Configuring HTTP Support for PHP and web hosting

Configuring HTTPD support PHP

• HTTPD Master configuration file/usr/local/apache2.4/conf/httpd.conf
• Vim/usr/local/apache2.4/conf/httpd.conf
  修改以下4个地方ServerName  这个打开后开启httpd后没有警告Require all denied   这个修改为Require all granted 防止打开虚拟主机配置文件时403AddType application/x-httpd-php .php 加上这行才可以解析phpDirectoryIndex index.html index.php  添加默认索引页DocumentRoot "/usr/local/apache2.4/htdocs" 这个参数可以定义网站的域名根目录
• /USR/LOCAL/APACHE2.4/BIN/APACHECTL-T//Test syntax, the configuration needs to be checked before loading
• /usr/local/apache2.4/bin/apachectl Graceful//reload config file, do not restart service
• Iptables-i input-p TCP--dport 80-j ACCEPT//Open 80 port
• NETSTAT-LNTP//View 80 ports

• Opening the host IP address on the physical machine browser can be accessed
• Do not open IP home page troubleshooting ideas
  -Now on the physical machine to see if the IP can ping, Telnet can pass, and then see if there is no open 80 port on the virtual machine
  [[email protected] ~]# iptables -I INPUT -p tcp --dport 80 -j ACCEPT[[email protected] ~]# iptables -nvLChain INPUT (policy ACCEPT 58 packets, 3900 bytes)pkts bytes target     prot opt in     out     source               destination         0     0 ACCEPT     tcp  --  *      *       0.0.0.0/0            0.0.0.0/0            tcp dpt:80
• Write a Test php,vim/usr/local/apache2.4/htdocs/1.php

[[email protected] ~]# vim /usr/local/apache2.4/htdocs/1.php<?phpphpinfo();?>

• Open the host IP address/1.php on the physical machine browser, you can open the PHP information page, if you do not support PHP parsing, access to the file will show the source code.

• Troubleshooting

  • Check if Apache has loaded the PHP module

      [[email protected] ~]#/usr/local/apache2.4/bin/apachectl-mloaded Modules:core_module (Static) So_module (static) Http_module (static) Mpm_event_module (static) Authn_file_module ( Shared) Authn_core_module (shared) authz_host_module (shared) authz_groupfile_module (shared) Authz_user_module ( Shared) Authz_core_module (shared) access_compat_module (shared) auth_basic_module (shared) reqtimeout_module (shared) Filter_module (shared) mime_module (shared) log_config_module (shared) env_module (shared) headers_module (shared) Setenvif_module (shared) version_module (shared) unixd_module (shared) status_module (shared) autoindex_module (shared) Dir_module (shared) alias_module (shared) php7_module (shared)  
  • View PHP Module files
    [[email protected] ~]# ls /usr/local/apache2.4/modules/libphp7.so /usr/local/apache2.4/modules/libphp7.so[[email protected] ~]# ls /usr/local/apache2.4/modules/libphp5.so /usr/local/apache2.4/modules/libphp5.so
  • Check out these four items for Apache configuration file

#LoadModule php5_module        modules/libphp5.soLoadModule php7_module        modules/libphp7.soServerName www.example.com:80    AddType application/x-compress .Z    AddType application/x-gzip .gz .tgz    Addtype application/x-httpd-php .php<Directory />    AllowOverride none    Require all granted</Directory>

• "/usr/local/apache2.4/bin/apachectl-t" checks the configuration file for syntax errors
  • Configuring PHP7 parsing only needs to replace the PHP module loaded in the configuration file with Php7, the other same
  • Ctrl+r use: Reverse-search and invoke executed commands. (Reverse-i-search).
    How to use: Press CTRL+R after the command line into the "(Reverse-i-search)": "State, and then enter the used parameters, the corresponding command will be displayed directly, enter to execute the command.

Default virtual host for httpd

• Windows definition Hosts
  • C:\Windows\System32\drivers\etc\hosts
    192.168.21.128 www.abc.com www.123.com
  • Can ping check if it resolves to the IP you need
• One server can access multiple Web sites, each of which is a virtual host
• Concept: Domain name (hostname), DNS (domain name resolution System), hosts (domain name resolution for LAN)
• Any domain name resolves to this machine, the virtual host that can be accessed is the default virtual host
• Vim/usr/local/apache2/conf/httpd.conf

# Virtual hostsInclude conf/extra/httpd-vhosts.conf打开这个选项，启用虚拟主机配置文件/usr/local/apache2.4/conf/extra/httpd-vhosts.conf

• Vim/usr/local/apache2.4/conf/extra/httpd-vhosts.conf

  <virtualhost *:80> documentroot "/data/wwwroot/abc.com" ServerName abc.com serveralias www.abc.c Om www.123.com errorlog "logs/abc.com-error_log" Customlog "Logs/abc.com-access_log" common</virtualhost><v Irtualhost *:80> documentroot "/data/wwwroot/111.com" ServerName 111.com serveralias www.example.com errorl OG "logs/111.com-error_log" customlog "Logs/111.com-access_log" COMMON</VIRTUALHOST>  

• Create a Directory
  [[email protected] ~]# mkdir /data/wwwroot[[email protected] ~]# mkdir /data/wwwroot/abc.com[[email protected] ~]# mkdir /data/wwwroot/111.com
• Create a index.php file
  [[email protected] ~]# vim /data/wwwroot/abc.com/index.php[[email protected] ~]# vim /data/wwwroot/111.com/index.php<?phpecho "abc.com";
• /usr/local/apache2/bin/apachectl–t
• /usr/local/apache2/bin/apachectl Graceful
• Testing a virtual Host

• The abc.com here is the default virtual host

Extended

• All Apache hosts are pointing to the first
