应用程序部署需要设置开机自启，提供一个启动脚本start.sh，当系统启动时，调用该启动脚本。
在/etc/rc.local文件中，将启动脚本的shell命令加入文本即可。
[root@localhost etc]# cat /etc/rc.local
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.
cd /home/soft
./start.sh
