Linux - Linux创建自建服务

提示

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。

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
