rc.common 這是做什麼的

原來想在 OPENWRT 安裝 OPENVPN 以及 OPENSSL, 結果FLASH不夠, 參考人家的做法, 開機時下載安裝到RAM DISK, 抄了一個 SHELL SCRIPT, 結果沒動作. 然後看了如何寫 SHELL SCRIPT, 參考這篇, http://linux.vbird.org/linux_bas ... -scripts.php#script,
做了一個 HELLO WORLD 試驗, 應該是OK的

那個沒有動作的SHELL SCRIPT, 抄自此處, 請前輩指點一二,

#!/bin/sh /etc/rc.common
START=99
. /etc/profile
install() {
local OVPNPATH=/tmp/openvpn
local OSSLPATH=/tmp/libopenssl
[ ! -d ${OVPNPATH} ] && mkdir ${OVPNPATH}
[ ! -d ${OSSLPATH} ] && mkdir ${OSSLPATH}
command opkg update || exit 1
# install openvpn
cd ${OVPNPATH}
tar xzf $(opkg download openvpn-openssl |grep Downloaded |cut -d\ -f4 |sed '$s/.$//')
tar xzf data.tar.gz
# delete unnecessary things (save space)
rm -f pkg.tar.gz data.tar.gz control.tar.gz debian-binary getopenvpn.sh
# install libopenssl
cd ${OSSLPATH}
tar xzf $(opkg download libopenssl |grep Downloaded |cut -d\ -f4 |sed '$s/.$//')
tar xzf data.tar.gz
# delete unnecessary things (save space)
rm -f control.tar.gz debian-binary data.tar.gz
}
start () {
# lvl 99 is not enough the script is too
sleep 10 # fast for the install step
install # setup openvpn and libssl
command openvpn --writepid /tmp/openvpn/ovpn.pid --daemon --config /etc/openvpn/client.conf
}
stop() {
PIDOF=$(ps |egrep openvpn |egrep -v grep |awk '{print $1}')
kill ${PIDOF}
}

as long as i can understand, it is a script to "install", "start" and "stop" the openvpn. if you script's name is xyz.sh, you can try
sh xyz.sh install -> to install openvpn
sh xyz.sh start -> to start openvpn
sh xyz.sh stop -> to stop openvpn.

correct me if i am wrong.

沒有動作

即係咩 error ?
估計係
要將個 script 放响 /etc/init.d
响 openwrt 當做一個 service 咁 enable,
boot up 之後, 呢個 service 最後 start
start call install ....
op 有冇, set +x mode

當做 trial run under current dir.
就咁 ./Your_script_name.xxx start
應該就 download, install, run service.

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/tmp/libopenssl/lib
export PATH=$PATH:/tmp/openvpn/bin

有冇加到個 path 去 /etc/profile

i don't think there is any error since you are not actually "asking" to do something.

回覆 3# cal22cal

OpenWRT 改版了, 下載安裝後, 每條PATH都多了 /usr/. 例如, libopenssl/usr/lib, 修改後就好了.
但是另外一個問題來了, 因為放在 /etc/init.d/, 開機時可以自動啟動, PS 看看PID, 有這個SERVICE存在, 不過沒有在這個 SCRIPT 處理密碼帳號的, 所以只有啟動, 實際上沒辦法連接 VPN SERVER, 要怎樣解決呢.

另外, 完全手動,
