Start mysql and memcached in Linux

 

Start mysql

 

# Cd/usr/local/mysql/support-files/

#./Mysql. server start

 

Start memcached

 

Cd/usr/local/memcached/bin/

./Memcached-d-m 256-u root-l 10.0.20.6-p000011-c 5000-P/usr/local/memcached/memcached1.pid

 

 

Startup options:

 

-D option is to start a daemon,

 

-M indicates the amount of memory allocated to memcache. The unit is MB. Here is 100 MB,

 

-U is the user who runs memcache. You can also use adduser to create a user for memcahed.

 

-L is the IP address of the listening server. The IP address 192.168.11.193 is specified here.

 

-P is the port for memcache listening. I have set 11211 here. Because it is the default port, the-p parameter is not specified.

 

-The "c" option is the maximum number of concurrent connections. The default value is 1024. I have set 256 here, which is based on the load of your server,

 

-P is the pid file for saving Memcache. Here I am saving it in/tmp/memcached. pid
