在aws ec2实例上可用的yum repo只有libmemcached的旧版本：v 1.0.8。
任何人都可以告诉我如何获得更新的版本，如1.0.18，安装在aws ec2实例？
如果不支持， 可以添加哪个外部yum回购以安装更新的版本？

谢谢！
你可以试试Remi的RPM回购。 http://blog.remirepo.net/pages/Config-en
请注意，它取决于EPEL，并且在安装软件包时需要显式启用它：
yum --enablerepo=remi install XXX
注意：不确定它是否与Amazon Linux兼容。 如果不是的话，可以考虑使用CentOS 7，默认1.0.16。
我仍然试图使用一个外部回购解决scheme@Jukkabuild议，但直到我这样做，我能够用以下编译它：
sudo -i yum remove libmemcached.x86_64 yum install bzr.x86_64 yum install gcc-c++ mkdir -p /tmp/memcached cd /tmp/memcached wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz tar -zxvf libmemcached-1.0.18.tar.gz cd /tmp/memcached/ bzr branch lp:libmemcached cd libmemcached ./bootstrap.sh autoreconf NOTE YOU GET THE FOLLOWING ERROR BUT CONTINUE ANYWAY: "./bootstrap.sh:315: An attempt was made to set an invalid VENDOR=" cd ../libmemcached-1.0.18 ./configure make make test make install
