linux memcached开机启动

方法一：

在/etc/rc.d/rc.local 加入以下代码

/usr/local/memcached/bin/memcached  -u root -d -m 2048 -l 192.168.70.1 -p 11211 -P /tmp/memcached.pid

// 所有机器都能访问
/usr/local/memcached/bin/memcached  -u root -d -m 2048 -l 0.0.0.0 -p 11211 -P /tmp/memcached.pid

// 不指定ip，默认只有本机访问
/usr/local/memcached/bin/memcached  -u deamon -d -m 2048 -p 11211 -P /tmp/memcached.pid

用户最好是 apache或 deamon

权限 （权限不够，无法开启启动memcached）

# cd /etc/rc.d
# chmod 777 rc.local
// 或者
# chmod 777 /etc/rc.d/rc.local

方法二：

// 写服务代码
vim /etc/init.d/memcached

粘贴以下代码

注意2处：memcached的安装路径

#cd /etc/init.d
#chmod 775 memcached
//将memcached加入系统服务
#chkconfig --add memcached
#chkconfig memcached on
//以服务方式运行memcached

启动与关闭

#service memcached start

启动
/etc/rc.d/init.d/memcached  start  
/etc/rc.d/init.d/memcached  stop
/etc/rc.d/init.d/memcached  restart
