Apache ProxyPass 出现503 Service Temporarily Unavailable
在CentOS上配置Apache和Tomcat整合，因为之前windows已经配置好，所以httpd.conf就直接复制代码上去了。发现一直报错。<VirtualHost *:80> #域名 ServerName amap.jww.cn #DocumentRoot /var/www/catlog ErrorLog "/var/www/catlog/error.log" CustomLog "/var/www/catlog/common.log" common #反向代理Begin ProxyPass /images !
