测试目标：

三个虚拟主机，要求如下

vhost1： phpMyAdmin, 同时提供https服务；

vhost2: wordpress

配置过程：

一、配置vhost1

1、首先配置vhost1，先搭建私有CA

在172.16.20.242上搭建私有CA：
(1) 创建私钥，公钥无需处理
[root@ca ~]# cd /etc/pki/CA/
[root@ca CA]# (umask 077;openssl genrsa -out private/cakey.pem 2048)
Generating RSA private key, 2048 bit long modulus
.....+++
.......+++
e is 65537 (0x10001)(2) 生成自签证书，填写相关证书信息
[root@ca CA]# (umask 077;openssl genrsa -out private/cakey.pem 2048)
Generating RSA private key, 2048 bit long modulus
.....+++
.......+++
e is 65537 (0x10001)
[root@ca CA]# openssl req -new -x509 -key private/cakey.pem -out cacert.pem -days 3655
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.
-----
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:Hubei
Locality Name (eg, city) [Default City]:Hubei
Organization Name (eg, company) [Default Company Ltd]:Gump Ltd
Organizational Unit Name (eg, section) []:Ops
Common Name (eg, your name or your server's hostname) []:ca.gump.com
Email Address []:caadmin@gump.com
[root@ca CA]#
// 需要注意的是，证书格式必须为pem格式（3）创建签署证书环境
[root@ca CA]# touch /etc/pki/CA/index.txt
[root@ca CA]# touch /etc/pki/CA/serial
[root@ca CA]# echo 01 > /etc/pki/CA/serial

2、在web主机上生成证书请求，并发送证书请求到CA主机

在172.16.20.244生成证书请求：
（1）生成密钥，并保存到应用此证书的服务的配置文件目录下
[root@web ~]#  mkdir /etc/httpd/ssl
[root@web ~]#  cd /etc/httpd/ssl
[root@web ssl]# (umask 077;openssl genrsa -out httpd.key 2048)
Generating RSA private key, 2048 bit long modulus
..........+++
....................................................................+++
e is 65537 (0x10001)
[root@web ssl]# ls
httpd.key(2) 生成证书签署请求，填写相关信息需要注意的是，除了主机地址和邮箱地址，其它需要保持一致
[root@web ssl]# openssl req -new -key httpd.key -out httpd.csr
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.
-----
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:Hubei
Locality Name (eg, city) [Default City]:Hubei
Organization Name (eg, company) [Default Company Ltd]:Gump Ltd
Organizational Unit Name (eg, section) []:Ops
Common Name (eg, your name or your server's hostname) []:web.gump.com
Email Address []:webadmin@gump.comPlease enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
[root@web ssl]# ls
httpd.csr  httpd.key
[root@web ssl]# scp httpd.csr root@172.16.20.242:/tmp/
root@172.16.20.242's password:
httpd.csr                                                          100% 1050     1.0KB/s   00:00
[root@web ssl]#

3、签署证书请求，将证书请求发送回web主机

（1）签署证书请求
[root@ca CA]# openssl ca -in /tmp/httpd.csr -out /tmp/web.gump.com.crt -days 365
Using configuration from /etc/pki/tls/openssl.cnf
Check that the request matches the signature
Signature ok
Certificate Details:Serial Number: 1 (0x1)ValidityNot Before: Aug 23 10:55:56 2017 GMTNot After : Aug 23 10:55:56 2018 GMTSubject:countryName               = CNstateOrProvinceName       = HubeiorganizationName          = Gump LtdorganizationalUnitName    = OpscommonName                = web.gump.comemailAddress              = webadmin@gump.comX509v3 extensions:X509v3 Basic Constraints: CA:FALSENetscape Comment: OpenSSL Generated CertificateX509v3 Subject Key Identifier: 7A:D2:B5:60:3D:13:27:33:C4:F5:02:DC:AC:44:BB:0F:F9:32:00:71X509v3 Authority Key Identifier: keyid:5A:9A:54:2F:9C:91:3E:D6:BE:CC:22:68:50:C6:83:EB:23:AD:AC:AFCertificate is to be certified until Aug 23 10:55:56 2018 GMT (365 days)
Sign the certificate? [y/n]:y1 out of 1 certificate requests certified, commit? [y/n]y

Data Base Updated
[root@ca CA]#
（2）将证书传回请求者
[root@ca CA]# scp /tmp/web.gump.com.crt root@172.16.20.244:/etc/httpd/ssl
The authenticity of host '172.16.20.244 (172.16.20.244)' can't be established.
RSA key fingerprint is 5a:10:33:a2:bf:5b:06:82:25:01:fb:c2:74:93:34:95.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '172.16.20.244' (RSA) to the list of known hosts.
root@172.16.20.244's password:
web.gump.com.crt                                                   100% 4595     4.5KB/s   00:00
[root@ca CA]#

