magent启动脚本

修改上一篇的memcached启动脚本的相关配置参数就得到magent的启动脚本了，跟memcached的启动脚本一样,只修改如下的相关参数即可：

MAGENT_CONF=" -u root -n 51200 -l 192.168.10.11 -p 12000 -s 192.168.10.12:11211 192.168.10.13:11211 -b 192.168.101.11:11211 "

magent相关参数参考：

memcached agent v0.4 Build-Date: Mar 28 2012 06:20:51
Usage:
  -h this message
  -u uid
  -g gid
  -p port, default is 11211. (0 to disable tcp support)
  -s ip:port, set memcached server ip and port
  -b ip:port, set backup memcached server ip and port
  -l ip, local bind ip address, default is 0.0.0.0
  -n number, set max connections, default is 4096
  -D don't go to background
  -k use ketama key allocation algorithm
  -f file, unix socket path to listen on. default is off
  -i number, set max keep alive connections for one memcached server, default is 20
  -v verbose

完整脚本如下：
