2 zk自启动

路径：/etc/systemd/system

2.1 脚本

[Unit]
Description=zookeeper.service
After=network.target

[Service]
Type=forking
User=root
Group=root
Environment=ZOO_LOG_DIR=/usr/local/zookeeper-3.5.9/bin
Environment=JAVA_HOME=/usr/local/jdk-1.8.0
ExecStart=/usr/local/zookeeper-3.5.9/bin/zkServer.sh start 
ExecStop=/usr/local/zookeeper-3.5.9/bin/zkServer.sh stop
ExecReload=/usr/local/zookeeper-3.5.9/bin/zkServer.sh restart

[Install]
WantedBy=multi-user.target

2.2 添加到自启动

• 刷新配置

systemctl daemon-reload

• zookeeper服务加入开机自启

systemctl enable zookeeper.service

• systemctl启动zookeeper

systemctl start zookeeper.service

• systemctl关闭 zookeeper

systemctl stop  zookeeper.service

• systemctl重启 zookeeper

systemctl  restart  zookeeper.service

3 kafka自启动

3.1 第一种方式

3.1.1 脚本

[Unit]
Description=kafka.service
After=network.target  zookeeper.service

[Service]
Type=forking
User=root
Group=root
Environment=JAVA_HOME=/usr/local/jdk-1.8.0
ExecStart=/usr/local/kafka_2.12-2.4.1/bin/kafka-server-start.sh -daemon  /usr/local/kafka_2.12-2.4.1/config/server.properties
ExecStop=/usr/local/kafka_2.12-2.4.1/bin/kafka-server-stop.sh
Restart=on-failure

[Install]
WantedBy=multi-user.target

注意：是先启动zk后，才可以启动kafka，所以服务kafka添加到zk之后。

3.1.2 添加到自启动

• 刷新配置

systemctl daemon-reload

• kafka服务加入开机自启

systemctl enable kafka.service

• systemctl启动kafka

systemctl start kafka.service

• systemctl关闭kafka

systemctl stop  kafka.service

• systemctl重启 kafka

systemctl  restart  kafka.service

3.2 第二种方式

路径：/etc/init.d/

vim  kafka

3.2.1 脚本

DAEMON_PATH=/opt/kafka/
PATH=$PATH:$DAEMON_PATH/bin

# See how we were called.
case "$1" in
  start)
        # Start daemon.
        echo "Starting Zookeeper";
        nohup $DAEMON_PATH/bin/zookeeper-server-start.sh -daemon /$DAEMON_PATH/config/zookeeper.properties 2> /dev/null && \
        echo "Starting Kafka";
        nohup $DAEMON_PATH/bin/kafka-server-start.sh -daemon /$DAEMON_PATH/config/server.properties 2> /dev/null
        ;;
  stop)
        # Stop daemons.
        echo "Shutting down Zookeeper";
        pid=`ps ax | grep -i 'org.apache.zookeeper.server' | grep -v grep | awk '{print $1}'`
        if [ -n "$pid" ]
          then
          kill -9 $pid
        else
          echo "Zookeeper was not Running"
        fi
        echo "Shutting down Kafka";
        pid=`ps ax | grep -i 'kafka.Kafka' | grep -v grep | awk '{print $1}'`
        if [ -n "$pid" ]
          then
          kill -9 $pid
        else
          echo "Kafka was not Running"
        fi
        ;;
  restart)
        $0 stop
        sleep 2
        $0 start
        ;;
  status)
        pid=`ps ax | grep -i 'org.apache.zookeeper.server' | grep -v grep | awk '{print $1}'`
        if [ -n "$pid" ]
          then
          echo "Zookeeper is Running as PID: $pid"
        else
          echo "Zookeeper is not Running"
        fi
        pid=`ps ax | grep -i 'kafka.Kafka' | grep -v grep | awk '{print $1}'`
        if [ -n "$pid" ]
          then
          echo "Kafka is Running as PID: $pid"
        else
          echo "Kafka is not Running"
        fi
        ;;
  *)
        echo "Usage: $0 {start|stop|restart|status}"
        exit 1
esac

exit 0

3.2.2 设置自启动

• 创建kafka服务

chmod 755 /etc/init.d/kafka
update-rc.d kafka defaults

• 启动和停止kafka服务:

sudo service kafka start
sudo service kafka status
sudo service kafka stop

• 删除Kafka服务,请运行

update-rc.d -f kafka remove

4 cmak自启动

4.1 安装cmake

sudo apt install cmak

cmak -version

后台启动

nohup bin/cmak &

4.2 自启动

4.2.1 创建start.sh

#!/bin/bash
if [ -f RUNNING_PID ];then echo -e "Delete RUNNING_PID !\n";rm RUNNING_PID;fi
/usr/local/cmak-3.0.0.5/bin/cmak   2>&1 >/dev/null &

4.2.2 创建stop.sh

#!/bin/bash
jps|grep -w 'ProdServerStart'|awk '{print $1}'|xargs kill -9
if [ -f RUNNING_PID ];then echo -e "Delete RUNNING_PID!停止cmak 服务\n";rm RUNNING_PID;fi

4.2.3 自启动脚本

Requires=network.target   

[Service]
Type=forking
User=root
Group=root
Environment=JAVA_HOME=/usr/local/jdk-1.8.0
