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 !
    ProxyPass /css !
    ProxyPass /js !
    #可多对
    ProxyPass / http://127.0.0.1:8080/
    ProxyPassReverse / http://127.0.0.1:8080/
    #反向代理END
</VirtualHost>

查看日志发现报错

问渡娘后得知是是SELinux的原因，httpd不能防问网络[code="shell"]# /usr/sbin/getsebool -a |grep httpd_can_network_connect
httpd_can_network_connect --> off
httpd_can_network_connect_cobbler --> off
httpd_can_network_connect_db --> off
#[/code]更改SELinux设置[code="shell"]# /usr/sbin/setsebool -P httpd_can_network_connect=1
# /usr/sbin/getsebool -a |grep httpd_can_network_connect
httpd_can_network_connect --> on
httpd_can_network_connect_cobbler --> off
httpd_can_network_connect_db --> off
#
[/code]另外关掉SELinux也是可以解决这个问题
修改/etc/selinux/config 然后重启：[quote]SELINUX=disabled[/quote]
或者实时生效的方式：[quote]# /usr/sbin/setenforce 0[/quote]
