基于CentOS7实现LAMP(上)

基于CentOS7实现LAMP(上)

 

情景模式:

1php以模块方式运行

 提供两个虚拟主机;

                                     web1: phpMyAdmin, 同时提供ssl

                                     web2: wordpress;

                                    

限于篇幅,本文的php采用模块方式运行于httpd中,在下一篇博文:基于CentOS7实现LAMP(下),我会再介绍phpfpm方式,即fastCGI方式运行的实现,敬请期待。

为便于理解,文中##处均是我的注解

 

##首先安装基础软件工具包                  

[root@localhost yum.repos.d]# yum groupinstall  "Development Tools" -y

 

##然后安装httpd服务

[root@localhost yum.repos.d]# yum install httpd -y

 

##安装mariadb

[root@localhost yum.repos.d]# yum install -y mariadb-server mariadb-devel mairadb

 

##安装php,以httpd模块方式

[root@localhost yum.repos.d]# yum install -y php php-devel php-mysql

yum install php php-devel php-mysql

 

##修改httpd.conf文件,配置两个虚拟主机站点

#vim /etc/httpd/conf/httpd.conf

 

         ServerName web.test.net:80

         ##DocumentRoot "/var/www/html"

 

#cd /etc/httpd/conf.modules.d

#vim 00-mpm.conf

         LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

 

 

##添加对php网页的支持    

#cd /etc/httpd/conf.d

#[root@web conf.d]# vim php.conf

       

AddType application/x-httpd-php .php

AddType application/x-httpd-php-source .phps

 

DirectoryIndex index.php

 

<Directory "/www/web1">

  options none

  allowoverride none

  require all granted

</Directory>

 

<Directory "/www/web2">

  options none

  allowoverride none

  require all granted

</Directory>

 

 

[root@web conf.d]# vim vhosts.conf

<VirtualHost *:80>

  ServerName web1.test.net

  DocumentRoot /www/web1/

</VirtualHost>

 

<VirtualHost *:80>

  ServerName web2.test.net

  DocumentRoot /www/web2/

</VirtualHost>

 

##启动httpd

[root@web conf]# httpd -t

Syntax OK

[root@web conf]#

[root@web conf]# systemctl start httpd.service

 

[root@web conf]# ss -ntlp | grep httpd

LISTEN     0      128         :::80                      :::*                   users:(("httpd",pid=9

2530,fd=4),("httpd",pid=92529,fd=4),("httpd",pid=92528,fd=4),("httpd",pid=92527,fd=4),("httpd",pid=92

526,fd=4),("httpd",pid=92524,fd=4))

[root@web conf]#

 

 

##实验环境为避免影响,关闭本机的selinux及防火墙服务

[root@web /]# getenforce

Enforcing

[root@web /]# setenforce 0

[root@web /]#

[root@web /]# systemctl stop firewalld.service

 

[root@web /]# systemctl disable firewalld.service

Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.

[root@web /]#

[root@web /]# vim /etc/selinux/config

SELINUX=disabled

##检查网页正常否

web2php.jpg

##安装phpMyAdmin

[root@web setup]# tar xzvf phpMyAdmin-4.4.15.7-all-languages.tar.gz -C /www/web1/

[root@web web1]# mv phpMyAdmin-4.4.15.7-all-languages pma

[root@web pma]# cp config.sample.inc.php config.inc.php

[root@web pma]# vim config.inc.php

 

[root@web pma]# vim /etc/httpd/conf/httpd.conf

<Directory "/www/web1/pma">

  options none

  allowoverride none

  require all granted

</Directory>

 

[root@web pma]# systemctl reload httpd.service

 

 

[root@web modules]# systemctl start mariadb

 

##修改mysqlroot密码为'redhat'

[root@web modules]# mysql

##安装wordpress

[root@web LAMP]# unzip wordpress-4.5.3-zh_CN.zip

[root@web LAMP]# cd wordpress/

[root@web wordpress]#

[root@web LAMP]# mv wordpress /www/web2/

[root@web LAMP]# cd /www/web2/wordpress

##测试

##以下为为web1.test.net站点提供ssl功能,简单起建,将自建的证书服务器都放在本台机器上了。

因为搭建自建证书及https站点不是本文重点,所以只是简单show一下操作步骤,有兴趣了解详细内容的同学,请移步到我的另一篇博文:自建CA搭建SSL加密网站

 

##自建证书

[root@web wordpress]# cd /etc/pki/CA

You have new mail in /var/spool/mail/root

[root@web CA]# ls

certs  crl  newcerts  private

[root@web CA]# (umask 077; openssl genrsa -out private/cakey.pem 2048)

Generating RSA private key, 2048 bit long modulus

………………………………………………………………………………………………………+++

………………..+++

e is 65537 (0x10001)

[root@web CA]# touch index.txt

[root@web CA]# echo 01 > serial

[root@web CA]#

[root@web CA]# openssl req -new -x509 -key private/cakey.pem -out cacert.pem -days 7300

You are about to be asked to enter information that will be incorporated

into your certificate request.

What you are about to enter is what is called a Distinguished Name or a DN.

There are quite a few fields but you can leave some blank

For some fields there will be a default value,

If you enter '.', the field will be left blank.

autoindex.conf  php.conf  README  ssl.conf  userdir.conf  vhosts.conf  welcome.conf

[root@web conf.d]# cp ssl.conf{,.bak}

[root@web conf.d]# vim ssl.conf

 

##添加ssl站点设置

<VirtualHost 172.16.10.1:443>

SSLEngine on

##SSLCertificateFile /etc/pki/tls/certs/localhost.crt

SSLCertificateFile /etc/httpd/ssl/web1.test.net.crt

 

##SSLCertificateKeyFile /etc/pki/tls/private/localhost.key

SSLCertificateKeyFile /etc/httpd/ssl/httpd.key

 

DocumentRoot "/www/web1"

ServerName web1.test.net

 

 

<Directory "/www/web1/">

   require all granted

</Directory>

 

<Directory "/www/web1/pma/">

##重启服务

[root@web conf.d]# httpd -t

Syntax OK

[root@web conf.d]# systemctl restart httpd.service

[root@web conf.d]#

 

[root@web conf.d]# ss -ntlp  | grep 443

LISTEN     0      128         :::443                     :::*                   users:(("httpd",pid=7621,fd=6),("httpd",pid=7620,fd=6),("httpd",pid=7619,fd=6),("httpd",pid=7618,fd=6),("httpd",pid=7617,fd=6),("httpd",pid=7615,fd=6))

[root@web conf.d]#

 

 

##检查网站

证书信息.png

##证书并未在客户端导入,所以会有出错的警示信息,请忽略,呵呵。重点是已经能够以https访问站点了。。。

##至此,网站创建完毕,测试使用正常。
