Добавляем memcached в автозагрузку

Создаем конфиг
touch /etc/memcached.conf

В него вставляем следующиее:
#Memory a usar
-m 16
# default port
-p 11211
# user to run daemon nobody/apache/www-data
-u nobody
# only listen locally
-l 127.0.0.1

если нада — отредактируем под потребности

Создаем скрипт запуска
touch /etc/init.d/memcached
chmod +x /etc/init.d/memcached

В него вставляем
#!/bin/bash
#
# memcached    This shell script takes care of starting and stopping
#              standalone memcached.

Создаем демона для запуска memcached
touch /usr/local/bin/start-memcached
chmod +x  /usr/local/bin/start-memcached

В него вставляем:

Тестируем:
/etc/init.d/memcached restart
Shutting down memcached:                                   [  OK  ]
Starting memcached:                                                [  OK  ]

Проверяем с какими параметрами запущен memcached:
ps aux |grep memca
nobody    1721  0.0  0.5  72732  5184 ?        Sl   20:53   0:00 /usr/local/bin/memcached -u root -m 128 -p 11211 -u nobody -l 127.0.0.1

И добавляем его в автозагрузку:
chkconfig memcached on
chkconfig —list | grep memcached
memcached       0:off   1:off   2:on    3:on    4:on    5:on    6:off
