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。
