最新的OPENWRT与FRPC不兼容问题

applebomb2026-04-22 14:47

最新的openwrt （04.21.2026）如果使用编译添加了frpc，启动会报错：

bash 复制代码 
frp服务启动失败，请检查服务端 "TCP多路复用(tcp_mux)"设置，确保与客户端完全一致！

不要被这个坑爹的提示误导了。它的实际意义是：

frpc进程没有在运行，而已！

究其原因，是因为启动脚本一个字没变，但是最新的服务启动停止命令变成start-stop-daemon了！

于是乎启动服务脚本失效了！

解决办法，就是修改/etc/init.d/frp这个服务，修改为以下内容：

bash 复制代码 
#!/bin/sh /etc/rc.common

START=99

LOGFILE="/var/etc/frp/frpc.log"

echo_date(){
        local log=$1
        echo $(date +%Y/%m/%d\ %X): "$log" >> $LOGFILE
}

Reduce_Log(){
        local log=$1
        [ ! -f "$log" ] && return
        local sc=200
        [ -n "$2" ] && sc=$2
        local count=$(grep -c "" $log)
        if [ $count -gt $sc ];then
                let count=count-$sc
                sed -i "1,$count d" $log
        fi
}
