私有预渲染服务器和angular js问题

如何解决私有预渲染服务器和angular js问题

您好，我正在使用开源预渲染中间件，因为我将其安装在CentOS 7服务器上，如下所示：

 git clone https://github.com/prerender/prerender.git
 cd prerender
 npm install

我在server.js文件中使用的配置非常简单：

var prerender = require('./lib');

var server = prerender({
        chromeLocation: '/usr/bin/google-chrome-stable',chromeFlags: ['--no-sandbox','--headless','--disable-gpu','--remote-debugging-port=9222','--hide-scrollbars','--disable-setuid-
sandbox' ]

});



server.use(prerender.sendPrerenderHeader());
// server.use(prerender.blockResources());
server.use(prerender.removeScriptTags());
server.use(prerender.httpHeaders());
server.use(require('prerender-memory-cache'))



server.start();

我还将prerender-apache中间件与prerender和angular js应用程序一起使用

    RequestHeader set X-Prerender-Token "token"

     <IfModule mod_proxy_http.c>
   
        RewriteCond %{REQUEST_FILENAME} !-f
        RewriteCond %{REQUEST_FILENAME} !-d
        RewriteCond %{HTTP_USER_AGENT} Googlebot|Sitemaps|Google-Structured-Data-Testing-Tool|baiduspider|facebookexternalhit|twitterbot|rogerbot|linkedinbot|embedly|quora\ link\ preview|showyoubot|outbrain|pinterest|slackbot|vkShare|W3C_Validator [NC,OR]
        RewriteCond %{QUERY_STRING} _escaped_fragment_
        RewriteCond %{REQUEST_URI} /(.*)/(.*)/
        
        # Only proxy the request to Prerender if it's a request for HTML

            RewriteRule ^(?!.*?(\.js|\.css|\.xml|\.less|\.png|\.jpg|\.jpeg|\.gif|\.pdf|\.doc|\.txt|\.ico|\.rss|\.zip|\.mp3|\.rar|\.exe|\.wmv|\.doc|\.avi|\.ppt|\.mpg|\.mpeg|\.tif|\.wav|\.mov|\.psd|\.ai|\.xls|\.mp4|\.m4a|\.swf|\.dat|\.dmg|\.iso|\.flv|\.m4v|\.torrent|\.ttf|\.woff))(.*)  http://some.ip:3000/https://%{HTTP_HOST}/$2 [P,L]

        #RewriteRule ^(.*)  http:/some.ip:3000/https://%{HTTP_HOST} [P,L]


    </IfModule>

所以首先，我尝试在prerender文件夹中使用以下命令使用forever.js运行它：

forever start server.js

它可以正常工作几个小时，然后出现一个问题，我不知道为什么会发生。开始创建许多chrome会话，并且服务器RAM开始减少，直到服务器停止，我读到该标志：'--no-sandbox导致此问题，我已将其删除，但是启动服务器时又遇到了另一个问题我永远拥有.js：

Starting Prerender
Starting Chrome
Prerender server accepting requests on port 3000
Chrome connection closed... restarting Chrome
Chrome died immediately after restart... stopping Prerender
error: Forever detected script exited with code: 0

我正在使用

node.js v12.14.0
Google Chrome 85.0.4183.102

如果有人可以帮助我，我将不胜感激。
