Matthew Kassawara 5ee72cfa36 [install] Fix various minor problems

Fix the following minor problems to reduce work after
stable/liberty branching:

1) RDO: Revert Python MySQL library from PyMySQL to MySQL-python
   due to lack of support for the former.
2) RDO: Explicitly install 'ebtables' and 'ipset' packages due
   to dependency problems.
3) General: Change numbered list to bulleted list for lists with
   only one item.
4) General: Restructure horizon content to match other services.
   More duplication of content, but sometimes RST conditionals
   are terrible and distro packages should use the same
   configuration files.
5) General: Restructure NoSQL content to match SQL content.
6) General: Improve clarity of NTP content.

Perform these steps on the controller node.

Install and configure components

Install the packages:

ubuntu or debian

# apt-get install chrony

rdo

# yum install chrony

obs

On openSUSE:

# zypper addrepo -f obs://network:time/openSUSE_13.2 network_time
# zypper refresh
# zypper install chrony

On SLES:

# zypper addrepo -f obs://network:time/SLE_12 network_time
# zypper refresh
# zypper install chrony

Note

The packages are signed by GPG key 17280DDF. You should verify the fingerprint of the imported GPG key before using it.

ubuntu or debian

Edit the /etc/chrony/chrony.conf file and add, change, or remove the following keys as necessary for your environment:
```
server NTP_SERVER iburst
```
Replace NTP_SERVER with the hostname or IP address of a suitable more accurate (lower stratum) NTP server. The configuration supports multiple server keys.

Note

By default, the controller node synchronizes the time via a pool of public servers. However, you can optionally configure alternative servers such as those provided by your organization.
Restart the NTP service:
```
# service chrony restart
```

rdo or obs

Edit the /etc/chrony.conf file and add, change, or remove the following keys as necessary for your environment:
```
server NTP_SERVER iburst
```
Replace NTP_SERVER with the hostname or IP address of a suitable more accurate (lower stratum) NTP server. The configuration supports multiple server keys.

Note

By default, the controller node synchronizes the time via a pool of public servers. However, you can optionally configure alternative servers such as those provided by your organization.
To enable other nodes to connect to the chrony daemon on the controller, add the following key to the /etc/chrony.conf file:
```
allow 10.0.0.0/24
```
If necessary, replace 10.0.0.0/24 with a description of your subnet.
Start the NTP service and configure it to start when the system boots:
```
# systemctl enable chronyd.service
# systemctl start chronyd.service
```
