安装注意几点

python-libs-2.6.6-64.el6.x86_64 conflicts with file from package python-2.6.6-36.el6.x86_64

yum install python-libs解决

yum的版本太低的话是会出现问题的

http://mirror.centos.org/centos/6/os/x86_64/Packages/yum-3.2.29-69.el6.centos.noarch.rpm

rpm –Uvh yum-3.2.29-69.el6.centos.noarch.rpm

Error:

问题：

file /usr/lib64/python2.6/zipfile.pyo from install of python-libs-2.6.6-64.el6.x86_64 conflicts with file from package python-2.6.6-36.el6.x86_64

解决：

[root@client ~]# yum install python-lib* -y

[root@client ~]# yum install salt-minion -y

问题:

Error: Package: yum-utils-1.1.30-30.el6.noarch (saltstack-repo)

Requires: yum >= 3.2.29-56

Installed: yum-3.2.29-40.el6.centos.noarch (@anaconda-CentOS-201303020151.x86_64/6.4)

yum = 3.2.29-40.el6.centos

解决:

[root@python ~]# wget http://mirror.centos.org/centos/6/os/x86_64/Packages/yum-3.2.29-69.el6.centos.noarch.rpm

[root@python ~]# rpm -Uvh yum-3.2.29-69.el6.centos.noarch.rpm

解决：估计要使用黄灯FQ或者使用国内的源
