来看看:centos下复杂设置安装Squid 3.0反向代办署理
如果你想在以后的生涯中在软件行业工作的话,学习linux是一项基本技能,所以打从你打算学习linux那天起,放弃windows吧!因为它除了能给你带来片刻的娱乐,别无其他;安装篇:
本教程使用情况为洁净centos5.5,事后分好并加载/data分区,而且封闭selinux及iptables
起首修正文件形貌符并设定一时端口局限,这些设置重启后失效
.代码以下:
cat>>/etc/security/limits.conf<<DDD
*softnofile8192
*hardnofile20480
DDD
cat>>/etc/sysctl.conf<<DDD
#settempportrange
net.ipv4.ip_local_port_range=3276861000
DDD
init6
确认修正是不是准确
.代码以下:
#ulimit-n
8192
#sysctl-nnet.ipv4.ip_local_port_range
net.ipv4.ip_local_port_range=3276861000
增加squid公用账户
.代码以下:
groupaddsquid
useradd-gsquid-s/bin/false-Msquid
增加日记目次、设置缓存和日记目次的权限
.代码以下:
mkdir/data/squidlog/
chown-Rsquid.squid/data
然后上传大概wgetsquid3.0软件tar包,tarzxvf解压,而且进进解压后的目次安装编译
.代码以下:
./configureCprefix=/usr/local/squid3Cenable-async-io=100Cwith-pthreadsCenable-storeio="aufs,diskd,ufs"Cenable-removal-policies="heap,lru"Cenable-icmpCenable-delay-poolsCenable-useragent-logCenable-referer-logCenable-kill-parent-hackCenable-arp-aclCenable-default-err-language=Simplify_ChineseCenable-err-languages="Simplify_ChineseEnglish"Cdisable-pollCdisable-wccpCdisable-wccpv2Cdisable-ident-lookupsCdisable-internal-dnsCenable-basic-auth-helpers="NCSA"Cenable-stacktraceCwith-large-filesCdisable-mempoolsCwith-filedescriptors=65535Cenable-sslCenable-x-accelerator-var
make
makeinstall
makeinstall-pinger
至此squid已乐成安装了,然后人人本人所需的/usr/local/squid3/etc/squid.conf设置文件,我这边的设置文件将会在本文开端贴出来供人人研讨。
写好设置文件后实行上面的命令初始化cache目次
/usr/local/squid3/sbin/squid-z
然后运转squid,注:-D参数用来跳过DNS检测
/usr/local/squid3/sbin/squid-D
最初设置squid开机主动启动
echo"/usr/local/squid3/sbin/squid-D">>/etc/rc.local
保护篇:
以下是squid经常使用的命令
假如修正过设置文件,则用上面的命令重读设置文件(立即失效)
/usr/local/squid3/sbin/squid-kreconfigure
反省设置文件设置的语法是不是准确
注:只要像如许的“cache_cf.cc(346)squid.conf:14unrecognized:http1_port”才是语法毛病,
“WARNING:useofreload-into-ims……”这类提醒属于定见倡议,能够疏忽。
/usr/local/squid3/sbin/squid-kparse
检察squid的日记和历程,看squid运转是不是一般
.代码以下:
ps-ef|awk/^squid/
cat/data/squidlog/cache.log
/usr/local/squid3/sbin/squid-kcheck;echo$?
封闭squid
收回封闭旌旗灯号,等会话停止后完全封闭
/usr/local/squid3/sbin/squid-kshutdown
封闭squid(更高优先级,间接封闭squid)
/usr/local/squid3/sbin/squid-kinterrupt
封闭squid(最高优先级,间接杀逝世squid历程)
/usr/local/squid3/sbin/squid-kkill
转动日记文件
/usr/local/squid3/sbin/squid-krotate
设置每周二清晨四点30分主动转动日记
echo"304**2root/usr/local/squid3/sbin/squid-krotate">>/etc/crontab
今朝使用中的squid.conf文件,因为日记文件增加很快,以是间接输入到/dev/null抛弃失落了

买一本命令参考手册是必要的,遇到不知道怎么用的命令可以随时查询,这要比查man文档快.特别适合英语不好。 我是学习嵌入式方向的,这学期就选修了这门专业任选课。 掌握在Linux系统中安装软件,在安装Linux工具盘后大致日常所需的软件都会有,一般网络提供下载的软件都会有安装说明。 最好先搜寻一下论坛是否有您需要的文章。这样可以获得事半功倍的效果。 如果你想深入学习Linux,看不懂因为文档实在是太难了。写的最好的、最全面的文档都是英语写的,最先发布的技术信息也都是用英语写的。 就这样,我们一边上OS理论课,一边上这个实验,这样挺互补的,老师讲课,一步一步地布置任务 在学习linux的工程中,linux学习方法有很多种,这里是小编的学习心得,给大家拿出来分享一下。 随着实验课程的结束,理论课也该结束了,说实话教OS的这两位老师是我们遇到过的不错的老师(这话放这可能不太恰当). 选择交流平台,如QQ群,网站论坛等。
