Only one of which belongs to cassandra, as I have a few java processes

Hey all, There's a website I help run that uses the Cassandra DB as its database. I notice that if I run the web server in SELinux permissive mode, the site works fine. But if I put it into enforcing mode, the site goes down with this error: Warning: require_once(/McFrazier/PhpBinaryCql/CqlClient.php): failed to open stream: Permission denied in

Hey all, I'm trying to learn how to use some of the big data stores. Specifically I want to learn how to use CassandraDB and Hadoop. Originally I'd had the idea of trying to setup a cassandra ring on the Amazon AWS free tier. However it seems that neither will run on a t2.micro instance. So I was wondering.. what are some really cheap VPS services that you like to use for one off

Hey guys, Apologies in advance if this question is in poor taste. But I've really fallen in love with learning about the cassanrdra database. The only problem is that it doesn't run very well on an t1.micro instance at amazon and the larger sizes are quite expensive. An m1.small can do the trick, while still not optimal. So I was wonder if there was any real value in the cloud or even

Hey guys, I'm trying to echo my password into some commands inside of a bash script. But I think I'm going about it incorrectly. Here's the top part of my script: #!/bin/bash pub="~/.ssh/id_rsa.pub" dps_pass="my_pass" ssh="/usr/bin/ssh" scp="/usr/bin/scp" for i in 10.10.10.2{5,6} do echo "xfring key up" echo $dps_pass | $scp $PUB

However it's not an RPM from a repo. I downloaded the rpm from the appdynamics site itself.

Hello, I discovered today that CentOS 7 has replaced MySQL with MariaDB. Which is fine, it's seems really similar. And I was already aware that it was written by the original team that wrote mysql. It's cool that the mysql command still gets you in! This is the version I have: [root at web1:~] #mysql --version mysql Ver 15.1 Distrib 5.5.37-MariaDB, for Linux (x86_64) using readline

Hey guys, I've got another C7 problem I was hoping to solve. I installed appdynamics-php-agent-4.0.5.0-1.x86_64 on a C7.1 host. It's failing to communicate with it's controller on another host. And this is the interesting part. Whether or not I have SELinux enabled, I have apache reporting SELinux problems. [root at web1:~] #getenforce Permissive May 10 20:47:56 web1 python[25735]:

Hey all, I just got around to trying out CentOS 7. And for some reason when I attempt to install mysql-server, instead I'm offered mariadb? I'm using epel and remi as my repos. [root at web1:/etc/yum.repos.d] #cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.0 (Maipo) [root at web1:/etc/yum.repos.d] #yum repolist Loaded plugins: amazon-id, rhui-lb repo id

Well, I was having a heck of a time with the rpm install in terms of customizing the install directory. So I thought the easy way out might be to go for a source install. Which I tried and this was the output from the install: [root at web1:/opt/AppDynamics/appdynamics-php-agent] #./install.sh appd.jokefire.com 443 beta.jokefire.com "Web Front End" web1.jokefire.com Install script for

Hey all, I just unstalled MariaDB version 10 from the mariadb repositories under a CentOS 7 host. The install went fine! [root at nfsdb1 ~]# rpm -qa | grep -i mariadb MariaDB-common-10.0.19-1.el7.centos.x86_64 MariaDB-server-10.0.19-1.el7.centos.x86_64 MariaDB-client-10.0.19-1.el7.centos.x86_64 MariaDB-shared-10.0.19-1.el7.centos.x86_64 However, when I go to start up the service, I'm

Yeah dude, exactly. Except I actually do want to start using it. I've been disabling SELINUX forever

Hey Jeremy, > Have you tried changing the folder where it's writing into with these > lables? httpd_sys_content_rw_t or httpd_user_content_rw_t Adding 'rw' to the command did the trick. I tried httpd_sys_content_rw_t and that works fine! Thanks for the tip! Tim On Thu, Jan 22, 2015 at 1:19 PM, Jeremy Hoel <jthoel at gmail.com> wrote: > Have you tried changing
