Apache Virtual host, log polling, log statistics, go to version optimization

One, the virtual host

1. Domain-based virtual host

Www.zhang.com/var/html/www

Blog.zhang.com/var/html/blog

Bbs.zhang.com/var/html/bbs

#创建虚拟机目录

Mkdir/var/html/{www,blog,bbs}-P

tree/var/html/

/var/html/

├──bbs

├──blog

└──www

#创建默认文件

Touch/var/html/{www,blog,bbs}/index.html

tree/var/html/

/var/html/

├──bbs

│└──index.html

├──blog

│└──index.html

└──www

└──index.html

#写入默认文件内容

For name in www blog bbs;do echo "http:/$name. zhang.com" >/var/html/$name/index.html;done

For name in www blog bbs;do cat/var/html/$name/index.html;done

Http://www.zhang.com

Http://blog.zhang.com

Http://bbs.zhang.com

#配置虚拟站点

Vim/usr/local/httpd/conf/extra/httpd-vhosts.conf

<virtualhost *:80> ServerAdmin [email protected] documentroot "/var/html/www" ServerName www.zhang.com S Erveralias zhang.com errorlog "Logs/www-error_log" Customlog "Logs/www-access_log" common</virtualhost>

<virtualhost *:80> ServerAdmin [email protected] documentroot "/var/html/blog" ServerName blog.zhang.com Serveralias blog.com errorlog "Logs/blog-error_log" Customlog "Logs/blog-access_log" common</VirtualHost>< VirtualHost *:80> ServerAdmin [email protected] documentroot "/var/html/bbs" ServerName bbs.zhang.com Serve Ralias bbs.com errorlog "Logs/bbs-error_log" Customlog "Logs/bbs-access_log" common</virtualhost>

#修改主配置文件加载虚拟站点, remove the comment # number

Vim/usr/local/httpd/conf/httpd.conf

Include Conf/extra/httpd-mpm.confinclude conf/extra/httpd-vhosts.conf

#增加虚拟目录访问权限

Vim/usr/local/httpd/conf/httpd.conf

<directory "/var/html" > Options followsymlinks allowoverride None Require all granted</directory>

#检查配置文件, reload the configuration file

/etc/init.d/httpd-t

Syntax OK

/ETC/INIT.D/HTTPD Graceful

#测试访问站点, note that you need to configure the hosts on the client to configure domain name resolution

Http://www.zhang.com

Http://blog.zhang.com

Http://bbs.zhang.com

2. Port-based virtual host

#在主配置文件中增加端口监听

Vim/usr/local/httpd/conf/httpd.conf

Listen 80Listen 8000Listen 9000

#修改虚拟主机端口号

Vim/usr/local/httpd/conf/extra/httpd-vhosts.conf

<VirtualHost *:80>    ServerAdmin [email protected]     DocumentRoot  "/var/html/www"     ServerName www.zhang.com     ServerAlias zhang.com    ErrorLog  "Logs/www-error_log"      CustomLog  "Logs/www-access_log"  common</VirtualHost><VirtualHost *:8000>     ServerAdmin [email protected]    DocumentRoot  "/var /html/blog "    ServerName blog.zhang.com    ServerAlias  blog.com    errorlog  "Logs/blog-error_log"     CustomLog  " Logs/blog-access_log " common</VirtualHost><VirtualHost *:9000>     serveradmin [email protected]    documentroot  "/var/html/bbs"      ServerName bbs.zhang.com    serveralias bbs.com    errorlog  "logs/ Bbs-error_log "    CustomLog " Logs/bbs-access_log " common</VirtualHost>

#检查配置文件, reload the configuration file

/etc/init.d/httpd-t

Syntax OK

/ETC/INIT.D/HTTPD Graceful

3. IP-based virtual host

Vim/usr/local/httpd/conf/extra/httpd-vhosts.conf

<VirtualHost 10.0.1:80>    ServerAdmin [email protected]     DocumentRoot  "/var/html/www"     ServerName www.zhang.com     ServerAlias zhang.com    ErrorLog  "Logs/www-error_log"      CustomLog  "Logs/www-access_log"  common</VirtualHost><VirtualHost  10.0.2:8000>    serveradmin [email protected]     documentroot  "/var/html/blog"     ServerName blog.zhang.com     ServerAlias blog.com    ErrorLog  "Logs/blog-error_log"      CustomLog  "Logs/blog-access_log"  common</virtualhost><virtualhost 10.0.3:9000 >    ServerAdmin [email protected]    DocumentRoot  " /var/html/bbs "    sErvername bbs.zhang.com    serveralias bbs.com    errorlog   "Logs/bbs-error_log"     CustomLog  "Logs/bbs-access_log"  common</ Virtualhost>

