LAMP (3)--apache Configure the domain name jump

★ Demand Realization

The domain name used to build Discuz is www.caoyue111.com

Now we want to implement access to the domain name www.hera111.com when jumping to www.caoyue111.com

★ Configuration Steps

• We only need to add the following content to the corresponding virtual host

Vim/usr/local/apache2/conf/extra/httpd-vhosts.conf

<ifmodule mod_rewrite.c> <== Open rewrite.c module (available apachectl-m to see if there is no module)
Rewriteengine on <== Open
Rewritecond%{http_host} ^www.hera111.com$ <== conditions
Rewriterule ^ (. *) $ http://www.caoyue111.com/$1 [r=301,l] <== results
</IfModule>

• Use the-t option to check if the configuration is error-free

• Restart Apache Service

★ I test in the browser found that the contents of the configuration did not take effect, through the inspection found that my system installed in Apache does not have a mod_rewrite module, the following describes the method of installing the Mod_rewrite module for Apache separately

• First into the Apache source directory

  The Apache source directory i downloaded earlier is stored under/usr/local/src/.

  
  

• Use the Find command to find the Mod_rewrite module in the current directory
  

  [[email protected] httpd-2.2.16]# find. -name mod_rewrite.c
  ./modules/mappers/mod_rewrite.c

• Enter the directory containing the Mod_rewrite

  [[Email protected] httpd-2.2.16]# CD./modules/mappers/

• /usr/local/apache2/bin/apxs-c mod_rewrite.c <== This command must be done in the directory that contains this module
  

  [Email protected] mappers]#/usr/local/apache2/bin/apxs-c mod_rewrite.c

  Mod_rewrite.c:2530:warning:implicit declaration of function ' Unixd_set_global_mutex_perms '
  Apxs:Error:Command failed with rc=65536

  Learned that this kind of error message may be related to Libtool version, and then I found that in the directory/usr/local/apache2/build there is no Libtool file, and then I recompile the Apache

• After recompiling Apache added a lot of static compiled files, but I see/usr/local/apache2/build this time still no Libtool file, continue to do

• cd/usr/local/src/httpd-2.2.16/modules/mappers/

  /usr/local/apache2/bin/apxs-c mod_rewrite.c

  [Email protected] mappers]#/usr/local/apache2/bin/apxs-c mod_rewrite.c
  /usr/local/apr/build-1/libtool--silent--mode=compile Gcc-prefer-pic-dlinux-d_reentrant-d_gnu_source-d_ Largefile64_source-g-o2-pthread-i/usr/local/apache2/include-i/usr/local/apr/include/apr-1-I/usr/local/apr/ Include/apr-1-c-o mod_rewrite.lo mod_rewrite.c && Touch Mod_rewrite.slo
  /usr/local/apr/build-1/libtool--silent--mode=link Gcc-o mod_rewrite.la-rpath/usr/local/apache2/modules-module- Avoid-version Mod_rewrite.lo

  Seems to have succeeded,

• chmod 755/usr/local/apache2/modules/mod_rewrite.so Change Permissions

• See files under/usr/local/apache2/modules It's true that mod_rewrite.so

• This time I restarted Apache and there was an error message

  Httpd:syntax error on line Of/usr/local/apache2/conf/httpd.conf:module Authn_file_module was built-in and can ' t be lo aded

  The reason for the error is: Although Apache needs to load the Authn_file_module module but now the module is built-in, no need to load module, so the Apaache configuration file does not need to load this module of the line, so the line is commented out.

  View all of Apache's built-in modules,/usr/local/apache2/bin/httpd-l

[[email protected] logs]#/usr/local/apache2/bin/httpd-l
Compiled in modules:
  core.c
 

• When the prompt is commented out, the error is also indicated

  [[email protected] logs]#/usr/local/apache2/bin/apachectl start
  Httpd:syntax error on line 147 Of/usr/local/apache2/conf/httpd.conf:cannot load/usr/local/apache2/modules/libphp5.so Into server:/usr/local/apache2/modules/libphp5.so:undefined symbol:ap_log_rerror_

  Baidu on the understanding of the solution is related to SELinux, but my current selinux is disabled and try to use this method is not resolved.

  This time I commented out the 147th line and found that the command under Apache2/bin was available.
