503服务不可用。 Apache在7-10天内崩溃一次

我在Ubuntu 14.04上使用Apache服务器。为了将mypage.com的所有请求重定向到mypage.com:8080/myapp，我使用了mod_proxy。我的000-default.conf如下所示：503服务不可用。 Apache在7-10天内崩溃一次

<VirtualHost *:80> 
    # The ServerName directive sets the request scheme, hostname and port that 
    # the server uses to identify itself. This is used when creating 
    # redirection URLs. In the context of virtual hosts, the ServerName 
    # specifies what hostname must appear in the request's Host: header to 
    # match this virtual host. For the default virtual host (this file) this 
    # value is not decisive as it is used as a last resort host regardless. 
    # However, you must set it for any further virtual host explicitly. 
    #ServerName www.example.com 

    ServerAdmin [email protected] 
    DocumentRoot /var/www/html 

    # Available loglevels: trace8, ..., trace1, debug, info, notice, warn, 
    # error, crit, alert, emerg. 
    # It is also possible to configure the loglevel for particular 
    # modules, e.g. 
    #LogLevel info ssl:warn 

    ErrorLog ${APACHE_LOG_DIR}/error.log 
    CustomLog ${APACHE_LOG_DIR}/access.log combined 
    ProxyPass/http://mypage.com:8080/myapp/ retry=0 timeout=10 
    ProxyPassReverse/http://mypage.com:8080/myapp/ 

    ServerName mypage.com 

    # For most configuration files from conf-available/, which are 
    # enabled or disabled at a global level, it is possible to 
    # include a line for only one particular virtual host. For example the 
    # following line enables the CGI configuration for this host only 
    # after it has been globally disabled with "a2disconf". 
    #Include conf-available/serve-cgi-bin.conf 
</VirtualHost>

这就是我的ports.conf

# If you just change the port or add more ports here, you will likely also 
# have to change the VirtualHost statement in 
# /etc/apache2/sites-enabled/000-default.conf 

Listen 80 
Listen 81 

<IfModule ssl_module> 
    Listen 443 
</IfModule> 

<IfModule mod_gnutls.c> 
    Listen 443 
</IfModule> 

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

，一切工作正常，直到在几天我总是得到503服务不可用错误页面。和我重新启动我的机器再次工作正常后发生

之前的错误，这是写在error.log中。然后在7-10天内再次崩溃。在互联网上尝试了很多东西，但在几周内最多会出现这个错误。已经持续了几个月。 SELinux被禁用。

问题不在于与Apache，因为它仍然服503页

问题是与端口号8080上运行的应用程序，你是反向代理/到http://mypage.com:8080/myapp/当阿帕奇试图代理请求其没有收回来自8080应用程序的响应，因此它放弃了“服务不可用”消息。它从日志的基础部分推断出来。

因此，检查和后（如有必要）端口号运行8080

谢谢您response.On 8080作品Tomcat服务器中部署Java application.Which日志文件是否必须检查服务器的日志？也有一些是在可疑catalina.out的 '2015年10月25日上午7时49分23秒org.apache.catalina.realm.LockOutRealm认证警告：试图以验证锁定的用户“admin”的 10月25日， 2015 7:49:24 AM org.apache.catalina.realm.LockOutRealm进行身份验证警告：尝试对用户“admin”进行身份验证不知道它是否与我的问题有任何关系。还有你认为，关于事实，大多数工作正常，直到它崩溃后约一周 – FarizHuseynli

看起来像有人试图暴力进入应用程序，检查此线程http://stackoverflow.com/questions/15337296/how -to-fix-tomcat-warning-an-attempt-was-made-to-authenticate-the-locked-user – Shiva

你认为503错误可能是因为这个原因而发生的吗？ – FarizHuseynli

503服务不可用。 Apache在7-10天内崩溃一次
