我曾尝试通过 HTTP 从 socketme.io 连接 PHP WebSocket，虽然成功了，但再次加载证书并建立 HTTPS 后却无法工作。
由于我的托管服务器的 nginx 配置为在代理模式下工作
当网站 URL 在浏览器中打开时，基本上会发生以下情况：
客户端请求到达前端 Nginx，请求获取一些资源（.html 页面、.php 页面、图像、javascript 等）。我们托管服务器中的 Nginx 在 TCP 端口上运行：80 - http、443 - https。
Nginx 检查其缓存中是否已有该资源。
如果资源被缓存，Nginx 将返回缓存的内容。
如果资源未缓存或请求动态页面（例如 index.php），Nginx 会将请求代理（转发）到后端服务器 - Apache。我们托管服务器中的 Apache 在 TCP 端口上运行：7080 - http，7081 - https。然后 Nginx 缓存静态内容 - HTML、图像、js、css。
Nginx 在端口 80 上监听传入连接并处理 SSL。Nginx 会将传入连接转发到您常规网站的 PHP-FPM，如果它检测到连接是 WebSocket 连接，则将连接代理到端口 8080 上正在运行的 Ratchet 应用程序，然后 javascript 就可以通过 wss:/my.domain.com 进行连接
通过浏览器进行安慰
var conn = new WebSocket('wss://my.domain.com:8080');
conn.onopen = function(e) {
console.log("Connection established!");
};
conn.onmessage = function(e) {
console.log(e.data);
};
WebSocket 连接‘wss://my.domain.com:8080/’失败：WebSocket 打开握手超时
wss://my.domain.com:8080/wss WebSocket 连接到 'wss://my.domain.com:8080/wss' 失败：WebSocket 打开握手超时
wss://my.domain.com:8080/websocket WebSocket 连接到 'wss://my.domain.com:8080/websocket' 失败：WebSocket 打开握手超时
wss://my.domain.com/websocket:8080 WebSocket 连接‘wss://my.domain.com/websocket:8080’失败：建立连接时出错：net::ERR_CERT_AUTHORITY_INVALID
wss://my.domain.com/wss:8080 WebSocket 连接‘wss://my.domain.com/wss:8080’失败：建立连接时出错：net::ERR_CERT_AUTHORITY_INVALID
jQuery(function($){ // Websocket_Controller var websocket_server = new WebSocket("wss://my.domain.com:8080"); websocket_server.onopen = function(e) { websocket_server.send( ... ); }; websocket_server.onerror = function(e) { // Errorhandling ... } websocket_server.onmessage = function(e) { ... } }

/etc/apache2/apache2.conf
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.4/ for detailed information about
# the directives and /usr/share/doc/apache2/README.Debian about Debian specific
# hints.
#
#
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.
# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#
# /etc/apache2/
# |-- apache2.conf
# | `-- ports.conf
# |-- mods-enabled
# | |-- *.load
# | `-- *.conf
# |-- conf-enabled
# | `-- *.conf
# `-- sites-enabled
# `-- *.conf
#
#
# * apache2.conf is the main configuration file (this file). It puts the pieces
# together by including all remaining configuration files when starting up the
# web server.
#
# * ports.conf is always included from the main configuration file. It is
# supposed to determine listening ports for incoming connections which can be
# customized anytime.
#
# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
# directories contain particular configuration snippets which manage modules,
# global configuration fragments, or virtual host configurations,
# respectively.
#
# They are activated by symlinking available configuration files from their
# respective *-available/ counterparts. These should be managed by using our
# helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
# their respective man pages for detailed information.
#
# * The binary is called apache2. Due to the use of environment variables, in
# the default configuration, apache2 needs to be started/stopped with
# /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
# work with the default configuration.
# Global configuration
#
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the Mutex documentation (available
# at <URL:http://httpd.apache.org/docs/2.4/mod/core.html#mutex>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
#ServerRoot "/etc/apache2"
#
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
#
Mutex file:${APACHE_LOCK_DIR} default
#
# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#
PidFile ${APACHE_PID_FILE}
#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300
#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On
#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100
#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 5
# These need to be set in /etc/apache2/envvars
User ${APACHE_RUN_USER}
Group ${APACHE_RUN_GROUP}
#
# HostnameLookups: Log the names of clients or just their IP addresses
# e.g., www.apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
#
HostnameLookups Off
# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be
# logged here. If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.
#
ErrorLog ${APACHE_LOG_DIR}/error.log
#
# LogLevel: Control the severity of messages logged to the error_log.
# Available values: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the log level for particular modules, e.g.
# "LogLevel info ssl:warn"
#
LogLevel warn

# Sets the default security model of the Apache2 HTTPD server. It does
# not allow access to the root filesystem outside of /usr/share and /var/www.
# The former is used by web applications packaged in Debian,
# the latter may be used for local directories served by the web server. If
# your system is serving content from a sub-directory in /srv you must allow
# access here, or in any related virtual host.

我曾尝试通过配置nginx.conf，但仍然没有用，而且我也proxy_pass没有httpd.confapache2.conf
我应该如何修改，需要修改哪些配置文件才能正常工作？
