第一步，先安装lib-event

下载lib-event  的包http://libevent.org/

下载完之后，解压安装

1. ./configure –prefix=/usr （或 ./configure --program-prefix=/usr）
2. make
3. make install

第二步，安装memcached

下载memcached的包http://www.memcached.org/downloads

下载完之后。解压安装

1、./configure

2、make

3、make install

通过命令 ls -al /usr/local/bin/mem*检測是否成功安装

默认情况下memcached安装到/usr/local/bin下。

启动memcached server。在安装文件夹下启动

/usr/local/bin/memcached -d -m 10 -u root -l 127.0.0.1 -p 11211 -c 256 -P /tmp/memcached.pid

root@chiwei-VirtualBox:/home/chiwei/disk/service# ls
root@chiwei-VirtualBox:/home/chiwei/disk/service# ls -al /usr/local/bin/memcached 
-rwxr-xr-x 1 root root 495978  7月 23 16:16 /usr/local/bin/memcached
root@chiwei-VirtualBox:/home/chiwei/disk/service# cd /usr/local/bin/me
-su: cd: /usr/local/bin/me: 没有那个文件或文件夹
root@chiwei-VirtualBox:/home/chiwei/disk/service# cd /usr/local/bin/
root@chiwei-VirtualBox:/usr/local/bin# ls
memcached
root@chiwei-VirtualBox:/usr/local/bin# ./memcached -d -c 1024 -l 127.0.0.1 -p 10101 -m 1024 -u root
root@chiwei-VirtualBox:/usr/local/bin# telnet 127.0.0.1 10101

Trying 127.0.0.1...
Connected to 127.0.0.1.

stats

启动完之后，測试

telenet  127.0.0.1 10101

连接成功后，能够使用了

关闭memcached服务时，先查看tmp目录

root@chiwei-VirtualBox:~# ls
root@chiwei-VirtualBox:~# cd /tmp/
root@chiwei-VirtualBox:/tmp# ls
aptdaemon-WMCJDF                  qtsingleapp-chines-1a7c-3e8-lockfile

fcitx-socket-:0                   sni-qt_chinese-calendar_2043-z3cOqS

memcached.pid                     unity_support_test.1
qtsingleapp-chines-1a7c-3e8

有一个保存memcache的pid文件

kill `cat /tmp/memcached.pid`   键盘左上角的点符号

或者

root@chiwei-VirtualBox:~# ps -ef | grep memcached
root     24915  1584  0 16:36 ?

00:00:00 ./memcached -d -c 1024 -l 127.0.0.1 -p 10101 -m 1024 -u root
root     25011 10370  0 16:41 pts/15   00:00:00 grep --color=auto memcached
root@chiwei-VirtualBox:~# kill 24915
root@chiwei-VirtualBox:~# telnet 127.0.0.1 10101
