• Squid 反向代理配置


    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
    反向代理/单个添加IP
    # 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 服务器IP 端口 originserver代理该服务端所有域名
    cache_peer 61.135.169.125 parent 80 0 originserver
    # 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
    反向代理/单服务器上所有IP

    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
