ubuntu server 下安装 memcached

安装memcached

sudo apt-get install memcache 

如果系统找不到 memcache 安装包

更新软件源
您可以使用以下列表中的任何一个源镜像只要往您的 /etc/apt/sources.list 文件中像下面这样添加一行:

deb http://security.ubuntu.com/ubuntu hardy-security main universe

进行重新安装一下

 sudo apt-get update
         sudo apt-get install memcache

检验是否安装成功.
－－－－－
1. 安装成功之后,memcache就自己启动了.通过进程查看一下

   ps -aux

会查到一条记录

   /usr/bin/memcached -m 64 -p 11211 -u nobody -l 127.0.0.1

显示的就是 memcached 的端口11211 用户nobody 地址 127.0.0.1
2. 连接memcached 服务器

   telnet 127.0.0.1 11211

然后输入

   stats

就显示出来当前memcached的各种参数了..

sysadmin@ubuntu:/etc/apt$ telnet 127.0.0.1 11211 
Trying 127.0.0.1...
Connected to 127.0.0.1.

3. 手动启动memcached

   memcached  -d  -m 128 -l 127.0.0.1 -p 11211 -u root

以root用户，分配最大2GM内存启动memcache

   memcached  -d  -m 128 -l 127.0.0.1 -p 11212 -u root

在另外一个端口11212启动另外一个memcache实例
