+# Automatic service start
+
+This document describes how to configure the automatic pull-up of the Doris cluster to ensure that services are not pulled up in time after service breaks down due to special circumstances in the production environment.
+
+The automatic pull-up service of FE and BE must be configured after the Doris cluster is completely set up.
+
+## Systemd Configures the Doris service
+
+For details about systemd usage and parameter parsing, see [here](https://blog.51cto.com/arm2012/1963238)
+
+### sudo permission control
+
+sudo permissions are required to control the doris service using systemd. To ensure the minimum granularity of sudo permission assignment, you can assign the systemd control permission of doris-fe and doris-be services to specified non-root users. Configure the systemctl management permission for doris-fe and doris-be in visudo.
+
+```
+Cmnd_Alias DORISCTL=/usr/bin/systemctl start doris-fe,/usr/bin/systemctl stop doris-fe,/usr/bin/systemctl start doris-be,/usr/bin/systemctl stop doris-be
+
+## Allow root to run any commands anywhere
+root ALL=(ALL) ALL
+doris ALL=(ALL) NOPASSWD:DORISCTL
+```
+
+### Configuration procedure
+
+1. Download the doris-fe.service file: [doris-fe.service](https://github.com/apache/doris/blob/master/tools/systemd/doris-fe.service)
+
+2. The details of doris-fe.service are as follows:

+
+#### Matters needing attention
+
+- ExecStart and ExecStop are configured based on actual be paths
+
+5. Service configuration
+
+ Place doris-fe.service and doris-be.service in the /usr/lib/systemd/system directory
+
+6. Set self-start
+
+ After you add or modify the configuration file, you need to reload it
+
+ ```
+ systemctl daemon-reload
+ ```
+
+ Set the start, the essence is in the/etc/systemd/system/multi - user. Target. Wants/add service file link
+
+ ```
+ systemctl enable doris-fe
+ systemctl enable doris-be
+ ```
+
+7. Service initiation
+
+ ```
+ systemctl start doris-fe
+ systemctl start doris-be
+ ```
+
+## Supervisor configures the Doris service
+
+Supervisor Specific use and parameter analysis can be referred to [here](http://supervisord.org/)
+
+Supervisor configuration automatically pulls up the supervisor configuration. You can install the supervisor directly using the yum command or manually using pip. The pip manual installation process is complicated, and only the yum deployment mode is displayed.Manual deployment refer to [here] (http://supervisord.org/installing.html) for installation deployment.
+
+### Configuration procedure
+
+1. yum Install supervisor
+
+ ```
+ yum install epel-release
+ yum install -y supervisor
+ ```
+
+2. Start the service and view the status
+
+ ```
+ systemctl enable supervisord # bootstrap
+ systemctl start supervisord # Start the supervisord service
+ systemctl status supervisord # Check the supervisord service status
+ ps -ef|grep supervisord # Check whether the supervisord process exists
+ ```
+
+3. Configure BE process management
+
+ ```
