liunx下安装memcached
先把两个包下载下来:
memcached-1.4.5.tar.gz
libevent-2.0.9-rc.tar.gz
放在一个目录下,安装libevent
tar xzfv libevent-2.0.9-rc.tar.gz
cd libevent-2.0.9-rc/
./configure --prefix=/usr?
make
make install
查看是否安装成功? 成功会出现如下页面:

解压另一个memcached 包:
tar xzfv memcached-1.4.5.tar.gz
cd memcached-1.4.5
./configure --prefix=/usr/local --with-libevent=/usr//?? (安装到? usr/local 目录下,? --with-libevent 是指之前的libevent的目录)
make
make install
查看是否成功:
到? memcached的目录:
?memcached -h
-p <num>????? TCP port number to listen on (default: 11211)
-U <num>????? UDP port number to listen on (default: 11211, 0 is off)
-s <file>???? UNIX socket path to listen on (disables network support)
-a <mask>???? access mask for UNIX socket, in octal (default: 0700)
-l <ip_addr>? interface to listen on (default: INADDR_ANY, all addresses)
-d??????????? run as a daemon
-r??????????? maximize core file limit
-u <username> assume identity of <username> (only when run as root)
-m <num>????? max memory to use for items in megabytes (default: 64 MB)
-M??????????? return error on memory exhausted (rather than removing items)
-c <num>????? max simultaneous connections (default: 1024)
-k??????????? lock down all paged memory.? Note that there is a
????????????? limit on how much memory you may lock.? Trying to
????????????? allocate more than that would fail, so be sure you
????????????? set the limit correctly for the user you started
????????????? the daemon with (not for -u <username> user;
????????????? under sh this is done with 'ulimit -S -l NUM_KB').
-v??????????? verbose (print errors/warnings while in event loop)
-vv?????????? very verbose (also print client commands/reponses)
-vvv????????? extremely verbose (also print internal state transitions)
-h??????????? print this help and exit
-i??????????? print memcached and libevent license
-P <file>???? save PID in <file>, only used with -d option
-f <factor>?? chunk size growth factor (default: 1.25)
-n <bytes>??? minimum space allocated for key+value+flags (default: 48)
-L??????????? Try to use large memory pages (if available). Increasing
????????????? the memory page size could reduce the number of TLB misses
????????????? and improve the performance. In order to get large pages
????????????? from the OS, memcached will allocate the total item-cache
????????????? in one large chunk.
-D <char>???? Use <char> as the delimiter between key prefixes and IDs.
????????????? This is used for per-prefix stats reporting. The default is
????????????? ":" (colon). If this option is specified, stats collection
????????????? is turned on automatically; if not, then it may be turned on
????????????? by sending the "stats detail on" command to the server.
-t <num>????? number of threads to use (default: 4)
-R??????????? Maximum number of requests per event, limits the number of
????????????? requests process for a given connection to prevent
????????????? starvation (default: 20)
-C??????????? Disable use of CAS
-b??????????? Set the backlog queue limit (default: 1024)
-B??????????? Binding protocol - one of ascii, binary, or auto (default)
-I??????????? Override the size of each slab page. Adjusts max item size
????????????? (default: 1mb, min: 1k, max: 128m)
出现这些为安装成功:
?
进入memcached的安装目录的bin目录下，启动memcached:
root@tike:/usr/local/bin# ./memcached -d? -m 512 -i 127.0.0.1 -p 11211 -P /tmp/memcached.pid
查看：
telnet 127.0.0.1 11211
stats命令查看访问情况