Second, Apache log polling

1. Using Cronolog software to implement log polling

Tar zxvf cronolog-1.6.2.tar.gz

CD cronolog-1.6.2

./configure

Make

Make install

#查看cronolog软件安装路径

Ll/usr/local/sbin/cronolog

-rwxr-xr-x 1 root root 40438 April 22:49/usr/local/sbin/cronolog

#修改虚拟主机日志记录按天使用轮询

Vim/usr/local/httpd/conf/extra/httpd-vhosts.conf

<virtualhost *:9000> ServerAdmin [email protected] documentroot "/var/html/bbs" ServerName bbs.zhang.com Serveralias bbs.com errorlog "Logs/bbs-error_log" Customlog "|/usr/local/sbin/cronolog/usr/local/http/logs/access_ Bbs_%y%m%d.log "combined# Add the above row, the BBS for access to log polling, in days units </VirtualHost>

2. Using Apache to bring your own tools

Vim/usr/local/httpd/conf/extra/httpd-vhosts.conf

<virtualhost *:9000> ServerAdmin [email protected] documentroot "/var/html/bbs" ServerName bbs.zhang.com   Serveralias bbs.com errorlog "|/usr/local/httpd/bin/rotatelogs/usr/local/http/logs/access_bbs_%y%m%d-%h:%m.log 5M" #以大小为单位轮询日志 customlog "|/usr/local/httpd/bin/rotatelogs/usr/local/http/logs/access_bbs_%y%m%d-%h:%m.log 86400" combined# to BBS for access log polling, 86400 for the wonderful number, in days </VirtualHost>

3. Polling log files with shell scripts and timed tasks

cat/usr/local/httpd/logpolling.sh

Cd/usr/local/httpd/logs

MV Www-access_log www-access_$ (date +%f) _log

/usr/local/httpd/bin/apachectl Graceful

echo "0 0 * * */usr/local/httpd/logpolling.sh &>/dev/null" >>/var/spool/cron/root

Third, analysis of the log

#查看访问日志中访问次数最多的ip取最多的10个

awk ' {print '} ' Access_bbs_20170423.log |sort|uniq-c|sort-rn-k1|head-10# ibid ' {++s[$1]} END {for (key in S) print s[ Key],key} ' Access_bbs_20170423.log |sort-rn-k1|head-10

Iv. Modifying hidden version information

1. Change before compiling the installation

Vim/root/tools/httpd-2.4.25/include/ap_release.h

#define Ap_server_basevendor "Apache software Foundation" #define Ap_server_baseproject "Apache HTTP SERVER" #define AP_ Server_baseproduct "Apache" #define Ap_server_majorversion_number 2 #主版本 # define Ap_server_minorversion_number 4 #次版本号 # Define Ap_server_patchlevel_number #define Ap_server_devbuild_boolean 0

Vim/root/tools/httpd-2.4.25/os/unix/os.h

#define PLATFORM "Unix" #运行系统

2, after installation, modify the configuration file, hide version information

Curl-i 10.0.0.4 #查看版本信息

http/1.1 okdate:sun, Apr 15:35:39 gmtserver:apache/2.4.25 (Unix) php/5.6.30last-modified:thu, Apr 2017 1 7:33:10 gmtetag: "15-54d9c88ebe6ed" accept-ranges:bytescontent-length:21content-type:text/html

#去掉版本号

Vim/usr/local/httpd/conf/extra/httpd-default.conf

Servertokens prodserversignature Off

vim/usr/local/httpd/conf/httpd.conf, #去掉前面的注释 #

Include conf/extra/httpd-default.conf

#重新加载配置

.. /bin/apachectl Graceful

#重新查看版本信息

Curl-i 10.0.0.4

http/1.1 okdate:sun, Apr 15:39:10 gmtserver:apache #此次已不再显示版本信息Last-modified:thu, Apr 17:33:10 G Mtetag: "15-54d9c88ebe6ed" accept-ranges:bytescontent-length:21content-type:text/html
