centos7-httpd虛擬主機

Apache虛擬主機：

一台WEB服務器發布單個網站會非常浪費資源，所以一台WEB服務器上會發布多個網站，

在一台服務器上發布多網站，也稱之為部署多個虛擬主機，WEB虛擬主機配置方法有三種：

    基於單IP多個Socket端口；

    基於多IP地址一個端口；

    基於單IP一個端口不同域名。

Apache WEB服務器安裝：

1）安裝apr：

[root@localhost src]# wget http://archive.apache.org/dist/apr/apr-1.5.2.tar.gz
[root@localhost src]# tar xf apr-1.5.2.tar.gz
[root@localhost src]# cd apr-1.5.2
[root@localhost apr-1.5.2]# ./configure --prefix=/usr/local/apr
[root@localhost apr-1.5.2]# make && make install

2)安裝apr-util：

[root@localhost src]# wget http://archive.apache.org/dist/apr/apr-util-1.5.4.tar.gz
[root@localhost src]# tar xf apr-util-1.5.4.tar.gz 
[root@localhost src]# cd apr-util-1.5.4
[root@localhost apr-util-1.5.4]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
[root@localhost apr-util-1.5.4]# make && make install

3）編譯httpd-2.4：

[root@localhost src]# yum -y install pcre-devel openssl-devel libevent-devel
[root@localhost src]# wget http://archive.apache.org/dist/httpd/httpd-2.4.10.tar.bz2
[root@localhost src]# tar xf httpd-2.4.10.tar.bz2
[root@localhost src]# cd httpd-2.4.10
[root@localhost httpd-2.4.10]# ./configure --prefix=/usr/local/apache --enable-so --enable-ssl --enable-rewrite --enable-defalte --enable-modules=most --enable-mpms-shared=all --with-mpm=prefork --with-pcre --with-zlib --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/
[root@localhost httpd-2.4.10]# make && make install

4）啟動httpd：

[root@localhost ~]# echo 'export PATH=/usr/local/apache/bin:$PATH' > /etc/profile.d/httpd.sh
[root@localhost ~]# source /etc/profile.d/httpd.sh

基於一個端口不同域名配置：

1）創建虛擬主機配置文件httpd-vhosts.conf，該文件默認已存在，只需去掉httpd.conf主配置文件中#號即可

[root@localhost ~]# vim /usr/local/apache/conf/httpd.conf

2)配置虛擬主機：

[root@localhost ~]# vim /usr/local/apache/conf/extra/httpd-vhosts.conf

<VirtualHost *:80>						#監聽所有網卡的80端口 DocumentRoot "/usr/local/apache/htdocs/www1" #虛擬主機發布目錄 ServerName www.a.com #虛擬主機完整域名  ErrorLog "logs/www.a.com-error_log" #錯誤日志路徑 CustomLog "logs/www.a.com-access_log" common #訪問日志路徑 <Location /server-status> #提供狀態信息，且僅允許tom用戶訪問 SetHandler server-status AuthType basic AuthName "Fortom" AuthUserFile "/usr/local/apache/conf/.htpasswd" Require user tom </Location> </VirtualHost> <VirtualHost *:80> DocumentRoot "/usr/local/apache/htdocs/www2" ServerName www.b.com ErrorLog "logs/www.b.com-error_log" CustomLog "logs/www.b.com-access_log" combined <Directory "/usr/local/apache/htdocs/www2"> #設置www2目錄權限，不允許192.168.2.0網段任意主機訪問 Options None AllowOverride None Order deny,allow Deny from 192.168.2.0/24 </Directory> </VirtualHost>

3）創建虛擬主機發布目錄：

[root@localhost ~]# mkdir -p /usr/local/apache/htdocs/{www1,www2}
[root@localhost ~]# echo '<h1>www.a.com Pages</h1>' > /usr/local/apache/htdocs/www1/index.html
[root@localhost ~]# echo '<h1>www.b.com Pages</h1>' > /usr/local/apache/htdocs/www2/index.html

4）創建tom用戶：
[root@localhost ~]# htpasswd -cm /usr/local/apache/conf/.htpasswd tom
[root@localhost ~]# apachectl restart

 5）測試虛擬主機：

修改客戶端hosts文件，域名能夠解析到服務器ip

6）測試server-status：

7）測試www2訪問權限：

 

https加密配置：

建立私有CA：

生成私鑰：

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

#生成自簽證書：

[root@localhost CA]# openssl req -new -x509 -key private/cakey.pem -out cacert.pem
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) []:bj
Locality Name (eg, city) [Default City]:bj
Organization Name (eg, company) [Default Company Ltd]:ym
Organizational Unit Name (eg, section) []:Ops
Common Name (eg, your name or your server's hostname) []:www.a.com
Email Address []:[e-mail]

#提供輔助文件：
[root@localhost CA]# touch index.txt
[root@localhost CA]# echo 01 >serial

#生成私鑰：
[root@localhost CA]# mkdir /usr/local/apache/ssl
[root@localhost CA]# cd /usr/local/apache/ssl
[root@localhost ssl]# (umask 077; openssl genrsa -out httpd.key 1024)

#生成證書請求：

[root@localhost ssl]# openssl req -new -key httpd.key -out httpd.csr

修改配置文件，啟用SSL模塊：

[root@localhost ssl]# vim /usr/local/apache/conf/httpd.conf

LoadModule ssl_module modules/mod_ssl.so

Include conf/extra/httpd-ssl.conf

SSL配置：

[root@localhost ssl]# vim /usr/local/apache/conf/extra/httpd-ssl.conf 

Listen 443
<VirtualHost _default_:443>
    DocumentRoot "/usr/local/apache/htdocs/www1"
    ServerName www.a.com:443
    SSLCertificateFile /usr/local/apache/ssl/httpd.crt
    SSLCertificateKeyFile /usr/local/apache/ssl/httpd.key
    <Directory "/usr/local/apache/htdocs/www1">
        SSLOptions +StdEnvVars
        AllowOverride None
        Require all granted
    </Directory>
