Ubuntu:将 Memcached 作为守护进程运行

Question

我已经在 Ubuntu 上安装了 memcached。我怎样才能将它作为守护进程运行，以便它在后台运行并且我可以在我的 Rails 应用程序中使用它？

memcached 默认配置为在启动时运行，至少在 10.10 上是这样:

# apt-get install memcached
...
Setting up memcached (1.4.5-1ubuntu1) ...
Starting memcached: memcached.
# ls -l /etc/rc*.d/*memcached
lrwxrwxrwx 1 root root 19 2011-03-23 13:36 /etc/rc0.d/K20memcached -> ../init.d/memcached
lrwxrwxrwx 1 root root 19 2011-03-23 13:36 /etc/rc1.d/K20memcached -> ../init.d/memcached
lrwxrwxrwx 1 root root 19 2011-03-23 13:36 /etc/rc2.d/S20memcached -> ../init.d/memcached
lrwxrwxrwx 1 root root 19 2011-03-23 13:36 /etc/rc3.d/S20memcached -> ../init.d/memcached
lrwxrwxrwx 1 root root 19 2011-03-23 13:36 /etc/rc4.d/S20memcached -> ../init.d/memcached
lrwxrwxrwx 1 root root 19 2011-03-23 13:36 /etc/rc5.d/S20memcached -> ../init.d/memcached
lrwxrwxrwx 1 root root 19 2011-03-23 13:36 /etc/rc6.d/K20memcached -> ../init.d/memcached
#  

在运行级别 2、3、4 和 5 中，memcached 将运行。

如果您不确定，可以使用status 运行初始化脚本:

# /etc/init.d/memcached status
 * memcached is running
