Ubuntu 18.04不能像之前的版本那样直接通过编辑rc.local文件来设置开机启动脚本，不过，通过如下的配置，可以让rc.local重新发挥作用。

1. 建立rc-local.service文件

sudo vi /etc/systemd/system/rc-local.service

2. 将下列内容复制并粘贴进rc-local.service文件

[Unit]
Description=/etc/rc.local Compatibility
ConditionPathExists=/etc/rc.local
 
[Service]
Type=forking
ExecStart=/etc/rc.local start
TimeoutSec=0
StandardOutput=tty
RemainAfterExit=yes
SysVStartPriority=99
 
[Install]
WantedBy=multi-user.target

3. 创建文件 rc.local

sudo vi /etc/rc.local

4. 将下列内容复制并粘贴进rc.local 文件

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
sleep 30
cd /home/vagrant/code/kttCRM/ && /usr/bin/php artisan gateway-worker:server start --daemon
exit 0

在这个文件里，把开机执行的脚本放在exit 0的上面。需要注意，sleep 30表示在执行脚本之前等待30秒钟的时间，以确保PHP启动完毕，否则会出现无法执行命令的情况，可以适当延长等待的时间。

补充：针对docker的环境，在docker-compose exec命令中加入-T选项，开启tty。

cd /home/crm/kttCRM && sudo docker-compose exec -T app /usr/local/bin/php artisan gateway-worker:server start --daemon

5. 给rc.local文件加上可执行权限

sudo chmod +x /etc/rc.local

6. 启动服务

sudo systemctl enable rc-local

7. 启动服务并检查状态

sudo systemctl start rc-local.service
sudo systemctl status rc-local.service

可以看到以下的输出说明已成功启动Workerman、GatewayWorker服务进程：

vagrant@homestead:/etc$ sudo systemctl status rc-local.service

至此，可以重启服务器，会看到服务已经自动启动了。
