It is also the name of a foundation, an armed helicopter and so on Baidu Encyclopedia Apache

Centos7 Apache configuration example
Step 1 configure the scfan.conf configuration file:
# /etc/httpd/conf.d/scfan.conf
User scfan
Group scfan
<VirtualHost *:80>
DocumentRoot "/home/scfan/project/FISAMS/branches/branch_scfan/src/web/fdm"
<Directory "/home/scfan/project/FISAMS/branches/branch_scfan/src/web/fdm">
options Indexes MultiViews
AllowOverride all
Allow from all
</Directory>
</VirtualHost>
Step 2 rename welcome.conf:
# After renaming, testing 123 will no longer be displayed, but a detailed error will be displayed mv /etc/httpd/conf.d/welcome.conf /etc/httpd/conf.d/welcome.conf.bak
Step 3 restart the service:
/bin/systemctl restart httpd.service
Report errors: StackOverFlow - You don't have permission to access / on this server. , the following steps have solved this problem, which can be used for reference here
Step 4 directory authorization:
# Single level authorization is adopted to avoid the permission change of the whole directory file [root@fdm conf]# chmod +x /home/scfan/project/FISAMS/branches/branch_scfan/src/web/fdm [root@fdm conf]# chmod +x /home/scfan/project/FISAMS/branches/branch_scfan/src/web/ [root@fdm conf]# chmod +x /home/scfan/project/FISAMS/branches/branch_scfan/src/ [root@fdm conf]# chmod +x /home/scfan/project/FISAMS/branches/branch_scfan/ [root@fdm conf]# chmod +x /home/scfan/project/FISAMS/branches/ [root@fdm conf]# chmod +x /home/scfan/project/FISAMS/ [root@fdm conf]# chmod +x /home/scfan/project [root@fdm conf]# chmod +x /home/scfan [root@fdm conf]# chmod +x /home
Step 5 modify the configuration file / etc/httpd/conf/httpd.conf:
# Configure the scfan.conf configuration file corresponding to the listening port 41 #Listen 12.34.56.78:80 42 Listen 80 43 Listen 8888 44 LimitRequestLine 40940 # Limit the Apache request length and increase it according to actual needs # Note the following code 105 # <Directory /> 106 # AllowOverride none 107 # Require all denied 108 # </Directory>
Step 6 restart the service:
/bin/systemctl restart httpd.service
Apache test page
The Apache test page means:
The Apache test page means that your server is properly configured and ready to use. Technically, this page is the default index page when you first install the Apache Web server.
How to make the Apache test page disappear
Just open the / var/www/index.html file and modify or delete it (although it may trigger new errors). Under Red Hat Enterprise Linux/CentOS/Fedora Core, rename or delete the file / etc/httpd/conf.d/welcome.conf to make sure you don't see the Apache test page.
You can now add content to the directory / var/www/html /. Note that before you do so, users who visit your site will see the default page, not your content. To prevent the use of this page, follow the instructions in the file / etc/httpd/conf.d/welcome.conf.
Apache problem log
Apache has not been designed to serve pages while running as root
Problem Description:
Unable to start httpd service under root

resolvent:
For configuration of / etc/httpd/conf.d/fdm.conf, User and Group cannot be root, just modify to other users
User fdm Group fdm <VirtualHost *:80> DocumentRoot /home/fdm/web/fdm <Directory /home/fdm/web/fdm> options Indexes MultiViews AllowOverride all Allow from all </Directory> </VirtualHost>
Forbidden You don't have permission to access xxx.html
Problem Description:
Insufficient file permissions
Solution 1:
# Tier one authorization chmod +x /dira chmod +x /dira/dirb/ chmod +x /dira/dirb/index.html # Or directly chmod 777 -R /dira/dirb/index.html
Solution 2:
Modify the configuration file / etc/httpd/conf/httpd.conf
DocumentRoot "/home/fdm/web/fdm"
Solution 3:
Modify the configuration file / etc/httpd/conf/httpd.conf
# Note the following code 105 # <Directory /> 106 # AllowOverride none 107 # Require all denied 108 # </Directory>
In the above cases, different solutions to different problems can be used in superposition.
