aws ec2 實例上可用的 yum 儲存庫只有舊版本的libmemcached：v 1.0.8。

誰能告訴我如何在 aws ec2 實例上安裝更新的版本，如 1.0.18？

我可以添加哪個外部 yum 儲存庫來安裝更新的版本，即使它不受支持？

謝謝！

正如@Jukka 建議的那樣，我仍在嘗試使用外部儲存庫來獲得解決方案，但在我這樣做之前，我能夠使用以下內容對其進行編譯：

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

你可以試試 Remi 的 RPM repo。http://blog.remirepo.net/pages/Config-en

請注意，它取決於 EPEL，並且您需要在安裝軟體包時顯式啟用它：

yum --enablerepo=remi install XXX

注意：不確定它是否與 Amazon Linux 兼容。如果沒有，請考慮使用預設為 1.0.16 的 CentOS 7。
