类似于s6，不过runit在openwrt busybox中自带，需编译openwrt固件时选择。
runsvdir用以扫描指定目录子目录下run脚本并使用runsv启动为守护进程：

runsvdir -P /etc/config/service/

一个openconnect启动脚本示例，注意启动的程序一定要以非守护进程启动且以exec命令执行：

cat /etc/config/service/openconnect/run 
exec 2>&1
exec openconnect -c user-cert.pem -k user-key.pem -s /etc/config/vpnc --no-cert-check www.haiyun.me

如果run目录存在finish脚本，run执行的程序退出后runsv会执行finish并传递程序退出code给finish参数1，然后再重新执行run启动程序，我们可以使用finish判断当网络不通时程序退出状态，避免程序持续启动退出导致死循环：

#!/bin/sh
if [ $1 -eq 255 ]
then
  sleep 5
else
  exit
fi

控制启动的程序，更多见http://smarden.org/runit/sv.8.html：

sv status /etc/config/service/openconnect/
sv stop /etc/config/service/openconnect/
sv start /etc/config/service/openconnect/
sv restart /etc/config/service/openconnect/

也可以用runit管理ssh动态隧道转发实现类似于autossh的功能，ssh连接时使用超时控制，超时后ssh关闭runsv会自动重启ssh。

首先安装GO环境，https://www.haiyun.me/archives/1009.html

cd /usr/local/src/
git clone https://github.com/inconshreveable/ngrok.git
export GOPATH=/usr/local/src/ngrok/
export NGROK_DOMAIN="haiyun.me"

生成自签名SSL证书，ngrok为ssl加密连接：

cd ngrok
openssl genrsa -out rootCA.key 2048
openssl req -x509 -new -nodes -key rootCA.key -subj "/CN=$NGROK_DOMAIN" -days 5000 -out rootCA.pem
openssl genrsa -out device.key 2048
openssl req -new -key device.key -subj "/CN=$NGROK_DOMAIN" -out device.csr
openssl x509 -req -in device.csr -CA rootCA.pem -CAkey rootCA.key -CAcreateserial -out device.crt -days 5000
cp rootCA.pem assets/client/tls/ngrokroot.crt
cp device.crt assets/server/tls/snakeoil.crt 
cp device.key assets/server/tls/snakeoil.key
GOOS=linux GOARCH=386
make clean
make release-server release-client

如果一直停留在go get gopkg.in/yaml.v1参考：https://www.haiyun.me/archives/1011.html
启动SERVER：

bin/ngrokd -domain="$NGROK_DOMAIN" -httpAddr=":8000" 

交叉编译windows客户端，最好安装最新版本Golang，使用yum安装的一直编译不通过。

cd /usr/local/go/src/
GOOS=windows GOARCH=386 CGO_ENABLED=0 ./make.bash
cd -
GOOS=windows GOARCH=386 make release-server release-client

客户端配置：

server_addr: "haiyun.me:4443"
trust_host_root_certs: false
tunnels:
  http:
    subdomain: "example"
    auth: "user:12345"
    proto:
      http: "80"

  ssh:
    remote_port: 2222
    proto:
      tcp: "22"

启动客户端：

bin/ngrok -config ngrok.conf start http ssh

注意所有domain要一致，不然会出现证书错误：

Failed to read message: remote error: bad certificate

SSH默认转发远程服务器端口时监听loop，只能通过本地访问端口，如：

ssh -R 0.0.0.0:9022:localhost:22 root@haiyun.me

修改配置文件允许自定义监听地址：

echo 'GatewayPorts yes' >> /etc/ssh/sshd_config 
/etc/init.d/sshd restart

通过ngrok服务器转发端口到本地80：

ngrok 80

自定义二级域名，需在ngrok官网注册账号获取auth token：

ngrok -authtoken Co1KiaaAdpapgD -subdomain=example 80

转发TCP协议其它端口，

ngrok -authtoken Co1KiaaAdpapgD -proto=tcp 22

指定远程服务器端口：

auth_token: Co1KiaaAdpapgD
tunnels:
  ssh:
    proto:
      tcp: "22"
    remote_port: 52222

