squid

测试平台:    Redhat linux7.2      squid-2.5.STABLE2
# cd /usr/local/squid/etc
# rm -rf /usr/local/squid
# mkdir -p /usr/local/squid/var/cache        删除原先记录，新建缓存目录
# cd /usr/local/src/squid-2.5.STABLE2        必须有X的权限
# export CFLAGES=‘-O2 -mcpu=i586‘
[root@test squid-2.5.STABLE2]# ./configure --prefix=/usr/local/squid      \
> --enable-gnuregex --enable-async-io=80 --enable-icmp \
> --enable-kill-parent-hack --enable-snmp      \
> --disable-ident-lookups --enable-cahce-digests \
> --enable-err-language="Traditional_Chinese"      \
> --enable-poll --enable-linux-netfilter
[root@linux72r squid]# ./configure --prefix=/usr/local/squid      --enable-gnuregex --enable-async-io=80 --enable-icmp --enable-kill-parent-hack --enable-snmp      --disable-ident-lookups --enable-cahce-digests --enable-err-language="Traditional_Chinese"      --enable-poll --enable-linux-netfilter
# make && make install
# useradd squid0
# passwd squid0                     建立一个普通的帐号squid0，也可以用nobody或squid 但这两个帐号的密码不更变掉
# cd /usr/local/squid/etc
# vi squid.conf
# chown -R squid0:squid0 /usr/local/squid           第一步         必须修改成启用者的使用权限
# /usr/local/squid/sbin/squid -z                    第二步         这两步的顺序不能颠倒，不然squid就不能启动了
# su -l squid0
$ /usr/local/squid/sbin/squid -D                                    去掉DNS检测的启动，当你在LAN中linux没连接internet时 squid的启动方式
则           # su -l squid0 -c "/usr/local/squid/sbin/squid -D"
# su -l squid0 -c "/usr/local/squid/bin/RunCache &"                当linux连接了initernet时的启动方式，会自动检测DNS
# netstat -tln | grep 3128

[root@linux72 root]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=linux72
[root@linux72 root]# cat /etc/sysconfig/network-scripts/ifcfg-eth0         接内部的LAN
DEVICE=eth0

NETMASK=255.255.248.0
NETWORK=10.10.0.0
GATEWAY=10.10.1.1
ONBOOT=yes
[root@linux72 root]# cat /etc/sysconfig/network-scripts/ifcfg-eth1         用交叉线连接“SMC 本地连接”网卡

ONBOOT=yes
[root@linux72 root]# cat /etc/resolv.conf
nameserver 192.168.0.1                                       GATEWAY 和 DNS 都要设置成 192.168.0.1
nameserver 202.96.128.166
nameserver 10.10.7.32
nameserver 202.96.128.68
[root@linux72 root]# route -n

[root@linux72 root]# route add default gw 192.168.0.1 eth1                        这个指令很重要，不然 LINUX无法访问INTERNET，更不要说SQUID了
[root@linux72 root]# su -l squid -c "/usr/local/squid/sbin/squid -D"
[root@linux72 root]# /etc/init.d/network restart
[root@linux72 root]# /etc/rc.d/init.d/xinetd restart
[root@linux72 root]# cat /etc/rc.d/rc.local             让其开机自动运行squid
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don‘t
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
route add default gw 192.168.0.1 eth1
su -l squid -c "/usr/local/squid/sbin/squid -D"
[我的linux之路]关闭squid1. ps -ef | grep squid 2. kill squid_process_id(例如:kill 581) 3. tail cache.log 或 ps -ef | grep squid 查看squid是否已被 kill 掉了. 4. cd /export/home/squid/bin 5. ./squid -k shutdown (将squid 依正常程序 shutdown) 6. 用ps -ef 看是否有dnsserver, squid 等程式在跑，若无则可以关机。
