Installing a hub

4.2.3. Zenoss user SSH keys

Perform these procedures to install a new hub using the SSH authentication keys of the zenoss user on the master

host. (Someone must have root privileges on the hub host to perform the first procedure.)

4.2.3.1. Preparation tasks

1. Log in to the hub host as root, or as a user with superuser privileges.

2. Remove conflicting messaging systems.

a. Determine whether Matahari or Qpid are installed.

rpm -qa | egrep -i "matahari|qpid"

b. If the preceding command returns a result, remove the packages.

yum -y erase $(rpm -qa | egrep -i "matahari|qpid")

3. Enable network traffic through required ports.

• To enable traffic through specific ports, refer to Appendix B, "Required ports".

• To enable traffic through all ports, enter the following commands.

IPv4: service iptables stop; chkconfig iptables off

IPv6: service ip6tables stop; chkconfig ip6tables off

Note

You may open all ports at this time, and then close unneeded ports later.

4. Resource Manager is not compatible with Security-Enhanced Linux (SELinux) in enforcing mode. Follow these

steps to disable enforcing mode.

a. Change to enforcing in permissive mode (avoiding the need to reboot).

/bin/echo 0 > /selinux/enforce

b. Disable enforcing mode permanently by editing the /etc/selinux/config file.

/bin/sed -i.bak -e 's/^SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config

5. Install Oracle Java 1.6. (Java 1.7 is not supported.)

a. Only Oracle Java may be installed. Determine whether other Java pacakges are installed.

rpm -qa | egrep -i '(jdk|jre|java)'

If necessary, remove the other packages.

yum -y remove $(rpm -qa | egrep -i '(jdk|jre|java)')

b. Download the self-installing binary of Oracle Java SE Runtime Environment 6u45 from the Java SE 6 Downloads

page. The file to download is jre-6u45-linux-x64-rpm.bin.

c. Add execute permission to the self-installing binary.

chmod +x ./jre-6u45-linux-x64-rpm.bin

d. Install the Oracle JRE.
