Apache configuration and application

1. Construction of Web virtual directories and user authorization restrictions

①Create user authentication data file

cd /usr/local/httpd/bin
htpasswd -c /usr/local/httpd/user zhangsan
htpasswd  /usr/local/httpd/user lisi
cat /usr/local/httpd/user

②Add user authorization configuration

vim /usr/local/httpd/conf/httpd.conf
（在最后写入以下内容）
Alias /test /var/www/html/test

<Directory "/var/www/html/test">
    AuthName "Hello!"
    AuthType Basic
    AuthUserFile /usr/local/httpd/user
    Require valid-user
   #authgroupfile /usr/local/httpd/conf/group
   #Require user zhangsan
   #Require group zhangsan
</Directory>

Alias /test /var/www/html/test     #设置虚拟目录的根目录，/test为虚拟目录名称

<Directory "/var/www/html/test">   #设置虚拟目录配置区域
    AuthName "Hello!"              #定义受保护的领域名称，会在认证对话框中显示
    AuthType Basic                 #设置认证的类型，Basic表示基本认证
    AuthUserFile /usr/local/httpd/user         #设置用于保存用户账号和密码的认证文件的路径
    Require valid-user             #开启用户认证，只有认证文件中的合法用户才能访问
   #authgroupfile /usr/local/httpd/conf/group  #设置用于保存组账号和密码的认证文件的路径
   #Require user zhangsan          #仅允许指定用户访问
   #Require group zhangsan         #仅允许指定组访问
</Directory>

③Verify user access authorization

mkdir -p /var/www/html/test
echo "<h1>this is test</h1>" > /var/www/html/test/index.html

systemctl restart httpd.service 

④Browser access verification

http://192.168.153.30/test

Two, Apache log split

Use Apache's own rotatelogs segmentation tool to automatically segment Apache logs according to the date of the day.

Apache日志文件所在文件位置：
/usr/local/httpd/logs

①Modify the httpd service configuration file and restart the service

vim /usr/local/httpd/conf/httpd.conf
-----修改273行附近该字段--------
ErrorLog "|/usr/local/bin/rotatelogs -l /var/log/httpd/error_%Y%m%d.log 86400"   #分割错误日志
-----修改308行附近该字段---------
CustomLog "|/usr/local/bin/rotatelogs -l /var/log/httpd/access_%Y%m%d.log 86400"    combined     #分割访问日志

ErrorLog "| rotatelogs 命令的绝对路径 -l 日志文件路径/网站名-error_%Y%m%d.log 86400"	'//which rotatelogs命令查看绝对路径，%Y%m%d表示年月日，86400表示一天的秒数'
CustomLog "| rotatelogs 命令的绝对路径 -l 日志文件路径/网站名-access_%Y%m%d.log 86400" combined 
#开头的 | 为管道符号。
#-l 选项表示使用本地时间为时间基准
#86400表示一天，即每天生成一个新的日志文件

Error log:

Modified to:

Access log:

Uncommented, modified to:

②Create a directory for saving the divided log file

mkdir /var/log/httpd               
systemctl restart httpd.service    

③View the split log

vim /var/log/httpd/error_20210106.log    

④ Configure virtual host log split

vim /usr/local/httpd/conf/extra/httpd-vhosts.conf 
<VirtualHost 192.168.153.30:80>
    DocumentRoot "/var/www/html/benet"
    ServerName www.benet.com
    ErrorLog "| /usr/local/bin/rotatelogs -l /var/log/httpd/benet.com-error_%F.log 86400"
   CustomLog "|/usr/local/bin/rotatelogs -l /var/log/httpd/benet.com-access_%F.log 86400"    combined
</VirtualHost>

<VirtualHost 192.168.153.30:8080>
    DocumentRoot "/var/www/html/accp"
    ServerName www.accp.com
    ErrorLog "|/usr/local/bin/rotatelogs -l /var/log/httpd/accp.com-error_%F.log 86400"
    CustomLog "|/usr/local/bin/rotatelogs -l /var/log/httpd/accp.com-access_%F.log 86400"    combined
</VirtualHost>

<Directory "/var/www/html">
    Options None
    AllowOverride None
    Require all granted
</Directory>

systemctl restart httpd.service

At this point, you can view the log in the /var/log/httpd directory

Three, AWStats analysis system

①Transfer the software package required to install AWStats to the /opt directory and decompress it

cd /opt
tar zxvf awstats-7.6.tar.gz
mv /opt/awstats-7.6 /usr/local/awstats

②Establish configuration files for the sites to be counted

cd /usr/local/awstats/tools
./awstats_configure.pl
......

Config file path ('none' to skip web server setup):
> /usr/local/httpd/conf/httpd.conf                 #输入httpd服务主配置文件的路径
Your web site,virtual server or profile name:
> www.wt.com                                       #输入要统计的站点域名
其它全部是y或者回车

③Modify the automatically generated awstats access permissions and load the CGI module (Apache2.4 or higher version needs to load the CGI module)

vim /usr/local/httpd/conf/httpd.conf

<IfModule !mpm_prefork_module>
       LoadModule cgid_ module modules/mod_cgid.so          #143行，取消注释
</IfModule>
<IfModule mpm_prefork_module>
       LoadModule cgi_module modules/mod_cgi.so             #取消注释
</IfModule>

ErrorLog "logs/error_log"                          #273行附近
CustomLog "logs/access_log" combined               #302行附近

<Directory "/usr/local/awstats/wwwroot">
Options None
AllowOverride None
#Order allow,deny               #G到最后一行，进行注释
#Allow from all                 #进行注释
Require all granted             #添加
</Directory>

④ Modify the site statistics configuration file

vim /etc/awstats/awstats.www.abc.com.conf

LogFile="/usr/local/httpd/logs/access_log"   #修改访问日志文件位置
DirData="/var/lib/awstats"                   #awstats目录默认不存在，需要手动创建

mkdir /var/lib/awstats

⑤Perform log analysis and set up cron scheduled tasks

systemctl restart httpd
cd /usr/local/awstats/tools/

./awstats_updateall.pl now          #更新数据(根据站点配置文件指定的日志文件路径)

⑥ Write planned tasks, update log file data every 5 minutes

crontab -e                          
*/5 * * * * /usr/local/awstats/tools/awstats_updateall.pl now

systemctl start crond

⑦Visit AwStats analysis system site

systemctl stop firewalld
systemctl disable firewalld
setenforce 0
echo "192.168.153.30 www.wt.com" >> /etc/hosts

浏览器访问:
http://www.wt.com/awstats/awstats.pl?config=www.wt.com

⑧ Optimize web page address

vim /var/www/html/aws.html
<html>
<head>
<meta http-equiv-refresh content="0;url=http://www.wt.com/awstats/awstats.pl?	config=www.wt.com">
</head>
<body></body>
</html>

HTML文件结构解释:
<html> </html>:用于HTML文件结构最外层表示的标签
<head></head>:用于HTML网页内容描述信息的头标签
<body></body>:用于显示网页内容的内容标签
<meta>:定义了HTML文档中的元数据，比如针对搜索引擎和更新频度的描述和关键词。这里的http-equiv=refresh用于实现网页自动跳转

浏览器访问:
