nginx实验---lnmp实现多个虚拟主机，部署wordpress和phpmyadmin，并为后一个主机提供https

Posted 2020-10-10

lnmp实现多个虚拟主机，部署wordpress和phpmyadmin，并为后一个主机提供https。

 

一、安装nginx

 

方法一：编译安装

1.下载nginx程序包，传导至CentOS主机中，并解压。

2.进入解压目录

3.~]# ./configure --prefix=/usr/local/nginx--sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf--error-log-path=/var/log/nginx/error.log--http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid--lock-path=/var/lock/subsys/nginx.lock --user=nginx --group=nginx--with-http_ssl_module --with-http_v2_module --with-http_dav_module--with-threads --with-file-aio --with-http_stub_status_module

4. make -j 4 && make install

 

注意：1.启动服务需要事先创建nginx用户和nginx组；

2.若编译错误提示缺少编译软件可以 yum -y install gcc gcc-c++autoconf automake make

 

方法二：EPEL源的安装包

 [[email protected] ~]# cd /etc/yum.repos.d/

 [[email protected]]# vim nginx.repo

   [nginx]

name=nginx repo

baseurl=http://nginx.org/packages/centos/7/$basearch/

gpgcheck=0

enabled=1

[[email protected] yum.repos.d]# yum install -y nginx

 

二、创建虚拟机

[[email protected] ~]# mkdir -pv/var/www/vhost{1,2}

 

[[email protected] ~]# echo"www1.zrs.com" >> /var/www/vhost1/index.html

[[email protected] ~]# echo"www2.zrs.com" >> /var/www/vhost2/index.html

[[email protected] ~]# vim /etc/nginx/nginx.conf

server {

      listen       80;

      server_name  www1.zrs.com;

      location / {

          root   /var/www/vhost1;

          index index.php index.html index.htm;

      }

}

server {

      listen       80;

      server_name  www2.zrs.com;

       location / {

          root   /var/www/vhost2;

           index index.php index.html index.htm;

      }

}

 

[[email protected] ~]#nginx -t   ///检查语法没问题

[[email protected]~]# nginx -s reload     ///重启服务

 

客户端测试

三、安装php和mariadb，测试连接

 

[[email protected] ~]# yum install -y php-fpm mariadb-server mariadb

配置nginx支持php解析

[[email protected] ~]# vim /etc/nginx/nginx.conf

server {

      listen       80;

      server_name  www1.zrs.com;

      location / {

          root   /var/www/vhost1;

          index index.php index.html index.htm;

      }

       location ~ \.php$ {

           root           /var/www/vhost1;

           fastcgi_pass   127.0.0.1:9000;

           fastcgi_index  index.php;

           fastcgi_param SCRIPT_FILENAME /var/www/vhost1/$fastcgi_script_name;

           include        fastcgi_params;

       }

}

server {

      listen       80;

      server_name  www2.zrs.com;

      location / {

          root   /var/www/vhost2;

           index index.php index.html index.htm;

      }

       location ~ \.php$ {

           root           /var/www/vhost2;

           fastcgi_pass   127.0.0.1:9000;

           fastcgi_index  index.php;

           fastcgi_param SCRIPT_FILENAME /var/www/vhost2/$fastcgi_script_name;

           include        fastcgi_params;

       }

 

}

 

[[email protected] ~]# nginx -t   ///检查语法没问题

[[email protected] ~]# nginx -s reload     ///重启服务

修改两个主页index.html为index.php

并添加测试段内容：

<?php

       Phpinfo();

?>

客户端测试

 

创建数据库，授权用户，并刷新

MariaDB [(none)]> create database wpsdb;

MariaDB [(none)]> grant all on wpsdb.*TO ‘wpuser‘@‘172.16.%.%‘IDENTIFIED BY‘123456‘;

MariaDB [(none)]> create database pma;

MariaDB [(none)]> grant all on pma.* TO‘pmauser‘@‘172.16.%.%‘IDENTIFIED BY‘123456‘;

MariaDB [(none)]> FLUSH PRIVILEGES;

 

测试php和数据库能否正常连接

[[email protected] ~]# vim/var/www/vhost1/index.php

 

vhost2也同样设置成这样，相关数据库内容要改为pma的。

 

客户端测试

 

四、部署wordpress和phpmyadmin 

下载这两个应用并导入虚拟机中，分别解压

[[email protected] ~]# unzipwordpress-3.9-zh_CN.zip

[[email protected] ~]# tar -zxvfphpMyAdmin-4.0.10.20.tar.gz

 

