Mar '17

29 Mar '17

Is there a way to install Python 3.x on Centos 7.x without breaking anything that depends on an older version of Python? This server is a minimal Centos 7 install that primarily runs a simple LAMP setup.

If you enable the CR repo on your 6.x machine I believe you'll see these updates, and can install them if you want to check things out. My experience is that there will likely be a few updates from the CR when the production set is released. If you go to: http://mirror.centos.org/centos/6.8/cr/<i386|x86_64>/Packages/ you'll see that there are packages for both 32- and 64-bit, so you should be getting 32-bit updates that will take you up to 6.9.