启动：

ngrok -config ngrok.conf start ssh

通过composer安装php-webdriver：

apt install php7.4-cli php-curl php-zip
curl -sS https://getcomposer.org/installer | php --install-dir=/usr/bin/
php composer.phar require php-webdriver/webdriver 

安装java环境和selenium server：

apt install openjdk-14-jre
wget https://selenium-release.storage.googleapis.com/3.141/selenium-server-standalone-3.141.59.jar
java -jar selenium-server-standalone-3.141.59.jar 

安装firefox/chrome浏览器和相应的webdirver：

wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
apt install ./google-chrome-stable_current_amd64.deb 
wget https://chromedriver.storage.googleapis.com/88.0.4324.96/chromedriver_linux64.zip
unzip chromedriver_linux64.zip 
mv chromedriver /usr/bin/
apt install firefox
wget https://github.com/mozilla/geckodriver/releases/download/v0.29.0/geckodriver-v0.29.0-linux64.tar.gz
tar zxf geckodriver-v0.29.0-linux64.tar.gz 
mv geckodriver /usr/bin/

启动浏览器需X环境支持，可使用XVNC或X Window
可以使用Firefox扩展Selenium IDE: PHP Formatters录制脚本。
selenium chrome使用：

<?php
require_once('vendor/autoload.php');
use Facebook\WebDriver\Remote\DesiredCapabilities;
use Facebook\WebDriver\Remote\RemoteWebDriver;
use Facebook\WebDriver\Chrome\ChromeOptions;

$host = 'http://localhost:4444/wd/hub';
$options = new ChromeOptions();
$options->addArguments(array(
        '--no-sandbox',
        '--headless',
        '--start-maximized',
        '--user-data-dir=/tmp/chrome-user-data-dir',
        '--profile-directory=/tmp/chrome-profile-dir',
        '--user-agent=Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.182 Safari/537.36'
));
$caps = DesiredCapabilities::chrome();
$caps->setCapability(ChromeOptions::CAPABILITY, $options);
$driver = RemoteWebDriver::create($host, $caps);
//default
//$driver = RemoteWebDriver::create($host, DesiredCapabilities::chrome());
//$driver->manage()->window()->maximize();
$driver->get('https://www.haiyun.me/');
var_dump($driver->getTitle());
$driver->quit();

selenium firefox使用：

<?php
namespace Facebook\WebDriver;
require 'vendor/autoload.php';
use Facebook\WebDriver\Remote\RemoteWebDriver;
use Facebook\WebDriver\Remote\DesiredCapabilities;
use Facebook\WebDriver\Firefox\FirefoxProfile;
use Facebook\WebDriver\Firefox\FirefoxDriver;

$host = 'http://localhost:4444/wd/hub';
$profile = new FirefoxProfile();
$profile->setPreference('browser.startup.homepage', 'https://github.com/facebook/php-webdriver/');
$profile->setPreference("general.useragent.override", "Mozilla/5.0");
//$profile->addExtension('./vimperator-3.8.2-fx.xpi');
$caps = DesiredCapabilities::firefox(); 
$caps->setCapability(FirefoxDriver::PROFILE, $profile); 
$caps->setCapability('moz:firefoxOptions', ['args' => ['-headless']]);
$caps->setCapability('moz:firefoxOptions', ['args' => ["-profile", "/tmp/firefox_profile"]]);
$driver = RemoteWebDriver::create($host, $caps);

//default
//$driver = RemoteWebDriver::create($host, DesiredCapabilities::firefox());
$driver->manage()->window()->maximize();
$driver->get('https://www.haiyun.me/');
var_dump($driver->getTitle());
$driver->quit();
