I have RedHat Enterprise Linux Server 7, and I downloaded the linux kernel version 4.12.10 which I am trying to compile but when I execute the following command: make modules I get the following error: scripts/sign-file.c:25:30: fatal error: openssl/opensslv.h: No such file or directory Does anyone have an idea to fix this please ? To fix this problem, you have to install OpenSSL development package, which is available in standard repositories of all modern Linux distributions. To install OpenSSL development package on Debian, Ubuntu or their derivatives: $ sudo apt-get install libssl-dev To

I used this procedure to install Jenkins: https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+RedHat+distributions After it was up and running I discovered the /var/lib/jenkins partition on my server is very small. I want to move it, but I do not want to change the user that it runs under. I am new to Linux and I'm stumped. How do I move it for example to my Home/Public folder? The "Jenkins" user doesn't seem to have a Home folder. Its running as a daemon on startup, so I have no idea where to configure those settings. Can I create a Home folder for the Jenkins user? How? I read

Is it possible to set the maximum number of open files to some "infinite" value or must it be a number? I had a requirement to set the descriptor limit for a daemon user to be "unlimited" and I'm trying to determine if that's possible or how to do it. I've seen some mailing lists refer to a "max" value that can be used (as in: "myuser hard nofile max", but so far the man pages and references I've consulted don't back that up. If I can't use 'max' or similar, I'd like to know how to determine what the max number of files is (theoretically) so I have some basis for whatever number I pick. I don

I am a bit confused by the fact that although I installed RHEL 5.1 from DVD (RedHat/5.1.x86_64), when I issue command: cat /etc/redhat-release I got: Red Hat Enterprise Linux Server release 5.5 (Tikanga) What does this mean? is this to be the release version or kernel version? Is there another way to confirm the real version of RHEL? I am asking this question because there will be certain applications that would depend on this. Many thanks in advance. I assume that you've run yum upgrade. That will in general update you to the newest minor release. Your main resources for determining the

做过好多次CentOS的yum源配置了，这里总结一下： CentOS和Redhat的区别在于，CentOS是基于redhat的社区版，免费，跟Redhat对应，但是release比redhat慢。 Redhat的yum是非免费服务，而CentOS的yum是免费的，所以一般我们在Redhat上配置和CentOS的yum源。 升级环境：Redhat linux 5.11，这台机器是(bugzilla+svn+svnmanager+scmbug)的测试环境，刚刚由5.6升级而来。升级后perl的版本还是5.8，而bugzilla需要5.10的版本，而单独升级perl会产生一连串的系统包依赖，所以必须使用yum的方式来处理。 [root@subv2 yum.repos.d]# rpm -qa|grep yum yum-3.2.22-40.el5 yum-metadata-parser-1.1.2-4.el5 yum-security-1.1.16-21.el5 yum-rhn-plugin-0.5.4.1-7.el5 yum-updatesd-0.9-6.el5_10 [root@subv2 yum.repos.d]# 需要重装yum软件，卸载redhat上的yum软件，安装centos的yum软件。 这里配置163的yum源： http://mirrors.sohu.com/centos

I tried to use PIL to do some JPEG work in my django app with PIL but I'm getting this IOError.. not sure what to do. ""decoder jpeg not available"" Am I missing the JPEG decoder from my server? If so, how do I fix it? You need to install jpeg library first and reinstall your PIL. For example, I'm using CentOS, to install libjpeg, I run sudo yum install -y libjpeg-devel It depends on what kind of linux you are using. And here you have to remove the old PIL rm -rf /usr/lib/python2.6/site-packages/PIL-1.1.7-py2.6-linux-x86_64.egg/ Then install the PIL sudo easy_install PIL I have found this
