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. Escape character is '^]'. stats STAT pid 3065 STAT uptime 170 STAT time 1334121278 STAT version 1.4.7 STAT libevent 2.0.12-stable STAT pointer_size 64 STAT rusage_user 0.004000 STAT rusage_system 0.000000 STAT curr_connections 5 STAT total_connections 7 STAT connection_structures 6 STAT cmd_get 0 STAT cmd_set 0 STAT cmd_flush 0 STAT get_hits 0 STAT get_misses 0 STAT delete_misses 0 STAT delete_hits 0 STAT incr_misses 0 STAT incr_hits 0 STAT decr_misses 0 STAT decr_hits 0 STAT cas_misses 0 STAT cas_hits 0 STAT cas_badval 0 STAT auth_cmds 0 STAT auth_errors 0 STAT bytes_read 140 STAT bytes_written 856 STAT limit_maxbytes 67108864 STAT accepting_conns 1 STAT listen_disabled_num 0 STAT threads 4 STAT conn_yields 0 STAT bytes 0 STAT curr_items 0 STAT total_items 0 STAT evictions 0 STAT reclaimed 0 END
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
