Now talk about some of the parameters and commands that Apache uses every day.

Basic:
#service httpd Restart/restart Apache service

/etc/httpd/conf/httpd.conf/apache configuration file

/var/www/html/Here is the CentOS default "home" directory;
/var/www/error/default system error message, host settings error or browser-side required data error, the error message in the browser is based on the information here
/var/www/icons/provides some small icons of Apache;
/var/www/cgi-bin/default Some executable CGI programs placed in the directory;
/VAR/LOG/HTTPD/log file directory, the file here is very easy to change a lot, need to provide enough space;

Four, set up boot

#chkconfig--levels 3 httpd on/Set APACHEP service set to boot
#chkconfig--list httpd/view boot Service list
httpd 0:off 1:off 2:off 3:on 4:off 5:off/If, execute the previous command, the result is this. The instructions are set to succeed.

Five or one server multiple site Settings

is a single-server multiple-site setup method

If your IP is 192.168.1.1

1, create a directory

#mkdir/etc/httpd/conf/vhost/

2. Modify/etc/httpd/conf/httpd.conf

Plus

Namevirtualhost 192.168.1.1:80 (if it is single IP to fill out as Namevirtualhost *:80)

Include/etc/httpd/conf/vhost/*.conf

3. Recommend the virtual host file under/etc/httpd/conf/vhost/

Vi/etc/httpd/conf/vhost/web001.conf

Edit the following content to copy in

<virtualhost *:80>

<directory "/WEBSERVER/WEB001/" >

Options-indexes FollowSymLinks

Allow from all

AllowOverride All

</Directory>

ServerAdmin paipat@vip.qq.com

DocumentRoot "/webserver/web001/"

ServerName paipat.com

Serveralias www.paipat.com

ErrorLog Logs/www.paipat.com-error_log

</VirtualHost>

Create a few more files, only need to modify the directory and domain name OK.
---------------------------------------------
If it is a level two domain name, press the following setting

<virtualhost *:80>

<directory "/WEBSERVER/WEB001/" >

Options-indexes FollowSymLinks

Allow from all

AllowOverride All

</Directory>

ServerAdmin paipat@vip.qq.com

DocumentRoot "/webserver/web001/"

ServerName bbs.paipat.com

ErrorLog Logs/www.paipat.com-error_log

</VirtualHost>

Remember to add 755 or 777 permissions to the site directory, #chmod 777/www.111cn.net/web001/
