Prepare TAS Management server

Prepare the TAS server designated as the Management server. The Management server holds the repositories with the Docker images to be deployed on the TAS Application and Datastore servers. The Management server has additional requirements compared to the TAS Application and Datastore servers.

The procedures for server preparation are based on third party software which is subject to change. The instructions as such are to be considered as a suggested method for server preparation. Alternative commands may be used. In addition, it is possible that some of the commands may not be necessary as your servers may already have the required software.

Before you begin

Verify that the Management server is prepared according to TAS server preparation and validation
Create TAS user group and TAS user accounts (TAS 8)
Use FQDNs for server configuration
Verify that the distribution images folder has at least 100 GB space available

Procedure

Create the data directory to store the index, configuration, log, and transaction log files, and assign the required permissions:
1. Create the /<data_folder> directory:
  Copy
```
mkdir -p /<data_folder>
```
  where:
  
  <data_folder> is the folder defined for data storage, and is by default opt/app/data.
  
  If you require a different data directory, you must define it in the Site Preparation Checklist.
2. Assign the TAS user group and the tas_app user as the owner of the directory:
  Copy
```
chown -R tas_app:tas /<data_folder>
```
3. Assign the following permissions:
  Copy
```
chmod -R 770 /<data_folder>
```
Create the /tas_installation directory and assign permissions:
1. Create the /tas_installation directory within the data folder:
  Copy
```
mkdir /<data_folder>/tas_installation
```
2. Assign the TAS user group and the tas_inst user as the owner of the directory:
  Copy
```
chown -R tas_inst:tas /<data_folder>/tas_installation
```
3. Assign the following permission:
  Copy
```
chmod -R 770 /<data_folder>/tas_installation/
```
Schedule a cron job in CronTab to purge log files:
1. Edit the current CronTab:
  Copy
```
crontab -e
```
2. Add the line to purge the log files every 30 minutes:
  Copy
```
30 * * * * find /<data_folder>/log -type f -mtime +15 -delete
```
Optional. Install diagnostic tools for troubleshooting:
Copy
```
yum -y install sysstat htop iotop iftop sysbench collectl
```