+ Modify the start_be.sh script remove the last symbol &
+
+ vim /path/doris/be/bin/start_be.sh
+ Take this code : nohup $LIMIT ${DORIS_HOME}/lib/palo_be "$@" >> $LOG_DIR/be.out 2>&1 </dev/null &
+ Be changed to : nohup $LIMIT ${DORIS_HOME}/lib/palo_be "$@" >> $LOG_DIR/be.out 2>&1 </dev/null
+ ```
+
+ Create a supervisor process management configuration file for the BE
+
+ ```
+ vim /etc/supervisord.d/doris-be.ini
+
+ [program:doris_be]
+ process_name=%(program_name)s
+ directory=/path/doris/be/be
+ command=sh /path/doris/be/bin/start_be.sh
+ autostart=true
+ autorestart=true
+ user=root
+ numprocs=1
+ startretries=3
+ stopasgroup=true
+ killasgroup=true
+ startsecs=5
+ #redirect_stderr = true
+ #stdout_logfile_maxbytes = 20MB
+ #stdout_logfile_backups = 10
+ #stdout_logfile=/var/log/supervisor-palo_be.log
+ ```
+
+4. Configure FE process management
+
+ ```
+ Modify the start_fe.sh script remove the last symbol &
+
+ vim /path/doris/fe/bin/start_fe.sh
+ Take this code : nohup $LIMIT $JAVA $final_java_opt org.apache.doris.PaloFe ${HELPER} "$@" >> $LOG_DIR/fe.out 2>&1 </dev/null &
+ Be changed to : nohup $LIMIT $JAVA $final_java_opt org.apache.doris.PaloFe ${HELPER} "$@" >> $LOG_DIR/fe.out 2>&1 </dev/null
+ ```
+
+ Create a supervisor process management configuration file for FE
+
+ ```
+ vim /etc/supervisord.d/doris-fe.ini
+
+ [program:PaloFe]
+ environment = JAVA_HOME="/usr/local/java"
+ process_name=PaloFe
+ directory=/path/doris/fe
+ command=sh /path/doris/fe/bin/start_fe.sh
+ autostart=true
+ autorestart=true
+ user=root
+ numprocs=1
+ startretries=3
+ stopasgroup=true
+ killasgroup=true
+ startsecs=10
+ #redirect_stderr=true
+ #stdout_logfile_maxbytes=20MB
+ #stdout_logfile_backups=10
+ #stdout_logfile=/var/log/supervisor-PaloFe.log
+ ```
+
+5. Configure Broker process management
+
+ ```
+ Modify the start_broker.sh script remove the last symbol &
+
+ vim /path/apache_hdfs_broker/bin/start_broker.sh
+ Take this code : nohup $LIMIT $JAVA $JAVA_OPTS org.apache.doris.broker.hdfs.BrokerBootstrap "$@" >> $BROKER_LOG_DIR/apache_hdfs_broker.out 2>&1 </dev/null &
+ Be changed to : nohup $LIMIT $JAVA $JAVA_OPTS org.apache.doris.broker.hdfs.BrokerBootstrap "$@" >> $BROKER_LOG_DIR/apache_hdfs_broker.out 2>&1 </dev/null
+ ```
+
+ Create the supervisor process management profile for the Broker
+
+ ```
+ vim /etc/supervisord.d/doris-broker.ini
+
+ [program:BrokerBootstrap]
+ environment = JAVA_HOME="/usr/local/java"
+ process_name=%(program_name)s
+ directory=/path/apache_hdfs_broker
+ command=sh /path/apache_hdfs_broker/bin/start_broker.sh
+ autostart=true
+ autorestart=true
+ user=root
+ numprocs=1
+ startretries=3
+ stopasgroup=true
+ killasgroup=true
+ startsecs=5
+ #redirect_stderr=true
+ #stdout_logfile_maxbytes=20MB
+ #stdout_logfile_backups=10
+ #stdout_logfile=/var/log/supervisor-BrokerBootstrap.log
+ ```
+
+6. First determine whether the Doris service is stopped, then use supervisor to automatically pull up Doris, and then determine whether the process starts normally
