Question 7

Consider the steps to enable the Pluggable Authentication Module (PAM) to use cgroup rules for a 64-bit system:

1. Install the libcgroup-pam software package.

2. Ensure that the PAM module has been installed and exists: /lib64/security/ pam_cgroup.so.

3. Edit the /ets/pam.d/su configuration file and add a line: session optional pam_cgroup.so.

4. Edit the /ets/pam.d/su configuration file and add a line: auth sufficient pam_cgroup.so.

5. Configure /etc/cgconfig.conf.

6. Configure /etc/cgrules.conf.

7. Log out all users that are affected by the cgroup settings in the /etc/cgrules.conf file.

8. Enable and start the cgred service.

9. Reboot the system.

Question 8

You dynamically configure a system to concurrently run tasks A1 and A2 using these commands:

# mkdir /cgroup/cpu

# mount –t cgroup –o cpu cpu /cgroup/cpu

# mkdir /cgroup/cpu/A1

# mkdir /cgroup/cpu/A2

# echo 5 > /cgroup/cpu/A1/cpu.shares

# echo 5 > /cgroup/cpu/A2/cpu.shares

# mkdir /cgroup/cpuacct

# mount –t cgroup –o cpuacct cpuacct /cgroup/cpuacct

You want to generate a /etc/cgconfig.conf configuration fail that contains the current cgroup configuration on the system.
