RHEL6下获取安装包(RPM)而不安装的方法

RHEL6下获取安装包(RPM)而不安装的方法有时候我们只能在某个机器上网获得RPM安装包，如何将RPM包在不能上网的内网机器安装，就需要能将安装包下载到本地而不安装，然后再把这些包复制到内网机器，进行安装。另外一个方法是建立镜像服务器，没有测试！下面开始实验，以安装saltstack(salt-master和salt-minion)为例。1) 首先在能上外网的机器上设置好yum源。我的RHEL6.4已经设置了几个yum源，如下：[rhel6_4-default]name = "Red Hat Enterprise Linux Server release 6.4 (Santiago)"baseurl = ftp://192.168.122.100/pub/rhel64enabled = 1gpgcheck = 1gpgkey = ftp://192.168.122.100/pub/rhel64/RPM-GPG-KEY-redhat-release[cloudera-cdh5]# Packages for Cloudera's Distribution for Hadoop, Version 5, on RedHat or CentOS 6 x86_64name = Cloudera's Distribution for Hadoop, Version 5enabled = 1gpgcheck = 1baseurl = ftp://192.168.122.100/pub/cloudera/cdh/5/gpgkey = ftp://192.168.122.100/pub/cloudera/cdh/RPM-GPG-KEY-cloudera[cloudera-gplextras5]# Packages for Cloudera's GPLExtras, Version 5, on RedHat or CentOS 6 x86_64name = Cloudera's GPLExtras, Version 5enabled = 1gpgcheck = 1baseurl = ftp://192.168.122.100/pub/cloudera/gplextras/5/gpgkey = ftp://192.168.122.100/pub/cloudera/gplextras/RPM-GPG-KEY-cloudera[epel-6]name=Extra Packages for Enterprise Linux 6# http://ftp.linux.ncsu.edu/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm#baseurl=http://ftp.linux.ncsu.edu/pub/epel/6/x86_64failovermethod=priorityenabled=1gpgcheck=1gpgkey=http://ftp.linux.ncsu.edu/pub/epel/RPM-GPG-KEY-EPEL-6为获取saltstack安装包，需要增加下面的yum源：****安装rpmforge****这步很重要，在redhat 6和centos 6的epel源上没有python-jinja2. # wget --no-check-certificate http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm # rpm -Uvh rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm好了，需要的源准备齐全。开始安装插件yum-plugin-downloadonly.noarch 0:1.1.30-14.el6:# yum install yum-downloadonly安装完毕之后，这台机器就可以下载但是不安装saltstack的RPM包了。# mkdir /root/Downloads/salt-minion# mkdir /root/Downloads/salt-master# mkdir /root/Downloads/salt-api# yum install -y --downloadonly --downloaddir=/root/Downloads/salt-minion salt-minion# yum install -y --downloadonly --downloaddir=/root/Downloads/salt-master salt-master# yum install -y --downloadonly --downloaddir=/root/Downloads/salt-api salt-api #### rest api of salt2) 把/root/Downloads/salt-minion下面的rpm复制到其他机器上，然后安装:# scp -r /root/Downloads/salt-minion root@anotherIP:~/# ssh root@anotherIP# cd ~/salt-minion# rpm -ivh *.rpm############################################### service salt-minion start#### service salt-master start #### service salt-api start同样的可以安装salt-master.
