Install and configure Apache in Linux

1. Download and install
   Download httpd-2.2.6.tar.gzfrom http://httpd.apache.org/and upload it to linuxlater.
   Decompress the tar-zxvf httpd-2.2.6.tar.gz, A httpd-2.2.6 directory appears in the current directory, and then run the following commands in sequence
   Music httpd-2.2.6 Apache
   CD Apache
   To set the installation parameters, run the following command:
   ./Configure -- prefix =/usr/local/apache2 -- enable-module = so
   The prefix parameter indicates that Apache is installed in the/usr/local/apache2 directory. If the login user is not root, the user may not have the permission to create a directory under/usr/local, in this case, an error is reported during make install. There are two solutions: 1) modify the prefix parameter to point to the path where a logon user has permission to create a directory; 2) use the root user to create the apache2 directory under the/usr/local directory, then, grant the WRX permission of apache2 to the login user.
   Finally, compile and install. Execute the following commands in sequence:
   Make
   Make install
   In short, the command sequence executed in the installation sequence is as follows. If no error occurs, the installation is successful.
   Tar-zxvf httpd-2.2.6.tar.gz
   Music httpd-2.2.6 Apache
   CD Apache
   ./Configure -- prefix =/usr/local/apache2 -- enable-module = so
   Make
   Make install
   Main Apache directories and files
   Location of the main configuration file:/etc/httpd/CONF/* Or/usr/local/apache2/CONF/httpd. conf
   Start script/etc/rc. d/init. d/httpd
   Help document/usr/local/apache2/manual/* html
   Icon files/usr/local/apache2/icons/* Used in HTML webpages /*
   Create and update Apache user programs/usr/local/apache2/htpasswd
   HTTP server program/usr/sbin/httpd
   Log File/usr/local/apache2/logs
2. STARTUP configuration
   Modify the PATH environment variable, open. bash_profile in the home directory of the logged-on user, and add a line to the file.
   Path = $ path:/usr/local/apache2/bin
   Log out and log on again. Run apachectl-L. If any information is returned, the path is set successfully.
   The Apache configuration file is/usr/local/apache2/CONF/httpd. conf.
   The default listening port of Apache is 80. On Linux/Unix, only the root user has the permission to open a port smaller than or equal to 1024. Therefore, to enable Apache as a non-root user, you must modify the default port to enable httpd. conf. Modify the listen attribute (or port) to 8000.
   Run the command apachectl start. If no error message is displayed (if any, correct the error according to the error message), open IE and enter http: // ip in the address bar: 8000 (the IP address here is the IP address of the Apache installation host). If a page is displayed, it indicates that Apache is successfully started.
3. Parameter description
   Servertype standlone/inetd server running mode
   Port 80 or the port number listened to by listen 80 in standlone Mode
   Owner of the user nobody process
   Group nobody
   Serveradmin admin @ localhost administrator mailbox
   Serverroot "/home/httpd/" Server File Location
   Servername httpserver server name
   Timeout 300 set the connection timeout between the server and the client
   Number of clients allowed to connect simultaneously in maxclient 300
   Proxyrequests on allows proxy
   DocumentRoot "/home/httpd/html" provides the root directory of the server documentation service
   Directory of the user's home page on the userdir public_html Server
   Directoryindex index.html Directory Index File
   Accessfilename. htaccess file name that contains access control information in each directory
   Alias/icons/"/home/user/icons/" creates an alias for a document not under DocumentRoot
   <Directory> </directory> directory settings. You can add some directory parameters in the middle, for example:
   <Directory "/">
   Options Indexes
   AllowOverride none
   Order allow, deny
   Allow from all
   </Directory>
   In the preceding directory settings, the options Option configuration command is used to control the access characteristics of the directory.
   Execcgi: Execute the CGI script.
   Indexes: returns a list of objects when accessing a directory without an index.
   Which settings in the AllowOverride command ". htaccess" file allow overwrite previous settings?
   None: Do not read. htaccess
   Limit: overwrite commands (allow, deny) that control host access)
   Authconfig: allowed to overwrite Authentication-related commands (authtype, authname)
   Here is none
   Order command
   Control the order in which commands allow and deny are processed
   For example:
   Order allow, deny
   Deny from all
   Allow from host11
   Allow command
   For a directory, the allow command sets which hosts are allowed to access
   ALL: All Hosts
   Or Domain Name: eloo.com
   Or a complete IP Address: 192.168.0.1
   Network number/subnet mask: 192.168.0.0/255.255.255.0
   Network number/NNN: 192.168.0.0/24 indicates a range of IP addresses
   Deny command
   For a directory, the allow command sets which hosts are not allowed to access
   -All: All Hosts
   Or Domain Name: eloo.com
   Or a complete IP Address: 192.168.0.1
   Network number/subnet mask: 192.168.0.0/255.255.255.0
   Network number/NNN: 192.168.0.0/24 indicates a range of IP addresses
4. End
   Different versions of Apache have minor differences in directory and parameter names, which can be guessed by name.
   Thank you for your attention.