+
+ ```
+ supervisorctl reload # Reload all the Supervisor configuration files
+ supervisorctl status # Check the supervisor status and verify that the Doris service process starts normally
+
+ 其他命令 :
+ supervisorctl start all # supervisorctl start It is capable of opening processes
+ supervisorctl stop doris-be # The process is supervisorctl stop
+ ```
+
+#### Matters needing attention:
+
+- If the supervisor installed using yum starts, an error occurs: pkg_resources.DistributionNotFound: The 'supervisor==3.4.0' distribution was not found
+
+```
+supervisor installed directly using the yum command only supports python2,Therefore, the file contents in /usr/bin/supervisorctl and /usr/bin/supervisorctl should be changed at the beginning Change #! /usr/bin/python to #! /usr/bin/python2, python2 must be installed
+```

+# 服务自动拉起
+
+本文档主要介绍如何配置Doris集群的自动拉起，保证生产环境中出现特殊情况导致服务宕机后未及时拉起服务从而影响到业务的正常运行。
+
+Doris集群必须完全搭建完成后再配置FE和BE的自动拉起服务。
+
+## Systemd配置Doris服务
+
+systemd具体使用以及参数解析可以参考[这里](https://blog.51cto.com/arm2012/1963238)
+
+### sudo 权限控制
+
+在使用 systemd 控制 doris 服务时，需要有 sudo 权限。为了保证最小粒度的 sudo 权限分配，可以将 doris-fe 与 doris-be 服务的 systemd 控制权限分配给指定的非 root 用户。在 visudo 来配置 doris-fe 与 doris-be 的 systemctl 管理权限。
+
+```
+Cmnd_Alias DORISCTL=/usr/bin/systemctl start doris-fe,/usr/bin/systemctl stop doris-fe,/usr/bin/systemctl start doris-be,/usr/bin/systemctl stop doris-be
+
+## Allow root to run any commands anywhere
+root ALL=(ALL) ALL
+doris ALL=(ALL) NOPASSWD:DORISCTL
+```
+
+### 配置步骤
+
+1. 下载doris-fe.service文件: [doris-fe.service](https://github.com/apache/doris/blob/master/tools/systemd/doris-fe.service)
+
+2. doris-fe.service具体内容如下:
+
+ ```

+- ExecStart、ExecStop根据实际部署的fe的路径进行配置
+
+3. 下载doris-be.service文件: [doris-be.service](https://github.com/apache/doris/blob/master/tools/systemd/doris-be.service)
+

+ ```
+
+#### 注意事项
+
+- ExecStart、ExecStop根据实际部署的be的路径进行配置
+
+5. 服务配置
+
+ 将doris-fe.service、doris-be.service两个文件放到 /usr/lib/systemd/system 目录下
+
+6. 设置自启动
+
+ 添加或修改配置文件后，需要重新加载
+
+ ```
+ systemctl daemon-reload
+ ```
+
+ 设置自启动，实质就是在 /etc/systemd/system/multi-user.target.wants/ 添加服务文件的链接
+
+ ```
+ systemctl enable doris-fe
+ systemctl enable doris-be
+ ```
+
+7. 服务启动
+
+ ```
+ systemctl start doris-fe
+ systemctl start doris-be
+ ```
+
+## Supervisor配置Doris服务
+
+Supervisor 具体使用以及参数解析可以参考[这里](http://supervisord.org/)
+
+Supervisor 配置自动拉起可以使用 yum 命令直接安装，也可以通过pip手工安装，pip手工安装流程比较复杂，只展示yum方式部署，手工部署请参考[这里](http://supervisord.org/installing.html)进行安装部署。
+
+### 配置步骤
+
+1. yum安装supervisor
+
+ ```
+ yum install epel-release
+ yum install -y supervisor
+ ```
+
+2. 启动服务并查看状态
+
+ ```
+ systemctl enable supervisord # 开机自启动
+ systemctl start supervisord # 启动supervisord服务
+ systemctl status supervisord # 查看supervisord服务状态
+ ps -ef|grep supervisord # 查看是否存在supervisord进程
+ ```
+
+3. 配置BE进程管理
+
+ ```
+ 修改start_be.sh脚本，去掉最后的 & 符号
+
+ vim /path/doris/be/bin/start_be.sh
+ 将 nohup $LIMIT ${DORIS_HOME}/lib/palo_be "$@" >> $LOG_DIR/be.out 2>&1 </dev/null &
