Linux setup memcached boot up

memcached Boot Mode

Method One:

Append the start command to the /etc/rc.d/rc.local file

/usr/local/memcached/bin/memcached-u root-d-M 2048-l 192.168.137.99-p 11211-p/tmp/memcached.pid

You can also specify no IP, which is native by default, such as

/usr/local/memcached/bin/memcached-u deamon-d-M 2048-p 11211-p/tmp/memcached.pid

The user is preferably Apache or deamon

Method Two:

#写服务脚本

Vim/etc/init.d/memcached

Paste the following code

#!/bin/sh # # memcached:memcached Daemon # # Chkconfig:-# description:memcached Daemon # # #   Ource function Library. . /etc/rc.d/init.d/functions. /etc/sysconfig/network #[${networking} = "No"] && exit 0 #[-r/etc/sysconfig/dund] | | Exit 0 #. /etc/sysconfig/dund #[-Z "$DUNDARGS"] && exit 0 memcached= "/usr/local/memcached/bin/memcached" server_ip= "19 2.168.137.98 "server_port=" 11211 "[-F $MEMCACHED] | | Exit 1 start () {echo-n $ "starting memcached:" Daemon $MEMCACHED-u daemon-d-M 2048-l $SERVER _i          P-page $SERVER _port-p/tmp/memcached.pid echo} stop () {echo-n $ "shutting down memcached:"   Killproc memcached Echo} # See how we were called.

The-c option is the maximum number of concurrent connections that are running, by default 1024
-P is a PID file that is set to save Memcache

You can also start multiple daemons, but the ports cannot be duplicated

-P Specify port number (default 11211)
