今天在安装memcached时出现了以下错误（tar: libevent-1.4.14b-stable.tar.gz: Cannot open: No such file or directory），（memcached）的安装请移步我的另一篇文章：http://www.jakehu.me/816

错误如下：

1. tar: libevent-1.4.14b-stable.tar.gz: Cannot open: No such file or directory
2. tar: Error is not recoverable: exiting now
3. memcached_ins.sh: line 35: cd: libevent-1.4.14b-stable: No such file or directory
4. memcached_ins.sh: line 36: ./configure: No such file or directory
5. make: *** No targets specified and no makefile found. Stop.

经过查看.sh脚本，发现如下代码

1. cd /tmp
2. wget -c https://github.com/downloads/libevent/libevent/libevent-1.4.14b-stable.tar.gz
3. wget -c http://memcached.googlecode.com/files/memcached-1.4.15.tar.gz
4. wget -c http://pecl.php.net/get/memcache-2.2.7.tgz
5. tar xf libevent-1.4.14b-stable.tar.gz
6. cd libevent-1.4.14b-stable
7. ./configure --prefix=/usr
8. make
9. [ $? != 0 ] && exit
10. make install
11. cd ..

瞬间就明白了，因为在国内网络无法访问Google所以无法下载libevent-1.4.14b-stable.tar.gz和memcached-1.4.15.tar.gz

解决办法：

手动把

https://github.com/downloads/libevent/libevent/libevent-1.4.14b-stable.tar.gz

http://memcached.googlecode.com/files/memcached-1.4.15.tar.gz

下载到本机，然后再上传到服务器/tmp目录里。

最后再运行：

1. wget -c http://down.wdlinux.cn/in/memcached_ins.sh
2. chmod 755 memcached_ins.sh
3. ./memcached_ins.sh

之后出现以下页面，就表示安装成功了
