systemd 服务管理编写

1.编辑服务管理脚本

$ cat /lib/systemd/system/kafka.service
[Unit]
Description=Kafka Server
Documentation=https://prometheus.io/docs/introduction/overview/
After=network.target

[Service]
# 启动用户
User=user00
# 启动组
Group=user00
# 失败后，是否重启
#Restart=on-failure
# 工做目录
WorkingDirectory=/data/home/user00/kafka_2.11-2.0.1
# 环境变量
Environment=KAFKA_HEAP_OPTS=-Xms8g -Xmx8g
Environment=JAVA_HOME=/usr/java/jdk1.8.0_191
Environment=CLASSPATH=.:/lib.tools.jar
Environment=${JAVA_HOME}/bin:${PATH}:/data/home/user00/aspnetcor
# 启动/关闭超时时间，超事后就强制关闭
TimeoutSec=30
# 启动命令，必须是前台启动进程
ExecStart=/data/home/user00/kafka_2.11-2.0.1/bin/kafka-server-start.sh /data/home/user00/kafka_2.11-2.0.1/config/server.properties
# 中止命令
ExecStop=/data/home/user00/kafka_2.11-2.0.1/bin/kafka-server-stop.sh /data/home/user00/kafka_2.11-2.0.1/config/server.properties

[Install]
WantedBy=multi-user.target

文件必须以.service结尾

2.刷新配置启动脚本

$ systemctl daemon-reload

3.启动服务，而且设置开机自启
