如何从PHP重启memcached

Question

I have vps-hosting with centos. On this server are Apache, PHP, MySql. I installed memcached. And sometimes (once in 3-4 days) memcached stopping - I don't know why, in log file missing necessary information.

I found that solution - every 10 minutes run cron, which verify started or not memcached (through command memcached-tool), when memcached already crashed - i send e-mail and through server command line start memv=cached

But i would start memcached automatic, but i can't do this.

I tried so command

system("/etc/init.d/memcached start");
exec("service memcached start");
system("service memcached start");

but i haven't result.

You should use sudo to make php escalate to root before killing and starting memcached or you'll get permission deined.

P.S. try to check why memcached crashes instead of restarting it!!
