Linux - Linux创建自建服务

以打包自己开发的Java应用到Linux服务器,作为一个服务启动,并开启自启。 @pdai

文件准备

[root@docker opt]# tree -a
.
└── tech_doc
    ├── bin
    │   ├── logs
    │   │   └── service.2018-10-31.log
    │   └── tech_arch-0.0.1-RELEASE.jar
    └── tech_doc

创建启动文件

制作服务

在init.d下创建服务

[root@docker init.d]# tree -a
.
├── functions
├── netconsole
├── network
├── README
└── tech-doc

tech-doc内容如下:

[root@docker opt]# cd /etc/init.d
[root@docker init.d]# ls
functions  netconsole  network  README  tech-doc
[root@docker init.d]# tree -a
.
├── functions
├── netconsole
├── network
├── README
└── tech-doc

0 directories, 5 files
[root@docker init.d]# ^C
[root@docker init.d]# cat tech-doc
#!/bin/sh
#
# /etc/init.d/tech-doc
# chkconfig: 2345 60 20
# description: ms.
# processname: tech-doc

SCRIPT_HOME=/opt/tech_doc

case $1 in
    start)
        sh $SCRIPT_HOME/tech_doc start
    ;;
    stop)
        sh $SCRIPT_HOME/tech_doc stop
    ;;
    restart)
        sh $SCRIPT_HOME/tech_doc stop
        sh $SCRIPT_HOME/tech_doc start
    ;;
    status)
        sh $SCRIPT_HOME/tech_doc status
    ;;
    *)
    echo "Usage: {start|stop|restart|status}" >&2
    exit 3
    ;;
esac
exit 0

赋予权限

chmod 777 /etc/init.d/tech-doc

开机自启

chkconfig --list
chkconfig tech-doc on

查看端口

netstat -nltp

查看防火墙

systemctl status firewalld
