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

[root@docker opt]# cat tech_doc/tech_doc
#!/bin/sh

   b=''

   while [ $i -le 100 ]
   do
       printf "$1:[%-50s]%d%%\r" $b $i
       sleep 0.3
       i=`expr 2 + $i`
       b=#$b
   done
   echo
}

function svcStart()
{
   echo "Starting $2 ..."
   cd $1
   PID=$(ps -ef | grep "$4" | grep -v grep | awk '{print $2}')
   if [ -z "$PID" ]; then
       nohup java -jar $3 > $5 2> $6 &
       serviceLoad $SERVICE_NAME
       echo "$2 started ..."
   else
       echo "$2 is already running ..."

   if [ -z "$PID" ]; then
       echo "$2 already stopped ..."
   else
       kill $PID
       echo "$2 is stoping ..."
   fi
}

function do_start()
{
   for FILE in `ls $HOME | grep jar`
   do
       FILE_NAME=$FILE
       SERVICE_JAR_PACKAGE_PATH=$HOME/$FILE
       SERVICE_NAME=${FILE_NAME%-[0-9]*}
       SERVICE_LOG_PATH="$LOGHOME/$SERVICE_NAME.log"
       SERVICE_ERR_LOG_PATH="$LOGHOME/$SERVICE_NAME.err"
       svcStart $HOME $SERVICE_NAME $SERVICE_JAR_PACKAGE_PATH $FILE_NAME $SERVICE_LOG_PATH $SERVICE_ERR_LOG_PATH

case "$1" in

       ;;
   stop)
       do_stop
       echo stop successful
       ;;
   restart)
       do_stop

   *)
       echo "Usage: {start|stop|restart|status}" >&2
       exit 3
       ;;
esac
exit 0

制作服务

在 init.d 下创建服务：

[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

tech-doc 内容如下：

[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
