1）FATE
FATE (Federated AI Technology Enabler) is an open source project initiated by the AI department of WeBank. It provides a secure computing framework based on data privacy protection and provides strong secure computing support for machine learning, deep learning, and migration learning algorithms. The security bottom layer supports a variety of multi-party secure computer mechanisms such as homomorphic encryption, secret sharing, and hashing. The algorithm layer supports logistic regression, boosting, and federated migration learning in the multi-party secure computing mode.
2）EggRoll
Eggroll is a large-scale distributed architecture suitable for machine learning and deep learning, including computing, storage and communication modules. Provide bottom support for FATE framework.
3）FATE Official Website ：https://fate.fedai.org/
This article will introduce the deployment of FATE cluster using ansible deployment script.

1) Certificate Production
vi /data/projects/ansible-nfate-1.*/tools/make.sh
#1. The custom security certificate needs to be deployed at both ends at the same time, and only one end needs to be manually processed. The manual processing part will not be introduced temporarily.
#2. The security certificate supports the following deployment methods:
1) Deploy host+guest, host and guest use secure certificate communication.
2) Deploy host+exchange+guest, where host and exchange use secure certificates to communicate, and guest and exchange communicate normally.
3) Deploy host+exchange+guest, where guest and exchange use secure certificates to communicate, and host and exchange communicate normally.
guest_host="192.168.0.1" ---Modify according to the actual IP
host_host="192.168.0.2" ---Modify according to the actual IP
exchange_host="192.168.0.88" --- Modify according to the actual IP, this example does not need to be modified without deployment
2) Execute Script To Make Certificate
cd tools
sh ./make.sh
Certificate files will be generated in the keys/host and guest directories.
3) Copy The Certificate To The Deployment Directory
sh cp-keys.sh host guest
The certificate file will be copied to the roles/eggroll/files/keys directory
Special Note:
1. Currently, script deployment only supports 2 parties to set up certificate authentication. (host&guest, host&exchange, guest&exchange)
- ModifyThe Initialization Host IP
vi /data/projects/ansible-nfate-1.*/environments/prod/hosts

nohup sh ./boot.sh prod -D> logs/boot.log 2>&1 &
The deployment log is output in the logs directory, and check whether there is an error in real time:
#Relative ansible-nfate-* directory
cd logs
tail -f ansible.log (check the deployment in real time, if there is no such log file, you need to check whether ansible is installed)
List of check items fail prompt:
1. "Warning: now swap is 0, need to turn up"
---The virtual memory is not set, please refer to the previous chapter to set it, not less than 128G.
2. "Warning: key fate process exists, please has a check and clean"
---The environment has not been cleaned up, and the previously deployed fate process needs to be stopped.
3. "Warning: these ports: 4670 4671 9360 9370 9380 have been used"
---The environment has not been cleaned up, and the previously deployed fate process needs to be stopped.
4. "Warning: if reinstall mysql, please stop mysql, and rename /etc/my.cnf"
---mysql did not stop, it needs to be stopped. If there is a /etc/my.cnf file, mv needs to be renamed.
5. "Waring: please rename /data/projects/fate"
---The fate directory exists, you need to mv first.
6. "Warning: please rename /data/projects/data/fate/mysql"
---/data/projects/data exists, mv is required.
7. "Warning: supervisor_fate_conf exists, please remove ls /data/projects/common/supervisord/supervisord.d/fate-*.conf"
--- The /data/projects/common directory exists, and mv is required.
Restart after fateflow deployment:
#Because fate_flow depends on more components, there may be exceptions in startup. The processing is as follows:
netstat -tlnp | grep 9360
If there is no port, restart fateflow:
sh service.sh stop fate-fateflow

Some other parameters that may be useful include:
- -f: File type used. "fast" represents the breast data set, and "normal" represents the default credit data set.
- --add_sbt: If it is set to 1, the secureboost task will be started after lr is run. If it is set to 0, the secureboost task will not be started. If this parameter is not set, the system defaults to 1.
If the word "success" is displayed in the result after a few minutes, it indicates that the operation has run successfully. If "FAILED" appears or the program is stuck, it means the test has failed.
Just replace "fast" with "normal" in the command, and the rest is the same as in fast mode.
Fateboard is a web service. If the fateboard service is successfully started, you can view the task information by visiting http://192.168.0.1:8080 and http://192.168.0.2:8080. If there is a firewall between the local office computer and the server, you need to enable it.
Execute under the target server (192.168.0.1 192.168.0.2) app user
cd /data/projects/common/supervisord
Start/Stop/Restart/View all:
#Note: Because mysql is a basic component, the startup is slow. It is recommended to restart all components first, then start mysql first, and then start other components
sh service.sh start/stop/restart/status all
#Note: Because fateflow depends on many components, restarting all operations may cause fateflow to start abnormally. The processing is as follows:
netstat -tlnp | grep 9360
If there is no port, restart fateflow:
sh service.sh stop fate-fateflow
sh service.sh start fate-fateflow
Start/stop/restart/view a single module (optional: clustermanager, nodemanager, rollsite, fateflow, fateboard, mysql):
sh service.sh start/stop/restart/status fate-clustermanager

Support the uninstallation of all services and the uninstallation of a single service.
cd /data/projects/ansible-nfate-1.*
sh ./uninstall.sh prod all
#Uninstall command description
sh ./uninstall.sh $arg1 $arg2
- The $arg1 parameter is the same as the parameter executed by init in step 4.4.1, and is test|prod.
- The $arg2 parameter is the selected service, the optional parameter is (all|mysql|eggroll|fate_flow|fateboard), all means uninstall all services.
Configuration file path: /data/projects/fate/eggroll/conf/eggroll.properties
Configuration parameter: eggroll.session.processors.per.node
Assuming that the number of CPU cores (cpu cores) is c, the number of Nodemanagers is n, and the number of tasks that need to run simultaneously is p, then:
egg_num=eggroll.session.processors.per.node = c * 0.8 / p
partitions (roll pair partition number) = egg_num * n
