**Note: The LIGO standard UID for controls is 1001 across all systems. Any hosts connected to the FEC should follow this standard**
Add 'controls' and 'cdsadmin' user to sudo group. Create /etc/sudoers.d/users with the following:
```plaintext
cdsadmin ALL=(ALL) NOPASSWD: ALL
controls ALL=(ALL) NOPASSWD: ALL
```
**_From this point on, we will be using the ‘controls’ user with sudo privileges to enter the commands. Commands will be entered into the command line and will be denoted with the prefix ‘controls@x2fec’_**

# Create site, ifo directories
Modify the commands below to fit your ifo and site, as controls:
```
export SITE=TST
export site=tst
export IFO=X1
export ifo=x1
```
```plaintext
mkdir -p /opt/rtcds/$site/$ifo/chans/daq/archive
mkdir -p /opt/rtcds/$site/$ifo/log
mkdir -p /opt/rtcds/$site/$ifo/scripts
mkdir -p /opt/rtcds/$site/$ifo/chans/tmp
mkdir -p /opt/rtcds/$site/$ifo/chans/ipc
mkdir -p /opt/rtcds/$site/$ifo/rtbuild
mkdir -p /opt/rtcds/$site/$ifo/medm
mkdir -p /opt/rtcds/$site/$ifo/target/gds/bin
mkdir -p /opt/rtcds/$site/$ifo/target/gds/param
```
# Install Required Software
It is recommended to copy and paste the command below
The FEC exports the /opt/rtcds directory to the directly connected workstation, insert workstation ip into `<workstation-ip>`. Directions for mounting the NFS mount on the workstation will be included in the workstation setup instructions.**If you are configuring your front-end as a cymac (front-end and workstation on the same host), you can skip this step.**
Add the following content to `/etc/exports` and run `/usr/sbin/exportfs -a`. Restart the nfs-server.service.
**Option B** - Install master from Git repository If you are going to do development, especially on Debian 8 and newer, use a git checkout Create the 'rtscore' directory for it and go to it
At the top of ```/etc/advligorts/env``` and ```/etc/advligorts/systemd_env```, make sure lowercase vars ```ifo``` and ```site``` are set as in this example:
```
SITE=TST
IFO=X1
site=tst
ifo=x1
```
## Set RCG_LIB_PATH
You will also need to set the RCG_LIB_PATH environment variable for the controls user. This can be set in ```/etc/advligorts/env```
with the following addition.
```plaintext
# LIGO site environment files with hand-curated model paths
if [ $BASH_VERSION ] ; then
if [ -e /opt/rtcds/userapps/release/etc/userapps-user-env.sh ] ; then
## Install ezca, add soft-links (skip for CyMAC or standalone)
To build the real-time models, you also need the EPICS ezca package. However, this currently installs a level down at '/usr/lib/epics/extensions', so we need to add soft-links at /usr/lib/epics directories
We want to make sure caRepeater starts on boot. The file 'caRepeater.service' comes with EPICS base 3.15.5 and later. It needs to be customized to location of caRepeater. Create the file `/etc/systemd/system/caRepeater.service` with the following contents
```plaintext
#
# Linux systemd service file for the EPICS CA Repeater
**Note: The LIGO standard UID for controls is 1001 across all systems. Any hosts connected to the FEC should follow this standard**
