(5) Each request related to the special configuration;

(6) An enhanced version of the expression analysis;

(7) The duration of the millisecond-level persistent connection is defined;

(8) FQDN-based virtual host is no longer required namevirutalhost instructions;

(9) new directive, allowoverridelist;

(10) Support user-defined variables;

(11) Lower memory consumption;

New module:

(1) mod_proxy_fcgi

(2) mod_proxy_scgi

(3) Mod_remoteip

CentOS 6 Compile and install httpd-2.4:

Use of httpd-2.2 in CentOS 6 relies on apr-1.4+,apr-util-1.3.9

To compile the installation steps:

(1) Install the compiled development Environment Package Group: Development tools Server Platform Development Pcre-devel

(2) Turn off http-2.2 and turn off boot to prevent overwriting this version.

[[Email protected] ~]# service httpd stopstopping httpd: [OK][[email Protec Ted] ~]# Chkconfig httpd off

(3) Compile and install apr-1.5.0 and apr-util-1.5.3

[[email protected] apr-1.5.0]# ./configure --prefix= /usr/local/apr  #apr-util relies on Apr to compile and install Apr first, and specifies a different installation path from the system default. [[email protected] apr-1.5.0]# make && make install[[email  protected] apr-1.5.0]# ls /usr/local/apr        # Program files generated after compiling the installation bin  build-1  include  lib[[email protected]  apr-util-1.5.3]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr                            #编译apr-util, because it relies on APR packets, you need to specify the APR location. [[email protected] apr-util-1.5.3]# make -j 2 && make install[ [email protected] apr-util-1.5.3]# ls /usr/local/apr-utilbin  include   lib 

(4) Compile and install httpd-2.4

(5) Configure the environment variables for httpd-2.4 so that the system starts

[Email protected] ~]# export path=/usr/local/apache24/bin: $PATH #此种方法只对当前shell和子shell有效 [[email protected] ~]# echo $PA th/usr/local/apache24/bin:/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/ root/bin [[email protected] ~]# vim/etc/profile.d/httpd2-4.sh #为httpd-2.4 Increase the environment variable, which is valid for the newly logged-on user. Export path=/usr/local/apache24/bin/: $PATH [[email protected] conf]# apachectl start #配置完环境变量之后就能使用自带的脚本启动httpd2.4[[ Email protected] conf]# Hashhitscommand 1/usr/bin/vim 1/usr/local/apache24/bin/httpd 2/usr/local/apache24/bin/apache CTL #由此可以看出是httpd2.4 started instead of 2.2 3/bin/ls 3/USR/SBIN/SS

After the boot is complete, you can use the

(6) But every time we use our own script to start the service too much trouble, we can copy a http2.2 service script into httpd2.4.

[[email protected] init.d]# cp httpd httpd24[[email protected] init.d]#  vim httpd24         #复制服务脚本为2.4 and edit it #if [ -f / etc/sysconfig/httpd ]; then    #注释原来的配置文件 #         . /etc/sysconfig/httpd#fiapachectl=/usr/local/apache24/bin/httpd   # Refers to the APACHECTL program for httpd2.4httpd=${httpd-/usr/sbin/httpd}prog=httpdpidfile=${pidfile-/usr/local/apache24/logs/ httpd.pid}   #此处也制定为2.4 PID Path lockfile=${lockfile-/var/lock/subsys/httpd24}       #更改为2 .4retval=0stop_timeout=${stop_timeout-10}[[email protected] init.d]# service  httpd24 start     #测试结果可以使用了Starting  httpd: [[email protected]  init.d]# service httpd24 statushttpd  (pid  35131)  is running ...

CentOS 7:

Yum Install httpd

Configuration file:

/etc/httpd/conf/httpd.conf

/etc/httpd/conf.modules.d/*.conf

/etc/httpd/conf.d/*.conf

To configure the app:

(1) Switch the MPM used

Editing a configuration file/etc/httpd/conf.modules.d/00-mpm.conf

[[email protected] ~]# vim /etc/httpd/conf.modules.d/00-mpm.conf   #  select the mpm module which should be used by uncommenting  exactly# one of the following loadmodule lines:# prefork mpm:  implements a non-threaded, pre-forking web server# see: http:// Httpd.apache.org/docs/2.4/mod/prefork.htmlloadmodule mpm_prefork_module modules/mod_mpm_prefork.so       # worker MPM: Multi-Processing Module  implementing a hybrid# multi-threaded multi-process web server# see:  http://httpd.apache.org/docs/2.4/mod/worker.html# #LoadModule  mpm_worker_module modules/mod_mpm_ worker.so        #需要开启该MPM就把原来的注释掉 # event mpm: a variant  of the worker mpm with the goal of consuming# threads only for connections with  active processing# see: http://httpd.apache.org/docs/2.4/mod/event.html# #LoadModule  mpm_ Event_module modules/mod_mpm_event.so

(2) IP-based access control: (any page in 2.4 requires explicit authorization to be accessed)

[[email protected] conf]# vim httpd.conf<directory  "/var/www/html" >            #    # possible values  for the Options directive are  "None",  "All",     #  or any combination of:    #   indexes includes  FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews    #     # Note that  "MultiViews"  must be named *explicitly*  ---  "options all"     # doesn ' t give it to you.     #    # The Options directive is both  complicated and important.  please see    # http:// Httpd.apache.org/docs/2.4/mod/core.html#options    # for more information.    #     Options Indexes FollowSymLinks    #    #  Allowoverride controls what directives may be placed in .htaccess  files.    # It can be  "All",  "None", or any  Combination of the keywords:    #   options fileinfo  AuthConfig Limit    #    AllowOverride None     #    # controls who can get stuff from  this server.    #    Require all granted                         #需要在此为根文档目录改为所有人访问      #Require  all deny                          #不允许所有主机访问      #<RequireAll>                              #表示除了指定ip不能访问. #Require  all granted  #Require  not ip 172.16.100.2    #</ requireall>                 </Directory>

To control specific IP access:

Require IP ipaddr: IP access authorized for the specified source;

Require not IP ipaddr: Deny

To control specific host access:

Require host HOSTNAME: Authorized to access the specified source of hosts;

Require not host HOSTNAME: Deny

HOSTNAME:

FQDN: Specific Host

DOMIN.TLD: Specifies the name of the

(3) Virtual host

The FQDN-based virtual host no longer requires namevirutalhost instructions;
