Wget http://www.monkey.org /~ Provos/libevent-1.2.tar.gz

Unpack

CD/usr/local
Tar-xzvf libevent-1.4.tar.gz
Tar-xzvf memcached-1.2.5.tar.gz

Handle libevent
CD/usr/local/libevent-1.2/

Make
Make install

Ll/usr/local/libevent/lib/
A file similar to the following exists:

Add memcached lib
Use ld_debug = libs bin/memcached-V to determine lib

-P <num> TCP port number to listen on (default: 11211)

-U <num> UDP port number to listen on (default: 0, 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 is indrr_any

-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 is 64 MB

-M Return Error on Memory Exhausted (rather than removing items)

-C <num> MAX simultaneous connections, default is 1024

-K lock down all paged memory. Note that there is

Limit on how much memory you may lock. Trying

Allocate more than that wowould 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)

-H print this help and exit

-I print memcached and libevent license

-B run a managed instanced (Mnemonic: buckets)

-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

If the preceding information is displayed, the installation is normal.
Note: Check the Lib folder to be added. When the following occurs:
Memcached: Error while loading shared libraries: libevent-1.3c.so.1: cannot open shared object file: no such file or directory

Use ld_debug = libs bin/memcached-V for debugging

 

Start memcache:
./Memcached-help
./Memcached-D-M 1024-u root-P 11211-C 1024-P/tmp/memcached. PID

Start

Echo/usr/local/memcached/bin/memcached-D-M 10-u root-l 218.16.118.105-P 11211-C 256-P/tmp/memcached. PID>/etc/rc. local

Startup parameters:
-D option is to start a daemon,

-M indicates the amount of memory allocated to memcache. The unit is mb. The default value is 64 MB.
-M Return Error on Memory Exhausted (rather than removing items)
-U is the user who runs memcache. If it is currently root, you need to use this parameter to specify the user.
-L is the IP address of the listening server. The default value is all NICs.

-P is the port used to set TCP listening for memcache, preferably over 1024.

-The C option is the maximum number of concurrent connections. The default value is 1024.
