求助squid+apache,详细配置说明

luo118

小弟初始接触 squid  听说这代理可以加速动态网页,并可以解决apache的负载问题,

在网上收集了不少资料, 但是今天配置了一下,尝未成功. 所以请各位朋友帮助,或给个详细的配置方法,谢谢!

我的版本配置方法如下

squid-2.6.STABLE16-1.fc7

httpd-2.2.4-4.1.fc7

httpd.conf 端口有80改为8080 测试正常, 所以apache 没有问题,

squid.conf 配置如下

squid -z 没有错误,
service squid restart 重启没有错误,

好了到IE浏览器 输入 http://192.168.18.199 时候出现如下错误

这证明了squid 起到了作用,但是为什么打不开里面的网站内容

如输入 http://192.168.18.199:8080 即正常,因为这是直接连接到apache 服务里,并没用到代理,

所以请各位帮忙一下,

还有一点,如果加上如下,
httpd_accel_host 127.0.0.1
httpd_accel_port 8080                   #apache的端口
httpd_accel_single_host on
httpd_accel_with_proxy on          #启用缓存
httpd_accel_uses_host_header on #启用虚拟主机支持
说没有httpd_accel这语法, 但是在squid 2.5测试一下,这是OK的,不知道是不是版本问题,

没有人回自已顶上:wink:

你看下日志，先确定squid有没有向源web服务器请求数据。

好明天上班再测试一下, 请问你有没有配置过, 如果配置过,能问分享一下.

我的版本配置方法如 ...

是否做了对apahce8080端口的访问跳转到squid 80端口访问的设置
例如iptables -t nat -A PREROUTING -i eth0 -p tcp -m tcp --dport 8080 -j REDIRECT --to-ports 80
具体可根据自己情况来定

luo118

楼上, 我上面直接用了80端口给了squid用了,应不用NAT转换了吧!
因为我根本没有8080访问的,只是测试,
80已经给squid用了,所以不用做NAT转换,

除非apache用80 squid用8080 那么NAT为
iptables -t nat -A PREROUTING -i eth0 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 8080
