JMeter Master Slave configuration is not working in CentOS -

i set master-slave load testing environment using jmeter. using 3 centos machines following ip's

xxx.xxx.xxx.1 (master) xxx.xxx.xxx.2 (slave1) xxx.xxx.xxx.3 (slave2) 

here steps did.

1) added following slaves jmeter.properties file:

remote_hosts=xxx.xxx.xxx.1 

2) added following master jmeter-server file

#rmi_host_def=-djava.rmi.server.hostname=xxx.xxx.xxx.2 `

then when i'm executing following command /apache-jmeter-2.13/bin folder of xxx.xxx.xxx.2 slave machine.(i don't have root user access have sudo root access)

sudo ./jmeter-server 

i'm getting error

./jmeter-server: line 32: ./jmeter: permission denied 

is master-slave setup correct? doing wrong here? need else setup master-slave?

add following client (master) jmeter.properties file:

remote_hosts= xxx.xxx.xxx.2,xxx.xxx.xxx.3 

add following servers (in each slave machines) jmeter-server:

rmi_host_def=-djava.rmi.server.hostname=xxx.xxx.xxx.2 (slave1)

&

rmi_host_def=-djava.rmi.server.hostname=xxx.xxx.xxx.3 (slave2)

then start jmeter-server.sh 2 slave

machines(xxx.xxx.xxx.2,xxx.xxx.xxx.3) using command

./jmeter-server 

then ran following command client machine(xxx.xxx.xxx.1) start remote start slaves.

./jmeter -n -t <testscript.jmx> -r
