RHEL6下獲取安裝包(RPM)而不安裝的方法

有時候我們只能在某個機器上網獲得RPM安裝包，如何將RPM包在不能上網的內網機器安裝，就需要能將安裝包下載到本地而不安裝，然後再把這些包複製到內網機器，進行安裝。另外一個方法是建立映象伺服器，沒有測試！下面開始實驗，以安裝saltstack(salt-master和salt-minion)為例。

1) 首先在能上外網的機器上設定好yum源。我的RHEL6.4已經設定了幾個yum源，如下：

[rhel6_4-default]
name    = "Red Hat Enterprise Linux Server release 6.4 (Santiago)"
baseurl  = ftp://192.168.122.100/pub/rhel64
enabled  = 1
gpgcheck = 1
gpgkey  = 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_64
name    = Cloudera's Distribution for Hadoop, Version 5
enabled  = 1
gpgcheck = 1
baseurl  = 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_64
name    = Cloudera's GPLExtras, Version 5
enabled  = 1
gpgcheck = 1
baseurl  = 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_64
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=http://ftp.linux.ncsu.edu/pub/epel/RPM-GPG-KEY-EPEL-6

為獲取saltstack安裝包，需要增加下面的yum源：

****安裝rpmforge
****這步很重要，在redhat 6和centos 6的epel源上沒有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，需要的源準備齊全。開始安裝外掛yum-plugin-downloadonly.noarch 0:1.1.30-14.el6:

# yum install yum-downloadonly

安裝完畢之後，這台機器就可以下載但是不安裝saltstack的RPM包了。

# mkdir /root/Downloads/salt-minion
# mkdir /root/Downloads/salt-master
# mkdir /root/Downloads/salt-ssh
# 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-ssh salt-ssh        #### minion上不需要安裝任何salt,直接在master通過ssh.
# yum install -y --downloadonly --downloaddir=/root/Downloads/salt-api salt-api        #### rest api of salt

2) 把/root/Downloads/salt-minion下面的rpm複製到其他機器上，然後安裝:

# 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

同樣的可以安裝salt-master.
