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 [[email protected] ~]# cd /etc/pki/CA/ [[email protected] 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 [[email protected] CA]# (umask 077;openssl genrsa -out private/cakey.pem 2048) Generating RSA private key, 2048 bit long modulus .....+++ .......+++ e is 65537 (0x10001) [[email protected] 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 []:[email protected] [[email protected] 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 [[email protected] CA]# touch /etc/pki/CA/index.txt [[email protected] CA]# touch /etc/pki/CA/serial [[email protected] 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 [[email protected] ~]# mkdir /etc/httpd/ssl [[email protected] ~]# cd /etc/httpd/ssl [[email protected] ssl]# (umask 077;openssl genrsa -out httpd.key 2048) Generating RSA private key, 2048 bit long modulus ..........+++ ....................................................................+++ e is 65537 (0x10001) [[email protected] 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 [[email protected] 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 []:[email protected] Please enter the following 'extra' attributes to be sent with your certificate request A challenge password []: An optional company name []: [[email protected] ssl]# ls httpd.csr httpd.key [[email protected] ssl]# scp httpd.csr [email protected]:/tmp/ [email protected]'s password: httpd.csr 100% 1050 1.0KB/s 00:00 [[email protected] 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 [[email protected] 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) Validity Not Before: Aug 23 10:55:56 2017 GMT Not After : Aug 23 10:55:56 2018 GMT Subject: countryName = CN stateOrProvinceName = Hubei organizationName = Gump Ltd organizationalUnitName = Ops commonName = web.gump.com emailAddress = [email protected] X509v3 extensions: X509v3 Basic Constraints: CA:FALSE Netscape Comment: OpenSSL Generated Certificate X509v3 Subject Key Identifier: 7A:D2:B5:60:3D:13:27:33:C4:F5:02:DC:AC:44:BB:0F:F9:32:00:71 X509v3 Authority Key Identifier: keyid:5A:9A:54:2F:9C:91:3E:D6:BE:CC:22:68:50:C6:83:EB:23:AD:AC:AF Certificate is to be certified until Aug 23 10:55:56 2018 GMT (365 days) Sign the certificate? [y/n]:y 1 out of 1 certificate requests certified, commit? [y/n]y Write out database with 1 new entries Data Base Updated [[email protected] CA]# （2）将证书传回请求者 [[email protected] CA]# scp /tmp/web.gump.com.crt [email protected]:/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. [email protected]'s password: web.gump.com.crt 100% 4595 4.5KB/s 00:00 [[email protected] 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
[[email protected] 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
[[email protected] ~]# mkdir -pv /www/htdocs/vhosts{1,2,3}
[[email protected] ~]# unzip phpMyAdmin-4.0.10.20-all-languages.zip
[[email protected] ~]# cp phpMyAdmin-4.0.10.20-all-languages /www/htdocs/vhosts1/
[[email protected] ~]# ln -sv phpMyAdmin-4.0.10.20-all-languages pma
(4)配置httpd.conf
[[email protected] 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
[[email protected] ~]# vim /etc/httpd/conf.d/httpd-vhost1.conf
<VirtualHost 172.16.20.244:80>
ServerAdmin web.gump.com
DocumentRoot "/www/htdocs"
<Directory "/www/htdocs/vhosts1/pma">
Options None
AllowOverride None
Require all granted
</Directory>
</VirtualHost>
[[email protected] ~]# 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
[[email protected] ~]# vim /etc/httpd/conf.d/httpd-vhost2.conf
<VirtualHost 172.16.20.245:80>
ServerAdmin web2.gump.com
DocumentRoot "/www/htdocs"
<Directory "/www/htdocs/vhosts2">
Options None
AllowOverride None
Require 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
[[email protected] ~]# ip addr add 172.16.20.245/24 dev ens33
[[email protected] ~]# ip addr show dev ens33
[[email protected] ~]# ip add show dev ens33
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:44:e2:e3 brd ff:ff:ff:ff:ff:ff
inet 172.16.20.244/24 brd 172.16.20.255 scope global ens33
valid_lft forever preferred_lft forever
inet 172.16.20.245/24 scope global secondary ens33
valid_lft forever preferred_lft forever
inet6 fe80::d846:2237:6188:97fe/64 scope link tentative dadfailed
valid_lft forever preferred_lft forever
inet6 fe80::a0de:8503:69c8:5595/64 scope link tentative dadfailed
valid_lft forever preferred_lft forever
inet6 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
[[email protected] ~]# unzip wordpress-4.7.4-zh_CH.zip
[[email protected] ~]# cp wordpress /www/htdocs/vhosts2/
4、配置虚拟主机2的wordpress的配置文件
[[email protected] ~]# 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
[[email protected] ~]# cd /www/htdocs/vhost2/wordpress
[[email protected] ~]# cp wp-config-sample.php wp-config.php
[[email protected] ~]# 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
5、查看配置效果
写的比较潦草，如有遗漏错误和争议之处，欢迎大家的批评指正和讨论，谢谢。
