503服務不可用。 Apache在7-10天內崩潰一次

我在Ubuntu 14.04上使用Apache服務器。爲了將mypage.com的所有請求重定向到mypage.com:8080/myapp，我使用了mod_proxy。我的000-default.conf如下所示：503服務不可用。 Apache在7-10天內崩潰一次

<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>

這就是我的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，直到在幾天我總是得到503服務不可用錯誤頁面。和我重新啓動我的機器再次工作正常後發生

之前的錯誤，這是寫在error.log中。然後在7-10天內再次崩潰。在互聯網上嘗試了很多東西，但在幾周內最多會出現這個錯誤。已經持續了幾個月。 SELinux被禁用。

問題不在於與Apache，因爲它仍然服503頁

問題是與端口號8080上運行的應用程序，你是反向代理/到http://mypage.com:8080/myapp/當阿帕奇試圖代理請求其沒有收回來自8080應用程序的響應，因此它放棄了「服務不可用」消息。它從日誌的基礎部分推斷出來。

因此，檢查和後（如有必要）端口號運行8080

謝謝您response.On 8080作品Tomcat服務器中部署Java application.Which日誌文件是否必須檢查服務器的日誌？也有一些是在可疑catalina.out的 '2015年10月25日上午7時49分23秒org.apache.catalina.realm.LockOutRealm認證警告：試圖以驗證鎖定的用戶「admin」的 10月25日， 2015 7:49:24 AM org.apache.catalina.realm.LockOutRealm進行身份驗證警告：嘗試對用戶「admin」進行身份驗證不知道它是否與我的問題有任何關係。還有你認爲，關於事實，大多數工作正常，直到它崩潰後約一週 – FarizHuseynli

看起來像有人試圖暴力進入應用程序，檢查此線程http://stackoverflow.com/questions/15337296/how -to-fix-tomcat-warning-an-attempt-was-made-to-authenticate-the-locked-user – Shiva

你認爲503錯誤可能是因爲這個原因而發生的嗎？ – FarizHuseynli

503服務不可用。 Apache在7-10天內崩潰一次
