CentOS 7.2配置Apache服务httpd（下）

一、Perl + mod_perl

安装mod_perl使Perl脚本速度快

[1] 安装mod_perl
# 从EPEL安装
[root@linuxprobe ~]# yum --enablerepo=epel -y install mod_perl
[2] 配置PerlRun模式，总是将Perl解释器放在RAM上。
[root@linuxprobe ~]# vi /etc/httpd/conf.d/perl.conf
# line 15: 取消注释 ( check codes and output warnings to logs )

PerlSwitches -w
# line 24: 取消注释

PerlSwitches -T
# line 30-36: 取消注释像下面一样

Alias /perl /var/www/perl
<Directory /var/www/perl> # the directory for mod_perl environment

  SetHandler perl-script # processes files as perl-scripts under this directory

#  AddHandler perl-script .cgi
# set specific extension if do do not want to processes all files as CGI

#  PerlResponseHandler ModPerl::Registry
  PerlResponseHandler ModPerl::PerlRun
# specify PerlRun mode

  PerlOptions +ParseHeaders
  Options +ExecCGI
</Directory>
# line 43-49: 取消注释并添加如下信息

<Location /perl-status>
  SetHandler perl-script
  PerlResponseHandler Apache2::Status
  Require ip 127.0.0.1 10.1.1.1/24
# add access permission

#  Order deny,allow
#  Deny from all
#  Allow from .example.com
</Location>
[root@linuxprobe ~]# systemctl restart httpd

[3] 创建测试脚本以确保设置不是ploblem。如果显示如下所示的结果，就可以。
[root@linuxprobe ~]# mkdir /var/www/perl
[root@linuxprobe ~]# vi /var/www/perl/test-mod_perl.cgi

#!/usr/bin/perl

use strict;
use warnings;

print "Content-type: text/html\n\n";
print "<html>\n<body>\n";
print "<div style=\"width:100%; font-size:40px; font-weight:bold; text-align:center;\">";

my $a = 0;
&number();

print "</div>\n</body>\n</html>";

sub number {
  $a++;
  print "number \$a = $a";
}

[root@linuxprobe ~]# chmod 705 /var/www/perl/test-mod_perl.cgi
#客户端浏览器访问：http://linuxprobe.org/perl/test-mod_perl.cgi

[4]  配置在RAM上具有代码缓存的注册表模式

[root@linuxprobe ~]# vi /etc/httpd/conf.d/perl.conf
Alias /perl /var/www/perl
<Directory /var/www/perl>
  SetHandler perl-script
  PerlResponseHandler ModPerl::Registry # uncomment

#
  PerlResponseHandler ModPerl::PerlRun # comment out

  PerlOptions +ParseHeaders
  Options +ExecCGI
</Directory>
[root@linuxprobe ~]# systemctl restart httpd

[5] 访问作为[4]节的示例的测试脚本，然后变量通过重新加载而增加，因为变量被高速缓存在RAM上。所以有必要编辑注册表模式的代码,这里浏览器没刷新一次，$a值加一。

[root@linuxprobe ~]# vi /var/www/perl/test-mod_perl.cgi

#!/usr/bin/perl

use strict;
use warnings;

print "Content-type: text/html\n\n";
print "<html>\n<body>\n";
print "<div style=\"width:100%; font-size:40px; font-weight:bold; text-align:center;\">";

my $a = 0;

&number($a
);

print "</div>\n</body>\n</html>";

sub number {

  my($a) = @_;

  $a++;
  print "number \$a = $a";
}

[6]顺便说一下，可以看到mod_perl的状态来访问“http：//（主机名或IP地址）/ perl-status”。

二、PHP + PHP-FPM

安装PHP-FPM使PHP脚本速度快

[1]安装PHP，请参考这里。
[2]安装PHP-FPM。
[root@linuxprobe ~]# yum -y install php-fpm
[3]   配置Apache httpd。
[root@linuxprobe ~]# vi /etc/httpd/conf.d/php.conf
# line 5: change like follows
<FilesMatch \.php$>
#
  SetHandler application/x-httpd-php
  SetHandler "proxy:fcgi://127.0.0.1:9000"

