Installing SGE on the Execution Host

On the execution host, run the following command to install the NIS client installation package ypbind:
yum install ypbind -y

In this example, the CentOS 7.6 image is used as the local Yum source. You can change the Yum source in the /etc/yum.repos.d directory as required.
Modify the /etc/sysconfig/network file on the execution host.
1. Open the file.
```
vi /etc/sysconfig/network
```
2. Press i to enter the insert mode and enter the following information:
```
HOSTNAME=Name of the execution host
NETWORKING=yes
NISDOMAIN=huawei
```
  HOSTNAME specifies the name of the execution host, and NISDOMAIN specifies the domain name of the cluster. Set them based on actual situation.
3. Press Esc, enter :wq!, and press Enter to save the file and exit.
Modify the /etc/yp.conf file on the execution host.
1. Open the file.
```
vi /etc/yp.conf
```
2. Press i to enter the insert mode and add the following information to the end of the file:
```
domain huawei server 192.168.40.50
```
  In this example, 192.168.40.50 indicates the IP address of the master host. Replace it with the actual IP address.
3. Press Esc, type :wq!, and press Enter to save the file and exit.
Modify the /etc/nsswitch.conf file.
1. Open the file.
```
vi /etc/nsswitch.conf
```
2. Press i to enter the insert mode and enter the following information:
```
passwd:    files nis 
shadow:    files nis 
group:     files nis 
hosts:     files nis dns
```
3. Press Esc, type :wq!, and press Enter to save the file and exit.

Start the ypbind service.

systemctl start ypbind
systemctl enable ypbind

Install hwloc.
```
yum install hwloc* -y
```
In this example, the CentOS 7.6 image is used as the local Yum source. You can change the Yum source in the /etc/yum.repos.d directory as required.
Set the environment variable SGE_ROOT.
```
export SGE_ROOT=/path/to/SGE_ROOT
```

Load the SGE environment variables.

source /path/to/SGE_ROOT/default/common/settings.sh

Add the SGE environment variables to the .bashrc file for the environment variables to take effect permanently.
```
echo "source /path/to/SGE_ROOT/default/common/settings.sh" >> /root/.bashrc
```
Start the execd process on the execution host.
```
/path/to/SGE_ROOT/default/common/sgeexecd
```

Enable the execd process to automatically start as the system boots.

echo "/path/to/SGE_ROOT/default/common/sgeexecd" >> /etc/rc.d/rc.local
chmod +x /etc/rc.d/rc.local
