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

★ Demand Realization

The domain name used to build Discuz is

Now we want to implement access to the domain name when jumping to

★ Configuration Steps

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


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

    • 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

  • 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
    /usr/local/apr/build-1/libtool--silent--mode=compile gcc-std=gnu99-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
    mod_rewrite.c:in function ' lookup_variable ':
    Mod_rewrite.c:1915:error: ' Conn_rec ' has no member named ' Remote_ip '
    Mod_rewrite.c:1954:error: ' Conn_rec ' has no member named ' REMOTE_ADDR '
    mod_rewrite.c:in function ' rewritelock_create ':
    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 Avoid-version Mod_rewrite.lo

    Seems to have succeeded,

  • chmod 755/usr/local/apache2/modules/ Change Permissions

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

  • 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:

    • 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/ Into server:/usr/local/apache2/modules/ 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.
