Centos7：

创建启动脚本frps.sh

#!/bin/sh

nohup ./frps -c frps.ini >/dev/null 2>&1 &

创建任务脚本frps.sh

cd /etc/rc.d/init.d/

#!/bin/sh
#chkconfig: 2345 20 80

cd /root/frp_0.26.0_linux_amd64/
./frps.sh

#添加到任务
chkconfig --add frps.sh
#开机启动
chkconfig frps.sh on

其他方式：

etc/rc.d/rc.local或/etc/rc.local文件，在末尾增加如下内容

su - user -c '/root/frp_0.26.0_linux_amd64/frps.sh'
chmod +x /etc/rc.d/rc.local

OpenWRT/LEDE（编辑/etc/init.d/frp）：

#!/bin/sh /etc/rc.common

START=90
STOP=90
SERVICE=frpc
USE_PROCD=1
PROC="/root/frp/frpc -c /root/frp/frpc.ini"

start_service()

{
    procd_open_instance
    procd_set_param command $PROC
    procd_set_param respawn
    procd_close_instance

}

service_triggers()
{
    procd_add_reload_trigger "rpcd"
}

设置开机启动：

/etc/init.d/frp start
/etc/init.d/frp enable && echo on

OpenWRT natapp启动脚本：