</FilesMatch>
[root@linuxprobe ~]# systemctl start php-fpm
[root@linuxprobe ~]# systemctl enable php-fpm
[root@linuxprobe ~]# systemctl restart httpd

[4]创建phpinfo并访问它，然后如果“FPM / FastCGI”显示，它是确定。
[root@linuxprobe ~]# echo '<?php phpinfo(); ?>' > /var/www/html/info.php

三、Python + mod_wsgi

安装mod_wsgi（WSGI：Web服务器网关接口），使Python脚本更快

[1] 安装mod_wsgi .
[root@linuxprobe ~]# yum -y install mod_wsgi
[2] 例如，将mod_wsgi配置为可以访问/ test_wsgi，后端是/var/www/html/test_wsgi.py.
[root@linuxprobe ~]# vi /etc/httpd/conf.d/wsgi.conf
# create new

WSGIScriptAlias /test_wsgi /var/www/html/test_wsgi.py
[root@linuxprobe ~]# systemctl restart httpd

[3] 创建您在上面设置的测试脚本.
[root@linuxprobe ~]# vi /var/www/html/test_wsgi.py
# create new

def application(environ,start_response):
  status = '200 OK'
  html = '<html>\n' \
      '<body>\n' \
      '<div style="width: 100%; font-size: 40px; font-weight: bold; text-align: center;">\n' \
      'mod_wsgi Test Page\n' \
      '</div>\n' \
      '</body>\n' \
      '</html>\n'
  response_header = [('Content-type','text/html')]
  start_response(status,response_header)
  return [html]

[4]配置如果你使用Django。 （[参考安装Django](http://blog.csdn.net/wh211212/article/details/52992413)）例如，在“wang”下拥有的“/home/wang/ venv/testproject”下配置“testapp”

[root@linuxprobe ~]# vi /etc/httpd/conf.d/django.conf
# create new

WSGIDaemonProcess testapp python-path=/home/wang/venv/testproject:/home/wang/venv/lib/python2.7/site-packages
WSGIProcessGroup testapp
WSGIScriptAlias /django /home/wang/venv/testproject/testproject/wsgi.py

<Directory /home/wang/venv/testproject>
  Require all granted
</Directory>

[root@linuxprobe ~]# systemctl restart httpd

四、访问日志分析器：AWstats

安装AWstats，它报告http日志以分析对http服务器的访问。

[1] 安装AWstats。

# install from EPEL
[root@linuxprobe ~]# yum --enablerepo=epel -y install awstats
# awstats.（hostname）.conf是自动生成的
[root@linuxprobe ~]# vi /etc/awstats/awstats.linuxprobe.org.conf
# line 122: change
# if your config for log format in httpd.conf is 'combined' Set here '1'
# If log-config is 'common' set here '4', but in this case, some informations can't be get (browser info and so on)
LogFormat=1
# line 153: specify your hostname
SiteDomain="linuxprobe.org
# line 168: set IP address you'd like to exclude
HostAliases="localhost 127.0.0.1 REGEX[server\.world$] REGEX[^10\.1\.1\.]
"
[root@linuxprobe ~]# vi /etc/httpd/conf.d/awstats.conf
# line 30: IP address you permit to access
Require ip 10.1.1.0/24

[root@linuxprobe ~]# systemctl restart httpd
# generate reports ( reports are updated for hourly by Cron )

[root@linuxprobe ~]# /usr/share/awstats/linuxproberoot/cgi-bin/awstats.pl -config=linuxprobe.org -update

Create/Update database for config "/etc/awstats/awstats.linuxprobe.org.conf" by AWStats version 7.4 (build 20150714)

[2]访问“http：//（您的服务器的名称或IP地址/）/awstats/awstats.pl”，然后显示以下屏幕，可以看到httpd日志报告。
