首先配置Tor Repository
[root@web1 ~]#vi /etc/yum.repos.d/tor.repo
内容如下：
[tor]
name=Tor repo
enabled=1
baseurl=https://deb.torproject.org/torproject.org/rpm/DISTRIBUTION/$basearch/
gpgcheck=1
gpgkey=https://deb.torproject.org/torproject.org/rpm/RPM-GPG-KEY-torproject.org.asc
[tor-source]
name=Tor source repo
enabled=1
autorefresh=0
baseurl=https://deb.torproject.org/torproject.org/rpm/DISTRIBUTION/SRPMS
gpgcheck=1
gpgkey=https://deb.torproject.org/torproject.org/rpm/RPM-GPG-KEY-torproject.org.asc
配置完毕，安装tor总是不成功，报错如下：https://deb.torproject.org/torproject.org/rpm/DISTRIBUTION/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"
解决办法如下：
a. 打开/etc/yum.repos.d/xxxxx.repo，对于本例来说就是/etc/yum.repost.d/xxx.repo
b. 将项[xxx]中的enabled=1改为enabled=0
[root@web1 ~]# cd /etc/yum.repos.d
[root@web1 yum.repos.d]# vim tor.repo
将[tor.repo]中的enabled=1改为enabled=0
