Post: how to plan a high-capacity Apache server?

To plan a high-capacity web server, we will do it in the following steps:

I. Network Environment

----
| (Eth0: 192.168.11.8) | (eth0: A. B. C. d)
| A | -------------------- | B | -------------> ISP
-- (Eth1: 192.168.11.5 )--
Web.company.com firewall.company.com

A is a web server inside the lan. Install RedHat Linux 6.xand compile Apache + PhP4 + MySql
B is the company firewall, and the external address is a. B .c.d, which is the only path to the Internet. Run Apache on B
Reverse proxy to internal machine B. Assume that the company's domain name is @ company.com, and B is the Domain Name Server of this domain.

Ii. Organizational Structure of web directories
We plan to place the Web server data file under a separate directory/WWW, and then create the corresponding
Subdirectory. If we plan to set the Web server web.company.com, create a directory.
/Www/web.company.com with the following structure:

/Www/web.company.com/public/htdocs
/Cgi-bin
/Www/web.company.com/staging/htdocs
/Cgi-bin
/Www/web.company.com/#/htdocs
/Cgi-bin
　　　　　　　　　　　　　　　　　　
Iii. Access methods and Virtual Hosts
Use port-based virtual hosts to access the staging and developer directories, corresponding to ports and 82 respectively.
The following is the section of the virtual host in the Apache configuration file/usr/local/Apache/CONF/httpd. conf.
Configuration:
Listen 80
Listen 192.168.11.8: 81
Listen 192.168.11.8: 82

<Virtualhost 192.168.11.8: 81>
DocumentRoot/www/web.company.com/staging/htdocs/
ScriptAlias/cgi-bin/www/web.company.com/staging/cgi-bin/
Transferlog "|/usr/local/Apache/bin/cronolog/usr/local/Apache/logs/web/staging/% Y/% m/% d/access_log"
Errorlog "|/usr/local/Apache/bin/cronolog/usr/local/Apache/logs/web/staging/% Y/% m/% d/error_log"
</Virtualhost>

<Virtualhost 192.168.11.8: 82>
DocumentRoot/www/web.company.com/#/htdocs/
ScriptAlias/cgi-bin/www/web.company.com/#/cgi-bin/
Transferlog "|/usr/local/Apache/bin/cronolog/usr/local/Apache/logs/web/developer/% Y/% m/% d/access_log"
Errorlog "|/usr/local/Apache/bin/cronolog/usr/local/Apache/logs/web/developer/% Y/% m/% d/error_log"
</Virtualhost>

Note: The above is port-based virtual host settings, to access the test server, with http://web.company.com: 81/
Development Server http://web.company.com: 82/
The preceding transferlog and errorlog are not in the default format, but are recommended on the Apache website every day.
The year/month/day format of a file, which can be downloaded and compiled from http://www.ford-mason.co.uk/resources/cronolog/
And then install it in/usr/local/Apache/bin/cronolog to view more information on the Apache website.

If there are other home pages that need to be served on this server, for example, create a subdirectory hr.company.com (Personnel Department) under/www)
Creates an IP alias for host a, such as 192.168.11.9, and then configures the same port-based virtual host.

Iii. Personal Homepage information
If Apache runs as a user group and the user's home directory is/home/jephe, create a directory in this directory
Public_html
A. Set the user's main directory/home/jephe to give the nobody group the read and execute permissions
Chmod 750-r/home/jephe
B. Set the public_html directory permission in the user's home directory/home/jephe.
Chmod-r 2770/home/jephe/public_html

C. Set the owner of the user's home directory
Chown-r jephe. Nobody/home/jephe/public_html
You can upload the home page file to your directory through FTP. You need to set the default umask value uploaded by FTP in/etc/inetd. conf.
U002,
Ftp stream tcp Nowait root/usr/sbin/tcpd in. ftpd-l-a-u002
Then use killall-hup inetd to take effect.
Last with http://web.company.com /~ Jephe/visit the personal homepage.

Iv. Apache reverse proxy on firewall machine B

The settings are as follows:

Namevirtualhost A. B. C. d

<Virtualhost A. B. C. D>
Servername web.company.com
Errorlog "|/usr/local/Apache/bin/cronolog/var/log/httpd/web/% Y/% m/% d/error_log"
Transferlog "|/usr/local/Apache/bin/cronolog/var/log/httpd/web/% Y/% m/% d/access_log"
Rewriteengine on
Rewriterule ^ (/. *) $ http: // 192.168.11.8/$1 [P, L]
Proxyrequests off
</Virtualhost>

V. Backup
Use rsync to back up the home directory/www/web.company.com/public/htdocs. For more information, see
