基于Squid的反向加速多个WEB服务器
Step I - Downloading and compiling Squid
Wget http://www.squid-cache.org/Versions/v2/2.5/squid-2.5.STABLE13.tar.gz
[root@redhatas4 squid-2.5.STABLE13]# tar zxvf squid-2.5.STABLE13.tar.gz
[root@redhatas4 squid-2.5.STABLE13]# cd squid-2.5.STABLE13
[root@redhatas4 squid-2.5.STABLE13]# vi config.sh
写入内容如下：
| 代码: |
| #!/bin/bash SQUID_ROOT="/Data/apps/squid"
./configure --prefix=$SQUID_ROOT \ --enable-useragent-log \ --enable-referer-log \ --enable-default-err-language=Simplify_Chinese \ --enable-err-languages="Simplify_Chinese English" \ --disable-internal-dns |
[root@redhatas4 squid-2.5.STABLE13]# sh config.sh
[root@redhatas4 squid-2.5.STABLE13]# make
[root@redhatas4 squid-2.5.STABLE13]# make install
Step II - Basic Configuration
[root@redhatas4 squid]# cd /Data/apps/squid/
[root@redhatas4 squid]# mkdir cache
[root@redhatas4 squid]# chown squid.squid *
A、 在/etc/hosts中：加入内部的DNS解析，比如：
61.135.132.176 www.sohu.com
202.108.33.32 www.sina.com
202.108.9.16 www.163.com
202.108.12.68 www.tom.com
B、vi /Data/apps/squid/etc/squid.conf
Step III - Starting Squid
A、创建缓存目录
[root@redhatas4 sbin]# ./squid –z
B、测试Squid运行状况
[root@redhatas4 sbin]# ./ squid –NCd1
成功后将出现"Ready to serve requests".否则请检查配置文件
C、建立Squid启动脚本
# cd /etc/rc.local
#vi squid.sh
| 代码: |
| #!/bin/sh
# if ! PREFIX=$(expr $0 : "\(/.*\)/etc/rc\.d/$(basename $0)\$"); then # echo "$0: Cannot determine the PREFIX" >&2 # exit 1 # fi case "$1" in start) if [ -x /Data/apps/squid/sbin/squid -a -f /Data/apps/squid/etc/squid.conf ]; then (cd /Data/apps/squid/var/logs; /Data/apps/squid/sbin/squid >/dev/null 2>&1 &) ; echo -n ' squid' fi ;; stop) /Data/apps/squid/sbin/squid -k shutdown 2>&1 # Uncomment this if you'd like the system to (attempt to # wait for) squid to shut down cleanly #echo "Sleeping for 45 seconds to allow squid to shutdown.." #sleep 45 ;; *) echo "Usage: `basename $0` {start|stop}" >&2 ;; esac exit 0 |
启动squid
/etc/rc.local/squid.sh start 启动squid
/etc/rc.d/squid.sh stop 停止squid
启用新配置：
/Data/apps/squid/sbin/squid -k reconfig
通过crontab每天0点截断/轮循日志：
0 0 * * * (/Data/apps/squid/sbin/squid -k rotate)
