Squid 反向代理配置
1、删除主配置文件重写写入配置
rm -f /etc/squid/squid.conf
2、重新写入配置反向代理
vim /etc/squid/squid.conf
# 监听端口 # 修改端口80 accel vhost vport 为反向代理 http_port 80 accel vhost vport # cache_peer 代理IP 端口 0 originserver name=a "a"代表一个域名 cache_peer 123.125.119.147 parent 80 0 originserver name=a cache_peer 61.135.169.125 parent 80 0 originserver name=b # 设置a的域名为 www.qq.com cache_peer_domain a www.qq.com cache_peer_domain b www.baidu.com # acl权限控制 acl manager proto cache_object acl localhost src 127.0.0.1/32 ::1 acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 acl localnet src 10.0.0.0/8 # RFC1918 possible internal network acl localnet src 172.16.0.0/12 # RFC1918 possible internal network acl localnet src 192.168.0.0/16 # RFC1918 possible internal network acl SSL_ports port 443 acl Safe_ports port 80 8080 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl CONNECT method CONNECT http_access allow manager localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow localnet http_access allow localhost http_access allow all # 缓存文件格式 aufs 缓存路径 目录1024大小MB 16子目录 256子子目录 cache_dir aufs /data/cache 1024 16 256 # 内存占用大小 cache_mem 128 MB hierarchy_stoplist cgi-bin ? coredump_dir /var/spool/squid # 以某个字符开头的进行缓存缓存10080秒 refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 # 以某个字符结尾的进行缓存 缓存2880秒 refresh_pattern \.(jpg|png|gif|mp3|xml) 1440 50% 2880 ignore-reload refresh_pattern . 0 20% 4320

3、查看语法是否有错
squid -kcheck
报错4、添加目录权限
# 创建缓存目录 mkdir /data/cache # 该目录赋予squid用户所属权限 chown -R squid:squid /data/cache/ # 初始化目录 squid -z
5、重启服务
/etc/init.d/squid stop /etc/init.d/squid start
6、查看启动情况
查看启动进程Squid 反向代理测试
1、访问未代理域名，503错误
curl -xlocalhost:80 www.qqfdsfds.com -I HTTP/1.0 503 Service Unavailable
2、访问已代理域名，200正常
curl -xlocalhost:80 www.baidu.com -I HTTP/1.0 200 OK
