1.安装Memcached

1.下载Memcached及其依赖 下载memcached-1.4.24.tar.gz和libevent-2.0.22-stable.tar.gz文件并解压如下：

   
 

    
  
[lizhiwei@localhost libevent]$ tar -zxvf libevent-2.0.22-stable.tar.gz 
    
  

    
  
[lizhiwei@localhost Memcached]$ tar -zxvf memcached-1.4.24.tar.gz 
   
 

2.安装memcached 先安装
libevent：

   
 

    
  
[lizhiwei@localhost libevent-2.0.22-stable]$ cd /home/lizhiwei/SoftWare/libevent/libevent-2.0.22-stable
    
  
[lizhiwei@localhost libevent-2.0.22-stable]$ ./configure -prefix=/home/lizhiwei/InstallSoft/libevent 
    
  
[lizhiwei@localhost libevent-2.0.22-stable]$ make
    
  
[lizhiwei@localhost libevent-2.0.22-stable]$ make install
   
 

安装memcached，同时需要安装中指定libevent的安装位置：

   
 

    
  
[lizhiwei@localhost libevent-2.0.22-stable]$ cd /home/lizhiwei/SoftWare/Memcached/memcached-1.4.24
    
  
[lizhiwei@localhost memcached-1.4.24]$ ./configure -prefix=/home/lizhiwei/InstallSoft/memcached -with-libevent=/home/lizhiwei/InstallSoft/libevent/
    
  
[lizhiwei@localhost memcached-1.4.24]$ make
    
  
[lizhiwei@localhost memcached-1.4.24]$ make install
   
 

此时
memcached安装完成，安装路径：
/
home
/
lizhiwei
/
InstallSoft
/
memcached

2.启动Memcached

1.启动memcached并参看服务

   
 

    
  
[lizhiwei@localhost memcached]$ cd /home/lizhiwei/InstallSoft/memcached/bin/
    
  
[lizhiwei@localhost bin]$ ll
    
  
total 356
    
  
-rwxr-xr-x. 1 lizhiwei lizhiwei 360894 Oct 1 20:52 memcached
    
  
[lizhiwei@localhost bin]$ ./memcached -d -m 10 -u lizhiwei -l 127.0.0.1 -p 12000 -c 256 -P /tmp/memcached.pid 
    
  
[lizhiwei@localhost bin]$ ps -ef | grep memcached
    
  
lizhiwei 24004 1 0 20:59 ? 00:00:00 ./memcached -d -m 10 -u lizhiwei -l 127.0.0.1 -p 12000 -c 256 -P /tmp/memcached.pid
    
  
lizhiwei 24018 14869 0 21:00 pts/2 00:00:00 grep memcached
    
  
[lizhiwei@localhost bin]$ cat /tmp/memcached.pid
    
  
24004
    
  
[lizhiwei@localhost bin]$ 
   
 

./

pid 启动命令说明： -d 选项是启动一个守护进程 -m 是分配给Memcache使用的内存数量，单位是MB，我这里是10MB -u 是运行Memcache的用户，我这里是lizhiwei -l 是监听的服务器IP地址，如果有多个地址的话，我这里指定了服务器的IP地址127.0.0.1 -p 是设置Memcache监听的端口，我这里设置了12000，最好是1024以上的端口 -c 选项是最大运行的并发连接数，默认是1024，我这里设置了256，按照你服务器的负载量来设定 -P 是设置保存Memcache的pid文件，我这里是保存在 /tmp/memcached.pid
2.停止Memcache服务 使用
kill
–
9
进程PID 命令停止
Memcache服务

   
 

    
  
[lizhiwei@localhost bin]$ ps -ef | grep memcached
    
  
lizhiwei 24004 1 0 20:59 ? 00:00:00 ./memcached -d -m 10 -u lizhiwei -l 127.0.0.1 -p 12000 -c 256 -P /tmp/memcached.pid
    
  
lizhiwei 24069 14869 0 21:07 pts/2 00:00:00 grep memcached
    
  
[lizhiwei@localhost bin]$ kill -9 24004
    
  
[lizhiwei@localhost bin]$ ps -ef | grep memcached
    
  
lizhiwei 24072 14869 0 21:07 pts/2 00:00:00 grep memcached
    
  
[lizhiwei@localhost bin]$ 
   
 

3.连接Memcache服务

   
 

    
  
[lizhiwei@localhost ~]$ telnet 127.0.0.1 11211
    
  
Trying 127.0.0.1...
    
  
Connected to 127.0.0.1.
    
  
Escape character is '^]'.
    
  
set name 0 64 5
    
  
abcde
    
  
STORED
    
  
get name
    
  
VALUE name 0 5
    
  
abcde
    
  
END
    
  
quit
    
  
Connection closed by foreign host.
    
  
[lizhiwei@localhost ~]$ 
   
 

telnet 使用说明：
telnet
127.0
.
0.1

11211 连接到IP地址127.0.0.1，端口号11211
set

5 格式：<command name> <key> <flags> <exptime> <bytes>
    
<command name> ：set/add/replace
    
<key> ：查找关键字
    
<flags> ：整型参数，客户机使用它存储关于键值对的额外信息
    
<exptime> ：该数据的存活时间（以秒为单位，0 表示永远） 
    
<bytes> ：存储字节数，注意：设置了存储大小就必须存储一样大小的数据，否则会操作失败