4、配置httpd支持使用ssl

（1）查看当前web主机是否已安装mod_ssl模块，如果没有安装，则必须先安装mod_ssl模块
（2）配置ssl配置文件
[root@web ssl]# vim /etc/httpd/conf.d/ssl.conf
修改如下选项:
<VirtuaHost 172.16.20.244:443>
// 因为ssl会话是基于IP地址建立的，若有多个IP地址，则需指定地址，若只有一个地址，则无需修
改，保持"*"即可；
DocumentRoot "/www/htdocs"
// 此目录为虚拟主机vhost1的中心目录，即网页文件存放位置
ServerName web.gump.com:443
// 当前主机名
ErrorLog /logs/pma_error_log
// 错误日志存放位置
Transferlog logs/pma_access_log
// 访问日志存放目录
SSLCertificateFile /etc/httpd/ssl/web.gump.com.crt
// 服务器证书存放目录
SSlCertificateKeyFile /etc/httpd/ssl/httpd.key
// 证书私钥存放目录
(3)配置phpMyadmin网页文件
[root@localhost  ~]#    mkdir -pv /www/htdocs/vhosts{1,2,3}
[root@localhost ~]#  unzip phpMyAdmin-4.0.10.20-all-languages.zip
[root@localhost ~]#  cp phpMyAdmin-4.0.10.20-all-languages /www/htdocs/vhosts1/
[root@localhost  ~]#    ln -sv phpMyAdmin-4.0.10.20-all-languages pma
(4)配置httpd.conf
[root@localhost conf]# vim httpd.conf
ServerName Localhost:80
DocumentRoot "/www/htdocs"
<Directory "/www/htdocs">
// Directory 指定的目录要和DocumentRoot一致
(5)配置虚拟主机配置文件
[root@localhost ~]#  vim /etc/httpd/conf.d/httpd-vhost1.conf
<VirtualHost 172.16.20.244:80>ServerAdmin web.gump.comDocumentRoot "/www/htdocs"<Directory "/www/htdocs/vhosts1/pma">Options NoneAllowOverride NoneRequire all granted</Directory>
</VirtualHost>
[root@localhost ~]#   systemctl reload httpd.service

查看配置效果

二、配置虚拟主机2

1、配置虚拟主机2的配置文件
[root@localhost ~]#   vim /etc/httpd/conf.d/httpd-vhost2.conf
<VirtualHost 172.16.20.245:80>ServerAdmin web2.gump.comDocumentRoot "/www/htdocs"<Directory "/www/htdocs/vhosts2">Options NoneAllowOverride NoneRequire all granted</Directory>
</VirtualHost>
2、为虚拟主机2配置IP地址
由于是虚拟机，没有多张网卡使用ip命令添加地址达到多IP效果
[root@localhost ~]#   ip addr add 172.16.20.245/24 dev ens33
[root@localhost ~]#   ip addr show dev ens33
[root@localhost ~]# ip add show dev ens33
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000link/ether 00:0c:29:44:e2:e3 brd ff:ff:ff:ff:ff:ffinet 172.16.20.244/24 brd 172.16.20.255 scope global ens33valid_lft forever preferred_lft foreverinet 172.16.20.245/24 scope global secondary ens33valid_lft forever preferred_lft foreverinet6 fe80::d846:2237:6188:97fe/64 scope link tentative dadfailed valid_lft forever preferred_lft foreverinet6 fe80::a0de:8503:69c8:5595/64 scope link tentative dadfailed valid_lft forever preferred_lft foreverinet6 fe80::9a1a:88f0:c9cf:41bd/64 scope link tentative dadfailed valid_lft forever preferred_lft forever
3、配置虚拟主机2的网页文件
[root@localhost ~]#  unzip wordpress-4.7.4-zh_CH.zip
[root@localhost ~]#  cp wordpress /www/htdocs/vhosts2/
4、配置虚拟主机2的wordpress的配置文件
[root@localhost ~]# mysql
MariaDB [(none)]> CREATE DATABASE mydb1;
MariaDB [(none)]> exit
// 连接wordpress必须要配置正确的数据库及用户名密码，所以需要实现创建好数据库
[root@localhost ~]#   cd /www/htdocs/vhost2/wordpress
[root@localhost ~]#   cp wp-config-sample.php wp-config.php
[root@localhost ~]#   vim wp-config.php
define('DB_NAME','mydb1');  // 数据库为事先创建好的mydb1
define('DB_USER','root');   // 用户名为root
define('DB_PASSWORD','');   // root密码默认为空
