通过 LDAP 用户使用 IBM Spectrum LSF 的最佳实践

将 OpenLDAP 与 Spectrum LSF 集群集成后，请参阅以下指南以了解在以 LDAP 用户身份运行 LSF 命令和提交 LSF 作业时的最佳实践。

还可以从登录节点运行以下所有命令。

使用 ssh_to_management_node 值登录到管理节点，如 Schematics 作业日志的输出部分所示:
- 主管理节点:
```
ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -J vpcuser@<floating_IP_address> lsfadmin@<management_node_IP_address>
```
其中 <floating_IP_address> 是堡垒节点的浮动 IP 地址，<management_node_IP_address> 是管理节点的 IP 地址。
- 登录节点:
```
ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -J vpcuser@<floating_IP_address> lsfadmin@<login_node_IP_address>
```
其中 <floating_IP_address> 是堡垒节点的浮动 IP 地址，<login_node_IP_address> 是登录节点的 IP 地址。

切换到 LDAP 用户 (例如，切换到 lsfuser05):

$ [lsfadmin@lsfuser05-ubuntu-two-mgmt-1 ~]$ su lsfuser05
Password:
$ [lsfuser05@lsfuser05-ubuntu-two-mgmt-1 lsfadmin]#

以 LDAP 用户身份运行 LSF 命令:

$ [lsfuser05@lsfuser05-ubuntu-two-mgmt-1 lsfadmin]$ lshosts -w

lsfuser05-ubuntu-two-mgmt-3 X86_64 Intel_E5 12.5 2     7.5G   -      Yes    (mg)

$ [lsfuser05@lsfuser05-ubuntu-two-mgmt-1 lsfadmin]$ bhosts -w
