本次試驗爲squid代理nginx,緩存web網頁的內容
訪問流程如下:
Squid安裝
1.去官網下載安裝包http://www.squid-cache.org/
2.拷貝到服務器上
3.解壓tar -zxf squid-3.3.8.tar.gz
4.編譯安裝
mkdir/usr/local/squid
./configure--prefix=/usr/local/squid/
make &&make install
配置squid
5.增加squid用戶和組
groupadd squid
useradd –g squidsquid
6.修改squid配置文件
vim/usr/local/squid/etc/squid.conf
我的配置文件如下:
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 localnet src fc00::/7 # RFC 4193 local private network range
acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged)machines
acl SSL_ports port 443
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 # https
acl Safe_ports port 70 # gopher
acl Safe_ports port 210 # wais
acl Safe_ports port 1025-65535 # unregistered ports
acl Safe_ports port 280 # http-mgmt
acl Safe_ports port 488 # gss-http
acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
acl CONNECT method CONNECT
http_access deny !Safe_ports
http_access deny CONNECT!SSL_ports

refresh_pattern . 0 20% 4320
cache_effective_user squid
cache_effective_group squid
修改的地方見高亮部分
7.將/usr/local/squid的目錄所有者改爲squid
chown -Rsquid.squid /usr/local/squid/
squid的啓動、重啓
8.啓動 /usr/local/squid/sbin/squid
9.停止/usr/local/squid/sbin/squid -k shutdown
10.重新加載配置文件 /usr/local/squid/sbin/squid-k reconfigure
11.初始化緩存/usr/local/squid/sbin/squid –z