+ 修改为 nohup $LIMIT ${DORIS_HOME}/lib/palo_be "$@" >> $LOG_DIR/be.out 2>&1 </dev/null
+ ```
+
+ 创建 BE 的 supervisor进程管理配置文件
+
+ ```
+ vim /etc/supervisord.d/doris-be.ini
+
+ [program:doris_be]
+ process_name=%(program_name)s
+ directory=/path/doris/be/be
+ command=sh /path/doris/be/bin/start_be.sh
+ autostart=true
+ autorestart=true
+ user=root
+ numprocs=1
+ startretries=3
+ stopasgroup=true
+ killasgroup=true
+ startsecs=5
+ #redirect_stderr = true
+ #stdout_logfile_maxbytes = 20MB
+ #stdout_logfile_backups = 10
+ #stdout_logfile=/var/log/supervisor-palo_be.log
+ ```
+
+4. 配置FE进程管理
+
+ ```
+ 修改start_fe.sh脚本，去掉最后的 & 符号
+
+ vim /path/doris/fe/bin/start_fe.sh
+ 将 nohup $LIMIT $JAVA $final_java_opt org.apache.doris.PaloFe ${HELPER} "$@" >> $LOG_DIR/fe.out 2>&1 </dev/null &
+ 修改为 nohup $LIMIT $JAVA $final_java_opt org.apache.doris.PaloFe ${HELPER} "$@" >> $LOG_DIR/fe.out 2>&1 </dev/null
+ ```
+
+ 创建 FE 的 supervisor进程管理配置文件
+
+ ```
+ vim /etc/supervisord.d/doris-fe.ini
+
+ [program:PaloFe]
+ environment = JAVA_HOME="/path/jdk8"
+ process_name=PaloFe
+ directory=/path/doris/fe
+ command=sh /path/doris/fe/bin/start_fe.sh
+ autostart=true
+ autorestart=true
+ user=root
+ numprocs=1
+ startretries=3
+ stopasgroup=true
+ killasgroup=true
+ startsecs=10
+ #redirect_stderr=true
+ #stdout_logfile_maxbytes=20MB
+ #stdout_logfile_backups=10
+ #stdout_logfile=/var/log/supervisor-PaloFe.log
+ ```
+
+5. 配置Broker进程管理
+
+ ```
+ 修改 start_broker.sh 脚本，去掉最后的 & 符号
+
+ vim /path/apache_hdfs_broker/bin/start_broker.sh
+ 将 nohup $LIMIT $JAVA $JAVA_OPTS org.apache.doris.broker.hdfs.BrokerBootstrap "$@" >> $BROKER_LOG_DIR/apache_hdfs_broker.out 2>&1 </dev/null &
+ 修改为 nohup $LIMIT $JAVA $JAVA_OPTS org.apache.doris.broker.hdfs.BrokerBootstrap "$@" >> $BROKER_LOG_DIR/apache_hdfs_broker.out 2>&1 </dev/null
+ ```
+
+ 创建 Broker 的 supervisor进程管理配置文件
+
+ ```
+ vim /etc/supervisord.d/doris-broker.ini
+
+ [program:BrokerBootstrap]
+ environment = JAVA_HOME="/usr/local/java"
+ process_name=%(program_name)s
+ directory=/path/apache_hdfs_broker
+ command=sh /path/apache_hdfs_broker/bin/start_broker.sh
+ autostart=true
+ autorestart=true
+ user=root
+ numprocs=1
+ startretries=3
+ stopasgroup=true
+ killasgroup=true
+ startsecs=5
+ #redirect_stderr=true
+ #stdout_logfile_maxbytes=20MB
+ #stdout_logfile_backups=10
+ #stdout_logfile=/var/log/supervisor-BrokerBootstrap.log
+ ```
+
+6. 首先确定Doris服务是停止状态，然后使用supervisor将Doris自动拉起，然后确定进程是否正常启动
+
+ ```
+ supervisorctl reload # 重新加载Supervisor中的所有配置文件
+ supervisorctl status # 查看supervisor状态，验证Doris服务进程是否正常启动
+
+ 其他命令 :
+ supervisorctl start all # supervisorctl start 可以开启进程
+ supervisorctl stop doris-be # 通过supervisorctl stop，停止进程
+ ```
+
+#### 注意事项:
+
+- 如果使用 yum 安装的 supervisor 启动报错 : pkg_resources.DistributionNotFound: The 'supervisor==3.4.0' distribution was not found
+
+```
+这个是 python 版本不兼容问题，通过yum命令直接安装的 supervisor 只支持 python2 版本，所以需要将 /usr/bin/supervisord 和 /usr/bin/supervisorctl 中文件内容开头 #!/usr/bin/python 改为 #!/usr/bin/python2 ，前提是要装 python2 版本
+```