1.部署wordpress

[[email protected] ~]# mv wordpress/var/www/vhost1/

[[email protected] ~]# cd /var/www/vhost1/wordpress/

[[email protected] wordpress]# mvwp-config-sample.php wp-config.php

[[email protected] wordpress]# vim wp-config.php   ///修改配置文件

/** WordPress数据库的名称*/

define(‘DB_NAME‘, ‘wpsdb‘);

 

/** mysql数据库用户名 */

define(‘DB_USER‘, ‘wpuser‘);

 

/** MySQL数据库密码 */

define(‘DB_PASSWORD‘, ‘123456‘);

 

/** MySQL主机 */

define(‘DB_HOST‘, ‘172.16.1.6‘);

 

客户端测试 

2. 部署phpmyadmin

[[email protected] ~]# mkdir/var/www/vhost2/phpmyadmin

 

[[email protected] ~]# mv phpMyAdmin-4.0.10.20-all-languages/*/var/www/vhost2/phpmyadmin/

[[email protected] ~]# cd /var/www/vhost2/phpmyadmin/

[[email protected] phpmyadmin]# mvconfig.sample.inc.php config.inc.php

[[email protected] phpmyadmin]# vim config.inc.php   ///修改这个文件中的下面一行配置为主机地址

$cfg[‘Servers‘][$i][‘host‘] = ‘172.16.1.6‘;

 

客户端测试

 

五、为phpmyadmin提供https

 

在主机上安装mod_ssl模块

[[email protected] ~]# yum -y install mod_ssl

 

切换到CA目录下，生成密钥和自签证书

[[email protected] ~]# cd /etc/pki/CA

[[email protected] CA]# (umask 077; openssl genrsa-out private/cakey.pem 2048)

Generating RSA private key, 2048 bit longmodulus

.......+++

...................................+++

e is 65537 (0x10001)

[[email protected] CA]# openssl req -new -x509 -keyprivate/cakey.pem -out cacert.pem

You are about to be asked to enterinformation that will be incorporated

into your certificate request.

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

There are quite a few fields but you canleave some blank

For some fields there will be a defaultvalue,

If you enter ‘.‘, the field will be leftblank.

-----

Country Name (2 letter code) [XX]:CN

State or Province Name (full name) []:Hebei

Locality Name (eg, city) [DefaultCity]:QinHuangdao

Organization Name (eg, company) [DefaultCompany Ltd]:Link

Organizational Unit Name (eg, section)[]:ops

Common Name (eg, your name or your server‘shostname) []:ca.link.com

Email Address []:[email protected]

 

提供辅助文件

[[email protected] CA]# touch index.txt

[[email protected] CA]# echo 01 > serial

 

生成私钥并且生成证书签署请求

 

[[email protected]~]# mkdir -pv /etc/nginx/ssl

[[email protected]~]# cd /etc/nginx/ssl

 

[[email protected] ssl]# (umask 077; openssl genrsa-out nginx.key 1024)   ///生成私钥

Generating RSA private key, 1024 bit longmodulus

....++++++

...............................++++++

e is 65537 (0x10001)

[[email protected] ssl]# openssl req -new -keynginx.key -out nginx.csr   ///生成证书请求

You are about to be asked to enterinformation that will be incorporated

into your certificate request.

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

There are quite a few fields but you canleave some blank

For some fields there will be a defaultvalue,

If you enter ‘.‘, the field will be leftblank.

-----

Country Name (2 letter code) [XX]:CN

State or Province Name (full name)[]:Hebei 

Locality Name (eg, city) [DefaultCity]:QinHuangdao

Organization Name (eg, company) [DefaultCompany Ltd]:Link

Organizational Unit Name (eg, section)[]:ops

Common Name (eg, your name or your server‘shostname) []:ca.link.com

Email Address []:[email protected]

 

Please enter the following ‘extra‘attributes

to be sent with your certificate request

A challenge password []:

An optional company name []:

 

签发证书

[[email protected] ssl]# cp nginx.csr /tmp/

[[email protected] ssl]# openssl ca -in/tmp/nginx.csr -out /etc/pki/CA/certs/nginx.crt   ///根据提示连续按两个“y”

[[email protected] ssl]# cp/etc/pki/CA/certs/nginx.crt /etc/nginx/ssl/  ///把签署好的证书发给请求者

 

修改nginx配置文件，添加支持ssl

[[email protected] ssl]# vim /etc/nginx/nginx.conf

server {

       listen       443 ssl;

       server_name  localhost;

       ssl_certificate     /etc/nginx/ssl/nginx.crt;

       ssl_certificate_key /etc/nginx/ssl/nginx.key;

       ssl_session_cache   shared:SSL:1m;

       ssl_session_timeout  5m;

       ssl_ciphers  HIGH:!aNULL:!MD5;

       ssl_prefer_server_ciphers  on;

       location / {

           root   html;

           index index.php index.html index.htm;

       }

}
