ubuntu 15.10 安装 Memcache

ubuntu 15.10 安装 Memcache

1, Memcached需要libevent支持，安装libevent。

    Debian/Ubuntu:

sudo apt-get install libevent-dev

    Redhat/Centos:

sudo yum install libevent-devel 

  

2, 下载 Memcached 编译安装。

   官方网址：http://memcached.org/downloads

wget http://memcached.org/latest (将 latest改为最新稳定版，实例如下)
wget http://memcached.org/files/memcached-1.4.31.tar.gz
tar -zxvf memcached-1.x.x.tar.gz
cd memcached-1.x.x
./configure && make && make test && sudo make install

 3，命令行下启动

memcached -d -m 128  -u root -l 127.0.0.1  -p 11211 -c 1024 -P

 
说明一下memcached服务的启动参数：

-p 监听的端口
-l 连接的IP地址, 默认是本机
-d start 启动memcached服务
-d restart 重起memcached服务
-d stop|shutdown 关闭正在运行的memcached服务
-d install 安装memcached服务
-d uninstall 卸载memcached服务
-u 以的身份运行 (仅在以root运行的时候有效)
-m 最大内存使用，单位MB。默认64MB
-M 内存耗尽时返回错误，而不是删除项
-c 最大同时连接数，默认是1024
-f 块大小增长因子，默认是1.25-n 最小分配空间，key+value+flags默认是48
-h 显示帮助

 

启动/结束
memcached -d -m 10 -u root -l 192.168.0.122 -p 11200 -c 256 -P /tmp/memcached.pid
-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，这里是10MB
-u 是运行Memcache的用户，这里是root
-l 是监听的服务器IP地址，如果有多个地址的话，这里指定了服务器的IP地址192.168.0.122
-p 是设置Memcache监听的端口，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，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
kill `cat /tmp/memcached.pid`

 

获取运行状态
echo stats | nc 127.0.0.1 11211
watch "echo stats | nc 127.0.0.1 11211" (实时状态)

 

4，命令行下连接/断开

连接:
$ telnet 127.0.0.1 11211
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

按 “ctrl + ]”进入 telnet>

断开:
telnet> quit
Connection closed.

 

5，  php测试

$mem = new Memcache;
$mem->connect("127.0.0.1", 11211);
$mem->set('key', 'This is a memcached test!', 0, 60);
$val = $mem->get('key');
echo $val;
