大佬教程收集整理的这篇文章主要介绍了无法在CentOS 7上安装Varnish，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
我首先添加了这些rpm：
sudo rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/jemalloc-3.6.0-1.el6.x86_64.rpm sudo rpm -iUvh http://195.220.108.108/linux/centos/7.0.1406/extras/x86_64/Packages/epel-release-7-2.noarch.rpm yum install varnish
但我明白了：

在干净的CentOS 7系统上,您可以通过以下方式安装Varnish 4：
yum install epel-release yum install varnish
由于您的系统不再干净,您必须先清理它.特别是：
>您安装了EL6的jemalloc软件包.您需要将其替换为EL7.由于您已经安装了EPEL repo,因此应该足够：
yum update jemalloc
否则只需删除并重新安装即可.
rpm --nodeps -e jemalloc yum install jemalloc
>您从某个地方(可能是Varnish Community)安装了名为varnish-4.0的存储库,但您没有提到这一点.你需要删除它,因为(a)它只用于EL6,(b)EPEL已经发布了Varnish 4.
rpm --nodeps -e $(rpm -qf /etc/yum.repos.d/varnish*.repo)
yum install varnish
最后一点：EPEL Varnish将追溯EPEL’s enterprise QA requirements上游的Varnish点发布.如果跟踪点发布对您很重要,您可能希望参加EPEL中此包的QA process.这通常涉及构建或安装测试包,然后根据它是否有效来执行voting it up or down. (例如,在撰写本文时,Varnish 4.0.2是最新的上游版本,它需要另外3个upVotes才能在EPEL中升级到稳定版.)
